Gallery : NullPointerException at clearAll() [message #48635] Tue, 05 February 2008 08:37 Go to next message

Originally posted by: tkotisis.urbantech.gr

Using the GalleryTreeViewer, trying to call setInput(Object) with a new =
=

Object, throws a NullPointerException.

The critical part is the following :

public void clearAll() {
checkWidget();
if (items !=3D null) {
// Clear items
for (int i =3D 0; i < items.length; i++) {

// Dispose items if not virtual
if (!virtual) {
if (items[i] !=3D null) {
// TODO: send a dispose event
items[i].dispose();
}
}

// Empty item
items[i] =3D null;
}
}

// Free array if not virtual
if (!virtual) {
items =3D null;
}
// TODO: I'm clearing selection here
// but we have to check that Table has the same behavior
this._deselectAll();

updateStructuralValues(false);
updateScrollBarsProperties();
redraw();

}

items[i] is disposed, and is then assigned to null, which throws the =

Exception.

Could you please post this to Bugzilla? It will be easier to track
there. Thanks.

FYI, GalleryTreeViewer is still somewhat experimental and has only been
tested for my use cases. In particular, it has not been used
extensively on any OS besides Windows XP. If you submit bugs you
encounter to Bugzilla, I'll do my best to keep up with them.

I've fixed this, I still have to check a few things before committing
the changes. Expect this to be fixed for the next week.
The problem lies in the GalleryWidget. This bug was introduced by fixing
bug 193139.

I'll add that I also test the GalleryTreeViewer on OSX, where it works
great. And the Gallery widget is at least used in
http://sourceforge.net/projects/sharemedia and in my gallery navigator
plugin for eclipse http://nricheton.homeip.net/?p=172
