Team, We are upgrading from Olingo 4.2 to Olingo 4.4 and ran into an unexpected change of behavior of the library.
Here is the URL of the API Get /odatav4/school-service/Students?$filter=teachers eq ‘smith,john,mary’ Teachers is of String collection type, we use comma as delimiter and pass in the expression as one String, it uses to work fine in 4.2, but in 4.4, we got the “Collection not allowed.” error. By looking at the source code of 4.4.0, it is due to the new method in ExpressionParser. checkNoCollection Can you please suggest what is the correct format of filter we need to pass in then? thx Erming Tuo PTO 03/18-04/03 LMS software Development Architect SAP SuccessFactors | 2000 Edmund Halley, Reston, VA US +1 703-678-0615 [cid:E0BBB916-1B85-490F-B852-EA52F290EC0D] This e-mail may contain trade secrets or privileged, undisclosed, or otherwise confidential information.
