undefined default GUI values

[kmq]

When defining a new GUI element in source:/trunk/mapbender/http/php/mod_editElements.php​, leaving the "On/OFF" or "Position" fields empty, causes the the following error message when saving:

"sql error: ERROR: invalid input syntax for integer: "" ROLLBACK performed."

That is an undesirable outcome, as it leaves no clue as to what actually went wrong.

Proposed fix: Give default values to $e_pos and $e_public.

I fixed this bug

• default values: e_pos 2 and e_public 1

in the script:

		if($e_pos == ''){$e_pos = 2;}
		if($e_public == ''){$e_public = 1;}	

Have a look at revision 4075
