I keep getting this error in Eclipse: “The method getRaType(DataType) from the type RaType refers to the missing type DataType”.
There are several versions of this, but the first part is always one of my declared types and the ‘missing type’ is always a Knime type, usually DataType.
The code all compiles and runs perfectly. Then I make some minor unrelated change and this error pops up. I have found that the Eclipse Project|Clean makes it go away again, until the next time. Reloading the Knime target seems to work too.
Any idea what might cause it?
