[Tikiwiki-devel] session problem

[Burghard B. <bu...@ch...>]

when coding a small wikiplugin I got a strange session problem:
I set one session-variable at a single place to a value (e.g. 45). at  
the next run of the wikiplugin code the session-variable has a value  
of 53.
at various places in the code (tiki-information.php is handy) I spread  
print statements to log the values of this variable if the print  
statement is at specific places, the value of 45 remains until the  
next run of the wikiplugin-code if I place it at a line behind this is  
changed.
greped for another session-variable with the same name (pagemenu) but  
I found none of it (some occurences of another variable with the same  
name exist). for that reason I renamed my variable without getting rid  
of that strange behavior.
I copied the database to my developement installation. here everything  
is working fine.
It seems to me like a memory out of bound usage error.
Is there anything I have to take into acount when dealing with  
tikiwiki and sessions?
sincerely,
burghard.
