Programmatic output of a property's constraints

[burriad]

Hi,

I am looking for a way to programmatically retrieve the values of a list constraint. The example below tries to do exactly this, but does not work as expected.

public List<SelectItem> getStatusValues() {   PropertyDefinition pd = getDictionaryService().getProperty(MyModel.STATUS_PROP);   List<SelectItem> result = new ArrayList<SelectItem>();         for (ConstraintDefinition cd : pd.getConstraints()) {      cd.getConstraint().      result.add(new SelectItem(cd.getName().getLocalName()));   }   return result;}‍‍‍‍‍‍‍‍‍‍‍‍‍

So the expected output in a listbox would be two entries with values "open" and "closed", given the constraint definition below.

<constraint name="enum-status" type="LIST">  <parameter name="allowedValues">     <list>   <value>open</value>   <value>closed</value>    </list>  </parameter></constraint>…<property name="status">  …  <constraints>    <constraint ref="enum-status"/>  </constraints></property>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Unfortunately, all I get is a single entry "status_anon_13". What would be the correct code to produce the desired listbox entries?

Life's not that hard sometimes. A little cast saves the day:

public List<SelectItem> getStatusValues() {   PropertyDefinition pd = getDictionaryService().getProperty(MyModel.STATUS_PROP);   List<SelectItem> result = new ArrayList<SelectItem>();         for (ConstraintDefinition cd : pd.getConstraints()) {      if (cd.getConstraint() instanceof ListOfValuesConstraint) {            ListOfValuesConstraint lc = (ListOfValuesConstraint) cd.getConstraint()            for (String val : lc.getAllowedValues()) {                result.add(new SelectItem(val));            }       }   }   return result;}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
