Thanks for this.

1. This feature and not bug. Every method has its own mtype. You just should read the docs.

2. The bug is fixed in GitHub and will be avialble soon:

1- I set mtype:"GET" but using toolbar buttons to edit,add,del, always POST method is used.
I found a workariund definining a custom functions on navGrid to call editGridRow and setting mtype on properties.

2- using delGridRow(rwid, { mtype: "GET", afterComplete: saveRow }); always return "H.split not defined", I've tried every types for rwid: string,array, comma separeted string, no way !

I solved it changing the sour ce code at line 8277 (ver. 4.3.1):

 var toarr = [];
if(postdata.constructor.toString().indexOf("Array")==-1)
              toarr = postdata.split(",");
