Implementing BackfilledDataListener

[DGDario]

Hi, in my indicator if I try to implement the BackfilledDataListener the export works correctly but when I import the jar file it doesn't shows the indicator. 

If I implement the HistoricalDataListener it works correctly.

Where is the problem?

Thank you

I've found this error in log file:
java.lang.RuntimeException: java.lang.NoClassDefFoundError: velox/api/layer1/simplified/BackfilledDataListener

My bookmap version is 7.2.0 build 9
