Ronald Cruz created WICKET-6840:
-----------------------------------
Summary: Busy indicator persists after request
Key: WICKET-6840
URL: https://issues.apache.org/jira/browse/WICKET-6840
Project: Wicket
Issue Type: Bug
Components: wicket-core, wicket-extensions
Affects Versions: 9.0.0, 9.1.0
Environment: Linux - Ubuntu 19.10 and centOS. Using OpenJDK 14.
Reporter: Ronald Cruz
Attachments: test_project.zip
The busy indicator (implementations of `IAjaxIndicatorAware`) appears to
persist after the AJAX request finishes. To be precise, It looks like it's not
being properly cleaned up, as subsequent requests continue to add new
indicators to the page. This looks to be new in Wicket 9/9.1, as I didn't
observe the behavior in the past (Wicket 7/8) out of the box.
I've seen this occur with uses of `IndicatingAjaxLink.java` along with
ModalWindow/ModalDialog, but also for use cases of the vanilla
`AjaxIndicatorAppender` behavior attached to a component.
I've attached a small quickstart project which should hopefully make this easy
to reproduce. It should suffice to start the project and click any of the two
links present.
