renderOnLoadJavascript being called multiple times
--------------------------------------------------
Key: WICKET-1563
URL: https://issues.apache.org/jira/browse/WICKET-1563
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.3
Reporter: Carlos Pita
There are at least of couple of common scenarios where this happens:
- you add the component that is a header contributor to an ajax target:
renderHead is called as part of target.respond() and latter by page.detach()
- you add the component that is a header contributor more than once to an ajax
target. Normally you can't control this, because the component in question is
added by another component indirectly, by adding some of its ancestors.
renderHead is called multiple times as part of target.respond() and latter yet
another time by page.detach()
I think there must be a check to avoid repetitions of these nature, maybe by
means of an id, the same as renderJavascript() does.
