[jboss-dev-forums] [Design the new POJO MicroContainer] - Re: setting managed property of type List

Hmmm, looking at the MetaValueFactory.create(Object value) for value == List(Integer), this seems to be broken or at least the relevant information about element values gets lost. This is what this method returns for non-empty Integer ArrayList. | metaValue: org.jboss.metatype.api.values.MetaValue = {org.jboss.metatype.api.values.ArrayValueSupport(a)824}"ArrayMetaType{type=[Lorg.jboss.metatype.api.values.CompositeValue; dims=1 elementType=MutableCompositeMetaType{java.lang.Object}:[CompositeValueSupport: metaType=[MutableCompositeMetaType{java.lang.Object}] items=[], CompositeValueSupport: metaType=[MutableCompositeMetaType{java.lang.Object}] items=[]]" | metaType: org.jboss.metatype.api.types.ArrayMetaType = {org.jboss.metatype.api.types.ArrayMetaType(a)829}"ArrayMetaType{type=[Lorg.jboss.metatype.api.values.CompositeValue; dims=1 elementType=MutableCompositeMetaType{java.lang.Object}" | dimension: int = 1 | elementType: org.jboss.metatype.api.types.MetaType = {org.jboss.metatype.plugins.types.MutableCompositeMetaType(a)840}"MutableCompositeMetaType{java.lang.Object}" | primitiveArray: boolean = false | cachedHashCode: int = -2147483648 | cachedToString: java.lang.String = {java.lang.String(a)833}"ArrayMetaType{type=[Lorg.jboss.metatype.api.values.CompositeValue; dims=1 elementType=MutableCompositeMetaType{java.lang.Object}" | className: java.lang.String = {java.lang.String(a)850}"[Lorg.jboss.metatype.api.values.CompositeValue;" | description: java.lang.String = {java.lang.String@851}"1-dimension array of java.lang.Object" | typeName: java.lang.String = {java.lang.String(a)852}"[Lorg.jboss.metatype.api.values.CompositeValue;" | array: boolean = true | value: java.lang.Object = {java.lang.Object[2]@830} | [0] = {org.jboss.metatype.api.values.CompositeValueSupport@834}"CompositeValueSupport: metaType=[MutableCompositeMetaType{java.lang.Object}] items=[]" | contents: java.util.SortedMap = {java.util.TreeMap@839} size = 0 | metaType: org.jboss.metatype.api.types.CompositeMetaType = {org.jboss.metatype.plugins.types.MutableCompositeMetaType(a)840}"MutableCompositeMetaType{java.lang.Object}" | cachedHashCode: int = -2147483648 | [1] = {org.jboss.metatype.api.values.CompositeValueSupport@834}"CompositeValueSupport: metaType=[MutableCompositeMetaType{java.lang.Object}] items=[]" | contents: java.util.SortedMap = {java.util.TreeMap@839} size = 0 | metaType: org.jboss.metatype.api.types.CompositeMetaType = {org.jboss.metatype.plugins.types.MutableCompositeMetaType(a)840}"MutableCompositeMetaType{java.lang.Object}" | cachedHashCode: int = -2147483648 The problem is that Object is recognized as lists/arrays element type instead of Integer (runtime object doesn't carry generics info). Hence elements are Composite types instead of primitive number type. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111219#...
