JqGrid "addRowData" for "first" does not work

I cannot add a row to the top of the jqGrid table using a row:

jQuery("#myTable").jqGrid('addRowData', 0, myData, "first");

It simply adds to the bottom of the list, as usual.

Has anyone tried this and worked for them?

In my table, previously added rows have an index that goes from 0 to N

I am using jqGrid v3.8.1 and jQuery 1.4.3

It is a pity that you do not publish the full JavaScript code that you use. Therefore, I can only guess what is happening.

For example, if you define myDataan array ( [...]) instead of an object ( {...}), the position parameter will be overwritten with the value "last".
