Description
I've been using this page structure for quite some time and it seems after upgrading to 4.1.5 from 4.1.1 something has regressed. It appears my BorderTab component is caching the page or page class when it shouldn't? essentially, i have a border component which wraps the bodyContent in a generic Form component. Inside this form (yet still inside the Border) i have some BorderTab components, each with a LinkSubmit component. Clicking these links navigates through the tabs, submitting their forms (empty in the example).
Please run the attached example war file, it includes everything.
1. click tab 1, tab 2, tab 3 etc - eventually the ClassCastException will be shown.
note: clicking tab 1 recursively without clicking the other tabs does not cause the exception
Exception message:
Unable to update OGNL expression '<parsed OGNL expression>' of $ApplicationComponent_8@202687d[Page2/$Border.$BorderTab_1] to Page3: $Page2_15 cannot be cast to $Page1_14
