We have a solution running in v12. Its a robust solution that is heavily trafficed.
Oddly, on one of the machines (running 10.6.8 and FMP 12.2) data is not appearing in a couple of filtered portals. The exact same record and layout on a different machine (running 10.6 and FMP 12.1) the portal data does appear. If we turn the portal filter off the data suddenly does display.
The offending filter reads: tic.LIN_Lines~RentalsOnly::zkf_ItemID ≠ 28286 and tic.LIN_Lines~RentalsOnly::_zkfModel ≠ "BSKT" It is filtering out a specific type of line item and product.
Is there a known glitch? Any one have any thoughts?
When FileMaker patched 12 v1 with fixes in 12 v2, Item #6 was fixing portals addressing an issue where portal filtering failed with the "< >" operator. Any chance this is what is happening with you?
