#724 Get Error Expanding Points Folder

Ricky Villa Valle Wed 24 Jul

When navigating to the points folder under an equip, we get the below error when trying to learn the points. Not sure what it means.

Setup: AX 3.7 with nhaystack module 1.3.0.

haystackLearn(@247188dd-1f68425f, "slot:/Drivers/BacnetNetwork/VAVs/Rtu1/VAV_01/points")

proj::EvalErr: Func failed: haystackLearn(Obj conn,Obj arg); args: (Ref,Str)

haystack::CallErr: java.lang.NoClassDefFoundError [eval:1]

conn::connAppLearnLoad (eval:1)

=== Remote Trace === java.lang.NoClassDefFoundError
