I'm new to ZK framework and trying to implement a simple thing but ZK's different approach is boggling my mind:
I have a grid with a model as a Person list. All grid fields are editable textboxes and are populated with Person's name and surname (2 columns). What I'm trying to do is:
-- Implement a "Save All" button, which will bind all changed values to respecting Person's name and surname properties.
Simply, on "Save All" click, save all changed values. But I don't want to change anything before button click, so there will be no #save on textboxes, just #load.
What I did so far:
-- On textboxes' onChange event, save textbox's value on a temporary Person object's property (either name or surname), and add that Person to a changedPersonsList. On SaveAll button's click, replace my model's Persons with changedPersonsList Persons... But then I can't know which Person is which without implementing an ID field.
Everything would be SOO easy if I just can send label values on SaveAll click along with row number.
You can control the timing of data binding with condition keywords..
<textbox value="#load(vm.text) #save(vm.text, before='saveAll')"/>
<button onClick="#command('saveAll')"/>
Here we use the before condition to coordinate when the value should be saved: not when it is changing (like normal) but when the saveAll command is about to be executed.
You can read more about this in the ZK documentation.

I want a button from the command line bar to be visible or invisible depending on whether a record has been selected in the lookup field from the main form or not.
If no record has been selected, then the button should be displayed. Otherwise not.
For this problem, I want to use the Power Fx in PowerApps, but I haven't found a command yet, which shows me the content or something like that of the lookup field. Other field data types like text have worked without problems.
With Javascript, I already managed it without problems, but I would like to do it also in PowerFx if that should work.

The records come from the Table Company, where the attribute is Companyname.
Commands where I think they might work:
If([Selected Record];true;false);If(IsBlank([Selected Record]);true;false);If(IsBlankOrError([Selected Record]);true;false);If(IsEmpty([Selected Record]);true;false)
I guess there are 2 scenarios:
The Lookup form control element is a Dropdown with a Selected output property. Then your approach would work like If(IsBlankOrError(DataCardValue1.Selected),true,false)
If your form control element is a ComboBox then you could use If(CountRows(DataCardValue1.SelectedItems)>0,true,false) or the above described IsBlankOrError.
Is there a way to populate a List property on an object being tested under the "new style" test scenario?
I see some "legacy" test cases which seem to achieve this so am wondering if the new style test scenario handles this.
I added the List model to my test case, which enabled me to expand the sub-property on the object, however there is only one field available there, "empty" (boolean). Is there a way to add an object here? If it makes any difference, the model is an external java dependency.
Update
The reason I wasn't able to add the List of objects was because I didn't explicitly import that object dependency into the test. Once you import it you can follow the steps given in the answer below.
It's definitely possible to manage a List property under the Test Scenario Editor.
Please consider the following example: A Book class with a List<String> property named topics.
Creating a new Test Scenario assets, please select the column where you need to add the List property, and in the right part of the editor select the property expanding the Book class, as shown below:
Pressing Insert Data Ojbect button will assign the selected List property to the selected column:
To fill the data in the List property, please double click on the Insert value cell, in the first scenario data row. A popup will appear. Its aim is to fill data inside a collection
To add a value, please press the Add list value link in the bottom part of the popup. Here, you'll be able to fill a single item on the list
Repeat this step for all the items you need to add to the list. When completed, simply press to Save button
The popup will close and you should see the previously selected data cell filled with a label similar to List(2), the number represents the number of the items in the list.
I'm looking for a good way to reveal a hidden element (a div) based on specific input into a form field. The application is an order form that isn't using any database. I want to have users input a coupon code and if it matches have the div appear (which contains what is needed to do the discount). And if it doesn't match it either does nothing, loads another hidden element or reveals a message like "invalid code".
PHP would be preferred but I'm open to anything. I don't see how the textbox where users enter the code has to be submitted with a submit button as it would submit the order form. It isn't critical that the discount is 100% secret. In other words, if they think to view the source code to see if they can figure out if there's a discount then they've earned it.
I've thought about using a inline frame for simplicity but I don't think that will work.
You could use the input's oninput function to watch the value entered. On each keypress you could make a call to see if it matches a coupon code. If the coupon codes are always "x" length, you could only do the call when the value reaches that length (if you don't want to call on every single keypress).
Alternatively, you could use a button and use it's onclick attribute. It would be the same idea as above, just instead of making the call on every keypress, you would only make the call on the button's click.
Once the value matches, just set the hidden div from "display: none" to "display: block" or something like that.

my SAPUI5 app has an input field where the valid values must be obtained through a value help:
<Input showValueHelp="true" valueHelpOnly="true"
valueHelpRequest="onValueHelpRequest"
value="{myModel>/myField}"
The value help is realized with a SelectDialog, where the only options are
choose one or
cancel
The problem is now the following flow:
User opens value help dialog to choose one item and presses Confirm
Input field now displays chosen value
User wants to clear the input, because it's optional
Unfortunately,
sap.m.Input doesn't provide a clear button
sap.m.SelectDialog doesn't provide the possibility to add a custom button like Clear
The input is layed out in a SimpleForm with 2 columns, labels and input fields, so it would be hard to add a clear button
The Gateway entity set which feeds the value help dialog list doesn't have a totally empty line
I don't like the workaround to switch the SelectDialog to multiSelect just for the purpose that the user can choose "one or none". I also think it would be hard to explain to the user "if you want to remove the value, hold the control key and click on the previously selected item again".
Any ideas out there how to easily implement a clear button or something similar?
valueHelpOnly="false"
// with this user can either fill by F4 (assisted input) or by typing input..
and if you want to clear you can add a button and set the value to null
oInput.setValue("");
I have a dataPointGrid and I want to check if a record from it is being selected (mouse clicked on)
Data point grid above. I want to check if a folder (record) is being selected.
Is there a method that does this?
Add ListGrid#addSelectionChangedHandler() on list grid that is called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).
Look at the ListGrid#setSelectionType() as well that defines a listGrid's clickable-selection behavior (MULTIPLE, SINGLE, SIMPLE or NONE)
