I'm trying to display a dataTable, for which the value attribute is a Collection, obtained by calling the values() method on a HashMap.
Although the resulting object is definitely a Collection type, and to my knowledge, should therefore be correctly rendered by
JSF, it fails with the following message:
Error getting property 'myProp' from bean of type java.util.HashMap$Values
The dataTable is constructed like this:
<h:dataTable id="items"
value="#{myBean.items}"
var="item">
<h:column >
<h:outputText value="#{item.myProp}"/>
</h:column>
</h:dataTable>
A workaround for this problem is in the bean to wrap the HashMap.values() collection in an ArrayList before returning it.
However, I'd rather have a properly working dataTable!
Has somebody else encountered this problem? I couldn't find anything.
Tom
