Hi bigchill,
a possible solution could be:
1. create a bean containing following methods & attributes
public class MyBean
     // initial value
     private boolean disabled= true;
     public String doSomething()
          this.disabled= false;
          return null;
     public void setDisabled(boolean pDisabled)
          this.disabled= pDisabled;
     public boolean isDisabled()
          return disabled;
}2. Create an instance of the bean on a certain scope (depending on your requirements)
3. Link the disabled attribute of the input component with the disabled property of the bean and link the "doSomething" bean method with the action attribute of the commandButton:
<af:inputText label="Some textfield" disabled="#{s_myBean.disabled}"/>
<af:commandButton action="#{s_myBean.doSomething}"/>That's it.
Kind regards,
