We have serious problems with extbase reflection cache on 7.6 with powermail. Fields from powermail cannot be mapped because the reflection info misses a single field.<\/p>\n

I found that cf_extbase_reflection contains multiple reflection data cache identifiers, but - what puzzles me - is that some classes are contained in multiple of those cache entries<\/p>\n

e.g. ReflectionData_Powermail contains class information for powermail but also our own extension's data. same for fluidpages and fluidcontent, which also have some of our extension classes in their cache info ("reflectedClassNames")<\/p>\n

is this normal?<\/p>\n

how are cache identifiers assigned\/used?<\/p>\n

as I see it, they are initialized per-extension - each extension has its own reflection cache<\/p>\n

but that does not seem to be the problem, although I'd really like to know why this is mixed up sometimes.<\/p>\n

now a different property is missing in the reflection info :confused:<\/p>\n

so we found the problem. We're running Ubuntu 16.04 and have php-redis installed, which depends on ... php-igbinary. The igbinary extension in ubuntu is outdated (https:\/\/bugs.launchpad.net\/ubuntu\/+source\/php-igbinary\/+bug\/1651031<\/a>) and has subtle bugs (https:\/\/github.com\/igbinary\/igbinary\/issues\/114<\/a>).<\/p>\n<\/div>\n\n <\/div>\n
