problem using the tag

["To, Wilson" <Wi...@umusic.com>]

Hi Struters,

I have a problem using the <logic:equal> tag.  

I have a bean collection (Array List of value/label pairs of String's - used
in an <html:select>) and I'm using the <logic:iterate> tag to iterate over
the collection.  Whilst looping over the collection, I want to test to see
if the value of the collection matches the value of another bean (not a
collection but just a single String value).  If so, it will display the
contents of that collection.

I have coded the jsp as follows:

<logic:iterate id="projectCollection" name="projectsList">
   <logic:equal name="projectCollection" property="value" value='<bean:write
name="projectCode"/>'>
      <bean:write name="projectCollection" property="label"/><br />
   </logic:equal>
</logic:iterate>

However, this DOES NOT APPEAR TO WORK.  If I replace value='<bean:write
name="projectCode"/>' with value="PH" (i.e. a hardcoded value) then it
works.  

Needless to say, if I display the contents of the bean using <bean:write
name="projectCode"/> on it's own, it displays "PH" as expected (without
quotes).

It also seems odd that I tried playing around with declaring variables
within JSP and using that within the <logic:equal> tag as follows but it
also does not give the desired effect:

<% String pcode="PH"; %>
<logic:iterate id="projectCollection" name="projectsList">
   <logic:equal name="projectCollection" property="value" value="<% =pcode
%>">
      <bean:write name="projectCollection" property="label"/><br />
   </logic:equal>
</logic:iterate>

I'm using version 1.0 of Struts and version 3.2.1 of Tomcat.

Can anyone throw any light on this?

You may want to say 

<logic:equal name="projectCollection" property="value"
name="projectCode"/>
