suppress the error message "We detected rows with varying number offields, this is not allowed in a transformation."

I am writing a new step that allows input from 2 previous steps. It is
fine that the row layout of the previous steps is not equal, so i
would like to suppress the error message "We detected rows with
varying number of fields, this is not allowed in a transformation."
Does someone know how to do this?

Hi Gunter,

There is a method in StepMetaInterface that handles this:

/**
* This method is added to exclude certain steps from layout checking.
* @since 2.5.0
*/
public boolean excludeFromRowLayoutVerification();

Just have it return false in your *Meta class.

Good luck!

Matt

Hi Matt,

Thanks for the quick reply.

This did the job.

public boolean excludeFromRowLayoutVerification(){
return true;
}
