View mode can be nullable for some entities

for 2.x vesion

Thanks @r_cheh for reporting this. Is there a way on how this can be reproduced? AFAIKS that method _eca_render_trigger_extra_field is called from 2 places and none of them allows NULL for the display mode.

Once we know, how this was happening what you reported above, we should find out the root of the problem. And if something really dispatches one of the hook where no display mode is present, then we should either define a default value (i.e. default or full) or follow the event that's being dispatched by that method, as that currently also expects a string and doesn't allow NULL.

I hope you can follow-up with this?

Any news on this?
