JUEl and Spring activiti engine configuration

[hell_keeper]

Hello, is it possible to configure the JUEL engine inside the activiti engine with a full spring configuration ?

For my workflow I need to have a JUEL engine which acceptes null values. JUEL documentation  precises that the propertie : "javax.el.nullProperties" should be set to our need.

But how can we set this propertie with a org.activiti.spring.SpringProcessEngineConfiguration or org.activiti.spring.ProcessEngineFactoryBean ?

Thanks for your replies.

Hi,
if you put a breakpoint in this method can you see the properties loaded from your el.properties file?
<code>
public ExpressionFactoryImpl(Profile profile) {
  Properties properties = loadProperties("el.properties");
  this.store = createTreeStore(1000, profile, properties);
  this.converter = createTypeConverter(properties);
}
</code>
