Re: Navigation and Adding Panels dynamically.
Martin,
I could not find any help using this extension. May be I missed something
somewhere.
Let's look at a peice of code of what I am trying to do:
private void setScreen(String screen) {
try {
Panel myPanel;
myPanel = (Panel)
Class.forName(com.mycompany.components.+screen).newInstance();
screenPanel.replaceWith(myPanel);
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
So assuming I need to display a screen called EditUserScreen, I need
to load
myPanel = (Panel)
Class.forName(com.mycompany.components.EditUserScreen).newInstance();
With the above code everything works fine. But Nothing is replaced. I
mean it executes with with no error, but the new panel is not shown. One
more thing to mention, if I add additional components in the
EditUserScreen Panel class, without adding them in the html, I see NO
error generated ! Is't correct to conclude that the html template for
EditUserScreen is never parsed, and instead the Panle.java is used ?
Shouldn't the old panel should be removed in this case, at least?

If you know something else that can work for these requirements please
advice me.

You'll need custom logic to check whether the previous/next wizard step
should be shown to the current user depending on its privileges.

Re: Navigation and Adding Panels dynamically.
Foo.class.newInstance() will use zero arg constructor which is not
possible because
panel has no zero arg. constructor so basically you got the exception
at that line itself :)
just pass the panel id in screen method and one enum which helps you
in identifying the panel type you want to create
and then create a panel instance in a normal way etc. what you want to do..

Re: Navigation and Adding Panels dynamically.
Vineet,
thank you for replying.
I don't think this is the issue, because the panels I am creating, have
their Id's set directly in the constructor. For example,
public EditUserScreen(){
super(workScreen);
setOutputMarkupPlaceholderTag(true);
setOutputMarkupId(true);
}
And basically they all have the same Id.
However, I don't think this has anything to do with creation of the
Panels anymore. I have just tried something like:
EditUserScreen screen = new EditUserScreen();
currentPanel.replaceWith(screen);
currentPanel = screen;
Still nothing changed. So it doesn't look to me like the wat I am
creating the panel is the problem. I think there is issues with the way
I am using replaceWith method.
Any ideas ?

Re: Navigation and Adding Panels dynamically.
sorry i wrongly assumed you might not have defined zero arg constructor..
you dont need setOutputMarkupId(true) as you are already using
setOutputMarkupPlaceholderTag(true)
and yes you are using replacewith correctly ,i dont think there is any
problem in this code..

Re: Navigation and Adding Panels dynamically.
Hello Vineet,
I resolved the issue. I didn't add the panel to the Ajax request target.
So
ajaxRequestTarget.add(currentPanel);
solved the issue.
Thank you.
