Hi Guys,

Has anything changed with freemarker templates?

[dan.j.allen]

This is definitely a bug. And yes, the freemarker templates changed significantly. They work with our test case, but clearly not with the Open 18 schema. I will work on getting this fixed.

[dan.j.allen]

Ah! I made a typo. I accidentally wrote indentifier rather than identifier. Please see JBSEAM-3617 for a patch. This problem is resolved for the Seam 2.1.1.CR1 release.

[vimalkansal]

Yup, that fixed the problem. Thanks a lot.
