RE: Hashtable and iterate tag

Hi Ella,
you must always specify the type: java.util.Map.Entry , when iterasting over
a hashtable, because this Instance has getter methods "getKey" and
"getValue" which are then specified by the property attribute in the
bean:write tag.

try the following:


	<logic:iterate id="val" name="res" type="java.util.Map.Entry"
scope=session>
	     <bean:write name="val" property="key" />,
		<bean:write name="val" property="value" />
	</logic:iterate>
</logic:iterate>

Ciao
Michael

Hi,
I used logic:iterate tag on Hashtable and the next is happened:
the iterator returns Hashtable$Entry object instead of the object of the
original type, and the results is explicit - exception on bean actions. I
think, that appropriate lines in the IterateTag.doStartTag() code should be
changed to use Map.values().iterator() instead of Map.entrySet.iterator(),
that solves the problem.
