When Generating a new XXXTablePage, and we already have a XXXForm, a java.lang.NullPointerException exception is thrown and the method signature of getXXXTableData is not inserted in the existing services files.
The same exception occurs when generation XXXForm with an existing XXXTablePage, and the methods signature prepareCreate, create, store, load are not inserted in service files.
Environnment: MAC OS Mojave
JDK 1.8 (Also same exception with openjdk 1.8, 11 and 13).
