Subject Re: [Tomahawk] non-unique IDs in <t:tree2 />
Date Wed, 06 Feb 2008 16:07:18 GMT
That doesn't make much sense to me as generated IDs are in the form of
"_id##", so t2c is not possible unless you or some code explicitly sets it
somewhere. What JSF impl version are you using.

Also try grepping your code for t2c.
