Hi,
I am using a ULCTableTree. The problem is that the structure-changed
event from a model causes the table tree to remove its contents, but it
does not load it back again!
I am attaching a sample application demonstrating the problem.
Environment:
- ULC Version: 6.1.1
- Java: 1.4.2 on both client and server.
To reproduce the problem:
1. Please run the following application and double-click the table tree.
2. The content of the table tree vanishes!
Am I doing something wrong or is it a bug with a work around?
Thanks and Regards
Indukumar
