AjaxIndicatorAppender.renderHead does not pass Components id in its call of
renderJavaScript
---------------------------------------------------------------------------------------------
Key: WICKET-4096
URL: https://issues.apache.org/jira/browse/WICKET-4096
Project: Wicket
Issue Type: Bug
Components: wicket-extensions
Affects Versions: 1.5.0
Environment: Windows 32bit XP, Tomcat 7, java6 and scala 2.9.1, build
with Eclipse
Reporter: Marcus Bosten
Priority: Minor
In an AjaxEditalbeLabel we set an int - that will reload a dataview with number
of lines as given in the AjaxEditingLabel.
In that dataview we use IndicatingAjaxLink to sort the columns. With Wicket
1.4.18 that worked well.
With Wicket 1.5.0 in this scenario, if the AjaxEditalbeLabels onSubmit(...)
Method is called, an error occurred:
Root cause:
java.lang.IllegalArgumentException: Argument 'id' may not be null.
at org.apache.wicket.util.lang.Args.notNull(Args.java:39)

org.odlabs.wiquery.core.AbstractWiQueryDecoratingHeaderResponse.renderJavaScript(AbstractWiQueryDecoratingHeaderResponse.java:128)

org.apache.wicket.extensions.ajax.markup.html.AjaxIndicatorAppender.renderHead(AjaxIndicatorAppender.java:71)

We found that the AjaxIndicatorAppender.renderHead calls the
org.odlabs.wiquery.core.AbstractWiQueryDecoratingHeaderResponse.renderJavaScript(someJavaScript,
null)
The method renderJavaScript expicitly checks if the second parameter is null
and throws an Error here.
Imho the AjaxIndicatorAppender.renderHead should pass the components id instead
of the null.
By the way: Wicket rocks anyway, but 1.5 is another Highlight!
Thanks a lot and best Regards,
Marcus Bosten
