RE: Iterate and onClick problem for html:submit

[Ben Anderson]

This is because you can't mix the value of an attribute of a custom tag with 
both string literal and run time expressions.
Instead of this:
<html:submit onclick="this.form.hiddenId.value='<%=(String) theCode %>'; " 
value="Edit" />
something like this should work:
<c_rt:set var="theCode" value="<%=(String) theCode %>"/>
<c:set var="theCode" value="this.form.hiddenId.value=${theCode}"/>
<htm-ell:submit onclick="${theCode}" value="Edit" />
however, based on your use case I would suggest making use of the property 
attribute of <html:submit.  This way, a value will automically be submitted 
with the form based on which button you select.

Hi,

I have a problem at the moment where I wish to set a hidden field on a form 
depending on which button a users selects.  So my JSP loads with N number 
of possible rows in a table.  Each row has a button (Edit) associated with 
it.  When the user hits the Submit button I want a hidden field to be set 
so my Action class can read it from the form and act appropriately.  The 
problem is that after defining my bean I cannot evaluate the property - the 
parameter I retrieve in my Action class is set to <%= (String) theCode %> 
and not the value I require!

Here is an extract of the code:

<logic:iterate id="item" scope="session" indexId="index" 
collection='<%=session.getAttribute("theList")%>'>
<tr>
<TD class="body_text"><bean:write name="item" property="section"/>
<bean:define id="theCode" name="item" property="title"></bean:define>
<html:submit onclick="this.form.hiddenId.value='<%=(String) theCode %>'; " 
value="Edit" />
</TD>
</TR>
</logic:iterate>

The problem is compounded by the fact that the page works using standard 
html as follows:

<input type=button onclick="this.form.hiddenId.value='<%= (String) theCode 
%>'; value="Edit" />

but I need to use Struts Html if my DynaValidatorActionForm is to work (I 
think!).

I have looked through the archives and although I have found people having 
similar problems I cannot get a solution.  I have also tried all 
combinations of quotes and escaping quotes etc with no success.

I'd appreciate any help people could give.

Regards,
Simon.
