[jira] [Created] (WICKET-6040) DebugBar not serializable exception
Elvis Ciocoiu created WICKET-6040:
-------------------------------------
Summary: DebugBar not serializable exception
Key: WICKET-6040
URL: https://issues.apache.org/jira/browse/WICKET-6040
Project: Wicket
Issue Type: Bug
Components: wicket-devutils
Affects Versions: 6.21.0
Environment: jdk 7, ubuntu
Reporter: Elvis Ciocoiu
After upgrading to 6.21.0 I encountered NotSerializableException when refreshing DebugBar in an ajax event. Martin Grigorov suspects this is related to https://github.com/apache/wicket/commit/562d43ccdd7f305f8ca641817f4b63a07ee8b6a6.
To reproduce this:
1. start the application in development mode
2. override onEvent in Application to refresh the DebugBar
public void onEvent(IEvent<?> event) {
if(event.getPayload() instanceof AjaxRequestTarget) {
AjaxRequestTarget target = (AjaxRequestTarget) event.getPayload();
// if we are in development refresh the debugbar (if exists)
if(getConfigurationType() == RuntimeConfigurationType.DEVELOPMENT) {
Component debugBar = page.get("debugBar");
if(debugBar != null) target.add(debugBar);
}
}
>From stacktrace it seems this is related to org.apache.wicket.ajax.AbstractAjaxResponse$AjaxHtmlHeaderContainer:
