Thanks -- your option (2) seems to be working fairly well for me now.  I =
still have to see if struts will accept the faked up input tag and stick =
the data into the form bean, but I don't see any reason why that =
shouldn't work.

I wonder why (1) wouldn't work for me though -- it gave me the same =
result as the JSTL tag did. (It iterated fine but would just print out =
${cur.prdNumber} rather than the actual vaule)

It seems odd that the EL tag does everything except actually do the =
EL-evaulation.

i can think of 2 things you can try:


1) use <logic:iterate> instead of <c:forEach>

i have found that jstl-scoped objects do not always work well with
struts tags


2) simply don't use the <html-el:text> tag

you can achieve the same result with:

<input type=3D"text" name=3D"quantity(<c:out =
value=3D'${cur.PrdNumber}'/>)"
maxlength=3D"5" size=3D"3" value=3D"">
