> Key: WICKET-4305
> URL: https://issues.apache.org/jira/browse/WICKET-4305
> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 1.5.3
> Reporter: Daniel Peters
> Assignee: Martin Grigorov
> Fix For: 6.0.0
>
>
> AbstractAutoCompleteBehavior internally uses the GET parameter "q".
> If you are on a bookmarkable page that also uses the parameter q (very common
> for searches), AutoCompleteTextFields wont work anymore. They will only see
> the original q parameter that has been used to call the page.
> The autocomplete appends the q= param to the URL and read it with
> getParameter("q"). Since there are 2 params with the same name now, it will
> always get the first.
> My first fix was to rename the autocomplete parameter to something like
> "wicketac:q", but this breaks WicketStuff-objectautocomplete which uses the
> same JS, so this is probably not a good idea.
> Another idea was to get the _last_ q-parameter of the URL in
> AbstractAutoCompleteBehavior.
> This works quite well...
> Code:
> protected void respond(final AjaxRequestTarget target)
> {
> final RequestCycle requestCycle = RequestCycle.get();
> final List<StringValue> values =
> requestCycle.getRequest().getRequestParameters()
> .getParameterValues("q");
> final String val = (values != null && values.size() > 0) ?
> values.get(values.size() - 1)
> .toOptionalString() : null;
> onRequest(val, requestCycle);
> }
