Hi all,
I have an issue with rendering getting itself into an infinite loop.
I've stepped through the code I can see what's going on, but I don't
want to mess with the core given I don't have a good overview of how
it all fits together. I can consistently reproduce this problem by
doing one thing in my app - a post that adds a row to a database
table.
The odd thing is when I clear the CAKEPHP cookie the issue goes away -
as well as logging me out of my app (i'm using Auth).
Starting at Controller->render Cake renders the view, then it hits
line 347 of view.php (code below) and it skips through a bit more code
back to the start of Controller->render to render the layout. While
rendering the layout it gets back to that same line and again jumps
back to Controller->render to render the layout again - I can confirm
this is what I see in my web browser. The problem is it doesn't seem
to know it's rendering the layout, and it gets into a recursive loop.
One solution might be some kind of a flag to say "hey i'm rendering
the layout already, don't do it again", but it would probably be
better to work out why it does it than just adding a flag.
if ($layout && $this->autoLayout) { // view.php line 347
$out = $this->renderLayout($out, $layout);
I'm using Cake 1.2.0.6311-beta on Windows XP with the WAMP stack (PHP
5.2.5, mySql 5.0.45, Apache 2.2.6).
Any thoughts or help would be appreciated!
Tim
