Null pointer exception when reading a complex type from umati server.… #2798

Closed marcschier closed 1 month ago

marcschier commented 1 month ago

… the umati server has a extension object with a complex type. Type id = {nsu=http://opcfoundation.org/UA/Machinery/Result/;i=5008}. This contains something with a variant array that is null though (-1).

Proposed changes

SetProperty should support setting a Array that is null. Therefore, test for null collection (case when length was encoded as -1) before dereferencing ahead of the ToArrray() conversion to Array.
