Defining mask globally

[Sanjay Choudhary]

hi

I wish to define the global regex for masks in a common file. For example ,
name field mask will be like ^[a-zA-Z]+$.

<h:inputText id="nameame" styleClass="inputText"
                   value="#{BrokerRepresentative.name}" size="20">
                   <val:commonsValidator type="mask" arg="Company Name"
server="true"
                       client="false">
                       <val:validatorVar name="mask" value="^[a-zA-Z]+$" />
                   </val:commonsValidator>
               </h:inputText>

I wish to replace this with something like

<f:loadBundle basename="globalmasks" val="globalmask"/>

<h:inputText id="nameame" styleClass="inputText"
                   value="#{BrokerRepresentative.name}" size="20">
                   <val:commonsValidator type="mask" arg="Company Name"
server="true"
                       client="false">
                       <val:validatorVar name="mask" value="#{
globalmask.name}" />
                   </val:commonsValidator>
               </h:inputText>

This will enable me to validate the name field in a uniform way through out
my application. Also if any change is need in regex then it needs to applied
in one place.  When I tried this solution  I got


java.lang.NullPointerException

Any help /commens/ pointers appreciated to resolve this problem.  I open to
different solution too.
