Description _ lcincura 2004-08-31 15:09:09 UTC 
NetBeans IDE 200408271257 on java 1.5.0-rc-b63

1, Create many watches
2, Select some watch and press Ctrl+A (select all)
=> this operation is very very slow. From user
point of view it looks like IDE is frozen.
Comment 1 _ lcincura 2004-08-31 15:11:21 UTC 
Reproducible also on other debugger views
Comment 2 Jan Jancura 2004-08-31 16:58:48 UTC 
Looks like very ugly bug in TreeTable:
TreeTable$ListToTreeSelectionModelWrapper.updateSelectedPathsFromSelectedRows

Ctrl+A (select all nodes) for 1000 Nodes in one view is translated to
1000 calls of ExplorerManager.setSelectedNodes () method.

Comment 4 _ tboudreau 2004-09-01 11:25:32 UTC 
Fixed - there was no need to singly add paths to the selection model, JTree has 
setSelectedRows(int[]).

Checking in TreeTable.java;
/cvs/openide/src/org/openide/explorer/view/TreeTable.java,v  <--  TreeTable.java
new revision: 1.61; previous revision: 1.60
done
