Failed to create delegate for component

[Former Member]

Hi All,

Today when I try to run my web dynpro application, I got a 500 internal error. I've tried to rebuild and regenerate the application, and everything works fine. But I still got the error:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component com.cobest.sc_os_sale.dc_wdp_styledev.StyleInfoComp. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

I have deployed that DC firstly.

Sharanya , you are right, one of my colleague tryied to implement the callableObject interface, but later he found that he don't have to do that, so he just deleted that interface. Do you think it is the root cause?

hai yining,

check if any of the library references are missing.That will cause such errors.

If using gp check for caf_eugp~api

Thanks n Regards

Hi,

deploy this "com.cobest.sc_os_sale.dc_wdp_styledev.StyleInfoComp" component first.
