ExtJS textfield validation — too much recursion

ExtJS textfield validation was returning error “too much recursion” when I was trying to add a listener in the text field. After digging into my code I saw following piece of code:

TextField listener

listeners : {
valid : validateAddDoctorForm


Listener method description:

var validateAddDoctorForm = function() {
var saveButton = Ext.getCmp('save_doctor_button');
if ( createDoctorPanel.getForm().isValid() === false ) {
} else {

Apparently, using valid or invalid events with isValid function of the form seem to cause infinite recursion. Hence, if at all you have to enable or disable any button based on validity of a certain field using “valid” or “invalid” event, make sure you don’t check validity of complete form all over again.
