Categories and primary behavior changed?

Hello,

I upgraded FC to RC4 (r1235) from RC4 (r1209)
Joomla 1.5.26

In the back-end when you create a new item you have to set the type, the title, the category(ies) and now also the primary.

Before if you had only one category, you could skip the primary and it was OK.

Now, if you skip the primary selection, the categories are not saved and then next time you get an error

here is a copy of the notice:
Notice: Undefined index: 0 in /var/www/vhosts/domainnameremovedontheforum/press/administrator/components/com_flexicontent/views/item/view.html.php on line 129 Notice: Trying to get property of non-object in /var/www/vhosts/domainnameremovedontheforum/press/administrator/components/com_flexicontent/views/item/view.html.php on line 129

we notice ! thanks for this return
