Hi All,

I am trying datatable with dynamic columns using rich:coulumns in seam.

Following is my test.xhtml file :

<ui:define name="main">
<f:facet name="header">Test Data Table</f:facet>
<rich:panel><f:facet name="header">Data Table </f:facet>
<h:form>
<rich:dataTable value="#{rowList}" var="tableObj" width="750">
<f:facet name="header">
<h:outputText value="Rules"></h:outputText>
</f:facet>
<rich:columns value="#{columnList}" var="colm">
<f:facet name="header">
<h:outputText value="#{colm.header}"/>
</f:facet>
<h:outputText value="#{tableObj[0]}"/>
</rich:columns>
</rich:dataTable>
</h:form>
</rich:panel>
</ui:define>
Following is my backing bean :

@Stateless
@Name("testManager")
@Scope(ScopeType.SESSION)
public class TestManagerBean implements TestManager {
@Logger private Log log;
@In FacesMessages facesMessages;
@DataModel(scope = ScopeType.PAGE)
List<Object[]> rowList;
@DataModel(scope = ScopeType.PAGE)
List columnList;

@Factory("columnList")
public void populateColumnList(){
columnList=new ArrayList();
columnList.add(new Column("First-Name"));
columnList.add(new Column("Middle-Name"));
columnList.add(new Column("Last-Name"));
}
@Factory("rowList")
public void populateRowList()
{
rowList = new ArrayList<Object[]>();
Object[] names1=new Object[] {"Test1,Test2,Test3"};
Object[] names2=new Object[] {"Test4,Test5,Test6"};
rowList.add(names1);
rowList.add(names2);
}
@Remove
public void remove() {
// TODO Auto-generated method stub
}

My Column.java

public class Column {
private String header;

public Column(String header){
this.header=header;
}
public String getHeader(){
return header;
}

public void setHeader(String header){
this.header=header;
}

}

My datatable is not displayed (or you can say its displying empty datatable).

I suspect following reason because if i use rich:column it works fine (but it becomes static which i dont want):

The <rich:columns> tag is initialized during components tree building process.
This process precedes page rendering at "Render Response" JSF phase.

Please tell me what 's wrong here.

Thanks a lot in advance.

Its urgent because i have already spent couple of days and didnt get any outcome.

Manish
