Heres a scenario:

Two “similar” templates embedded in a message with no reset in between.

In template 1 I have a field:

In template 2 I have a field:

There are two fields with identical names, one has an id the other does not.

What are the implications from a dictionary perspective? Are these the same dictionary field or different fields?

Cheers,

Hi Declan,

The id has no meaning in FAST. It can be used for mapping to another protocol above FAST, e.g. FIX where tag numbers would be used.

The two fields in your example will use the same dictionary entry if the templates 1 and 2 use the same dictionary (e.g. the ‘global’ dictionary that is the default).
