what's the exceptin means? 

I tested a sample code, it's works fine, I can not give you a sample to reproduce the exception.

It seems a thread issue with my code, how to fix this? the app works fine with dwt-win, dmd 1.037 and dsss(lib), now I built dwt2.lib by dsss, get the sampe exception.

I ported my code to dwt2, I spend twot days to tried to figured the thread issue out, but failed.

thanks!



My code like this:

auto menuManager = new MenuManager("#PopUp");
menuManager.setRemoveAllWhenShown(true);
menuManager.addMenuListener(new MyMenuListener);
    
auto menu = menuManager.createContextMenu( treeViewer.getTree() );
treeViewer.getTree.setMenu( menu );

class MyMenuListener : IMenuListener {    
    void menuAboutToShow(IMenuManager manager) {
        fillContextMenu(manager);
    }
}

public class TestAction : Action {    
    public this() {
        super( "test", null);
    }
    void run() {}
}


void fillContextMenu(IMenuManager manager) {
    manager.add( new TestAction );
}
