Hello Tony,

I exanined strange problem where dataInit was called multiple times: one time with Number as parameter like 0 (???) and the second time with DOM element as parameter. Because the code like $(0).datepicker() produce no exception typical code work correctly, but other kind of usage of input parameter can follow to error.

The reason of the strange behavior is in the line of setAttributes function from the grid.common.js module. The line

exclude = $.extend(exclude, exl);

will be used to merge exl array with the array holding some standard attributes

var exclude = ['dataInit','dataEvents','dataUrl', 'buildSelect','sopt', 'searchhidden', 'defaultValue', 'attr'];

The problem is that $.extend don't work with arrays and in case of exl=['value'] for example (see the line) replace first elements instead of merging. In the example with ['value'] one get

['value','dataEvents','dataUrl', 'buildSelect','sopt', 'searchhidden', 'defaultValue', 'attr']

instead of

['dataInit','dataEvents','dataUrl', 'buildSelect','sopt', 'searchhidden', 'defaultValue', 'attr', 'value']

As the result the line $(elm).attr(key,value); will be used for dataInit and the function will be called with wrong parameter.

To fix the problem one should just replace the line

exclude = $.extend(exclude, exl);

to the line

$.merge(exclude, exl);

Best regards
Oleg
