JTextPane sizing badly when used as TableCellRenderer

Question

I am trying to display HTML text is a JTable.
I have created a TableModel holding HTMLDocument instances. I set the JTables cell renderer so that it returns an instance of JTextPane with the document
set to the HTMLDocument from the model.That works OK.
Problem is that initially the JTable only shows the first line of html in the JTextPane (it seems to ignore the height from the JTextPanes preferredSize ).
Sometimes if I minimise the Window or click the mouse
on the Table it redraws itself correctly !!!!
Anyone seen similar behaviour ???
TIA

I haven't seen the problem, but it sounds like it has to do with the rubber-stamp behavior of the renderer. If you haven't looked at the Implementation Note on DefaultTreeCellRenderer, you might want to check it out: http://java.sun.com/j2se/1.3/docs/api/javax/swing/table/DefaultTableCellRenderer.html.
You might do well to make your renderer extend DefaultCellRenderer in order to get the useful behaviors it produces. You could add a JTextPane to it, and override the setValue method with one that sets the document for the textpane and resets the preferredSize.
Good luck,
