Firing segues failing

I have a storyboard.

In this storyboard there is a UITableViewController that uses a custom class, comMasterViewController.

Using the storyboard, I simply control-drag from the UITableViewController to another scene.

A modal segue is created. I change its identifier to "loadingDataSegue".

In my UITableViewController code, I fire this line:

[self performSegueWithIdentifier:@"loadingDataSegue" sender:nil];

I receive:

Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: 'Receiver (<comMasterViewController: 0x1b6290>) has no segue with 
identifier 'loadingDataSegue''

What isn't being hooked up properly?

Thanks for the help

EDIT: I am pretty sure I am linking the TVC, and not any of the subviews. Looking at the storyboard code, I see the following:

<tableViewController storyboardIdentifier="comMasterViewController"
     title="comMasterViewController" clearsSelectionOnViewWillAppear="NO" id="19" 
     userLabel="comMasterViewController" customClass="comMasterViewController" 
     sceneMemberID="viewController">

and at the bottom, as a child tag to <tableViewController> and not to any of its subviews:

<connections>
    <segue destination="UCh-sM-lba" kind="modal" identifier="loadingDataSegue" 
        id="epP-jH-GLZ"/>
</connections>

I had this exact problem(the symptoms anyway) and ElJay gave me the hint I needed. My problem was caused by the TableViewController being inside a NavigationController and it was opened by an alloc init and push using the NavigationController. This was the reason [self performSegueWithIdentifier] didn't work. Even more, this was also the reason the segue I created from the cell didn't work, so now I don't even need the [self perform...] part, just prepareForSegue and everything works like a charm.
I would have replied this to ElJay, but for some reason I can't. All I could do was give him a vote.

Make sure you didn't drag that Segue from a TableView Row or UIButton and instead from the VC itself. If you are in doubt, delete the segue and connect it again. Also check for typo's (including case) if that doesn't solve your issue.
