hai Phani Kumar,

when it gives an error

Failed to create delegate for custom controller there may be some prob in library reference.you may have missed creating some reference.

To create a lib reference.

Rt.click on the project->properties->select web dynpro references in the left panel and ->choose lib references tab->click on add button->

type the reference which is missing.click apply and then clk ok.

Hi Thanks One and All.

Issue is resolved.

We rebuild the DC's and deployed it again then every thing is working fine.

Thanks for your response.

Cheers

Hi Phani,

Undeploy ur dc from visual admin & redeploy . if that doesn't help, restart ur server but make sure all dependent dc's are deployed already.

regards
