Issue with the user's Role

Hi,

I have seen that when a user have the project Leader role, he sometimes can't have access to the cost and work of its project. And it depends of the user.
This issue  appears when the project selector is set to "All Projects"

After checking a bit the code in ObjectDetail.php, I have seen that the defaultProject variable is set to the first project of the user even if he is only team member in it, and the permission of this project seemed to be used when displaying the selected project.
By removing the line "$defaultProject=$firstId;" it seems to resolve the permissions issue but may add other trouble, but I haven't thoroughly checked what exactly the code does.
What are your feeling about this issue ?

Regards
