Description

Inside a pipeline, the "Set field value to a constant" transform throws an error: 

 

RuntimeException: Error create instance of transform data: null. Root cause: IllegalAccessException: class org.apache.hop.pipeline.transform.BaseTransformMeta cannot access a member of class org.apache.hop.pipeline.transforms.setvalueconstant.SetValueConstantData with modifiers ""
 

In the attached pipeline, starting the pipeline via the "play" button yields "Idle" running status, see attached screenshot.

Trying to use "Preview output" throws an error message, see attached.

Data grid without this step works normally.

I could not find any workarounds using this transform, it seems completely broken.

 

How to reproduce:

• open the pipeline
• try to run it via "start button" ==> execution remains in "Idle"
• try to "Preview output" on "Data Grid" or "Set field value to a constant" transform ==> error is thrown
• remove the "Set field value to a constant" transform ==> everything works flawlessly
