web dynpro component interface, can't create a instance

[Former Member]

Hi guru,

I have created a web dynpro component interface, and implemented it through some components.

But when I use the interface in another component, there comes a runtime error. The following is the error message.

Error when Creating Component YHREFM_OBJSEL_INTERFACE. YHREFM_OBJSEL_INTERFACE Is a Component Interface, Therefore, an Instance Cannot Be Created. Name of Component May Not Be Specified. (Using Component: YHREFM_PRINT_FORM_SE, Component Usage: USAGE1)

Need your help!

I changed the usage name from 'USAGE1' to a new name. And now it works

Hi,

I have found the cause of the problem. I have mapped some context in the component interface to componenet_A. Then I active component_A, and test it. Then the exception on the top of the Thread is raised.

What's wrong with it? Could someone give me a solution?

Thank you very very much.
