CDK dies with a NullPointerException

Hi everyone,

I am trying to use the CDK to generate a new component and currently it dies with a NullPointerException with reading the document configuration file.

How can I get more information about what the error might be?

Thanks in advance,

please add more details on component configuration you defined.

Hi Ilya,

I managed to get through it.

The error went away after I removed some property entries, which weren't available on the component class.

Maybe better error checking code be done on the CDK?

I have now another issue, but I will post it on a separate thread.

Hi,

CDK in 4.x will have much better errors handling.
