Error: missing component

Hello,

I am trying to modify the MSS webdynpro application ess_usfam. I have NWDI installed and configured correctly. I hvae created a project over the ess_usfam development component but when I go into NWDS and look at the project I have an error under the "Used Web Dynpro Components" area for several of the WebDYnpro components. The error is - FcPersInfo <Error: missing component>

Also, there are a few other errors that seem to be source code related such as there are some Begda and Endda context fields that have no "Type" attribute set.

Thanks everyone,

Bert
