Changing parent of a node in the tree table [message #1110106]

Hi,

I have populated my Tree Table, with some nodes.
Before adding these nodes to the table, I assign them their parent (if any), then add them to the Table.(event list actually).

For example:

Node node = new Node();
node.setParent(parentNode);

eventList.add(node);

Something like that!

Anyways, what I need to do is that when I change its parent to some other node, it should be a child of some other node and reflected in the Tree Table.
But it stays the child of the same node.

For example:

Before

-Parent1:
--Child1
--Child2

Child2 is child of Parent1.

After I make Child2 a child of Child1, the result stays the same:

-Parent1:
--Child1
--Child2

Instead of:

-Parent1:
--Child1
---Child2

Is this some restriction in the table, or am I doing something wrong?

Regards,
Ali Ahmad Malik

Haven't worked on such cases. Are you sure the TreeList reflects your modifications correctly? And if so, do you perform a refresh after your modifications?

I did refresh the NatTable after doing that, but no use.

I am not sure where does the problem lie, after changing the parent I also tried:

        sortedList = new SortedList<IDSTreeTableNode>(eventList, null);
        
        treeList = new TreeList<IDSTreeTableNode>(sortedList,
        		treeTableFormat, expansionModel);

        treeData = new DSTreeTableData(treeList);

        treeRowModel = new GlazedListTreeRowModel<IDSTreeTableNode>(treeData);

This should have changed the TreeList, too. I will try and debug for the TreeList now.

Any suggestions?
