Strange behavior with insert_bottom and insert_top
Reported by pierre | April 15th, 2010 @ 05:00 PM
Hi,
I was playing with Nitrogen 2.0.0 and I wanted to try the insert_top action :
-module (bug). -compile(export_all). -include_lib("nitrogen/include/wf.hrl"). -include("records.hrl").
main() -> #template { file="./site/templates/bare.html" }.
body() ->
[
#link{id=button, text="add a new H1", postback=add_h1}
].
event(add_h1) ->
wf:insert_top(button, #h1 {text="new heading 1"}).
The problem is that each new heading behave like the link.
It seems to happen when we want to insert a new element before or
after a link.
In fact, the new element is inserted INSIDE the link but not before
or after.
I'm totally new to the framework, so maybe i'm missing something...
Thanks
Pierre

Hi Pierre,
I think this is the expected behavior. When you insert_bottom() or insert_top(), you are inserting INTO the element that you identify. If you want to insert above or below, you might try creating a panel above or below and then wf:insert_bottom() or wf:update() into that panel. Alternatively, you might want to request that insert_above() and insert_below() functions are added to the API.

Brian O is correct. You should use insert_bottom and insert_top on a panel (which equals a div).
