Troubles with Tree View Example

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.

An error occurred while processing  element <wtkx:include> starting at line

..................

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

Thanks. It solved the issue.

Try prepending an @ symbol to the file names. This character tells the WTKX serializer to treat the attribute value as a URL relative to the WTKX file. Otherwise, it is treated as a resource path and the serializer tries to load it from the classpath.
