3055064 - Exception in UI Component after binding an Action


You can see an exception thrown in the UI on loading a UI Component after you have bound a Business Object (BO) Action.


  • SAP Business ByDesign
  • SAP Cloud Applications Studio
  • SAP Cloud for Customer

Reproducing the Issue


  • You have created an Add-On Solution.
  • You have enhanced a screen with an Action using the Extensibility Explorer in the UI Designer.

Steps to reproduce:

  1. Log into the system UI with a Business User.
  2. The exception is thrown immediately when the UI Component is being loaded in the UI.


Case 1:

The Action in the binding no longer exists on the BO.

Case 2:

The Action is bound via a Virtual Association (VA) path, for example, actionPath="Root-.[SalesDocuments]-.CustomerQuote->doThis" in the XML (where Root refers to the Opportunity BO and [SalesDocuments] is the VA).


Case 1:

Check that the Action binding is correct and reactivate BO and rebind on the UI Component if required.

Case 2:

VA actionPath is not supported by the system as it expects to find the action directly on the Opportunity-BTDReference Node.
