Building the component dynamically

 Top  Previous  Next

To build the component dynamically using different data sources, the below approach should be used :

 

1.Create the selection and/or data models. For example:

 

public class TreeSelectionModelBean extends TreeSelectionModel {

 

       public TreeSelectionModelBean () {

               super ();

               this.setCurrentSelection ( "1" );

       }

}

 

 

2.Declare the bean to use(this method of models instantiation is used for compatibility purposes only. We recommend using of JSF managed beans for the component models - see the item below ) on JSP page :

 

<jsp:useBean id="treeSampleSelectionModel"

               class="testingapplication.tree.TreeSelectionModelBean"

               scope="session">

</jsp:useBean>

 

 

3.Define dataModel and/or selectionModel tag to specify which model to use.

 

<tree:treeSelection model="treeSampleSelectionModel"/>
