Florent Guillaume commented on NXP-2784:
----------------------------------------
Committed for 5.1:
You can now have a "leafFilterClass" filter in your treeManagerPlugin extension
point:
<extension target="treeManagerComponentBase" point="display">
<treeManagerPlugin>
<showFiles>false</showFiles>
<showSection>true</showSection>
<leafFilterClass>org.nuxeo.ecm.webapp.navigation.FolderLeafFilter</leafFilterClass>
</treeManagerPlugin>
</extension>
Note that for 5.2 the extension point will be in another place because the Tree
implementation has been completely refactored there.
> Add filter for the navigation tree to avoid getting the children of some big
> folders

> Original Estimate: 2 hours
> Remaining Estimate: 2 hours

> The JSF navigation tree (on the left) displays a + in front of nodes that are
> folderish, to allow opening them to see their sub-folders. To do that it
> needs to call getChildren().
> On big folders that contain only documents, this is extremely costly.
> Therefore, a way to mark some folder as "don't get its children for the tree"
> is needed.
> This can be added as a new "leaf filter" for the tree manager.
