How to know that the space has no child space ?

[vpoorboy]

Hi,
In browse.jsp, I put an evaluator for my test

<a:booleanEvaluator value="#{BrowseBean.nodes == null}">
<hutputText value="Hello"/>
</a:booleanEvaluator>

But this has no effect. Can somebody show me how to know that the current space "has no "/has child space ? And how to know that it "has no"/has file(s) (content) ?

It's urgent, pls help !
Thanks !

Try the following instead:

<a:booleanEvaluator value="#{empty BrowseBean.nodes}">
   <h:outputText value="Hello"/>
</a:booleanEvaluator>

Thank you, Gavinc !
I see that we can use another way

<a:booleanEvaluator value="#{BrowseBean.nodes[0] == null}">
