Subject [jira] Commented: (MYFACES-587) Behandlung von <map-entries>- und <list-entries>-Elementen entspricht nicht den Vorgaben von JSR-127

    [ http://issues.apache.org/jira/browse/MYFACES-587?page=comments#action_12367949 ] 

Manuel Ohlendorf commented on MYFACES-587:
------------------------------------------

It is still not possible to use a java.util.TreeMap as a managed property!

> Zur Initialisierung einer Map- bzw. List-Property wird scheinbar immer eine HashMap bzw.
ArrayList verwendet.
> Die in JSR-127 gemachten Vorgaben werden nicht umgesetzt.
> Kopiert aus JSR-127 Version 1.1:
> "The initialization bean properties from <map-entries> and <list-entries>
> elements must adhere to the following algorithm, though any confirming
> implementation may be used.
> For <map-entries>:
> 1. Call the property getter, if it exists.
> 2. If the getter returns null or doesn't exist, create a java.util.HashMap,
> otherwise use the returned java.util.Map.
> 3. Add all entries defined by nested <map-entry> elements in the order they are
> listed, converting key values defined by nested <key> elements to the type
> defined by <key-class> and entry values defined by nested <value> elements
> to the type defined by <value-class>. If a value is given as a value binding
> expression, evaluate the reference and store the result, converting to <valueclass>
> if necessary. If <key-class> and/or <value-class> are not defined,
> use java.lang.String. Add null for each <null-value> element.
> Chapter 5 Value Binding and Method Binding Expression Evaluation 5-13
> 4. If a new java.util.Map was created in step 2), set the property by calling the
> setter method, or log an error if there is no setter method.
> For <list-entries>:
> 1. Call the property getter, if it exists.
> 2. If the getter returns null or doesn't exist, create a java.util.ArrayList,
> otherwise use the returned Object (an array or a java.util.List).
> 3. If a List was returned or created in step 2), add all elements defined by nested
> <value> elements in the order they are listed, converting values defined by
> nested <value> elements to the type defined by <value-class>. If a value
is
> given as a value binding expression, evaluate the reference and store the result,
> converting to <value-class> if necessary. If a <value-class> is not defined,
> use the value as-is (i.e., as a java.lang.String). Add null for each <nullvalue>
> element.
> 4. If an array was returned in step 2), create a java.util.ArrayList and copy all
> elements from the returned array to the new List, wrapping elements of a
> primitive type. Add all elements defined by nested <value> elements as
> described in step 3).
> 5. If a new java.util.List was created in step 2) and the property is of type
> List, set the property by calling the setter method, or log an error if there is no
> setter method.
> 6. If a new java.util.List was created in step 2) and the property is a java array,
> convert the List into an array of the property type, and set it by calling the setter
> method, or log an error if there is no setter method.
> 7. If a new java.util.List was created in step 4), convert the List to an array
> of the proper type for the property and set the property by calling the setter
> method, or log an error if there is no setter method."
