as i see my problem is related to the version differences also, like for many of us. i was also following the book and the code was not working at Chapter 6: Returning back to the owner and requester dropdowns, page 119. when clicking on create issue at project 1 it gave me this error:
CException IssueController contains improperly nested widget tags in its view "C:\wamp\www\trackstar\protected\views/issue\_form.php". A CActiveForm widget does not have an endWidget() call.
i noticed that there are differences between the sample code and what gii has generated. with the sample code it is working, but i don't really understand the differences and i believe gii was not generating the code to be downgraded back to 1.1.2 so i would be very happy if someone could explain the differences regarding to this section of this chapter, and so i could actualize the book code to the present release version 1.1.5.
