I tried to do a render for outputText component, but i just can get it right. Below is the code that i wrote.

Bean class:


jsp page


The text is always been shown even if i have set "outputText3.setRendered(false);"
Did i do set the rendering correctly? Where have i gone wrong.

Thanks.

You didn't bind the outputtext to the backing bean. You can use the component's 'binding' attribute for this.

And you should be using the same instance and not creating a new instance inside the checkUpgrade() method.

javax.faces.FacesException: Can't instantiate class: 'view.backing.SCBean'.. class view.backing.SCBean : java.lang.NullPointerException

Instantiate the property itself. Do not create a new one.

Just
or lazily

Point is that you should use the property as reference and not to create a new one which is not related to any property at any way.
