How to handle Variant Value Category sibling validation exception in Integration Object.

[former_member678491]

While creating Integration object for VariantCategory and VariantValueCategory I am getting NullPointerException.

Logic written in Interceptor :

VariantValueCategoryModel currentCategory;

List siblings = variantCategory.getCategories();

if (!siblings.contains(currentCategory)) { sequences.add(currentCategory.getSequence()); }

Now if you see the above code, siblings must be null when you will try to create the first VariantValueCategory inside a VariantCategory. In that case null.contains() will throw exception.

How will I handle this or more correctly what I am supposed to do ?

Please help.

Is this your custom code or this is code from the integrationserviers/odata2services extensions? If so, could you point out to its location.

I'm assuming you're talking about a custom code. I don't fully understand your business case, but in terms of a technical solution here is what you can do:

 List siblings = variantCategory.getCategories != null
     ? variantCategory.getCategories
     : Collections.emptyList()

Another option would be:

 if (siblings == null || !siblings.contains(currentCategory)) { ... }
