af:tree hide child icon

Alex GrigorApr 20 2015 — edited Apr 22 2015

We are using <af:tree/> component in our application and the tree is populated using a POJO Data Control.

If the tree contains a leaf node (no children) first time when it's displayed, thedisclosecollapsed_ena.pngicon is displayed. After you click on it, it does disappear.

We don't want to show it from the beginning, is this possible? If it is, how can it be done?

Thank you,

Alex

I also found that approach, but I would like to know if there is more "classic" one. One provided by the Framework. I consider that one as being a bit of a "hack".

Thank you for the response.

if you expand all nodes then expand icon will not be visible on nodes that doesn't have any child

try setting initiallyExpanded property of tree to true

Thank you Ashish,

Yes, I know that, but our requirements says that the tree must not be initially expanded.

I was thinking about a way to apply specific css classes for the each node and then using that class to override/remove the default icon. Something like this:

styleClass="#{node.childrenSize eq 0 ? 'ChildNode' : 'ParentNode'}" the problem is that i could only apply this classes to the <af:outputText /> and the icon is outside this component. Is there way to change the icon based on the css class?
