Nitrogen nitrogen

Here is a fairly minimal example:

-module(test).
-include_lib ("nitrogen/include/wf.hrl").
-compile(export_all).

main() -> #template{file="./site/templates/template.html"}.

body() ->
    PanelId=wf:temp_id(),
    [#link{text="Add", postback={add, PanelId}},
    #panel{id=PanelId}].

event(click) ->
    io:format("click~n");

event({add, PanelId}) ->
    Id = wf:temp_id(),
    wf:wire(Id, #event{type=click, postback=click}),
    wf:update(PanelId, #link{id=Id, text="Click"}).

In Nitrogen 1.0, if you click Add and then Click, the server prints "click".

In Nitrogen 2.0, the postback is no longer triggered in this case, though I think we would expect it to be.

Instead we can do

event({add, PanelId}) ->
    wf:update(PanelId, #link{text="Click", actions=#event{type=click, postback=click}}).

And it does work in Nitrogen 2.0. The two should function equivalently, though.
