Property Injection for NRules within ABP

问题 I am using ABP Boilerplate 6.0 and have integrated NRules with our platform. I am able to get the rule below to work, but the issue is that I cannot use the injected ‘_questionResponseRepository’ within the rule condition, because only after the rule criteria are met, does the resolution of dependencies take place. I would like to use ‘_questionResponseRepository’ to get from the database a list of keywords and use those words in the Rule match condition The Calling code public

But I can't seem get a match on a collection, single variables do work. The
