Session size vs detached models

[Daniel Stoch]

Hi,

In Wicket 1.4 the last page reference is hold in a session (is it in 6.x
also?). So after a request has been processed all components and models
should be detached, so this last page reference should not hold transient
LDM values. Is it true?

When we are using DebugBar with SessionSizeDebugPanel, it displays session
size and totalSize (by SessionTotalSizeModel). Does this totalSize includes
size of object loaded by LDM or it counts all components and models size in
detached state?

Yes. A live instance of the last used page is kept in the http session.
Actually it is a list of page instances.
All instantiated and "touched" pages in a request are saved for faster
retrieval for the next request.

LDM null-yfies its transien field explicitly:
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/model/LoadableDetachableModel.java?source=cc#L104

But if your custom model uses transient that is not null-yfied in
onDetach() then it will be kept alive in the http session.

I have to check what is th difference between size and totalSize, but since
https://issues.apache.org/jira/browse/WICKET-4867 the detachable is
detached before measuring its size.

You mean in detach(), not onDetach() ;)

factory method to create the DataGridView in DataTable

[Dirk Germonpré]

Hello,

I'm using the latest Wicket version (6).

I would like to see a factory method to create the DataGridView
(org.apache.wicket.extensions.markup.html.repeater.data.grid) in DataTable
(org.apache.wicket.extensions.markup.html.repeater.data.table).

I need this to be able to override some methods in the DataGridView.

More concrete: I use a TableTree and want to override methods
getFirstItemObject and getViewSize in AbstractPageableView, a superclass of
the DataGridView, which is used in the DataTable, which is used in the
TableTree.

How should I go about this? Do I have to submit a JIRA issue?

Kind regards,
Dirk Germonpré.

techniques using of Form

[Farrukh SATTOROV]

What is best practices to flexible use of Form: to do external subclass
MyForm, to do as instance MyForm inside Panel constructor or inner class of
MyForm inside Panel class ?

getting values from FormComponentPanel outside form.onSubmit()

[lucast]

Dear forum,

I have implemented a FormComponentPanel as suggested both in the Apache
Wicket Cookbook (chapter 2) and  wicket guide (chapter 12.8)
  .

Before I submit the form, I would like to have the option of adding the
content from FormComponentPanel to a list.

I have made use of AjaxButton and  I have set 
AjaxButton.setDefaultFormProcessing( false).

In order to get value from FormComponentPanel when performing 
form.onSubmit(), one calls FormComponentPanel.getConvertedInput(), which in
turns calls FormComponentPanel.convertInput().

The problem is that if I call FormComponentPanel.getConvertedInput() from
inside AjaxButton.onSubmit(), FormComponentPanel.convertInput() is never
called.

My question is, how can I get the contents from FormComponentPanel using a
AjaxSubmitLink or AjaxButton without having to go via form.onSubmit()?

Is there, perhaps another form component that I could use to achieve my
goal?

Thanks in advance,
Lucas

Hi Farrukh,
>From existing literature (Wicket in Action, Apache wicket Cookbook,  wicket
guide   ), there are a
number of ways you can go about it.

You can put your form in a panel, have a submit once form (to prevent
multiple submits) as template and extend that class. It all depends on what
your needs are.

FormComponentPanels are also very useful.

I'm sure people in this forum have better and more extensive suggestions
than me but at least, that's a starter. 
Both the Apache wicket Cookbook and wicket guide are good starting points
for creating your own best practices.

I hope that helps,
Lucas

understanding looking for wicket:id

[Farrukh SATTOROV]

Hi everyone. I confused when i look to standard wicket heloworld example
and try understanding  snippet of . How
HelloWorld.html works without  while id mainNavigation
located in superclass (WicketExamplePage). Explain to me mechanism of
looking for wicket:id in this case.

Re: understanding looking for wicket:id

[Sven Meier]

With a wicket:id declared in Html markup, a corresponding component with 
the same id has to present as child.


It doesn't matter when the child component is added: in the constructor 
or one of its super constructors (or even later).

This does not have anything to do with markup inheritance.

Hope this helps
Sven

FormComponentPanel.getConvertedInput(), which in turns calls

Not true.

See FormComponentPanel#onEvent() on how to properly process a single 
FormComponent.

[Richter, Marvin]

Why wouldn’t you just use the defaultFormProcessing an add the converted value 
of the FormComponentPanel to the list inside your onSubmit method?

Best,
Marvin

my code work, if by definition each WebPage and Panel must have own markup
?

MyBasePage.java:
public class MyBasePage extends WebPage {

public MyBasePage() {
add(new MyPanel("panel"));
}
}

no MyBasePage.html, i remove it.

SubPage.java:
public class SubPage extends MyBasePage {
 public SubPage() {
}

}

SubPage.html:

Re: understanding looking for wicket:id

[Richter, Marvin]

That is definitely not a good way to do inheritance. This way you force 
everyone who extends from MyBasePage to know that he has to have a tag in his 
markup file with a wicket:id he might not know.

The right way would be to have a markup file for MyBasePage.java and include 
the  tag.

MyBasePage.html

Leaving page after closing modal results in browser pop up

[PDiefent]

Hi,
with the current Wicket 6.13.0 I got a new problem. When leaving a page
after openin a modal window results in a browser pop up where I have to
confirm leaving the page. If I leave the page without opening the modal
window the browser doesn't request a confirmation.

Any suggestions?

Thanks, Peter

Jetty, Wicket and getting live JavaScript changes?

[tertioptus]

I use Jetty, maven and Eclipse.

*What's the best way for me to have Jetty pick up my changes from a
JavaScript file not in the war project?*

Currently, I have clean install both projects and then restart jetty to see
changes.

I am assuming this is common among Wicket users with the advent of component
bound resources.
