Andrei Markavtsov updated RF-6267:
----------------------------------

    Description: 
Rendered attribute should be passed to appropriate created column . It should not be used for whole columns component rendering on the page.

Code sample:

public class Bean implements Serializable{
	
	List<String> rows = Arrays.asList(new String [] {"", "", ""});
	List<Column> columns = Arrays.asList(new Column [] {new Column("Column1", false), new Column("Column1", true)});
	

	public List<String> getRows() {
		return rows;
	}

	public void setRows(List<String> rows) {
		this.rows = rows;
	}

	public List<Column> getColumns() {
		return columns;
	}

	public void setColumns(List<Column> columns) {
		this.columns = columns;
	}
	
		
}

public class Column {
	
	String name;
		
	boolean rendered;
	
	public Column(String name, boolean rendered) {
		super();
		this.name = name;
		this.rendered = rendered;
	}

	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}

	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}


	public boolean isRendered() {
		return rendered;
	}

	public void setRendered(boolean rendered) {
		this.rendered = rendered;
	}
}


<rich:dataTable value="#{bean.rows}">
	<rich:columns value="#{bean.columns}" var="col" rendered="#{col.rendered}">
		<h:outputText value="Text" />
	</rich:columns>
</rich:dataTable>
