Hi,

I'm trying to provide dialog using:

org.eclipse.ui.dialogs.CheckedTreeSelectionDialog

whereby the user can select elements from a tree. Th selection aspect
works fine, however I'm having problems setting the initial state of the
tree when the user returns to the dialog. I have a list of previously
checked elements, taken using:

CheckboxTreeViewer cbtv = this.getTreeViewer();
Object[] allFilters = cbtv.getCheckedElements();

However when I try and reconfigure the tree with this selection, it
doesn't seem to work:

((CheckboxTreeViewer)this.getTreeViewer()).setCheckedElement s(allFilters);

No errors, no nothing.

Any help with this frustrating problem, much appreciated.

James

Just to add, the method below does work for the root item of the tree.
But not for any of the sub branches.
