I just downloaded and installed SproutCore on OS 10.5.3.
I found a way to very easily produce the problem:
1) Generate a new example app as per http://www.sproutcore.com/documentation/getting-started/
2) Start the server, and all is well UNTIL ...
3) Replace the contents of body.rhtml with this:
<% content_for('body') do %>
<img src="/fubar.gif" />
<% end %>
where "/fubar.gif" can be just about anything so long as the image
does not really exist.
4) Refresh the web page, see the stack trace.
If you point it to an image that does exist, then the stack trace does
not occur.
I am considering rewriting an app using SproutCore. I hope this is
example is not indicative of an overall fragility of the framework.
Best regards,
Tom
