falcon — Thu, 09 Jul 2009 07:41:51 GMT

Hi,I have defined a custom type metadata, like this:<constraints> <constraint name="my:constraintList" type="LIST"> <parameter name="allowedValues"> <list> <value>OPTION 1</value> <value>OPTION 2</value>

call it with :
getListOfValuesConstraint(dictionaryService, QName.createQName(
"yourURI",
"propertyTest");

this bean will be injected by Spring IoC layer… see faces-config-beans.xml, or any file in tomcat/shared/classes/alfresco/extension that ends up with "-context.xml" to see how services are built

Is there any way of using the translation functionality for a List constrains ?
i.e is there a <label> tag you can use or something ?

<value label="id-aaa">aaaa</value>

I also want to obtain the list of constraint values, however, the obove mentioned line:

propertyDef.getConstraints();‍

I don't have a getContraints member in PropertyDefinition class. I use the remote WebService API from Alfresco 3.2.
What am I doing wrong?

we have below repository webscript available by using it we can list down all the constraint associated with particular property. You will have to provide appropriate class name and property name to get details.

/alfresco/s/api/classes/{classname}/property/{propname}

For example in bpmModel.xml we have LIST constraint for bpm:status property and get can get those constraint details as below (values in allowedValues array) :

http://127.0.0.1:8080/alfresco/s/api/classes/imwf_moderatedInvitationSubmitTask/property/bpm_status



   {
      "name" : "bpm:status",
      "title" : "Status",
      "description" : "Status",
      "defaultValues" : "",
      "dataType" : "d:text",
      "multiValued" : false,
      "mandatory" : true,
      "enforced" : false,
      "protected" : false,
      "indexed" : true,
      "indexedAtomically" : true,
      "constraints" :
      [
      { 
         "type" : "LIST",
         "parameters" : 
         [
            {
               "allowedValues" : ["Not Yet Started","In Progress","On Hold","Cancelled","Completed"]
            }
               ,
            {
               "sorted" : false
            }
               ,
            {
               "caseSensitive" : true
            }
               
         ]
      }
      ],
      "url" : "\/api\/property\/bpm_status"
   }

You can get complete class definition for all deployed types using below web script :
