Did anybody try to run my attached quickstart application and can explain why
the additional LocaleMapper changes the path?

Re: Wicket localization in stateful pages

[meduolis]

Storing it in page will not work as it will reset each time I call
setResponsePage.
Storing it in data base will not work also, because locale will became
global for all visitors.
So I tried to pass it using page parameters. Also, I have updated dynamic
label model to LoadableDetachableModel.

This time I got different result, but still, not what I expected.

"Back" action restores locale from page parameter one step behind the value
stored in session,
so I got different values each time I go back.
Attaching updated version, if there is still someone who will to help me:
versionLocale.zip

Hey,

For a simple solution just overwrite onComponentTag().
But I think there a already complete components addressing this issue.

   @Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
if (getPage().getPageClass() == Fault.class) {
// inline style
tag.put("style", "color: red;");
// css class
tag.put("class", "active");
}
}

Hello,

there are 4 links at the top of my page.
[cid:eda0a64b-ce32-4c04-b1b1-cc10df635636]
Every link should forward to another page. But the User couldn't see on which 
page he is. I want to change the color of the links depending on the page which 
the user has chosen. How can I realize this? I implemented the links like this:

Link faultLink = new Link("faultLink") {
@Override
public void onClick() {
setResponsePage(Fault.class);
}
};

Re: Wicket localization in stateful pages

[Sven Meier]

Is there a way to restore locale for dynamic models when navigating between 
page versions?


Whenever the locale is changed, put it in the session and store it in the page 
too.
Override #getLocale() and return whatever is stored as the page's locale.

Ok, I will be more specific:

static and dynamic models) updates to english);
*action 2.* I click link switchLanguageToDE; (VERSION 2)(... updates to
german);
*action 3.* I click back in browser; (VERSION 1) (label with static model
updates to english, dynamic - stays german).

debug result:
Static model: getSession().getLocale() == en EN (locale restored from

Dynamic model: getSession().getLocale() == de DE (locale taken from version
2)

My last question related to this topic (sorry for that spam):

Re: Get return value of ajax event in Wicket 6.9.1

[Martin Grigorov]

There is a difference between onunload and onbeforeunload. You can cancel
the latter.
You can make Ajax call only in onbeforeunload. And it has to be synchronous.

Re: Wicket localization in stateful pages

[Martin Grigorov]

Hi meduolis,

I hope you know what http session is.
It doesn't matter how you get to a page (via a normal (forward) link or via
back button), when you read an attribute value from the session it will be
the same.

In your case the dynamic models use the session's locale to decide which
i18n resource bundle to use.

Re: Get return value of ajax event in Wicket 6.9.1

[Cedric Gatay]

AFAIK the browser won't issue a new server call (or will not process the
response) once the onunload event has been called so I doubt this will work
(using the web inspector of your browser will allow you to check whether or
not the call has been done)

I second what Martin said, you need to add the JavaScript code to call the
server.

Re: Wicket localization in stateful pages

[meduolis]

Hi Martin,

so, if I want "browser back" action to show the same result, I have to
choose between components with static models or components with dynamic
models only? Because if I use different types I will get different results
when backing to older page version? 
I am really not getting the thing here :). Shouldn't it be consistent?

Re: Get return value of ajax event in Wicket 6.9.1

[Martin Grigorov]

respond() is the callback method that Wicket will notify.
But you need to trigger an Ajax call first. This is done with the Wicket
Ajax API: Wicket.Ajax.get(...).

Just try with the line I've added in your JS code

Re: Get return value of ajax event in Wicket 6.9.1

[Daniela L]

Ok thanks.

I did the same like this:
Link faultLink = new Link("faultLink") {
@Override
public void onClick() {
setResponsePage(Fault.class);
}
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
if (pageName.equals(Fault.class.getSimpleName())){
tag.put("class", pageName);
}
}
};

You want to give a different CSS for links in different pages?

public class ClassModifier extends AttributeModifier {

/**
 * @param attribute
 * @param replaceModel
 */
public ClassModifier(IModel replaceModel) {
super("class", replaceModel);
}

/**
 * @param attribute
 * @param value
 */
public ClassModifier(Serializable value) {
super("class", value);
}

}

and

faultLink.add(new ClassModifier(this.getClass().getSimpleName()) )

?

Re: Get return value of ajax event in Wicket 6.9.1

[Daniela L]

Hi,

I have tryed to change to AbstractDefaultAjaxBehavior like I described
below, but respond is never called. What am I doing wrong?


Hi,

as far as I have understood this can only be achieved, if I subclass
AbstractDefaultAjaxBehavior like this?

public class PageExitWarningBehavior extends AbstractDefaultAjaxBehavior  {
@Override
protected void respond(AjaxRequestTarget target) {
AppointmentSession.get().releaseSavedBlockedFreeCalendarEvent();
  }


Hi,

You need to make an Ajax call to the server.

Get return value of ajax event in Wicket 6.9.1

[Daniela L]

Hi,
this is my first question, so i hope I get everything right.

I am trying to catch the event of the user closing the browser window in
wicket.

