[Phrame-devel] phrame errors vanishing?

[Jason S. <jsw...@ya...>]

I am having a problem with the applicaiton I coded using phrame.  I was working
fine, with 4 model classes, 4 form classes, 7 actions and 5 view.   I am in the
process of:
a) adding two new views and assosiated actions and
b) changing over to our PHP coding conventions (for my applicaiton, not for the
libraries - but it does involve changing things like the names of global
variables in my application like the $mappings array).

Suddenly, the application started clearing the _ERRORS session object.  It was
not undefined or missing, but rather a Stack object with 0 items in the
_elements array.

During debugging, I put the following code into the
ActionController::_processForward method:

$redirect = $actionForward->getRedirect();
$path = $actionForward->getPath();
//debug code starts here
$err = &$_SESSION[_ERRORS];
$s=urlencode($err->Peek());
$err->Push('this is a test from inside ActionController::_processForward');
$_SESSION['errors2'] = &$err;
if (!$redirect) {
	header("Location: $path&redir=$s");
...

the redirect ends up going to a url that looks like:
admaint.php?view=usr&redir=Please+add+a+comment+to+at+least+one+user.

Note the redir parameter indicated there was something to Peek at in the $err
to begin with, even prior to adding the additional item.

I placed the following code at the top of the redirected script, before
anything is even included in the script:
if (array_key_exists('redir',$_GET)) {
	//include enough classes to make the error object valid in the session
	require_once('../phrame/util/Object.php');
	require_once('../phrame/util/ArrayList.php');
	require_once('../phrame/util/Stack.php');
	session_start();
	print "<pre>appl errors:\n";
	var_dump($_SESSION['_errors']);
	print "copied errors:\n";
	var_dump($_SESSION['errors2']);
	print"</pre>";
}

The resulting output from this script is:
appl errors:
object(stack)(1) {
  ["_elements"]=>
  array(0) {
  }
}
copied errors:
object(stack)(1) {
  ["_elements"]=>
  array(2) {
    [0]=>
    string(42) "Please add a comment to at least one user."
    [1]=>
    string(60) "this is a test from inside ActionController::_processForward"
  }
}


How can the original application errors vanish from the session during the
redirect?!?

Any insight would be much appreciated.

Thanks.

Jason
