Here's my IssueController located at : /protected/controllers/IssueController.php

the Issue View Page located at : /protected/views/issue/_form.php
There seems to be a big problem at the getUserOptions located on line 45 that indicated this:
$model->project->getUserOptions()

Is there an error you get or what's the exact problem?


What looks strange to me is this call:
$model->project 

Usually you call model relation this way, but there's not such relation at the model. You have $_project defined at the controller, so, if you have getUserOptions() method at Project model, then, I suppose you should rather have (not tested) something like
$this->loadProject()->getUserOptions()


$this stands for IssueController here.

Hope it'll help. Or post the error you get first of all.

So yes, seems I was right about how you should call users options. Pls take a look at my previous message.
