RichFaces 4 expand whole tree

[kwutzke]

Hello,

I would like to display the whole tree expanded when the page is loaded the first time. Edit: It would be okay to have some functionality to programmatically expand the whole tree, e.g. via button or similar.

I found this for RichFaces 3:

http://community.jboss.org/message/30212

...but how is it done in RichFaces 4? There doesn't seem to be an adviseNodeOpened attribute for RichFaces 4 rich:tree.

How is it done?

It would be nice to find out how to expand the whole tree at all. The first load is not as important.

Can anybody help?

Hi, Chelachen.

Unfortunately your suggestion doesn't work for me. Any new ideas?

            <h:outputText value="${dir.class.simpleName} - " />

            <h:outputLink value="/admin/edit${dir.class.simpleName}.xhtml?id=${dir.id}">
