Link: http://myserver.mydomain/radicore/test/x_tree_node%28tree2%2 9.php?session_name=menu0&expand=25#25

The page loads fine, but when I expand the '+', I get some kind of infinite recursion, I guess....

( ! ) Fatal error: Maximum function nesting level of '100' reached, aborting! in C:\xampp\radicore\includes\include.library.inc on line 1401

That code looks correct, and it works OK on both my local PC and the radicore web site. If you are running the code in the "Example" subsystem you may want to try unzipping it again as it may be corrupted. If this is your own code you have tried building from the tutorial then I suggest you compare it with what is in the "Example" subsystem.

I cannot immediately see what is wrong, but it looks like it is looping when it is looking for child nodes. You will have to step through with your debugger to see what SQL query is being generated and then what happens when that query is executed.

What version of the framework are you running?

I am running the version 1.89 from May 5th, 2015.
I was following along the tutorial. There is a good chance that I missed a step along the line.

You should compare the code you have written with that which is contained within the "XAMPLE" subsystem as the tutorial is suppsed to duplicate this code. If you see any mistakes in the tutorial can you please let me now so that I can correct it.
