[jira] [Comment Edited] (ISIS-915) Using ViewModel annotations creates exception in wicket viewer

["Dan Haywood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ISIS-915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14159044#comment-14159044 ]

-----------------------------------------------------------

This is because Address is referring to Street, both view models.  We currently don't - transparently - support this use case.

The fix would be to make MementoService more sophisticated.  The memento string you see is actually a base64-encoded version of an XML document.  So that XML could in principal be arbitrarily complex, and thus could embed the state of the referenced ViewModel.

The snag is the right now we don't have a way for framework-provided services annotated with @DomainService to be replaced.  But I intend to address that for 1.7.0.

I'm going to update this issue with the actual requirement for the framework to transparently support view models referencing other view models.

could you upload the complete stacktrace?
