http://wicket.apache.org/learn/examples/ still linking to wicket 5 examples

[lucast]

Dear forum,
I am sure someone has already noticed this but I thought of pointing it out.
I'm trying to get to the latest wicket examples page. My first port of call
was to go to http://wicket.apache.org/learn/examples/ and follow the "live
action" link but it takes me to the
http://www.wicket-library.com/wicket-examples/index.html link which displays
all wicket 5 examples.

I had to google the more up to date page:
http://www.wicket-library.com/wicket-examples-6.0.x/index.html in order to
find it.

Is the above link meant to work that way or should it be pointing to wicket
6 examples?

Thanks in advance,
Lucas

Wicket context menu component

[bronius]

Hello,

I needed context menu component, but surprisingly it does not exit for
current version, so decided to roll my own, even though i have very little
Wicket experience and know absolutely nothing about jquery, so im like that
dog :) 
 

Anyway I managed to get something working like this (maybe it will be
helpful for someone or maybe someone smarter will show me my mistakes):
1. Added https://github.com/sebfz1/wicket-jquery-ui dependency.
2. Chosen to use this jquery plugin:
http://medialize.github.io/jQuery-contextMenu/index.html
3. After spending some time I managed to create Behavior like this:

public class ContextMenuBehavior extends JQueryAbstractBehavior {

private static final long serialVersionUID = 1L;

private String selector;

private List menuItems;

public ContextMenuBehavior(String selector, List menuItems) {
super("contextMenu");
this.selector = selector;
this.menuItems = menuItems;

add(new JavaScriptResourceReference(ContextMenuBehavior.class,
"jquery.ui.position.js"));
add(new JavaScriptResourceReference(ContextMenuBehavior.class,
"jquery.contextMenu.js"));
add(new CssResourceReference(ContextMenuBehavior.class,
"jquery.contextMenu.css"));
}

@Override
protected String $() {
// build menu items for jquery
StringBuilder items = new StringBuilder("items: {");
int nbOfMenuItems = menuItems.size();
for (int i = 0; i < nbOfMenuItems; i++) {
MenuItem menuItem = menuItems.get(i);
items.append("'").append(menuItem.getId()).append("': {name:
'").append(menuItem.getTitle().getObject()).append("', icon:
'").append(menuItem.getIcon()).append("'}");
if (i < nbOfMenuItems - 1) {
items.append(",");
}
}
items.append("}");
return String.format("$(function(){$.contextMenu({selector: '%s',
callback: function(key, options) {var m = 'clicked: ' + key; window.console
&& console.log(m) || alert(m); }, %s});});", selector, items.toString());
}

}

4. $() method just prints jquery context menu initialization stuff from
here: http://medialize.github.io/jQuery-contextMenu/demo.html

5. Now when add this behavior to Page and add div class="userContextMenu" to
html right click on it gives me context menu so its working. Clicking on
menu also shows me simple alert message as it is in callback parameter.

6. So far so good, but now Im interested in how to link this to wicket
component listener. I will put this menu on multiple links, so i would like
to receive both on which link user clicked for context menu and which menu
item he have chosen. How would you implement this? Also am I even on the
right track? Is it good approach? Im sorry if this is stupid question :)

Re: Quick fix for "the dreaded org.hibernate.LazyInitializationException" with WicketTester

[vzog]

I managed to make a similar workaround to enable reopening of session in unit
tests using your approach. I'm using wicket 6.7, hibernate 4 and spring
3.2.2.
please let me know if you have any problem in this configuration
Thanks a lot

Re: AjaxFallbackDefaultDataTable: cell not receiving event after sorting

[dlock]

Hi Sven.
I created a QuickStart as per your suggestion and in the process of writing
it I discovered what the issue was.

Basically the mark-up had an erroneous enclosure tag defined which was
causing the problem.  



**

[table]

   * *



Removing the enclosure tag rectified the problem.  

At least now I know how to create a QuickStart :)

Thanks for you help.
