SimpleList ClassCastException fix. (2.34 KB, patch)
2005-12-15 10:27 UTC, Bodo-Merle Sandor 		none Details | Review

Description Bodo-Merle Sandor 2005-12-15 10:25:28 UTC 
Steps to reproduce:
1. Just instantiate a SimpleList.
2. 
3. 


Stack trace:


Other information:
Because SimpleList extends Widget seems that calling
TreeView.getTreeView(getHandle()) results in ClassCastException, because
getHandle() returns not the TreeView's handle passed to super but the Handle
associated with SimpleList itself.

A patch that turn SimpleList to use a static factory method follows.

SimpleList ClassCastException fix.

switch SimpleList creation to a static factory method.

Thanks for the report and patch. It turns out that we don't need a new factory method here. Based on your patch, I simply changed the static factory method to be the public constructor and created the TreeView inside a this call. Fixed in CVS HEAD.
