Extjs4 - remote validation

Question

I\'d like having a remote validator for a textfield. My PHP returns true/false value. I\'ve tried something like this:

{
   xtype: \'textfield\',
   fieldLabel:

maybe you shouldnt use the validator then, add a listner on change for the textfield and use the methods markInvalid and clearInvalid for displaying the validation.

{
   xtype: 'textfield',
   fieldLabel: 'Field',
   allowBlank: false,
   textValid: false,
   validator: function(){
       return this.textValid;
   },
   listeners : {
     'change': function(textfield,newValue,oldValue) {
        Ext.Ajax.request({
          url: 'psc/validate',
          params: { psc: value },
          scope: textfield,
          success: function(response){
             if (response.responseText){
               this.clearInvalid();
               this.textValid = true;
             } else {
               this.markInvalid('field is not valid');
               this.textValid = false;
             }                             
          }
        });
      }       
   }
}

I haven;t tried it but could work for your aproach

EDIT i've made some modifications to the code to include the validator..
