jQuery Grid Plugin - jqGrid

 a field with 3 possible values : 0,1,2
 
 a colModel for this field :
 
 {name:'ADHERENTS',index:'ADHERENTS', width:colwidthBOOL, align:"center", sortable:false, formatter: adherentsFmatter,  editable:true, edittype:'select', editoptions: {value: adher_editSelOpts}, editrules:{}, searchoptions:{sopt:['eq'], dataInit:function(elem) { $(elem).val('0');}}},

a editoptions => adher_editSelOpts :
var adher_editSelOpts = { 0 :"Non autorisé", 1: "En consultation", 2: "En modification" };

formatter and unformatters :

function adherentsFmatter(cellvalue, options, rowObject){
    switch (cellvalue) {
       case '0': html=''; break;
       case '1': html='<span class="icon-redmond-document"></span>'; break;
       case '2': html='<span class="icon-redmond-edit"></span>'; break;
       default: html='';
    }
    return html;
}
function adherentsUNFmatter(cellvalue, options, cellobject){
    var spanClass= jQuery(cellobject).children().eq(0).attr("class");
    switch (spanClass) {
       case 'icon-redmond-document': val=1; break;
       case 'icon-redmond-edit': val=2; break;
       default: val=0;
    }
    return val;
}

the formatter is OK in listmode and in viewmode;

in edit mode, the select tag is wrong against the value;

I think the unformatter function is no good; it's difficult to know where the unformatter do his work;

Thank you for any help.

Olivier.
