Grails bean-fields plugin
- by Don
Hi,
I'm having problems using the Grails bean-fields plugin with a class this is annotated Validateable, but is not a domain/command class. The root cause of the problem appears to be in this method of BeanTagLib.groovy
private def getBeanConstraints(bean) {
if (bean?.metaClass?.hasProperty(bean, 'constraints')) {
def cons = bean.constraints
if (cons != null) {
if (log.debugEnabled) {
log.debug "Bean is of type ${bean.class} - the constraints property was a [${cons.class}]"
}
// Safety check for the case where bean is no a proper domain/command object
// This avoids confusing errors where constraints comes back as a Closure
if (!(cons instanceof Map)) {
if (log.warnEnabled) {
log.warn "Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}]"
}
}
} else {
if (log.warnEnabled) {
log.warn "Bean of type ${bean.class} has no constraints"
}
}
return cons
} else return null
}
I tested out this method above in the grails console and when I pass an instance of MyBean into this method, it logs:
Bean of type ${bean.class} is not a
domain class, command object or other
validateable object - the constraints
property was a [${cons.class}]
Because the constraints are returned as an instance of Closure instead of a Map. If I could figue out how to get a Map reference to the constraints of a @Validateable class (that is not a domain/command class), I guess I could resolve the problem.
Thanks,
Don
