TYPO3 10.4: tx_news content elements rendering error - typo3

I am updating TYPO3 from Version 8 to 9 and 10. Now there is one error, I am not able to find a solution.
In tx_news details view I am using custom fluid templates. In TYPO3 8 and 9 everything works fine. In TYPO3 10.4 I get an error when showing the detail page:
(1/1) #1381512761 TYPO3\CMS\Core\Type\Exception\InvalidEnumerationValueException
Invalid value "FILE" for enumeration "TYPO3\CMS\Core\DataHandling\TableColumnSubType"
If I remove this code for content elements in the fluid template, the page will be shown without errors:
<f:if condition="{newsItem.contentElements}">
<!-- content elements -->
<f:cObject typoscriptObjectPath="lib.tx_news.contentElementRendering">{newsItem.contentElementIdList}</f:cObject>
</f:if>
As I'm using content elements, I need this code.
You can see the error at the moment here:
https://asienhaus104.der-koenig.net/aktuelles/detail/spenden-fuer-die-suedostasien
I tried lots of variants to solve this, but still the error will be there when I insert the fluid output for content elements.

It seems you have a content element inside which is rendered in TypoScript with the FILE object (which was removed in v10). Take a look in your TypoScript (TypoScript object browser is best for this) and search for FILE objects (and replace them).
Here you can find the deprecation notice and a migration suggestion: https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/9.5/Deprecation-85970-FileContentObject.html

How to have multiple sections with images in a FluidTYPO3 flux form with TYPO3 10?

I have been using FluidTYPO3 (flux and vhs) to run TYPO3 web pages for many years now. With TYPO3 10, I face a major problem. I'll quickly write about my use case, how I solved it so far, and then what the problem with 10 LTS is.
Use case:
I want to have a content element template for a timeline using FluidTYPO3/flux. Each "point" on the timeline should have a heading, some text, and optionally some images. All in all, pretty basic (or so I thought).
Solution so far (TYPO3 <= 9):
Timeline elements are sections. Images are using flux:field.file.
Simplified example of the form:
<flux:form id="timeline" label="timeline">
<flux:form.section name="timeline" label="Timeline">
<flux:form.object name="element" label="Element">
<flux:field.input name="title" label="Heading" />
<flux:field.text name="label" label="Text" enableRichText="TRUE" />
<flux:field.file name="images" label="Pictures" allowed="jpg,png,svg" multiple="TRUE" maxItems="50" size="5" showThumbnails="TRUE"
/>
</flux:form.object>
</flux:form.section>
</flux:form>
With this, multiple elements can be created on the timeline and each of them can have its own set of images.
Problem in TYPO3 10:
The technology (TCA group fields to select files) that flux:field.file relies on was deprecated in TYPO3 9 and removed in TYPO3 10, see this notice. That is one of the reasons why flux:field.file was also marked deprecated and is going to be removed in TYPO3 10.
The TYPO3 deprecation notice says to use FAL relations instead. Of course, flux can also do this with flux:field.inline.fal. However, you can only have one FAL field per FlexForm. This precludes its usage in sections, since all sections would share the same images. This limitation is known for some time - see this bug report for example - but has never been fixed. It is also why I initially chose not to use FAL fields. Using bare file fields was the recommended workaround at the time.
Question:
So - how is everyone doing it? How to add multiple image fields to a flexform in TYPO3 10?
EDIT: More specifically, how to add an image field as part of a Flexform section that can contain multiple child records (resulting in multiple image fields)?
Note: I know that I can get a "file-like" field back by using an input field with inputLink renderType (like this), but as far as I can tell it does not allow to link multiple images.
I've found another workaround that might be appropriate for some use cases:
It is still possible to use flux:field.file fields if the useFalRelation parameter set to true, even on TYPO3 v10 LTS and in repeatable FlexForm sections. This will then put sys_file record IDs separated by comma into the field instead of raw filenames. They can be used as src argument for, e.g., f:image just as well as the filename, so the CE templates itself do not have to be modified. All existing CEs that had useFalRelation set to false need to be migrated though so that the filenames are replaced with sys_file UIDs.
This is a bit better than the inputLink workaround since it allows multiple images.
It seems the only workaround with TYPO3 core onboard methods is to go for a Flux-Container having a single column containing simple default "Text with image" or "text with media" elements and then to just ignore additional options of those elements and to just render the necessary fields.
With Gridelements this is called a "functional container", since the container determines the behaviour and appearance of those elements, while the elements themselves don't have to be custom elements at all.
Additionally this makes access to the content of those elements - i.e. while doing a search query - much easier.
The bug report you mentioned already contains the solutions, since the actual problem described there is that FAL fields in a flexform are using the same name.
So instead of
image
according to the bug report there should be
settings.foreground.image
which is of course not working, since the dot is part of the path but not of the name.
But actually replacing the dot with an underscore and using some suffixes within the same flexform tab should do the trick:
settings.foreground.settings_foreground_image
settings.foreground.settings_foreground_image2
This way you make sure that
The field names within your flexform are unique
The actual field name within the sys_file_reference entry already contains the full path information
You can use that information to fetch images i.e. within a DataProcessor and still know the FlexForm field they actually belong to
Sitll I would recommend to fully move away form FlexForms (and thus Flux too) in favor of "real" fields in the database table.
If you currently use the flux:field.file element at typo3 10 with the useFalRelation=1 you can replace it by the flux:field element. It is not deprecated and works in combination with the flux:form.object element
Following example:
<flux:field.file
allowed="jpg,png,svg,gif"
exclude="false"
label="MyLabel"
name="myname"
showThumbnails="1"
useFalRelation="1"
maxItems="1"
minItems="1"
/>
Can be replaced with:
<flux:field type="input" name="myname" label="MyLabel"
config="{
type: 'group',
size: 1,
internal_type: 'db',
use_fal_relation: 1,
allowed: 'sys_file',
maxitems: 1,
minitems: 0,
show_thumbs: 1,
appearance: {
elementBrowserAllowed: 'jpg,png,svg,gif',
elementBrowserType: 'file'
}
}
"/>

