wicket-dnd strange situation

[Decebal Suiu]

Hi

I use wicket-dnd (0.5.0) with wicket 1.5.5. Initial I developed a small application with these libraries but now I want to integrate the code in a big application (copy/paste with some rename on packages).

In the big application I retrieves "Uncaught TypeError: Object #<HTMLDocument> has no method 'ready'" in firebug.

In the generated html I see some differences:
<script type="text/javascript"> /*<![CDATA[*/ $(document).ready(function(event){new wicketdnd.DropTarget('id11','pivot?13-2.IBehaviorListener.1-areas-area-1',['MOVE'],[''],'undefined','undefined','div.value-container','undefined','div.value-container');}); /*]]>*/ </script>in the big application

and
<script type="text/javascript"> /*<![CDATA[*/ Wicket.Event.add(window, "domready", function(event) { new wicketdnd.DropTarget('id11','?0-1.IBehaviorListener.2-areas-area-1',['MOVE'],[''],'div.value-container','undefined','undefined','undefined','undefined');;}); /*]]>*/ </script>in the small application

My html head looks (the strip version):
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script><script type="text/javascript" src="../js/bootstrap.js"></script><script type="text/javascript" src="./wicket/resource/org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow/res/modal-ver-1338386033000.js"></script><link rel="stylesheet" type="text/css" href="./wicket/resource/org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow/res/modal-ver-1338386033000.css">
<script type="text/javascript" src="./wicket/resource/org.apache.wicket.markup.html.WicketEventReference/wicket-event-ver-1338385910000.js"></script><script type="text/javascript" src="./wicket/resource/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax-ver-1338385910000.js"></script><script type="text/javascript" src="./wicket/resource/org.apache.wicket.ajax.AbstractDefaultAjaxBehavior/wicket-ajax-debug-ver-1338385910000.js"></script><script type="text/javascript" src="./wicket/resource/org.wicketstuff.jslibraries.JSReference/js/prototype-1.7-ver-1315885779000.js"></script><script type="text/javascript" src="./wicket/resource/wicketdnd.Transfer/wicket-dnd-ver-1316016245000.js"></script><link rel="stylesheet" type="text/css" href="./wicket/resource/wicketdnd.theme.WebTheme/web/theme-ver-1316016245000.css">

Can somebody explain me why these differences happen?

Thanks,
Decebal

Wicket.Event.add(window, "domready", function(event) { new wicketdnd.DropTarget(...) }); // works

$(document).ready(function(event){new wicketdnd.DropTarget(...)}); // error (probably jquery not found or a conflict between jquery and prototype)

[Sven Meier]

Are you using wiquery?

I remember an incompatibility between prototype and jquery in that case.

Hello Sven

First, I want to say thanks for your contribution to wicket (for wicket-tree and wicket-dnd in special).

Yes, I use wiquery :) I read http://code.google.com/p/wicket-dnd/issues/detail?id=13&can=1.
Is there anyone from wiquery that can explains us why wiquery doesn't works with wicket-dnd?

And a question from Sven: it is possible to use jquery instead prototype to implement wicket-dnd (I think that jquery is "embedded" in wicket core from version 6)?

Thanks,
Decebal

[Sven Meier]

For Wicket 6 I'll port wicket-dnd to jquery.

Nice. I see a beautiful future :) wicket-dnd integrated with wicket tree and of course wicket-dnd part of wicket core.
Now, I'm waiting a clarification from a member of wiquery.

Thanks again,
Decebal

hi

Prototype uses $ like jQuery. That can create conflict (your error message
indicates that the jquery method "ready" is not available. probably vecause
Prototype was loaded after jquery and so override $.).

jquery offers a noconflict mode, but I don't remember if we have integrate
it to wiquery (like an option).

in all cases it is not a good idea to mix many javascript core apis. so use
jquery only or prototype, but not the twice in the same time.

regards

Hi Julien

Thanks for the fast response. Sven says that for wicket 6, wicket-dnd will be port to jquery but now I see that I have only one option: to give up one library (wiquery or wicket-dnd). Both libraries are very good and I want to keep both.

Is it a chance to activate jquery no conflict mode in wiquery? Other advice is welcome.

Thanks
Decebal

Another technical question is who (I suppose wiquery) and why change

Wicket.Event.add(window, "domready", function(event) { new wicketdnd.DropTarget(...) });

in

$(document).ready(function(event){new wicketdnd.DropTarget(...)});

Best regards, Decebal

Hi Decebal,

Sorry for the late response but I was on holiday.

The 2 code snippets below do exactly the same. They look different but they both perform "new wicketdnd.DropTarget(...)" when the dom is loaded and ready. Can you provide a better/bigger example?

I checked your other posts and saw a link to a bug report. In this you say you use WiQuery for the modalwindows but WiQuery has no support for them as Wicket already provides this.

Regards,
Hielke

Hi Hielke

First, I want to say thanks for wiquery. I integrated wiquery in a big project with success and we are happy with them.

I know that the 2 code snippets do exactly the same. The first uses the wicket mechanism and the second uses the jquery mechanism. I read at http://code.google.com/p/wicket-dnd/issues/detail?id=13#c1 that "WiQueryCoreInitializer(hooked up via WiQueryInitializer) installs its custom WiQueryDecoratingHeaderResponse" and I suppose that WiQueryDecoratingHeaderResponse translate the first code snippet in the second.
In my case the problem is "$" jquery variable instead "$.noConflict()" (we need to use another JavaScript library - prototype from wicekt-dnd - alongside jQuery).

Probably a jquery layer in the wicket core will help more the wicket developers that consume jquery (core, ui) and the projects that integrate wicket with jquery. In this layer I see a standard mode to add jquery.js, some behaviors that add jquery core functions in wicket and also different kinds of helpers (options) for function parameters (boolean, string, ....)

Best regards,
Decebal

Dear Sven,

Is wicket-dnd already changed for wicket 6 ?
I can't find the sources for this..

Thanks! Kind Regards, Marieke Vandamme

[Sven Meier]

That's still on my TODO list.
