I just added value="#{hostInfoBean.serviceType}" to the tag. And in the java
bean the declaration is like ,
private List<String> serviceType = new ArrayList<String>();
Is this correct?
But still I am getting the same error,
hostInfo:serviceTypes: Validation Error: Value is not valid
hostInfo:serviceTypes: Validation Error: Value is not valid

Suresh
