jQuery Grid Plugin - jqGrid

Not sure if anyone else has encountered this but having recently switched to jqGrid 4.0.0 I have encountered an issue with the successfunc in the saverow function.

Ever since the upgrade my successfunc was no longer getting called, and my task was not completing.

Having debugged through the jquery.jqGrid.src.js file I have discovered this line:

8295: if( $.isFunction(o.succesfunc)) { ret = o.succesfunc.call($t, res);}

It is checking if o.succesfunc is a function and if so, using it as the next step in the process. The only problem being that o.succesfunc does not exist so it will never be true. The o element contains o.successfunc (which in my case is a valid function.) Everything began to run fine once I changed the line to:

if( $.isFunction(o.successfunc)) { ret = o.successfunc.call($t, res);}
