Re: Question about $ref statement processing

[Markus Sabadello]

Ning, this looks like a bug in the server, I documented it and will fix in the next release:
https://github.com/projectdanube/xdi2/issues/42

For now yes it seems a workaround is to send separate message envelopes.

You should be able to send the $del in one envelope, and then the two $set messages together in a separate message envelope.

This way at least you can send all the $set operations in a single message envelope.

Hmm this should work, can you show the exact message envelope you're sending?

Markus,

I have the following statements sent to the graph server in a single MessageEvelope:

=!:uuid:9999#profile$card#address/$ref/=!:uuid:9999#address

=!:uund:9999#profile$card#address<#country>/&/"USA"

Each statement has its own ordered Message within the 

But the graph server an exception such as:

Cannot add <#country> context node to context node =!:uuid:9999#profile$card#address containing a $ref relation.

The workaround seems to be sending two separate messages.

I am wondering if there are better way to do this.

Thanks,
