I cannot use the popup node form option as editor on any fields I try to use it to, be it node, cck or non-cck. That wouldn't pose a problem if the text cell option is available. However text cell is not available on all fields and only popup form is always available among fields but it doesn't seem to work returning a warning:

"warning: missing argument 2 for slickgrid_node_form_pre_render(), called in ~/common.inc on line 2988 and defined in ~/slickgrid/slickgrid.module"

I need the popup node form to work or make text cell editor available on all fields.
