Not sure about the exception, but as of 1.1, you can write your loop like this:
<logic:iterate name="problemArray" id="currentProb" scope="request"> <bean:write name="currentProb" property="problemName"/> <html:radio property="problem" idName="currentProb" value="name"/> </logic:iterate> See: http://jakarta.apache.org/struts/userGuide/struts-html.html#radio Also a clarification that the "property" attribute of the <html:radio> tag does *not* need to be linked to the form bean. That's just the default. You can also provide a "name" attribute to link to another bean. Quoting Jeremy Cavagnolo <[EMAIL PROTECTED]>: > Charlene: > > Thanks for the input. However, it didn't work.
