Call to a member function add() on a non-object in some files

[mlof]

Hello, I am installing sugarcrm SugarCRM 5.2.0j PHP ver 5.2.6 MySql ver 5.0.67
On the prepare stage everything goes fine, but when creating database stage begins I catch the following fatal error messages on some files like
"function add() on a non-object in SugarBean.php"
"Call to a member function add() on a non-object in /usr/local/share/SugarCE-Full-5.2.0j/install/populateSeedData.php"

I`ve just commented out the strings where errors have arrised.
In populateSeedData.php it was "$email->contacts->add($contact->id);" string
In SugarBean.php it was "$this->$rel_name->add($this->$id); string "
But allways error with add() function.
Is something wrong with my system or it is "Sugar" Bugs?

It seems the relationship between emails and contacts had not been created.
Try erasing database and installation and try again.

I am having a similar problem but I am currently using 5.5, I'm trying to create a one-to-one relationship between two modules. I can create the relationship fine, but when I go to test it and assign one module to the other and click "Save" it throws the message:

Fatal error: Call to a member function add() on a non-object in /var/www/sugardev/dev5.5/data/SugarBean.php on line 1896

My sugarcrm.log file also outputs multiple times:
Tue Jan 5 11:39:56 2010 [402][1][FATAL] Error fetching relationship from cache tn_templates_tn_groups

I have tried to Rebuild relationships and Rebuild DB, but nothing seems to work properly.

I've also tried completely deleting the modules and package, as well as any information regarding these modules in the custom directory, to no avail. I've also deleted the upgrade_history record and the cache/upload/upgrades/module information that was mentioned in one of eggsurpluses posts.

If anyone has any ideas, I would be very grateful, I've been stuck on this problem for the past few days.



Thanks,

Brian

mv cache cache.bak
mkdir cache
