Configure child resources as mandatory or its cardinality in ResourceDefinition ------------------------------------------------------------------------------- Key: WFCORE-314 URL: https://issues.jboss.org/browse/WFCORE-314 Project: WildFly Core Issue Type: Enhancement Components: Domain Management Reporter: Pedro Igor Currently, the ResourceDefinition does not provide a good way to configure a child resource as mandatory or even its cardinality. Instead of that, manual validations are required inside handlers. The idea is remove manual validations and let it be done automatically by the model. Considering the following example: {code:xml} <parent-resource> <child-resource/> </parent-resource> {code} Would be useful if we could mark the 'child-resource' above as mandatory. Or even: {code:xml} <parent-resource> <child-resource/> <child-resource/> <child-resource/> <child-resource/> <!-- This is invalid. Only 3 childs are supported. --> </parent-resource> {code} Where we can specify the cardinality for a child-resource so we can configure the min/max occurrences. I think the latter approach is more flexible and can be used to get a resource as mandatory or specify its number of occurrence.
