if i use a datatype of function for a grid, example:

...
jQuery("#list").jqGrid({
datatype: getFromFunction,
...

i find that anytime i have to specify a parameter for the function, or if i follow the function name with (), i get an error in Internet Explorer, and the grids dont always work. Firefox always works. The javascript error is always:

Line: 13

Char: 7209

Error: Object Required

Code: 0

the setGridParam fails in a similar way. if i use:

setGridParam({ datatype: getFromFunction(data.dataobject), page: 1 })

I get the same error in IE, and data fails to load correctly... no problem in Firefox.

am I missing something?

You cant specify a parameter like that - think about it for a while: thats a function call. So it calls the function, and tries to use the return value as the datatype...

If you need to pass a parameter to your function, you will need to use a wrapper function:

setGridParam({ datatype: function() {return getFromFunction(data.dataobject)}, page: 1 })

But you also need to be aware of scoping issues...
