domready events not always fired in IE
--------------------------------------
Key: WICKET-4080
URL: https://issues.apache.org/jira/browse/WICKET-4080
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.5.1
Reporter: Emond Papegaaij
Attachments: dom-ready-ie-fix.patch
The domready events for IE rely on a onreadystatechange to state 'complete'.
Normally, this state should go from 'loading', to 'complete' to 'loaded'.
However, IE does not always trigger events for all states. Why it skips certain
events, I don't know, but it seems related to other content being loaded at the
same time. Perhaps IE does not find the time to trigger the event and simply
skips a step. If it skips 'loading' or 'loaded', there is no problem, but if it
skips 'complete', the domready scripts will never run. I've never seen it skip
more than one state, therefore I propose the attached patch, which also checks
for 'loaded'.
Although nothing has changed for a long time in wrt domready, this now is a
serious issue when using the latest version of wiquery. The reason is that
wiquery changes the order in which javascript files are added to head, and this
different order causes IE to skip states far more frequently.
