Does anyone know of a simple way to send a logic:iterate's indexId back as a

I mean when the page is compiled, the <nested:submit> tag is converted to an
<input> tag before the <%=index%> tag produces Java code.
I think the taglib directive *is* incorrect whenever I get the <%=index%>
tag to produce Java code, that's why it leaves <nested:submit> in the HTML
output. When I remove the <%=index%> tag, or when I include it in such a
way that it doesn't generate Java code, the <nested:submit> tag is
recognized.
What I want to do is write a <nested:submit> tag that passes the value of Integer "index" to a Javascript function in its "onClick" function.

I think we're having trouble understanding what you're doing. In particular, you say that "the <nested:submit> tag is evaluated before the <%=index%> tag". What do you mean by that? Then, you are now saying that after fixing your scriptlet expression reference, you say that the "<nested:submit> tag isn't replaced with an <input> tag". Do you mean that in the HTML output, you see "<nested:submit ..>" instead of "<input ...>"? If you're really seeing "<nested:submit ...>" in the HTML output, then this would indicate that your taglib directive is incorrect or not present.

Subject: RE: Question about logic:iterator, indexId and hidden fields
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.

I have a form with a list of elements on it. Each element
has an "Edit"
button associated with it. When the user clicks the Edit
button for a
specific element, I want to send back the value of indexId
in a hidden field
on the form. I can't figure out a clean way to do this. The
documentation
says "indexId" will create a bean, but it really creates an
Integer (which
isn't a JavaBean). I've tried passing my indexId to a
Javascript function
that sets the form's hidden field sort of like this:
<nested:submit propert="edit" value="Edit" onclick="setEditIndex(<%=index%>)"/>
but the <nested:submit> tag is evaluated before the <%=index%> tag
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 + ")" %>'
-- Martin Cooper
Right now I've got some ugly JSP code that outputs the
submit element that
calls the Javascript function that sets the hidden field.
There must be a
simpler way. Any ideas?
