[neon] AbstractOutlineViewButton behaving differently from Mars [message #1751350]

In our application we have several outlines in various DesktopExtensions. Their accesibility to users depends on the users' permissions.

In Mars we solved this by overriding the initConfig() method of the corresponding AbstractOutlineViewButton. If the user didn't have the required permissions, we called setVisible(false) and setVisibleGranted(false) which caused the button to not be shown on the GUI.

However, in Neon, these OutlineViewButtons are always shown, even though their visibility has been set to false.

Is this a bug? Or do we need to change our setup to make this work?

I think you should override execInitAction() instead of initConfig(). In AbstractOutlineViewButton.execInitAction(), setVisible[Granted]() is called with the corresponding outline's values, so this method overrides your previously set values.

public abstract class AbstractOutlineViewButton extends AbstractViewButton implements IOutlineViewButton {
   ...
  @Override
  protected void execInitAction() {
    setVisibleGranted(m_outline.isVisibleGranted());
    setVisible(m_outline.isVisible());
    setEnabled(m_outline.isEnabled());
    ...

It should be sufficient for your case to set the "visible granted" property. The "visible" property is intended for business logic, while the "visible granted" is intended for permissions. An object is only available if all flags are true. (But be aware, that an object with "visible granted = false" can never be visible again, as the object is not sent to the UI at all.)

Beat
