Hello, I am getting null pointer exception when I try to do a search using 4 levels like "locate.locateTag.tag.description".

locateTag and tag are complex objects

thank you

Could you refer to the sample test case? I use "projects.projectTag.localTag.description=='Local Tag 1'" and it works fine.

fabianotorresrj commented 3 years ago

Thanks for answering. Just for the record, I was using version 5.0.16. With version 5.0.17-SNAPSHOT it worked. I would like to know the expected date for her release. Thank you very much for your attention and congratulations on your work.

Actually, no code change since 5.0.16 excepted the test cases. By the way, I've created V5.0.17. Thanks for your support.
