I saw Cautions and Limitations in treeGrid article.

"Currently it is not recommended to combine inline editing and form editing with treegrid, or the expanded column will not be editable."

I think it's been canceled.

But I download jquery.jqGrid-4.3.1 version, It is still invoke errorfunc.

Please, help me.
