GSP Accessing domain class static field

Question

I have a domain class which contains a Class[] array. I want the contents of that array displayed using g:select. Although I cannot find how to access those fields. I tried <%@page import="package.path.to.PropertyDefinition" %> and then

<g:select from="${PropertyDefinition.types}" name="cust_prop_type"/>

Although I am getting a very big exception of type org.codehaus.groovy.control.MultipleCompilationErrorsException

Is it possible to access that static Array without making use of a Controller class?

I am using version 2.3.7

class PropertyDefinition {

     @Transient
    public static final Class[] validTypes = [Integer.getClass(), String.getClass(), RefdataValue.getClass(), BigDecimal.getClass()]
.
.
.

Exception:

Caused by: java.lang.NullPointerException at org.springsource.loaded.ri.ReflectiveInterceptor.jlrMethodGetParameterAnnotations(ReflectiveInterceptor.java:944) at org.codehaus.groovy.vmplugin.v5.Java5.configureClassNode(Java5.java:357) at org.codehaus.groovy.ast.ClassNode.lazyClassInit(ClassNode.java:258) at org.codehaus.groovy.ast.ClassNode.getInterfaces(ClassNode.java:353) at org.codehaus.groovy.ast.ClassNode.declaresInterface(ClassNode.java:945) at org.codehaus.groovy.ast.ClassNode.implementsInterface(ClassNode.java:925) at org.codehaus.groovy.ast.ClassNode.isDerivedFromGroovyObject(ClassNode.java:915) at org.codehaus.groovy.classgen.AsmClassGenerator.isGroovyObject(AsmClassGenerator.java:937) at

the exception you are getting can be also narrowed down to the `cause`, as `MultipleCompilationErrorsException` is saying only, that you messed-up but gives no hint on `where` — injecteer, Jun 25 '14 at 08:48
Your definition can be `@Transient static final Class[] validTypes = [Integer, String, RefdataValue, BigDecimal]` but that's probably not the issue . — tim_yates, Jun 25 '14 at 09:09
@injecteer depends if you want the list serialised the the database with the domain class... — tim_yates, Jun 25 '14 at 09:41

You've declared

public static final Class[] validTypes

in PropertyDefinition but you're accessing PropertyDefinition.types in the GSP...

Jaw dropped while reading this. The stupidity of the mistake is too damn high. http://s3.amazonaws.com/rapgenius/tumblr_lq98myTmBo1qcnum8.jpg – Giannis Jun 25 '14 at 09:46
