No, that is wrong. "If no index is given, the first value will be returned.” [1]

So if I'm not mistaken, then I don't understand what the problem is here? Correct me if this is wrong.

When the AVP is already populated, these functions simply push on the end. This may be an implementation decision, but it is certainly not intuitive or what I expected. I am currently using the same workaround of clearing out the AVPs prior to each DROUTING module call that populates them.

Then to get the gw id pushed by route_to_gw() I have either to use the avp index (e.g. $avp(dr_gw_id)[1]) or I set $avp(dr_gw_id) to null before calling route_to_gw() (which is what I am doing now).

But how did you retrieve the gw_id from is_from_gw, did you use an explicit index?

After some investigation I noticed that earlier in my script I was calling the is_from_gw() function with the 'i' flag which also pushes the gw_id to the avp and this was the value I was seeing in my avp after calling the route_to_gw(). By debuging with the avp_print() function I could see that the route_to_gw() does not pushes the gw_id to first index of the avp, but to the end of it. Any reason for that or is it a bug?
