Binding HtmlCommandLink to backing bean method programmatica

[rvaneperen]

I am creating a commandLink programmatically. I have everything working except to bind the link to a method in the backing bean. I don't see anything except a deprecated setAction() method on the class. How do I do this? Here's what I have so far:

validateLink = new HtmlCommandLink();
 validateLink.setId("validateLink" + dataset.getId());
 validateLink.setRendered(true);
 validateLink.setImmediate(true);
 validateLink.setTitle("Begin the Validation Process for this Dataset");
 validateLink.setValue("Validate Dataset");

Thanks,
Ray

Hi there,

maybe you solved it already, but here it goes.

Try the addActionListener.. I think it works the same way AWT-Listeners.

import javax.faces.event.ActionEvent;
import javax.faces.event.ActionListener;


...
validateLink.addActionListener(new ActionListener() {
public void processAction(ActionEvent evt) {
// do something
}
});

Thanks for the reply. I ended up creating the following utility method, which works fine:

 public static HtmlCommandLink buildCommandLink(final String pId, final String pExpression, final String pTitle,
 final String pValue, final boolean pImmediate, final boolean pRendered)
 {
 ExpressionFactory factory = ExpressionFactory.newInstance();
 MethodExpression expression = factory.createMethodExpression(FacesContext.getCurrentInstance().getELContext(),
 "#{" + pExpression + "}", String.class, new Class[0]);

 HtmlCommandLink link = new HtmlCommandLink();
 link.setId(pId);
 link.setRendered(pRendered);
 link.setImmediate(pImmediate);
 link.setTitle(pTitle);
 link.setValue(pValue);
 link.setActionExpression(expression);

 return link;
 }
