[e4-dev] enabledWhen ?

[Thomas Kratz <eiswind@xxxxxxxxxxxxxx>]

Hi all and a merry christmas to you.
Let's see if someone is online today :)

I have some handlers that do an instanceof check. I found that this
doesn't work at my side, do I need another addOn or something to make
this work ?
The addOns I currently have configured are as follows

I guess this should be working straightforward ...

<addons xmi:id="_XGB3wPZlEd-XstlTZ6nTXg"
elementId="org.eclipse.e4.core.commands.service"
contributionURI="platform:/plugin/org.eclipse.e4.core.commands/org.eclipse.e4.core.commands.CommandServiceAddon"/>
  <addons xmi:id="_XGB3wPZlEd-XstlTZ6nTXh"
elementId="org.eclipse.e4.ui.contexts.service"
contributionURI="platform:/plugin/org.eclipse.e4.ui.services/org.eclipse.e4.ui.services.ContextServiceAddon"/>
  <addons xmi:id="_XGB3wPZlEd-XstlTZ6nTXi"
