I have a repeater that contains a flex content field and one of the layouts in the flex content field contains a repeater. Everything works as expected and I get no errors. The exception to this is that the sub fields in the final repeater are not being rendered – regardless of the type of field used – the result is always false.
As you can see the final repeaters sub fields are blank (starts line 77). Bit weird this as the database shows the results as being saved (see same gist – line 205 onwards). The values post ids from a post object field.
