Web UI - Exception condition "TYPE_NOT_FOUND"

Dear All,

I have a problem in the proper functioning of the Web UI:

- I created two custom configured fields in order to select all the active event handlers having a specific event handler type (such as the standard fields "TRA10_EH_ACTIVE" and "TRA10_EH_TYPE_ROAD") and I added them in my Selection Profile.

- Now, when I search for the Event Handlers in the Web UI I always have this dump: "500 SAP Internal Server Error - Exception condition "TYPE_NOT_FOUND" triggered".

In the past I already had this kind of error and I solved applying the SAP note 1153145, but this time it doesn't solve the issue: can anyone help me?

Best regards,

Pietro
