After we have updated the SAP Netweaver BI from 7.3 to 7.4, the developpers are having issues with the BEx Web Application Designer when you want to adjust there web templates they had and used on the 7.3.
The are getting the error as example like in the discussion title
E2 Error executing TEMPLATE_PARAMETERS on object item (while trying to invoke the method java.lang.String)
See attached image in this thread.
Any ideas on how to be able to solve this?
