ExtJS Find Node within Tree Branch
I'm trying to check whether a certain node exists beneath a branch of an ExtJS tree. Knowing the ID of the parent node, is there a library function to check whether a node exists beneath the parent (by its ID)?

I've checked the API numerous times over, and can only seem to accomplish this by iterating through the entire branch of the tree.

**Is there a library function which allows me to check if a child exists (by its ID) if the parent node ID is known?**

Thanks!

PS, to find the parent ID, I'm using the following:

    tree.getNodeById('myID');
