Re: renderHead() / wicket:head page / component order

 But one more question though : why rendering wicket:head (in the markup

 Seems to me that what you'll put in wicket:head will certainly be some
 king of static code, like the css in my problem (so like this :
 .myclass{ padding: 0;} or $(document).ready(function(){
 $(#login).focus();});). This code could need some library (JQuery for
 exemple), and you'll serve that resource using a ResourceReference so
 using renderHead() right ? If wicket:head is served before renderHead()
 then you'll have a problem...

With these things you just have to make a decision. Both orders are equally 
valid. You use wicket:head for minor adjustments in styling, others use 
wicket:head to contribute the css files and do the adjustments in renderHead. 
The idea was, that with this order, it is always possible to override any 
static wicket:head contribution from the Java code. Personally, I try to avoid 
wicket:head as much as possible and render everything from renderHead. This 
gives you the most flexibility.

Emond

Re: DataTable's accessibility use of the id and headers attributes to table cells so screen readers can identify the cells that relate to the headers for blind people

2012-07-31 Thread Martin Grigorov
Hi,

Most of the default components do not support well ARIA or similar
accessibility specifications.
Patches are welcome, as always!

 Hey guys,



 I've noticed during a scan of our webapp in http://achecker.ca that the
 Wicket DataTables do not quite support accessibility when it comes to
 mapping its table cells to the table headers via the TD element's ID and
 HEADERS attributes. Is that true or am I using the wrong component?



 I'm just asking before I start overriding methods from the DataTable to
 implement this.

 And if I do this, shouldn't I submit a patch back to you guys?



 To see what I'm talking about, simply take any of the HTML source code of a
 Wicket DataTable with more than one row in it and with a HeadersToolbar and
 then scan it via http://achecker.ca and notice the errors and suggestions
 given:

Editing list in Dataview

2012-07-31 Thread kshitiz
Hi,

Right now I am using listview but I am considering to look after dataview
where data is fetched from database everytime you change page. So, do we
have to modify our query to get the required data to be displayed in the
page? I mean right now I am  retrieving all data from database. 

Also, will it be possible for me to update the list being displayed in a
page like deleting a content or rearranging them?

Re: Link is disabled after Ajax request

2012-07-31 Thread Martin Grigorov
Hi,

On Mon, Jul 30, 2012 at 5:09 PM, tmaus loum...@yahoo.com wrote:
 Hi there ..

 Setup a panel that covers both, a facebook-login button and a user state
 sensitive link.

 The link should be disabled unless we find a user in the session.

 The Ajax FB link looks like:

 AjaxLink fbLink = new AjaxLink(fb) {
 public void onClick(AjaxRequestTarget target) {


 getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(new
 RedirectRequestHandler(http://www.facebook.com/login.php?api_key=; +
 pcs.getFbApiKey() + v=1.0));
 }
 };
 add(fbLink).setEnabled(session.getAttribute(user) == null);

 It works like a charm.


 The link looks like:
 adminPageLink = new Link(adminLink,model) {
 public void onClick() {
 setResponsePage(new HomeAdminPage());
 }

 protected void onConfigure() {
 LOG.debug(onConfigure);

Is this debug statement logged after FB returns ?
Also add the value of session.getAttribute(user) in the log message.

 setVisible(session.getAttribute(user) != null);
 }
 };

 add(adminPageLink);

When you update an invisible component in an Ajax request you should
also do: invisibleComponent.setOutputMarkupPlaceholder(true)
Check the javadoc of this method for more details.
But I think the second render (after FB returns) the request is not
Ajax anymore, so this shouldn't be necessary.



 This link is properly rendered as long as the FB login page has not been
 called and returned.

 Once the user is properly logged into FB, the adminLink is not clickable (no
 tag is rendered)

 Im still quite new to Wicket and any help your be appreciated.

 Best regards

 Thorsten

Re: Link is disabled after Ajax request

2012-07-31 Thread tmaus
Thanks for your response, Martin ...

