Martin Grigorov commented on WICKET-4305:
-----------------------------------------
Check the "Subversion commits" tab here to see how I did it in Wicket 6.0. The
change revision is r1221193.
If you like it and want it in Wicket 1.5 please port it and attach the patch
here. There are minor differences in the .js part.
> Problems with AbstractAutoCompleteBehavior on BookmarkablePages
> ---------------------------------------------------------------
>
> 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
>
> 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);
> }
