Re: Adding components in datatable dynamically.

[ved.gunjan]

Hi Mike,

I agree that we can do the way u have suggested...but what is wrong in my code and why im not able to get any components created in the datatable...

Here's the code:

JSP

---------------------------------

<h:dataTable id="mainTable" binding="#{dynamicQuestions.dataTable}" value="#{requirementBean.questionList}"

var="questions" border="1"/>

 

Java method

-------------------------------

  public UIData getDataTable()

{

Application application = FacesContext.getCurrentInstance().getApplication();
        UIViewRoot uiViewRoot =  FacesContext.getCurrentInstance().getViewRoot();
         HtmlDataTable dataTable =(HtmlDataTable)uiViewRoot.findComponent("mainTable");

//------------------- adding HtmlOutputText ---------------//
        String vbStr = "#{questions.questionData}";
        ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding(vbStr);
        HtmlOutputText output = new HtmlOutputText();
        output.setId("HtmlOutputText1");
        output.setValueBinding("value", vb);
   

//------------------- adding HtmlSelectOneMenu ---------------//
        vbStr = "#{questions.itemList}";
        vb = FacesContext.getCurrentInstance().getApplication().createValueBinding(vbStr);
   
        HtmlSelectOneMenu hsom = new HtmlSelectOneMenu();
        hsom.setId("HtmlSelectOneMenu2");
        hsom.setValueBinding("value",vb);

 //------------------- adding HtmlSelectManyListbox ---------------//

        vbStr = "#{questions.itemList}";
        vb = FacesContext.getCurrentInstance().getApplication().createValueBinding(vbStr);
   
        HtmlSelectManyListbox hsmlb = new HtmlSelectManyListbox();
        hsmlb.setId("HtmlSelectManyListbox3");
        hsmlb.setValueBinding("value",vb);

    //datatable column
        UIColumn column = new UIColumn();
        column.setId("UIColumn4");
        column.getChildren().add(output);
        column.getChildren().add(hsom);
        column.getChildren().add(hsmlb);
   
       dataTable.getChildren().add(column);

 return dataTable;

}

There's a much easier way to do this.
