ChoiceView and strange Visualizer problem

[Jean-Marc Borer]

Hi all,

I just wanted to try different view types for data nodes. I used the
sample from Selection tutorial that you can find
http://plugins.netbeans.org/PluginPortal/faces/PluginDetailPage.jsp?pluginid=3146

Then in "MyEditor" I replaced, new BeanTreeView by ChoiceView, making
sure that it is no longer a JScrollPane but a JCombobox. When I run
the application I get this strange error:

java.lang.ClassCastException: java.lang.String cannot be cast to

Looking at the sources of NodeRenderer there is this very strange line:

VisualizerNode vis = (value instanceof Node) ?
VisualizerNode.getVisualizer(null, (Node) value)
: (VisualizerNode) value;

where the value seems to be a String. Isn't this an error? Why cast to
VisualizerNode when the value isn't a Visualizer???

I am using Netbeans 6.7.1. Any one running into this issue? I am
missing something?

Cheers

Jean-Marc

I found the solution. Drop a JCombobox into your panel, then in the
properties clear the field "model" for the combo. The editor won't create a
new "inline" model. So you can continue to create you interfaces visually
and use NB views. Very handy