Fluid TYPO3: Get flux variables from other page

I try to display a value from a subpage on my main page. This what I defined in the subpage:
<flux:field.select
name="ampel"
label="Ampel"
items="{
0:{0:'Rot',1:'rot'},
1:{0:'Gelb',1:'gelb'},
2:{0:'Grün',1:'grun'}
}"
/>
I need to get the value of {ampel} on the main page in an other fluid-component.
I tried this solution:
Fluid Typo3 - How to get variables definded via flux from different page uids
but the field tx_fed_page_flexform is empty. I think they changed the storage in the newer TYPO3 versions. I also can't find the values in the database. Shouldn't they be in the tt_content table?
I hope somebody can help me.

TYPO3 9.5.15 with gridelements and t3sbootstrap not working

I have a new TYPO3 9.5.15 installation and added gridelements 9.5.0 and t3sbootstrap 4.4.5 to make content elements with 3 columns in a own 1 column backendlayout which is defined in PageTsConfig.
In older TYPO3 versions, this is working fine (i.e TYPO3 7) but in TYPO3 9 I get the following error in FE:
Tried resolving a template file for controller action "Standard->three_columns" in format ".html", but none of the paths contained the expected template file (Standard/Three_columns.html). The following paths were checked:
xxx/typo3/sysext/fluid_styled_content/Resources/Private/Templates/, xxx/typo3conf/ext/gridelements/Resources/Private/Templates/, xxx/typo3conf/ext/t3sbootstrap/Resources/Private/Templates/Content/, xxx/typo3conf/ext/t3sbootstrap/Resources/Private/Templates/, ,
I've double checked and can confirm, that both, gridelements and t3sbootstrap are included in the roottemplate of the website.
As far as I found out, the templates are available in xxx/typo3conf/ext/t3sbootstrap/Resources/Private/Templates/Gridelements/
but are called ThreeColumns.html
Has anyone an idee what causes the error and how to resolve it?
Thanks in advance
At a first look it seems that there are 2 problems with your combination here:
The message "Standard->three_columns" points to a wrong static template, so I guess you included the new DataProcessing static of Gridelements, while t3sbootstrap depends on the old Plugin and USER based static.
The root path xxx/typo3conf/ext/t3sbootstrap/Resources/Private/Templates/Gridelements/ is missing in your setup.
At a second look it might even be enough to change the Gridelements static, since t3sbootstrap takes care of the root path based on that setup.

