| [emf-dev] Cannot set content of particle |
|
Hi, I am using the eclipse XSD API to rewrite schemas. I am
trying to add particles to a model group. The added particles should be based
on an existing particle in the model group, but with a different element
content. Hence, I clone a particle, using particle.cloneConcreteComponent(true,
true). I set an existing element as the content of this particle. However, when
I do this, I get the following exception: java.lang.NullPointerException at

(XSDParticle)particle.cloneConcreteComponent(true, true); particleClone.setContent(modelGrpSubstitutableElement); //This is
where the error occurs Am I using the cloneConcreteComponent method correctly. Is
there something else I need to call after particle.setContent? Any help is greatly appreciated! Thanks, Michael |
