ashutosh_rastogi · ‎10-18-2006

I have created an entity service and have used Object Selector(Searchbar and List) and Object Editor UI pattern to Select and Edit objects.

Now when i am trying to delete some object i am gettign the following exception:

"The following exception occured while processing your request: com.sap.caf.rt.exception.CAFDeleteException"

Please suggest how to resolve the problem.

It seems problem with deployed metadata. So, try the following:

1. Start SDM. Go to "Undeployment" tab.

2. Select all the your custom composite projects and undeploy them. It's important to undeploy the <project_name>/metadata, but also undeploy another project stuff like dictionary, permissions, webdynpro ... Do NOT undeploy CAF related metadata applications.

3. After that create a simple composite project with one business entity and deploy it(do not forget save all, regenerate all and build it). And check creation/deletion for this deployed entity in service browser. Also be sure that only your composite project is visible in service browser(except of caf.core and caf.tc). If some another project is available in service browser except of these(yours one, caf.core and caf.tc) it means that some project is not yet undeployed.

If the problem will be reproduced again please provide your email - we will try to find the issue source in another way.

hi I m getting an UI pattern object selector login error while creating new configuration.

Hi Aliaksei,

You are right, the problem was due to inconsistent metadata. It is working when i created a new entity in a new CAF project.

Thanks

You need also migrate you engine to SP10 too, not only CAF. The SP levels must be the same for all components deployed on your server.

I don't know exactly whether or not SP10 is available on market service place. Actually you need to bring up the question with project management.

Hi Ashutosh,

It seems that deployed CAF version is SP9 but not SP10. Or very old sp10.

I recommend you to check version firsly and if it's SP9 migrate your CAF and engine version to SP10.

If you have difficulties with deployed version determination just let me know.

Best regards,

Then check the default trace log \usr\sap\<instance name>\JC<id>\j2ee\cluster\server0\log\defaultTrace.X.trc for exceptions and put related to "com.sap.caf.rt.exception.CAFDeleteException" exception to the thread.

So, click the "!" near the error message in service browser and copy exception to the thread.

Hi Ashutosh,

Firstly, try to delete an entry using Service Browser. If the same problem will be reproduced click the "!" image near the error message in order to check exception.

Also, check server instance default log and put the exception to this thread.
