Jhipster React Form Grid Layout Issue

I'm currently using the latest version of Jhipster 7.6.0 and Node 16.14.0. If we try to arrange form fields in column view in other words if we wrap ValidatedField to and , the field values are not populated during Edit mode of the page and the same is true for insert mode. The attached link is showing a simple layout change on the existing user management page, and we are trying to see Last Name and First Name in one row, and we are unable to see the value or update the value if we realign these fields in multiple columns views.
Does anyone know a simple workaround we can use ValidatedForm and ValidatedField in Row, Col, and regular CRUD works like with other pages generated by the framework? Please let me know if more clarification or detail is needed on this case.
Layout and code Sample from User Management page

using itextsharp add image under text but over other images that have been placed

Imagine a pdf with text and a application that test images over the text.
In every test pdf is saved and the next test using same pdf.
The first time you add image under text you can see the results, next time you will try you add image under is not appear because first image cover it.
So...exists something GetBetween or can i choose the layer that i want?
If i use GetUnderContent only first image appears and all others are hide.
If i use GetOverContent then the text is covered by image.

Magento 2, new widget with image chooser parameter, does not save picture

I am new on magento2.
I create a new widget and one of the parameters is a picture chooser, I just use this https://gist.github.com/cedricblondeau/6174911fb4bba6cb4943 code. Everthing looks well. I can open media folder and choose the picture I want to use.
When I choose the picture, the picture field on the form, is filled with this value: http://local.magento.com/admin/cms/wysiwyg/directive/___directive/e3ttZWRpYSB1cmw9Ind5c2l3eWcvcHVycGxlLmpwZyJ9fQ,,/key/4c150d984998702b74709bb8f05820aff2f85a968d47e50f9638b7d2a7b1ced3/
But when I save the form widget data, the picture fied has this value:
{{media url=
nothing more. How can I solve this?

Android - Drawer navigation adapter

I am implementing a navigation Drawer as per: http://developer.android.com/training/implementing-navigation/nav-drawer.html
The tutorial only shows a single TextView with ID android:id="#android:id/text1" and this is populated for the ListView using:
mDrawerList.setAdapter(new ArrayAdapter<String>(
this,
R.layout.drawer_list_item,
mDrawerItems));
Now, I want to include an ImageView inside each ListView item. This will represent the Icon for each item.
Question: Inside my xml for the list items (where the TextView text1 is located), I have included an ImageView.
What do I need to name the ID for the ImageView?
And then, do I simply add the drawable-array reference to the setAdapter like this?
mDrawerList.setAdapter(new ArrayAdapter<String>(
this,
R.layout.drawer_list_item,
mDrawerItems,
mDrawerIcons));
Thank you
I found out that creating an ArrayAdapter in the format above does not allow you to input more than one set of data to the Adapter. For instance, I can only use my list of Drawer Navigation names contained in the Array<String>: mDrawerItems. To pass Icons and other data to the adapter, I have two option:
Simple Adapter used with a Map, or
Custom Adapter.
Examples of both can be found here: http://www.vogella.com/articles/AndroidListView/article.html, and here:
