Now I'm wondering if this is a bug somewhere in the pageinit javascript?
Every time the Alerts component renders an individual alert, tapestry uses
the javascript alert function (in alert.js) like so...
1) (from Alerts.java)
javaScriptSupport.require("t5/core/alert").with(alert.toJSON());
I don't see anything wrong in alert.js, it's working like you'd expect.
The problem is this javascript alert function is being invoked TWICE
for each and every "require/with" thing from Alerts.java like I've shown in
my 1) above.
As I've stated, there seems to be no problem in alert.js
>From what I can gather from the javascript call stack,
it might have something to do with double calls from pageinit.js
I am operating under the assumption that
1) alert.js is not broken
2) require.js is not broken
3) jquery is not broken
the weird thing is that the alerts are being displayed the 2nd time in
REVERSE ORDER??
Anyhow, all I really want to know is, is anyone else testing the beta3
seeing this same problem?
Presently it's a bit of a show stopper for me. I was hoping to get this
simple project done today and it's all done but the Alerts issue.
Is this a bug?
Surely someone has either 1) seen it or 2) sees an error in what i wrote,
and can shout me down as a dunce.
Also, did my image attachment make it to the list last time?
I can see why people might be ignoring me as being to vague w/o seeing the
image.
Please and thank you for any forthcoming illuminations.
