Subject RE: Question about logic:iterator, indexId and hidden fields
Date Thu, 01 Apr 2004 14:29:45 GMT
Thanks for the suggestion, but that doesn't work either.  The
<nested:submit> tag isn't replaced with an <input> tag when I use the syntax
you suggest.  I've tried many variations on these syntaxes.  If the JSP
expression get's parsed, the struts tags aren't understood.  If the struts
tags are understood the JSP expression isn't parsed.

Any other ideas?  Surely this is a common usage pattern.

The problem is that you have illegal JSP syntax for the 'onclick' attribute.
The attribute value must be a string literal or a scripting expression. You
cannot mix the two. Try this instead:

  onclick='<%= "setEditIndex(" + index + ")" %>'