I have tried to tweak things a bit, replace the Link by an AjaxLink,
overrode internal methods and did some things things. 

The fb login button as well as the link to me admin area belong to a panel. 
The fb login button fires an async call to fb. 

The link is always visible on first page rendering. 
The link is always disabled after response from fb. 

This must be related to the Panel where both components reside in. 
No matter if the fb button is a simple Link or an AjaxLink, the callback
from fb somehow disables the link within the panel. 

An outside of the Panel located Link is not disabled. 

Any hint why this happens or any links to docs that explain this behavior
are much appreciated ..

Re: Link is disabled after Ajax request

2012-07-31 Thread tmaus
I see all log statements. 
All methods are properly accessed. 

I tested it both ways: 
1. A static link = complete rerendering of the page
2. AjaxLink = partially rerendering of the page

In both occasions the outcome is the same. 

Initial call renders link properly
Successive call renders link as label 

The funny thing about it is, that my FB button properly switches between the
states:

public class MenuBarPanel extends Panel
...

public MenuBarPanel(String id,Page page, IModel model) {
super(id);
this.page = page;

final Session session = page.getSession();

setOutputMarkupId(true);


AjaxLink fbLink = new AjaxLink(fb) {
public void onClick(AjaxRequestTarget target) {
LOG.debug(button clicked);

   
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(new
RedirectRequestHandler(http://www.facebook.com/login.php?api_key=; +
pcs.getFbApiKey() + v=1.0));
}
};
add(fbLink).setEnabled(session.getAttribute(user) == null);

String fbImage = null;
if(session.getAttribute(user)!=null){
fbImage = new StringBuilder(https://graph.facebook.com/;)
.append( ((User)
page.getSession().getAttribute(user)).getFacebookId())
.append(/picture)
.toString();

}else{
fbImage = http://www.lamptechs.com/svcimg/login.png;;
}
fbLink.add(new StaticImage(image, new Model(fbImage)));

adminPageLink = new AdminLink(adminLink, model);
adminPageLink.setOutputMarkupId(true);
add(adminPageLink);

 private class AdminLink extends AjaxLinkHomeAdminPage{
private IModel model;

public AdminLink(String id, IModel model) {
super(id, model);
}

public void onClick(AjaxRequestTarget target) {
setResponsePage(new HomeAdminPage());
}
}

On initial call, login button is rendered. On the successive call it
properly renders my picture.

The AdminLink however is merely properly rendered on the initial call. 

Im pretty sure it is a typical beginners bug but I did not find any answer
in any forum so far .. 

thanks for your help

ComponentNotFoundException when replace a fragment

2012-07-31 Thread Alex66955
Hey,

I have some issues when I replace a fragment in an ajax calback function.
There is a parent class and a child class. The parent create an
AbstractAjaxTimerBehavior and call in it the fragment with the child class.
In the child class there is also an AbstractAjaxTimerBehavior to process
some data to show. When I replace in the parent class ajax callback function
the fragment, I get the follow exception ComponentNotFoundException. 

I think the child ajax request search for the right component, but the
component is replaced. How can I tell wicket that the component is no more
valid or something else.

My stack trace:






Best regards

Alex

No. This just starts a panel, i.e. render it.
There is nothing about form submittion in this line of code.

RE: Where to add javascript in html pages which follow inheritance relationship.

2012-07-31 Thread Paul Bors
From what I remember wicket:head/ is the way to go!
https://cwiki.apache.org/WICKET/wickets-xhtml-tags.html#Wicket%2527sXHTMLtag
s-Elementwicket%253Ahead

I believe this tag will appends what its surrounding to the bottom of
already existing head tag contents on the page.

For your child page you should not define another head html tag inside
wicket:head. View your page source and start troubleshooting from there.

And if you didn't define another head html tag, then post your code so we
can better help you better :)
