Oh ... you mean to say that once we have a html page with certain components
then it is not possible to add new components to that existing page at
runtime.

That's an entirely wrong way of doing things. You should view your
templates like you would view Java files. Once you deploy your
application, you don't change those. Instead learn how to use panels
and maybe component replacement.

Hi,
I am new to wicket.
I am working on a small scenario, where in I am trying to change the
contents of an html page and navigating to that page while the
application
is running.
The code is as follows .
My first page is Demo.html, in which I am adding a simple link element.
html
body
div Message goes here /div
Just testbr
Test page
/body
/html
In Demo.java, inside the onclick() event of the 'link' I am trying to add
content to a html file called ShowEnty.html with a component and
initializing the corresponding ShowEnty.java.
public class Demo extends WebPage
{
File outputFile = new File(C:\\web\\pages\\ShowEntry.html);
public Demo()
{
IModel messageModel = new Model(Hello World!);
final String compName = msgInputForm;
Link link = new Link(link) {
public void onClick() {
ShowEntry showEntry = new ShowEntry(compName);
try{
FileWriter out = new FileWriter(outputFile);
out.append(htmlform wicket:id=+compName+input
type=\text\
wicket:id=\messageInput\/input type=\submit\
value=\update\//form/html);
out.close();
}catch(IOException iox){iox.printStackTrace();}
setResponsePage(showEntry);
}
};
add(link);
Label message = new Label(message, messageModel);
link.add(message);
}
Now the ShowEntry.html looks like the following code with a form, having
a
input text field and a submit button (as the contents I was adding from
the
onclick() method in the above Demo.java)...
html
form wicket:id=msgInputForm
input type=text wicket:id=messageInput/
input type=submit value=update/
/form
/html
Similarly the ShowEntry.java is as follows
public class ShowEntry extends WebPage{
public ShowEntry(String component) {
IModel messageModel = new Model(Hello World!);
add(new MessageForm(component, messageModel));
}
private final class MessageForm extends Form
{
public MessageForm(String id, IModel model)
{
super(id);
add(new TextField(messageInput, model));
}
protected void onSubmit()
{
System.out.println(inside submit);
}
}
}
My problem now is, as I was writing the html text into the file, I need
to
wait to see the contents or probably restart my tomacat.
Is there any way that we can write this html content to the in-memory
file
to have the immediate effect instead of writing it to a file on the disk.
