SpEL rule cannot handle 2 facts in the same rule #323

Closed guidoipsy closed 3 years ago

guidoipsy commented 3 years ago

Hello, I cannot make this rule work, I don't know if I making something wrong.

_.when(" #{ ['userTraitService_lifecycle'].?[ id == ['currentCycleGBP'].id ].size() > 0 }")

If I remove the ['currentCycle_GBP'].id and hardcode it with a valid id, it work, also ['currentCycle_GBP'].id is used in another rule with out problems.

But the general idea is:

userTraitService_lifecycle is a list of objects
currentCycle_GBP is a simple object
The general idea for the rule is that, there is at least 1 element with the currentCycle_GBP.id return true
All facts element can be accessed individually but when I put them in one rule it evaluation fails

This seems like a SpEL syntax issue. Please provide a minimal example that reproduces the issue or a failing unit test to be able to help you.
