There are two issues I want to report. If they are bugs og features, I don't know, but they cause trouble for our application if we are supposed to upgrade from 1.4.18 to 1.5.2.
Issue 1 - Multiple tabs: We have two pages with forms, open up PageA in one tab and PageB in a second tab (in this order). Then we fill in data in PageA and submit, and then open tab with PageB and fill in data. If we check the model and domain objects none of the submits have been attached to the model. Only the newest opened tab is actually submitting data to the model.
Issue 2 - Back button: We have two pages with forms - fill in data in PageA and submit - this redirects to PageB (also has a form) and use the back button to get to PageA. Now we change values and submit again. The new values are not submitted to the model.
I'll attach a quickstart on this.
