I am using igGridSorting with one column that has a compareFunc defined. When I use igGroupBy to group by a different column, and then sort by the column that has a compareFunc, the grouping gets all messed up. I investigated the problem and found that it is caused by the igGroupBy column uses the compareFunc of the sorted column when comparing. Further investigation found that it is because the compareFunc used when sorting is not initialized properly when there is no compareFunc defined for the column.
I changed infragistics.datasource.js line 2697 to the following so that the proper compareFunc will be used:
if ( (f.compareFunc === undefined) || (f.compareFunc === null) ) { compareValFunc = self._compareValues; } else if ($.type(f.compareFunc) === "function") {
Hello rsimm,
I prepared a sample in order to test the described from you behavior following your steps to reproduce. However grouping and sorting are independent of each other and when you define compareFunc for some column and group by another one, the grouping won't use this compareFunc. Attached is the sample for your reference. Please test it on your side and let me know if you have further questions.

Thank you for your patience.
I'm currently looking into this matter and will update you with some relevant information as soon as possible. At the meantime could you let me know the exact version that you're currently using?
Thank you for the reply.
There is no doubt that it is a development issue. If you pass it along to the development team, then they will see where they initialize the compareValFunc variable before going into a loop...that changes compareValFunc based on the options of the column. The bug is that it does not reset compareValFunc to the default value if the columns' option for compareFunc is null or undefined, thus it uses the previously set compareValFunc (which in this case was set from the previous columns compareFunc option).
Unfortunately I don't have time right now to work up a sample app, but it should be pretty easy.
The described behavior may or not be a development issue, however I need a sample that reproduces it. Please send me such one, so that I can test this behavior on my side.
