How to disable ExtJs validation errors during reload? -


i have dependent combo box required. when parent combo box value selected, dependent combo cleared , store reloaded. how keep extjs validation error showing during reload?

            new ext.form.combobox({                 id: 'ddlmake',                 store: makestore,                 displayfield: 'description',                 valuefield: 'typecode',                 width: 110,                 typeahead: true,                 mode: 'local',                 forceselection: true,                 triggeraction: 'all',                 emptytext: 'select make',                 selectonfocus: true,                 allowblank: false,                 listeners:                     {                         select: function (combo, record, index) {                             var selval = ext.getcmp('ddlmake').getvalue();                             var modelcombo = ext.getcmp('ddlmodel');                             modelcombo.setvalue('');                             modelcombo.store.reload({                                 params: { categorytypecode: 'model', subcategorytypecode: selval }                             });                         }                     }             }),             new ext.form.combobox({                 id: 'ddlmodel',                 store: modelstore,                 displayfield: 'description',                 valuefield: 'typecode',                 width: 110,                 typeahead: true,                 mode: 'local',                 forceselection: true,                 triggeraction: 'all',                 emptytext: 'select model',                 selectonfocus: true,                 allowblank: false             }),

the reset() method clear validation messages. here ended using:

function loadmodelcombo(combo, record, index) {     var selval = ext.getcmp('ddlmake').getvalue();      if (selval != '') {         var modelcombo = ext.getcmp('ddlmodel');         modelcombo.setvalue('');         modelcombo.store.reload({             params: { categorytypecode: 'model', subcategorytypecode: selval }         });         modelcombo.reset();     } }
