[jira] [Created] (WICKET-5612) If Wicket JS libs are moved to footer, AbstractAutoCompleteBehavior throws "Uncaught ReferenceError: Wicket is not defined"

Hendy Irawan created WICKET-5612:
------------------------------------

             Summary: If Wicket JS libs are moved to footer, AbstractAutoCompleteBehavior throws "Uncaught ReferenceError: Wicket is not defined"
                 Key: WICKET-5612
                 URL: https://issues.apache.org/jira/browse/WICKET-5612
             Project: Wicket
          Issue Type: Improvement
          Components: wicket
    Affects Versions: 6.15.0
         Environment: wicket-bootstrap
            Reporter: Hendy Irawan
         Attachments: wicketrefe.png

I'm moving all JS libs to footer (using wicket-bootstrap also), which works very well because Wicket's {{ResourceReference}} has {{getDependencies()}} (thanks!! :) ).

However {{AutoCompleteTextField}} is giving JavaScript error, particularly in {{AbstractAutoCompleteBehavior}} here:

{code}
	private void renderAutocompleteHead(final IHeaderResponse response)
	{
		response.render(JavaScriptHeaderItem.forReference(AUTOCOMPLETE_JS));
		final String id = getComponent().getMarkupId();

		String indicatorId = findIndicatorId();
		if (Strings.isEmpty(indicatorId))
		{
			indicatorId = "null";
		}
		else
		{
			indicatorId = "'" + indicatorId + "'";
		}

		String initJS = String.format("new Wicket.AutoComplete('%s','%s',%s,%s);", id,
			getCallbackUrl(), constructSettingsJS(), indicatorId);

		final OnDomReadyHeaderItem onDomReady = OnDomReadyHeaderItem.forScript(initJS);

		response.render(new WrappedHeaderItem(onDomReady));
	}
{code}

Error:

{code}
Uncaught ReferenceError: Wicket is not defined ?3:6
(anonymous function) ?3:6
{code}

Wicket.Event.add(window, "domready", function(event) { new Wicket.AutoComplete('searchTexte','./?3-1.IBehaviorListener.1-navbar-searchForm-searchText',{preselect: false,maxHeight: -1,adjustInputWidth: true,useSmartPositioning: false,useHideShowCoveredIEFix: true,showListOnEmptyInput: false,ignoreBordersWhenPositioning: true,showListOnFocusGain: false,throttleDelay: 300,minInputLength: 1,parameterName: 'q',showCompleteListOnFocusGain: false},null);;});
/*]]>*/
</script>
...
{code}

Suggestion: Change to {{OnLoadHeaderItem}} instead, or a way to make sure the script executes after Wicket libraries are loaded.