I followed this example:

http://stackoverflow.com/questions/16527463/call-java-component-from-javascript-and-retreive-value

and I managed to get the example working so the message is displayed, but I
have no idea how to get the event triggered by the javascript function in
wicket. I need this because when the user closes the browser window I want
to update some data in my database.
Here is what I have tryed:


 RequiredTextField myTextField = new
RequiredTextField("myTextField");
 myTextField.setOutputMarkupPlaceholderTag(true);
 myTextField.add(new PageExitWarningBehavior(){
@Override
public void onEvent(Component component, IEvent event)
{
//this isn't ever called
MySession.get().releaseBlockedDataFromDatabase();
}
});

public class PageExitWarningBehavior extends Behavior  {
@Override
public void renderHead(Component component, IHeaderResponse
response) {
super.renderHead(component, response);
response.render(new
OnDomReadyHeaderItem("window.onbeforeunload = function (e) {"
  + "var message = 'Your confirmation message goes here.',"
  + "e = e || window.event;" + "if (e) {"
  + "e.returnValue = message;" + "}" + "return message;" +
"};"));
}
}

What am I missing? Thank you very much in advance :-)

SV: Table row visibility

[Tron Walseth]

Hi again

I wanted to turn on/off row visibility, and in doing that, I wanted to set row 
id on the row. 

I found out how this should be done, in overriding the newRowItem on the 
DefaultDataTable class, and adding an AttributeModifier to the rowItem. 

Sorry for any inconvenience. 

Yours,

If this is all your Java code then you better use BookmarkablePageLink. It

Re: Handler after jqXhR success et before ajax response proccess

[Olivier Dutrieux]

thx for your response Martin,

Maybe a handler in the IAjaxCallListener (between jqXHR.success and Ajax
response is process) will be very nice feature in the future version of
wicket :)

Hello,

I was already trying this. But it didn't works. Here is HTML:
ESB Fehler | Protokollierung  | Benutzerverwaltung | Passwort ändern

And here the Java:
Link faultLink = new Link("faultLink") {
 @Override
 public void onClick() {
setResponsePage(Fault.class);
 }
};
faultLink.setAutoEnable(true);

These links are in my parent page. The FaultPage extends of my parent page. 
Could that be the problem?

Maybe use CSS? Add a class attribute with the "name" of the page?

[Christoph.Manig]

Hello,

there are 4 links at the top of my page.

Every link should forward to another page. But the User couldn't see on which 
page he is. I want to change the color of the links depending on the page which 
the user has chosen. How can I realize this? I implemented the links like this:

Link faultLink = new Link("faultLink") {
@Override
public void onClick() {
setResponsePage(Fault.class);
}
};

Table row visibility

[Tron Walseth]

Hi, 

I have a table with legends explaining map (OpenLayers) layers. 
I want to turn visibility on/off on the entire row based on the visibility of 
these map layers using JS. 

I can easily turn on/off the visibility of the legend image itself using 
JavaScript/JQuery, but I want to toggle visibility of the entire row. I know 
this can be done through ajax, but I don't want to put extra unnecessary load 
on the server through Ajax calls. 

The easiest way to do this (AFAIK) is adding an id to the table row, and 
toggling visibility through JQuery: 

$("#tableRowId").show()/hide();

Below is the entire code of my LegendPanel pasted. 

Yours, 
Tron Walseth

public class LegendPanel extends MapPanel
{
private static final long serialVersionUID = 1L;
/**
 * @param id
 */
public LegendPanel(String id, List layers, 
BusinessDataAjaxMap map)
{
super(id, map);
ListDataProvider dp = new ListDataProvider<>(layers);
DefaultDataTable table = new 
DefaultDataTable<>("legends", getTableColumns(), dp, 10);
add(table);

}

private static List> getTableColumns()
{
List> cols = new ArrayList<>();
cols.add(new HeaderlessColumn() {

private static final long serialVersionUID = 1L;

@Override
public void populateItem(Item> 
cellItem, String componentId, IModel rowModel)
{
cellItem.add(new Label(componentId, 
rowModel.getObject().getLegendDescription()));
}});
cols.add(new HeaderlessColumn() {
private static final long serialVersionUID = 1L;

@Override
public void populateItem(Item> 
cellItem, String componentId, IModel rowModel)
{
Url imgUrl = 
Url.parse(rowModel.getObject().getLayerLegend().trim());
ResourceReference ref = new UrlResourceReference(imgUrl);
ImagePanel i = new ImagePanel(componentId, ref);
i.setMarkupId(rowModel.getObject().getLegendDescription());
cellItem.add(i);
}
});

return cols;
}

Re: Efficient pagination with MongoDB and Wicket

[Martin Grigorov]

Hi,

You can create MongoDataProvider that will implement #iterator(start,
count) but will ignore the passed parameters.
You will need additionally to create your own PagingNavigator with custom
links which when clicked would do something like:
mongoDataProvider.setFirst(someObjectId) and
mongoDataProvider.setRange(whatEverIsNeeded). Then #iterator() and #size()
will use the start ObjectId and the Range to do whatever is needed.

I see that you will need to provide custom impls of several Wicket
interfaces/classes to make them more optimal for Mongo. You can donate them
as WicketSuff project [1] so other people can reuse and optimize them.

Yes, this should work.
Set 'wr' to false then create a new instance of Wicket.Ajax and call
processAjaxResponse() on it with all the required parameters.

Another option is to set some custom attribute to the div in beforeSend().
Then in success() you can check whether this custom attribute is still
there and decide what to do depending on this information.

Re: Wicket localization in stateful pages

[Martin Grigorov]

Hi,

As Sven explained "2. new Label("contentNoModel",
resolveLocalizedContent());" doesn't use dynamic model (a model that will
re-calculate its object/value on each request). It initializes the value of
the label at construction time and from there on this value doesn't change.
See

we will vote which experimental modules to become non-experimental for

I guess we will do the vote in dev@ mailing list. Probably we should create

Re: Wicket localization in stateful pages

[Sven Meier]

The back-button brings you back to the previous state of the component tree.

If your page is depending on external state (e.g. session or database 
content) for rendering, it will of course show the most recent data 
wherever you have told it so (by using a model).

Should I override "back" action somehow and do it myself?
