Retrieving of selection [message #759431]

Hi guys,

I have a small question about selection providing. Currently I've faced with following problem:

I have an editor with information about some entity within (let's assume that this is some products for mobile phone number). And I have view which should display short information for this phone number (let's assume that this info is phone number, status and owner). So, as I understand, editor is a provider of selection for view and view is a listener of selection from editor.
I've implemented simple ISelectionListener in my view, which was registered to view site ("getSite().getWorkbenchWindow().getSelectionService().addPostSelectionListener(listener);") and it seems that view recognize selection when I select editor. But what's the problem? When I've tried to use HandlerUtil in menu handler I've got null instead of my selected entity. It seems that I do something in wrong way, but I can't understand. I tried to provide selection from view - in this case HandlerUtil returns what i need. But From my point of view my view part is only listener, but not provider of selection... Or view anyway should provide selection even if it's not a provider by logic.

Any advices will be helpful.

Hi,

do you mean HandlerUtil.getActiveSelection()? It returns the selection provided by the active part AFAIK. So check what part is active when you select the menu item.
