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,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.
