Ok, it was my fault. In my ZF View Helper I've used wrong conditions.
Never the less, mistery behaviour - i think on parsing side the object
was missed.
Sorry for the wrong alarm ;)

For example: (in view script)
<?php
$obj = $this->{$index.'_heading1'};
$text = $obj->text;
var_dump($text);
?>
ends in an error ... on non-object ...
<?php
$obj = $this->{$index.'_heading1'};
$text = $obj->text;
die(var_dump($text));
?>
returns the right string
... this can't be a fail on me =/ ...
All objects will be loaded correctly.
But if i try to access the object property it fails.
Please Email me on solution, i stucking in this problem.
Thanks in Advance

It's very confusing. I get ... on non-object ... error, too.
Im Using Ubuntu and it seems that ubuntu automaticly uses the suhosin
plugin.
Maybe the error is in this part of software.
The Object will be returned correctly.
My Object is of type Zend_Db_Table_Row_Abstract.
If i use var_dump($obj->text); it will return the text.
If i use gettype($obj) it will return the class name.
But if i try to use this in the view script i receive this confusing
error.
No solution =/

I'm experiencing the same problem using php 5.3.2 under Ubuntu Lucid
(5.3.2-1ubuntu4.2).
This is really annoying since the isset() function is supposed to check
whether the object exists or not, so the error makes so sense for me.

Please try using this snapshot:
http://snaps.php.net/php5.3-latest.tar.gz
For Windows:
http://windows.php.net/snapshots/
5.1.2 is an extremely old version of PHP. Please try again with a
current version.
FWIW, I can't reproduce this with 5.2.10-whatever-Ubuntu-ship or 5.3.1
-- the only notices are to do with the use of the undefined $key
variable as an array index, which are valid. The expected output is:
$not->set->variable
isset false
empty true
------------------
$not->set[$key]
Notice: Undefined variable: key in /tmp/test.php on line 11
isset false
Notice: Undefined variable: key in /tmp/test.php on line 13
empty true
