[Flow] Catch Exception while property mapping - Object with identity not found

[David Sporer]

Hey guys,

 

how can I catch the exceptions if a user tries to open a page where an
object id is in the url that is no longer existant?

Currently an exception is thrown a la "Exception while property mapping for
target type xxx - Object with identity blablabla not found".

I'd like to redirect the user to another page that just tells him a generic
error-flashmessage.

 

Is that possible?

 

Best regards

David