Typo3 change how objects are rendered (typo3 beginner)

I'm fairly new to typo3 and I have an issue that i don't find an explanation on how to change it. I'm sure there are already some helpful tutorials but i have issues finding them.
I am making a website and I have already made a template for fontend and backend.
It is a very simple test template that consists only of one slider and one text element.
The slider is handmade and should have the following layout:
<section class="custom-slider">
<img src="img1.jpg">
<img src="img2.jpg">
...
</section>
Thought easy, i have my slider place in my template, just need to add plain images.
but typo3 gives me:
<section class="custom-slider">
<div id="c3" class="frame frame-default frame-type-image frame-layout-0"><header><h2 class=""></h2></header><div class="ce-image ce-center ce-above"><div class="ce-gallery" data-ce-columns="1" data-ce-images="1"><div class="ce-outer"><div class="ce-inner"><div class="ce-row"><div class="ce-column"><figure class="image"><img class="image-embed-item" src="fileadmin/_processed_/1/2/csm_slider1_c3fdcdcaf5.jpg" width="600" height="187" alt="" /></figure></div></div></div></div></div></div></div>
</section>
Now i search how i can make my own custom elements or render existing elements different. I have found a lot of tutorials but they all are based on 'Extension Builder' or 'Builder' and require a custom extention. These don't seem to work on Typo3 8.7.x. Is there a different solution or can someone give me a good tutorial link?
Thank you in advanst:)
Ps: since i will have the same problem with styled text elements i would like to ask if there is a way to declare in the themplate how different predeterment elements are rendered?
In TYPO3 8.7 (I assume) your rendering is done with FSC (fluid_styled_content), so you have to understand the mechanism of FSC to render a CE (ContentElement).
As the name suggests Fluid is used. Fluid uses different templates organized in three categories (each with it's own folder):
Layouts
Templates
Partials
The call goes to a template (in the folder 'templates') where a tag can be inserted to use a specific layout (from floder 'Layouts'). if this tag is given the rendering starts with the given layout. In the layout different sections and partials can be called. Sections belong to the template, partials need to have an own partial file (in folder 'Partials').
You can override single files from the given declaration to individulize the behaviour.
In your example you may evaluate the field layout in layout, template and partial to avoid the default wrapping of any content (your images) in different div tags.

TYPO3: category tree of tx-news, render sub-tree only if main is selected

I override Templates/Styles/TWB/Templates/Category/List.html to have the category menu behave exactly as the sidebar menu in the introduction package (submenus show only if main is selected).
If I add the static template "News Styles Twitter Bootstrap (news)" I'm almost there, it is not difficult to open the sub-categories only if the main category is selected (I need a massive amount of categories/sub-categories), but it should also be open when a sub is selected:
...
<f:if condition="{0:category.item.uid,1:category.item.uid} == {0:overwriteDemand.categories,1:category.children.{overwriteDemand.categories}.parent}">
<f:if condition="{category.children}">
<f:render section="categoryTree" arguments="{categories: category.children,overwriteDemand:overwriteDemand,class:''}" />
</f:if>
</f:if>
...
I do not know how to use {overwriteDemand.categories} as key to match the value ... can anybody point to the proper syntax
update: I tried to apply a custom ViewHelper as this post suggests, but using TYPO3 V7.6.16 got stuck with the error should be compatible with TYPO3\CMS\Fluid\Core\ViewHelper\AbstractConditionViewHelper:‌​:render(), so could not try working with the variable overwriteDemand.categories in another way ...
Dynamic access to variables in fluid is just possible since TYPO3 8. Check out the Whats New Slides here: https://typo3.org/download/release-notes/whats-new/ and search for "Dynamic variable name parts" in the PDF.
In TYPO3 7, the "vhs"-Extension provides a ViewHelper to do the same job but nesting a ViewHelper within an complex f:if-condition is even more difficult. If possible, try out TYPO3 8. If it's not possible you may write your own ViewHelper to solve this logical problem.
