Can't reference DC

[Former Member]

Greetings, SDN members.

I am having troubles referencing DC in other DC (in NWDS).

• I have exposed the WebDynpro component (let's call it A) in public part of DC metadata

• I have created several methods in component interface controller of controller A

I cannot add the component A to component B as when I go to controller or "Used Web Dynpro Components" in component B and click "Add Used Component", component A doesn't appear in the wizard.

Could anyone guide me in how to reference one DC in another correctly?

Hi Ivan,

Is your public part of type "COMPILATION"?

Have you done a complete rebuild of DC A with "Development Component" --> "Build"?

Have you declared a dependeny to DC B in the Component Properties of DC A?

Greetings,

Yes, the PP is of type "compilation", and I have tried different dependencies between components when trying to reference them. And yes, I do a full re-build each time I change anything, as the framework sometimes behaves strangely...

Can you think of anything I could do more?

Hi

Before adding the component A in used component section of DC B, you need to add DC A as used DC in DC B.

Follow the below mentioned steps

1. Expand the project structure for DC B.

2. Go to DC Metadata-> DC Definitions-> Used DC's

3. Right click and sleect Add Used DC..

4. Follow the screens to add DC A as used DC in DC B.

5. Rebuuild the project.

Then try to add component A in used component section.

hope this helps you.

Hi Amit,

This is the most basic procedure that I did perform in the first place.

I am probably missing some setting in the DC, or it might be a problem with NWDS as it missing in the wizard (the popup window).

Do you have any additional ideas?

Regards,

Ivan.
