Hello!Im working on a RCP application and in one of my views, I have to display informations in a TreeViewer depending on which editor is activated.So I thought about using a PageBook.But I have a problem: it seems that I have some display issues with the PageBook: each time I activate a new editor, I create a new TreeViewer corresponding to it and I try to display it:

	_pageBook.showPage(_treeViewer.getControl());

For the first tree viewer, it works well, but when I try to display another one, my PageBook displays nothing, or the same TreeViewer has before but with no response to any mouse clickAnd when I come back to the first editor, the tree viewer corresponding to it is still well displayedI dont understand what is happeningSo, basically, it seems to work but only with the first displayed TreeViewer!!Could somebody please help me?Thanks by advance!C.B.

Well, I didn't succed in using the Eclipse API PageBook... :-/
So I did it another way: I use only one TreeViewer and I reload it with the current data when the editor is changed.
I store the expanded elements in a HashMap<String,Object[]> where teh keys are the name of the current project (one tree structure per project) and the values are the expanded elements, and I save everything in a memento when I quit the view...
It seems to be working!

I'm not sure why you would have to do showPage yourself.

If your TreeViewer is the main part of your view, then you might be better off extending PageBookView.

PageBookView takes care of remembering what page of you pagebook goes with what part and calls your various pages depending on what IWorkbenchPart you're interested in.

In addition, if you are to listen to changes or selection changes in the IDocument being processed by the (workbench)-page editors, it's also probably a sounder foundation.

I thought about that, but the problem is that every view (including the one I'm currently interested in) in the applicatiion extend an amount of abstract classes and I would have had to break a little bit the architecture which is not mine, create top interfaces, duplicate a lot of code, and so on...Too bad the Java does not support multiple inheritance for those type of issues :-/...Anyway, the solution I found seems to be working ;-)!
