Thanks a lot @gcliff, the log is really useful. For info what this says:
ImageAttachmentHandler#supportsView(String) does not exist, which is true. It’s the appended “
Z” that says that the method is not found.
Turns out that this will be fixed as part of ATT-38. Just waiting for @reagan to merge my PR to his repo.
The upcoming fix is here actually. In plain English:
AbstractAttachmentHandler#supportsView(String view) was added, so all “Attachments handlers” (those that extend
AbstractAttachmentHandler) will expose that method.
Would be great if you could test again once ATT-38 is merged.
