[matus_b]

Hi,
the exception is reproducible on SmartClient Version: v10.0p_2016-06-15/LGPL Development Only (built 2016-06-15) showcase and FF browser.

Open the Grids -> Editing -> Custom Cell Editors
Click on the grid to start editing.
Following exception is thrown:

We need fix to be in version 5.0. Upgrading question was already discussed here: wrong-dynamicform-height-when-formitemsection-is-hidden
Thank you

This has been fixed in SmartGWT 5.0 / SmartClient 10.0 for builds dated June 25 and later.
