I tried the above, i.e., specifying null icon, with ULC 6.1.1 and JRE
1.4.2_05. I am not getting any errors.
I tried putting a particular leaf icon and that is displayed correctly.
When I specify a custom renderer, no icon is displayed for leaf.
When I do not specify a custom renderer then:
If icon is specified in uidefaults, then that icon is displayed
If icon is null in uidefaults, then default icon is displayed
At no time I got an error.
Am I missing something?
You say that you have a customized L&F class. Which L&F do you set?
It will help if you can send a small snippet with all the relevant classes.
Thanks and regards,
Janak
