parallel submitting forms

Hello,

I wonder if its possible to submit form in background same as in normal ajax request. Problem is the new request always cancel/abort the previous one.

I'm submiting via javascript

_stack.push(function(di) {               
  di.getService('formLocator').getForm(formid).submit();
});

is there somewhere option to add backgoud:true same as in

di.getService('page').open();

or submit the form by other way?

Thanks a lot!
