update folder of tree after leaf removing

[msimun]

Hello,

I'm using smartGWT 3.0 version and have following problem:

I have TreeGrid that is bind with datasource recieveing data from server:

TreeGrid projectTree = new TreeGrid();
final Tree tree = new Tree();
tree.setModelType(TreeModelType.PARENT);
tree.setNameProperty(CampaignProjectDescriptor.NAME);
tree.setIdField(CampaignProjectDescriptor.ID);
tree.setParentIdField(CampaignProjectDescriptor.PARENT + "." + CampaignProjectDescriptor.ID);
tree.setDefaultIsFolder(false);
projectTree.setDataProperties(tree);

when I delete some node of that tree in other smartGWT widget, it's automatically removed also from tree, that's very good, problem occurs when I delete node that has some parent and that parent has only 1 child - then leaf is removed from tree but former parent node has still parent icon even it has no child.
When I refresh tree it's rendered correctly

Could you please advice me how to achieve automatic changing parent node type after children removing?

thanks,

michal

A parent that loses all it's children is not the same thing as a leaf, so this is expected.

To convert it to a leaf you would need to remove the folder and add a leaf as a replacement.
