Hi,
I extend the ProjectExplorer, and maped some file to my elements.
To open that elements, I added an actionProvider in the navigatorContent
extension.
In my actionProvider class I called the
actionBars.setGlobalActionHandler(ICommonActionConstants.OPE N, myAction);
The run() in my action just called the IDE.openEditor() method.
The strange thing is that, for some editors (infact which extends the
EditPart directly) , there can by one instance of that kind of editor,
for example, there is AEditor which is used to open the files like *.a
and BEditor which is used to open the files like *.b.
if i opened an AEditor, the if I double-click on the elements that will
open BEditor, nothing happen.
And, if I add a break-point in the run method, if I double-click, it
always will be arrive to the break-point in the run method.
That is to say, with the break-point, the run method will always be excuted.
but if I remove the break-point, the run method will not excuted(it can
be konw throug the System.out.printl("****")).
But if I right-click on the element B, and select "Open" in the context
menu, It works well.
This had made me crazy, hope that there is some one can help me.

Addtional,
If I opened an AEditor, then if I double-click on some B elements,
nothing will happen.
But I switch to another window, in windows xp, and switch back, and then
double-click on some
B elements, BEditor will open.
This message maybe help.

Dollyn,
It's hard to determine what you problem is without seeing the code,
I had a similar problem recently and I resolved it by overriding the
handleDoubleClick method in my class which extends the CommonNavigator.

Well, I replaced the method IDE.openEditor(page, file); to
IDE.openEditor(page, file, false);
and everyting seams ok now.
In the JavaDoc of this method, the description about the third parameter
is: "If |activate == true| the editor will be activated. "
I'm not sure about the meanning of the "activated" here, because my
editor always "getFocus", although I give it a "false".
