Problem with Ext.ux.Fileup

[neoraptor]

Hello,

I have actually a problem with the extension Ext.ux.Fileup.

I want to send a picture and use the callback to send a form, with some fields plus the imageUrl from the callback.

The method is called when the image is upload and the response url is correct. However, I can't access to the getPatientForm() auto-generated method (patientForm is in refs section).
I got the following error :

Uncaught TypeError: Object [object Object] has no method 'getPatientForm'

Please note that if I use the autoupload feature and then submit the form, everything is ok. However, I can't avoid user to upload images without sending the form in this case
That's why I want to send the image when I submit the form.

Here is my controller code so far :

   savePatient: function(options) {
      var fileBtn = Ext.getCmp('fileBtn');
      
      fileBtn.submit();
   },

// Upload button initialisation
   onFileBtnInit: function(fileBtn) {
      var me = this;
      fileBtn.setCallbacks({
         scope: this.getPatientForm(),
         success: me.onFileUploadSuccess,
         failure: me.onFileUploadFailure
      });
   },

 onFileUploadSuccess: function(response) {
      console.log('Success');
      Ext.getCmp('imageUrl')
         .setValue(response.url);
         console.log(this)
         var patientForm = this.getPatientForm();
         var newValues = patientForm.getValues();
         var store = Ext.StoreManager.lookup('patientStore');
         var test = Ext.ModelMgr.create(newValues, 'iWound.model.patientModel');
         var errors = test.validate();


         if (!errors.isValid()) {
            Ext.Msg.alert('Error', 'Fail to save patient ' + newValues.name + '<br/><i>' + errors.items[0]._field + " " + errors.items[0]._message + '</i>', Ext.emptyFn);
         } else {
            store.add(test);
            store.sync();
            Ext.Msg.alert('User added', 'User ' + newValues.name + ' was added successfully', Ext.emptyFn);
         }
}

How could I retrieve the patientForm method?

Problem solved : you can retrieve the context with this._callbacks.scope
