Hi,

I'm using Struts 1

I have  a set of indexed error properties :

myProprty0
myPorperty1
myProperty2

and so on

I'd like to be able to pass the relevant name in to <html:errors property
via a variable – for example:

<c:set var="total" value="${0}"/

iterate...

<c:set var="myErrProp" value="$myProprty{total}" />

<html:errors property="<c:out value="${myErrProp" /><br/>

<c:set var="total" value="${total + 1}"/>

</iterate>

Is there a way to do this?

Thanks in advance,

Charles

Oh, well that's a lot simpler than what I was thinking if it works :-)

Mmm.. let me see:
<c:forEach var="index" begin="0" end="5">
  <html:errors property="myProperty${index}" />
</c:forEach>

Not really; it *might* be possible to do some funky EL manipulation like:

   <c:set var="prop" value="myProperty${total}" />
   <html:errors property="${myform[prop]}" />

although it may take a bit of fiddling to find the right combination of 
syntax. But really, you'd be better off using an array or list -- i.e. a 
'real' indexed property, instead of pseudo-indexed properties using a 
naming convention.
