Eclipse ADT "Code information is not available"

[DamianKolasa]

Hi,

When building CDS view, code completion retrieves possible entries but fails each time when accessing documentation:

Double click on message (empty, marked above) gives:

java.lang.NullPointerException
	at com.sap.adt.cds.common.annotation.service.AnnotationCodeElementInfoService.getDdlaElementInfo(AnnotationCodeElementInfoService.java:118)
	at com.sap.adt.cds.common.annotation.service.AnnotationCodeElementInfoService.getDdlaElementInfo(AnnotationCodeElementInfoService.java:107)

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

At first I though that something is wrong with backend configuration, however quick look at SICF shows no problems:

When I test these services they work, I can get information about CDS' tags and values...

I also checked ST01 traces and SMICM trace file - no errors there (at least not for my user).

I'm using latest releases of eclipse and ADT:

• Eclipse 2021-06 (4.20.0)
• ADT 3.18.1 (from https://tools.hana.ondemand.com/latest)

Regards,

Damian

Your backend system does not yet support "Code Element Information" for Annotations. The nullpointer exception will get fixed in one of the next ADT versions.
