jQuery Grid Plugin - jqGrid

using 4.1.2

I have discovered some wierd result in FormEditing when using a grid which has had the columnsRemapped ( i unhide, resort, rehide columns in that routine ). The error coming back is

g.p.colModell[i] is undefined   jquery.jqGrid.src.js

5389 -                 for( i =0, len=g.p.colModel.length;i<len; i++){
                    if(g.p.colModel[i].name==valref) {
                        edtrul = g.p.colModel[i].editrules;
                        valref = i;
                        try { nm = g.p.colModel[i].formoptions.label; } catch (e) {}
                        break;
                    }

If I turn off remapping the columns the colModel object does not contain a spurious 0 undefined item at the top; however with colModel remapping enabled the g.p.colModel looks like

That 0 undefined is appearing from a remap ;

Hold up a moment though :  I examined the rv value of remap and set it to 0-count of columns ( -1 ) and it worked correctly . Which means the value of rv if it contains more indices than the columns your using then it makes  a problem for colModel[i] technically leaving the fault -- my bad ! lets close this while I go away and drink some more coffee; thanks for helping though.
