At version 4.2.0 is error in displaying edit form if any column has “formoptions” with “rowpos”.

For example formoptions: { rowpos:1}

Displayed form has under form elements (inputs) any “dumped” elements like:

undefined[object HTMLTableRowElement][object HTMLTableRowElement][object HTMLTableRowElement][object HTMLTableRowElement][object HTMLTableRowElement].

Without rowpos is it ok.
