struts - jsp used to set property attribute in <html:errors/> tag

[jb]

I was wondering if anyone has seen something like this before.

It could be a struts issue with jsp.... maybe the property attribute
in the <html:errors /> tag doesn't work with dynamically generated
text?

----------------------------------

I'm trying to print out a message that's saved in an ActionErrors
object.

It DOES work if I hard code it like this.

<html:errors property="partCost0" />

(it prints out "Part cost must be a number" which is
just fine )

and it does NOT work if I use this method.

<html:errors property="partCost<%= row%>" />

( it just has a blank space )

I've done a System.out.println on the value partCost<%= row%> with the
code

<%System.out.println(" partCost"+ row ); %>

and it does print out

partCost0, partCost1, etc, for each row, so that's not a
problem.

NOTE - row is an int.

Does anyone know why the dynamically generated text won't work when the
hardcoded value will, even though the dynamic value is correct?

Hello everyone,

I found the answer to this. In case anyone else needs this, here it
is.

the html errors tag can't parse a property attribute (and maybe other
tags have this issue too) with both a literal and a dynamic element.

It DOES work if you do it this way

<% String partCostString = "partCost"+row;%>

<html:errors property = " partCostString "/>

Have fun.
