Iterate through a List of Maps
Hello all, I'm trying to iterate through a List of Maps(I have a method
"public List<Map> getRecords()" in the action) using s:iterator. I can
iterate through the List without problems, but I can not get it to iterate
through the entries of the map. So far I've got this:
[..]
<s:iterator value="records" status="recordsStatus" var="record">
<s:if test="#recordsStatus.index ==0">
<tr>
<td colspan="*"></td>
</tr>
</s:if>
<tr>
<s:iterator value="record.entrySet()" status="fieldStatus">
<td>
<s:property value="key"/>/<s:property value="value"/>
</td>
</s:iterator>
</tr>
</s:iterator>
[..]
The tag generates the
<tr></tr>
for each entry, but it is not going through the second iterator, so I
suppose I'm doing something wrong with the value attribute. Can you help me
with it?
Thanks
Jose

That was fast! The version is 2.1.8.1. I'm gonna try your suggestion right
now, and let you now.
Thanks

yes try adding "#" before "record" -> "#record"
and since record is a map you can iterate through it directly without
calling entrySet()

What version? Early versions sometimes required a "#" before the
variable name when referencing vars defined by things like an iterator
tag.
