treeConnector->render_array() generates a notice

Hi, the code is like:

$tree->render_array($data, "id", "name", "", "fid");

Even if the $data is not empty, there is a notice as below:
PHP Notice: Undefined variable: result in \dhtmlxConnector1.5\db_common.php on line 1065

And the xml can output normally.

Please try to update PHP files with latest one from github

Thanks for quick reply.
I downloaded the files from github and overwrite the original ones, and found no difference from the original ones (from version control system). So the problem remains.

Sorry, you are right.
Please grab the updated db_common.php, now it must work correctly. … common.php

Thanks, Stanislav,
Now it works very fine.
