jQuery Grid Plugin - jqGrid

Hi

I found a bug in grid.subgrid.js that's easily solveable...

If you set subgridtype to point to a function jqgrid will fail in line 95 (git respository content on the 16th of december 2009) because it tries to call toLowerCase on the subgridtype value, which the function doesn't support. A simple test for the function and an else in which toLowerCase and the switch appears should solve it:

-----------------------------------------------------------------------------------------------------------------

if(!ts.grid.hDiv.loading) {
				ts.grid.hDiv.loading = true;
				$("#load_"+ts.p.id).show();
				if(!ts.p.subgridtype) ts.p.subgridtype = ts.p.datatype;
			-->	if($.isFunction(ts.p.subgridtype)) {
                                     ts.p.subgridtype(dp);
				} else {
				ts.p.subgridtype = ts.p.subgridtype.toLowerCase();
				switch(ts.p.subgridtype) {
					case "xml":
					case "json":
					$.ajax($.extend({
						type:ts.p.mtype,
						url: ts.p.subGridUrl,
						dataType:ts.p.subgridtype,
						data: $.isFunction(ts.p.serializeSubGridData)? ts.p.serializeSubGridData(dp) : dp,
						complete: function(sxml) {
							if(ts.p.subgridtype == "xml")
								subGridXml(sxml.responseXML, sid);
							else {
								subGridJson($.jgrid.parse(sxml.responseText),sid);
							}
							sxml=null;
						}
					}, $.jgrid.ajaxOptions, ts.p.ajaxSubgridOptions || {}));
					break;
				}
                             }
			}
