Counting ActionErrors from JSP

[Philihp Busby <ph...@gmail.com>]

Hi Struts List,

Is there a way through Struts and JSTL Tags to get a "count" of the
number of ActionMessages or ActionErrors?

I would like my <html:messages> to display messages in a numbered
bulleted list when there are more than one, but just display the one
outside of a list when there is only one.

Thanks,
Philihp

Hi,
The "indexId" attribute in <logic:iterate> tag may be useful. For more
information on this, please refer to,
http://struts.apache.org/struts-action/struts-taglib/tlddoc/logic/iterate.html

Thanks,
Tarun.

Philihp,

If you want to get accesses to the ActionErrors class "size()" method from a 
JSP thru lets say JSTL.  You will can extend the ActionErrors and makes the 
method "getSize()".  The access the ActionErrors class in the page my its 
name (see http://struts.apache.org/struts-doc-1.2.x/api/index.html for name 
details).  Anyways I don't know it this is a possible solution to you.  So 
you might try the following scriptlet.

<%
  int count =
     ((ActionErrors) 
pageContext.findAttribute(org.apache.struts.Globals.ERROR_KEY)).size();
%>

Let the list know if any of this helped.

Hi Struts List,

Is there a way through Struts and JSTL Tags to get a "count" of the
number of ActionMessages or ActionErrors?

I would like my <html:messages> to display messages in a numbered
bulleted list when there are more than one, but just display the one
outside of a list when there is only one.

Thanks,
