Tree Table : links are not shown

Question

I've created a custom Table structure by combining a JTree and JTable.

it looks like this:

addition of leafs can be done to any element.

But when I try to add a node to a row which has children already, the link in not shown and the newly added row is also not shown.

this is how it looks when a new row is added to "Package":

But this problem does not occurred when a node is appended to a leaf.

But there are no errors or exceptions thrown.

after a node is added i do the following:

fireTableDataChanged
fireTableStructureChanged
scrollPathToVisible

although these are called the problem remains.

can anyone please give a suggestion?

thanks in advance...

Try calling updateUI() on the JTable or JTree. updateUI() will propagate, rendering the rest of the components beneath it.
