I am getting problem in submission of form( xtype:'form').While submitting form the params values are getting submitted but the items that are there in form are not getting submitted. I have tried the same by changing params to baseParams but still facing the same problem. form.form.submit({ url: params:{ //items mentioned here are getting submitted } }); BUT I need the items that are there in the form to be submitted along with params or baseParams items. form.getForm().submit() is also creating the same problem.
