NullPointerException - WebScaffoldMetadata

[obobo]

So far it's my first day with ROO, but I'm totally thrilled to have found it!

Unfortunately, the following simple ROO code (part of a much bigger model) generates an error (NullPointerException at org.springframework.roo.addon.web.mvc.controller.W ebScaffoldMetadata.getCreateFormMethod(WebScaffold Metadata.java:337)) :

create project -topLevelPackage com.sefol.PLESpaces
install jpa -provider HIBERNATE -database HYPERSONIC_IN_MEMORY

new persistent class jpa -name ~.domain.AbstractResource -abstract

new persistent class jpa -name ~.domain.PanelSelection -testAutomatically

add field reference jpa -class ~.domain.AbstractResource -fieldName myPanelSelection -type ~.domain.PanelSelection

add field set jpa -class ~.domain.PanelSelection -fieldName selectedResources -element ~.domain.AbstractResource -mappedBy myPanelSelection -notNull false

new controller automatic -name ~.web.PanelSelectionController -formBackingObject ~.domain.PanelSelection

I can prevent this error by removing the -abstract definition from the definition of AbstractResource... but I can't see why this would matter. Perhaps the day has been a bit long, but I'd appreciate somebody explaining why.

Thanks for reporting this.

I have opened a bug at http://jira.springframework.org/browse/ROO-209 so we can investigate this.
