Title: iterate header/footer
|
I'm
not sure I understand:
the
"bean" object does not live outside the scope of the iterate tag so the present
tag can't go there.
Inside
the iterate tag, the present tag would evaluate once per iterate loop and print
the header multiple times - which defeats the purpose.
Can
you give me a working example of what you mean? Am I misunderstanding
something?
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.

Subject: 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>
<tr><th>Name</th></tr>
</logic:header>
<tr><td><bean: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
