I created a Ctools Multistep form. Its working fine. But when a user opens this multistep form in two tabs and fill the form fields simultaneously and submits it, both the submitted forms have same values for all the fields. Means both the submissions have same data.
When I have submitted this form in different browsers simultaneously, then both submissions have their own data.
I followed this tutorial to make Ctools Multistep form : http://www.xenyomedia.com/content/4-steps-form-multistep-form-ctools
I think, the problem is with $object_id = 'ctools_multistep';, because its same for both the forms in different tabs. Thats why it creates the same submissions for both forms.
Can anyone help me regarding this?
