Legacy Screen - attachment preview IllegalStateException: No suitable methods named for invoke

Hi Mario

We are in the process of migrating our application from platform 6 to 7 and it has a number legacy screens. We use the attachable add on extensively throughout the application and on upgrading the platform we have come across an issue with the attachable add on that we can’t seem to resolve.

We get an ‘IllegalStateException: No suitable methods named for invoke’ when we try to preview the attachment by clicking on the link within the table row. I’ve attached a project which shows the issue.

I have engaged with cuba support and they suggested contacting you directly as the author of the add on for advice. Original post:

Any help would be appreciated.
