[Flow] [Fluid] How can I use dynamic array indexes in templates?

[Alexander Berl]

Hi Pavlina,

the (second) code with the viewhelper in it should work. If the array is
"rendered" in your template, that's most likely due to a syntax error.
Did you include the namespace "my" properly in your template/partial?

Other than that, also regard Bastians suggestion - most of the time
overly complex solutions can be prevented with a different approach.

PS: dynamic array access is already on the wish/todo list:

Regards,
Alexander
