SAP Note
Header Data
Symptom
In the case of Web Dynpro ABAP applications, an "Assertion failed" exception occurs in the method DISPATCH_NW7_EVENT of the ABAP classCL_NW7_VIEW_ELEMENT_ADAPTER.
Other Terms
WDA adapter 12152
Reason and Prerequisites
The back-end system receives an event for a UI element that does not exist or no longer exists by means of an HTTP request.
This is an inconsistent state that must be analyzed..
Solution
Implement the attached correction to suppress the error in production systems. The correction delivered with this SAP Note does not solve theproblem. Following the implementation of the correction, the error no longer results in a program termination in a production system.
Caution: This SAP Note does not rectify the cause of the problem.
The problem must be analyzed to find its cause. Known causes:
l You use automatic test programs or load runners that play back a previously recorded HTTP process. In this case, the solution is to carry outthe recording using the URL parameter sap-wd-stableids=X.
See http://help.sap.com/saphelp_nw74/helpdata/en/73/142b2a79fb4884a4b4e87fa88f4115/content.htm.
l The timeouts of the HTTP connection and ABAP session have different values; the value for the HTTP connection is too low. The browsergenerates the error log entry "Network error caused by IE and Server with status=12152, resend compete request [..]" if the client trace isactivated (to activate the client trace, see SAP Note 884424). The solution here is to increase the timeout value. For more information, seeSAP Note 824554.
l You use integration scenarios such as Microsoft Silverlight Islands or Adobe Flash Islands. Events are triggered while processing is takingplace in parallel in the back-end system. The solution is to register for the lock and unlock events in the relevant integration technology and tomake sure that none of your own events are thrown during the lock phase.
