Tab application problems

I created a tab application which works w.o. problems stand-alone
Then I integrate it into a container. Then problems arise. On the form I get the message:

Notice: Undefined index: aba_saida in C:\Program Files (x86)\NetMake\v7\wwwroot\scriptcase\app\DOHMWeb	ab_medicaldossier\index.php on line 428

While generating (but generation completes fully) I get the following errormessage in the ‘send to netmake’ window.

the class TabbedAppFieldsEditionDef of the module Interface was not found. | Script: C:\Program Files (x86)\NetMake\v7\wwwroot\scriptcase\devel\lib\php\functions.inc.php linha: 1153

I wonder what’s going on here. Also the screen becomes corrupted. I can only solve above issue if i don’t use an exit button (which is ok, but still a bug). The below issue is something strange, but happens regularly with the tab application:
