Wicket's error message-> java.lang.IllegalStateException: This
container is already dequeing
I am trying out the Wicket framework using version 8. I have been battling
this strange error without success. I am using Payara application server on
Windows 10 The required info is below, any tips or help in finding out where
the problem is would be appreciated. I looked into stackoverflow, pretty
much any help sites for similar questions but did not find any.
It seems deque preamble is being called erroneously by wicket.
Java Source below
public class PrescientHome extends PrescientTemplateOriginalPage {
private Model<ZipManagedBean> zipManager;
private Form occForm;
private WebMarkupContainer tagFrame;
private Login login;
private Model<String> occupationListModel;
private List <String> occupationList;
private DropDownChoice<String> occupationChoices;
public PrescientHome()
{ super(); }
@Override
protected void onInitialize() {
super.onInitialize();
zipManager=Model.of(new ZipManagedBean());
login=new Login();
login.setResponsePage(Login.class);
occupationListModel= new Model<>();
occupationList=zipManager.getObject().getOccCode();
occupationChoices=new
DropDownChoice<>("occupationModel",occupationListModel, occupationList );
occForm=new Form("occupationForm"){
@Override
protected void onSubmit()
{ super.onSubmit(); }
};
occForm.add(occupationChoices);
add(occForm);
tagFrame=new WebMarkupContainer("TagFrame");
tagFrame.add(login);
add(tagFrame);
}
}

Re: Wicket's error message-> java.lang.IllegalStateException: This

Posted by LSomefun <oy...@gmail.com>.
PrescientTemplateOriginalPage is actually the parent class of PrescientHome
so that why PrescientTemplateOriginalPage had the <wicket:child/> tag, and
prescientHome had the <wicket:extend>.
I was able to solve the problem and your assistance was greatly appreciated.
The problem is seems was how I was referring my form id. I needed to put
<form wicket:id="occupationForm"> and not <form id="occupationForm"> .
Francois thank you so much for all your assistance.

I don't think I have the privileges to do but let Martin Tzvetanov Grigorov
know to close the issue on Jira.

you are adding the header and the footer panels in the child page but the html tag is in the super class.

Posted by LSomefun <oy...@gmail.com>.
I do appreciate you looking at this while on holiday. The 2nd constructor of
PrescientTemplateOriginalPage I have deleted. Truth is it was not needed.
The HTML code of PrescientHome I initially submitted did not include the
HeaderPanel and footerPanel, was because of inheritance from
PrescientTemplateOriginalPage so did not need to include them.
The HTML Code from PrescientTemplateOriginalPage is below
<html>
<head>
<title>Template</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,
initial-scale=1.0">
</head>
<body>
<div id="header" wicket:id="headerPanel"/>
<wicket:child/>
<div id="footer" wicket:id="footerPanel"/>
</body>
</html>
And the HTML code from PrecientHome is below
<html>
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,
initial-scale=1.0">

There are few problems I can see (from my mobile, being on hollidays )
First you should not pass component to PrescientTemplateOriginalPage constructor's argument.
Second : in the second constructor you do not add the panels to the page
Third : in the html code the header and footer tags are not presents

Could you show us the new stacktrace and the PrescientTemplateOriginalPage code ?

Thanks for your reply Francois, much appreciated. Even when I adjust my code
and remove the login object from the source code and from the html tag like
the code below I still get the same error I was encountering. I definitely
will try version 9 in the near future as soon as I can solve the current
problem the framework is showing.

Re: Wicket's error message-> java.lang.IllegalStateException: This

Posted by Francois Meillet <fr...@gmail.com>.
If what you want is redirecting the user to the Login page after the form submit,
you need to remove all references to the Login class in the PrescientHome class,
then in the form # onSubmit you can use the code setResponsePage(Login.class).
Have a look at wicket links and wicket forms
https://ci.apache.org/projects/wicket/guide/8.x/single.html#_wicket_links
https://ci.apache.org/projects/wicket/guide/8.x/single.html#_wicket_forms
By the way you should give a try to Wicket 9 !
Hope this help
