If async IOC is active, the callback will be invoked asynchronously (at least 
when it first downloads the source for the corresponding bean). You can take a 
look at the new ListWidget implementation which needs to wait until all 
callbacks have been executed as well:
https://github.com/errai/errai/blob/master/errai-ui/src/main/java/org/jboss/errai/ui/client/widget/ListWidget.java

Another option is to make use of the InitVotes system:
https://github.com/errai/errai/blob/master/errai-common/src/main/java/org/jboss/errai/common/client/api/extension/InitVotes.java

This is unfortunate but there seems to be no way around it when supporting 
async bean management.

Cheers,
