Error after reload the standard XML file in UWL Configuration Wizard

Hi all,

We are working with UWL (EP7sp10) and encountered a problem. The UWL Configuration Wizard gave an error. We found on SDN/WIKI a posting with a workaround (<a href="https://www.sdn.sap.com/irj/sdn/wiki?path=/display/BPX/UWL%2bConfiguration%2bWizard%2bshows%2bempty%2bdropdown">WIKI - UWL Configuration Wizard shows empty dropdown</a>)

We tried this working around, but it did not work. We uploaded the standard XML file again. Now we cannot access the link "Customize the look of the UWL main page" in UWL Administration.

We get a shortdump: 500 Internal Server Error

It seems getting wrong at: dropDownEntryComboMaincom.sap.pct.erp.mss.Alert

What do I have to do now? Also a clean XML file upload from another SNP installation did not work.

Best regards,

Hi Leurs,

Try doing the following:

1. Upload the new Standard XML file from the another portal server with same support version or replace the changes u made to original and upload

2. Remove the cache

3. Register for all systems

4. preview the UWL iView.

Hi Vinoth,

Thanks for you reply, but these steps I have taken already; without result.

Hope that you know more of how to go back to the previous version.

At last we can put a back-up of the portal server.

Thanks a lot

Hello,

I have solved the problem I was facing. There was a Configuration name ending with **.zip which was giving the error. I deleted this Configuration Name and cleared all caches again.

      • Now, the dropdown box is empty again ***

Best regards,

G. Leurs
