Action Viewer popup selector not working

Overview

Action Viewer presents action selectors and tag research on the top left of its GUI. When the user select a family and then an action (or just an action, or just type a keyword in the tag area) in the corresponding combo box, it should directly trigger the action and show the widget in the bottom area of the Action Viewer widget. This is broken.

Apart from reducing the user experience, this might result in misunderstanding or wrong action from the user.

Steps to Reproduce

Select a family and an action

• Open a component (e.g. cthead1.lsm)
• click on the Family combo box and select a family (e.g. File)
• click on the Action combo box and select an action (e.g. Close)

or select an action

• Open a component (e.g. cthead1.lsm)
• click on the Action combo box and select an action (e.g. Image Look Up Table)

or type a tag

• Open a component (e.g. cthead1.lsm)
• enter a keyword in the Tag text input (e.g. Change)

Actual VS Expected Result

The action should be triggered (e.g. close the file) but noting happen.

Moreover when an action is selected, the family and action combo box do not display the correct values:

• Open a component (e.g. cthead1.lsm)
• Right Click on the component in the explorer
• Click on View → Image Look Up Table
• Click on the Family combo box and select a family (e.g. File)
• The Action combo box is not updated correspondingly

Interpretation & Possible fixes

ActionViewer is the culprit.
