Manipulate Lists in Properties View

[nedzer0]

Hello everyone,

I defined a Group in Properties View with an attribute (named keys) that is a List of Strings. I wanted to update this attribute with a Dialog or a Wizard like XMI files, where it pops up the wizard that you add or remove a String to that property/attribute (as shown in the picture).
How can I achieve this in Sirius Properties View?

This is my Properties View (I have 2 keys in that group for experiments only, it should only be one with this wizard):

      <groups name="RestoreCache" labelExpression="Properties" domainClass="circleCI_metamodel::RestoreCache" semanticCandidateExpression="var:self">
        <controls xsi:type="properties:TextDescription" name="KeyText" labelExpression="key" helpExpression="Single cache key to restore" valueExpression="feature:key">
          <initialOperation>
            <firstModelOperations xsi:type="tool_1:ChangeContext" browseExpression="var:self">
              <subModelOperations xsi:type="tool_1:SetValue" featureName="key" valueExpression="var:newValue"/>
            </firstModelOperations>
          </initialOperation>
        </controls>
        <controls xsi:type="properties:TextDescription" name="NameText" labelExpression="name" helpExpression="List of cache keys to lookup for a cache to restore. Only first existing key will be restored." valueExpression="feature:name">

            </firstModelOperations>

        </controls>

Hi,

I'm not sure about what you actually get, and what you want to do. From what I understand, you have an attribute that contains a list of Strings, and you want to be able to modify this attribute in order to add/remove Strings, and modify their order. To my mind, the Reference widget that already exists in Sirius and EEF corresponds to this. You could use it and it would cover your need directly in the Properties view, without going through a dialog. See related documentation here.
You can also define an advanced custom widget, which you can use in your Viewpoint Specification Model (odesign). This widget would allow you to edit the string list with a button, and display the dialog. I wouldn't necessarily recommend this, as it can quickly become complex, especially if you're not familiar with the EMF framework. See related documentation here
