I am facing issues with 8.2 ,although things were fine in 8.1.4 but now I have a panel which also contains tabpanel. So I the child panel I am trying ti show the form but it throws error and also due to this (I guess) I am also unable to see my parent panel form (i.e everything is blank)
Error: Can't show form supplier_article_lst when the parent form FormController[form: article_tab, fs size:0, selected record: null,destroyed:false] or the component + <tabs> is not visible
and also this
Error: Access to component calculated_articletype_id property dataproviderID denied (visible). Warning was caused by: Access to component ng$article_dtl property null denied (visible)
I keep on getting such error several times.
