[TYPO3-dev] 4.5 pagetree API to get page uids of all subpages of a page

[Steffen Müller]

Hi.

I am developing two clickmenu items for the new pagetree in 4.5 to 
delete the page cache of
1) a single page (clearPageCache)
2) a page with all its subpages (clearBranchCache).

Part 1) is already working.

Part 2) lacks of a good way to fetch subpages recursively. 
Unfortunately, t3lib_TCEmain::clear_cacheCmd() does not provide a way to 
recursively clear the page cache of a given page id. So I guess I have 
to do that myself.
I am looking for a way to get the uids of all subpages (children) of a 
page.

My extension looks like this:

JS:
Ext.onReady(function() {
   Ext.apply(TYPO3.Components.PageTree.Actions, {
     clearBranchCache: function(node, tree) {
       TYPO3.Smclearcachecm.ClickmenuAction.clearBranchCache(
         node.attributes.nodeData
       );
     }
   });
});

PHP:
public function clearBranchCache($nodeData) {
   $node = t3lib_div::makeInstance('t3lib_tree_pagetree_Node', (array) 
$nodeData);
}

I tried to use
$node->getChildNodes()
$node->hasChildNodes()
which are members of inherited t3lib_tree_Node. The result is always NULL.

What's missing here? How do I get childNodes? Does the pagetree API 
provide such function?

Thanks for your suggestions.
