RestDataSource queuing

[hkhung]

Hi,

I am using RestDataSource with Grails. However, I saw that some DSRequests are merged and queued by default. However, my current Grails code cannot handle it.

1. Is there any way to disable queueing? I can't find any information from docs.
2. Is the response format (xml) different between queued and non-queued response?

[Isomorphic]

All covered in the RestDataSource JavaDoc.

I cannot find anything about disable queuing in the Java Doc
http://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/data/RestDataSource.html

I cannot get queuing work for RestDataSource.
