Null pointer exception

[Former Member]

Hi,

I have created a separate dc for my model exposed the model as public part and using the model dc as a child dc in the main dc.

Now when I create instances of the model classes it is throwing a null pointer error what may be the problem.

java.lang.NullPointerException

Hi,

First of all.. have you deployed the DC where you have created the model and exposed the model.

If deployed, have you created two public parts API and SDA for the model.

Add this two public parts to the DC where you are using this model.

Build the DC and deploy.

Hope this helps you in resolving your problem

Regards,

Saleem
