Also:

with the actual build when you complete an insert in a row of a subgrid in way editonline (rowaction=true, inlineadd=true) you have the following error:

SyntaxError: JSON.parse: unexpected end of data phpgrid

and the add button remains obscured; to continue you must refresh the grid.

Nothing with the previous version

Also:
in a grid with multiselect it's impossible to choose any row; the response is always: please select row
in another grid with 4 subgrids there is an alert empty

1) For datepicker fix, i've emailed you updated build
2) For JSON error, please check firebug > ajax > response. It looks like some other debug data is echo'd beside JSON.
3) For multiselect, please share screenshot of the issue. I am unable to understand this.

Note: Please create separate ticket for each case. Othewise email me all queries at [email protected]
