Summary: Wicket-atmosphere pushes empty messages
Key: WICKET-5153
URL: https://issues.apache.org/jira/browse/WICKET-5153
Project: Wicket
Issue Type: Bug
Components: wicket-atmosphere
Affects Versions: 6.6.0
Reporter: Andrei Badea
Assignee: Emond Papegaaij
When filters filter out all subscriptions for a page, the logic around the
ajaxRequestScheduled flag in AtmosphereRequestHandler prevents rendering the
AjaxRequestHandler, which results in an emtpy response. This is pushed to the
client and passed to the Wicket Ajax framework, which fails to parse it,
because it expects it to be an XML document with ajax-response root element.
This appears in the Wicket Ajax debug window:
ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Could not find
root <ajax-response> element
Note that because of
https://github.com/Atmosphere/atmosphere/issues/1042
Atmosphere does not pass the first empty message to callbacks, so the error
above only happens when the second empty message is pushed.
