Subject: (Newbie Question) How to use java code as attributes in struts
tags


I searched the archives but couldn't find anything on this.

When I try to use java code or jsp tags as the value of an attribute
in a Struts tag element, I get a compilation error.

The specific example is:


  length=<%=causeCodeTable.getMaxDisplayValue()%>
  id="causeCodeRecord"
  type="com. ... .CauseCodeData"
  indexId="index">

I'm tying to display a subset of an array of objects starting at "offset"
and up to "length" entries. If I hardcode the values of offset and
length, it works exactly as I'd expect.

Any suggestions? Thanks in advance.

another thing you might consider doing is using  tag before
the iterate to define the counts and then go use the variable in the
iteration tag.

This looks cleaner and there are not too many pesky <% %> hanging around the
code.

The <%= %> also has to be put into quotes.  That is what he means by
"properly quoting your attribute values".  I got caught on that one way
back when too.  Good luck!  Keep hacking.  Soon this will be second nature.

If you get an exception, and you don't show us anything about the
exception or much of your code or configuration, you're not likely going
to get very useful help.

Nevertheless, you might try properly quoting your attribute values.
