rich:collapsiblePanel expanded issue

[rjevans2000]

I am using a rich:collapsiblePanel and want it to be initially expanded based on some backing bean logic:

<rich:collapsiblePanel style="width: 350px"

                        header="Name" expanded="#{listEditorBean.listNotExpired(list)}" switchType="client">

......

</rich:collapsiblePanel>

However, the backing bean method NEVER gets called. If I set expanded="true" or expanded="false", then it behaves as expected.

Is there a limitation with this component which means you can't call a backing bean method from the expanded attribute?

I am using richfaces 4 M5
