NullPointerException when calling getLexicalFacetValue() on XSSimpleTypeDefinition

[Martin Lambert <Ma...@denovopharma.com>]

Hi,

Thanks everybody for your help with my previous questions. 

I am currently attempting to retrieve information from attribute types, in particular their facets. I am aware of the type heirachy i.e. anySimpleType --> decimal --> integer and have been able to retrieve the individual type objects. I make the assumption that facets are solely attached to the type in which they are defined. E.g. given the type definition below, maxInclusive=0 would be attached to the 'negIntegerType' object and not any of the ancestor type objects.


      <simpleType name="negIntegerType">
	      <restriction base="integer">
		 <maxInclusive value="0"/>
	      </restriction>
      </simpleType>

<attribute name="elMin" type="negIntegerType" use="required"/>


My problem comes when tyring to call getLexicalFacetValue() using facets that are not associated with the given type. To illustrate I will use the example above, I would expect calling getLexicalFacetValue(FACET_MAXINCLUSIVE) on a 'decimal' type object to return null as stated in the Javadoc but instead it throws a null pointer exception.

Below is the code I'm using and the stack trace that I get:


            System.out.println("::::::::::::: TYPE NAME: " + typeDef.getName());
            
            // Make sure that the value can be turned into a decimal.
            Double.parseDouble(attributeValue.toString());
                         
            System.out.println("^^^^ TODO: Add validation logic");                        

            String maxInclusive = typeDef.getLexicalFacetValue(XSSimpleTypeDefinition.FACET_MAXINCLUSIVE);
            
            if(maxInclusive != null)
            {
                System.out.println("Max. inclusive facet found!!!");
            }
            else
            {
                System.out.println("Max. inclusive facet NOT found!!!");
            }
