Hans,
I should have put more info in my previous mail...
I do have
<attribute>
<name>inNum</name>
<required> true </required>
<rtexprvalue>true</rtexprvalue>
</attribute>
defined in the tld file.
I also tried the following
<tlt:twa
attr1='java.lang.Integer.valueOf(response.getParameter("num")).intValue()'
type="int" />
-Chandan.
