context mapping produces error

[Former Member]

Hi!

I have a problem in the Web Dynpro Tutorial.

I successfully had the first Tutorial running some months ago. Last week I tried to recreate it again to get all back in mind. But I didn't succeed the second time. The problem is the context mapping. When I map an input field (text) into the controller context of the app, then the server gives me the following error:

An error has occurred:

"Failed to process the request."

Please contact your system administrator.

Show Details

on show details I get a stack trace:

Error stacktrace:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for view com.plecto.nw.wd.tutorial1.StartView. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

When I unable the context mapping, the app runs fine, just without mapping.

I tried to make the second tutorial(quiz), but the same problem appears when it comes to context mapping.

Please help, All my colleagues haev no idea about it.

thanks in advance

Stefan

Hi,

Is your NDS and WebAS server of the same version ?It should be the same !

Thanks, the version conflict produced the problem.

I recall saying "never change a running system"

Hi Werner,

This problem comes generally with wrong context mapping. Remove context mapping for all and then try to map it again. I guess you have mapped one view attribute to the component attribute. Then, you have deleted component attribute later.

This also could be the problem.

Are you using RFC in your application?
