iterate header/footer

Title: iterate header/footer





The main issue I have with the logic:iterator tag is the lack of support for iteration headers/footers. Is there some sort of support for this currently that I've missed? I'm talking about this:

logic:iterate ... id=bean
 logic:header
  table
  trthName/th/tr
 /logic:header
 trtdbean:write name=bean property=name//td/tr
 logic:footer
  /table
 /logic:footer
/logic:iterate


This would prevent any HTML from being generated if the collection is empty.


I tried using the greaterThan tag but it does not support the Collection.size() property (since it's not a proper bean property name). Any suggestions as to how best to put this into Struts? Is the header/footer tag a good or bad idea and why?

Mike,

You should use the logic:present ... 
Tag. For example:
logic:present 
name="org.apache.struts.action.ERROR"...table 
header...
/logic:present

See the mail archives for more info.
