Hi All,
I am getting the following exception when trying to get Tree View example
working. I have created an Eclipse project for this and trying to run it via
Eclipse. I haven't made any modifications to the sources except for the icon
paths in tree_data.wtkx which I think may be the source of the trouble.
An error occurred while processing element <TreeNode> starting at line
number 4 in file
/home/chamith/Development/Eclipse/General/Memo/bin/tests/tree_data.wtkx:
java.lang.IllegalArgumentException: iconURL is null.

..................
Some of the lines in the tree-data.wtkx refering to icons are as follows
with relative paths. Icons are located in the same folder as class files and
wtkx files.
<TreeBranch text="Activity" icon="folder.jpg">
<TreeBranch text="Games" icon="folder.jpg">
<TreeNode text="Foosball" icon="page_white.jpg"/>
<TreeNode text="Ping Pong" icon="page_white.jpg"/>
<TreeNode text="Air Hockey" icon="page_white.jpg"/>
Any help is greatly appreciated.
Regards,
Buddhika
