Hi Sven,

I came across this stackeroverflow link and tried it but couldn't get the
markupcontainer to load the markup. I'll give it another go...

Hi,

Managed to get this working by using a Panel instead of a
WebMarkupContainer. Here's the code.


import org.apache.wicket.MarkupContainer;
import org.apache.wicket.markup.IMarkupResourceStreamProvider;
import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.util.resource.AbstractResourceStream;
import org.apache.wicket.util.resource.IResourceStream;
import org.apache.wicket.util.resource.ResourceStreamNotFoundException;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;

public class WicketHtmlContainer extends Panel implements
IMarkupResourceStreamProvider {
  public WicketHtmlContainer(String id) {
super(id);
Form form = new Form(form);
form.add(new TextField(myinput));
add(form);
  }

  public IResourceStream getMarkupResourceStream(MarkupContainer container,
Class? containerClass) {
System.out.println(calling getMarkupResourceStream());

return new AbstractResourceStream() {

  public InputStream getInputStream() throws
ResourceStreamNotFoundException {
return new ByteArrayInputStream(getHtml().getBytes());
  }

  public void close() throws IOException {
  }
};
  }
  
  private static String getHtml() {
String html =
wicket:panelform wicket:id=\form\ +
my text +
input wicket:id=\myinput\ type=\text\ / +
input type=\submit\ value=\submit\/ +
/form/wicket:panel;
return html;
  }
}

Hi,

I don't know if you might find this helpful, but if your component must 
generate a different markup from request to request, you should 
implements interface IMarkupCacheKeyProvider to avoid markup caching:


 /**
 * Must return null to avoid markup caching
 */
@Override
public String getCacheKey(MarkupContainer arg0, Class? arg1) {
return null;
}

Andrea, yes, I'm sure I would have come across this problem, so thanks for
the tip.

Hi everyone,

I want to load some markup stored in a string, this markup also has
references to wicket components that I need to create and then add to
whatever will contain the markup. Is this possible and how can I do this?

   private static String getHtml() {
 String html =
 form wicket:id=\form\ +
 my text +
 input wicket:id=\myinput\ type=\input\ / +
 input type=\submit\ value=\submit\/ +
 /form;
 return html;
   }

Cheers,
Alinoor
