Description Wayne Kruger 2015-11-26 05:07:17 UTC
When setting a TableView's Content Property from Dynamic Prototypes to Static Cells a very nondescript build error is present:

1>C:\Program Files (x86)\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(997,3): error :

Changing it back to Dynamic, it builds with no errors.

To reproduce:

Drag a View Controller onto the storyboard, then drag a Table View onto the controller. Set the Table View's Content property from Dynamic Prototypes to Static Cells and Build the solution.

Windows 10

Both the errors and warnings from ibtool are being ignored when compiling interface definition files. Example output which gives no MSBuild errors or warnings: https://gist.github.com/alanmcgovern/5bf873fb06385045cdd3
Comment 2 Alan McGovern 2015-11-27 05:33:42 UTC
Wayne, the error you were supposed to see was `Static table views are only valid when embedded in UITableViewController instances`, so the problem you had was just you were doing something iOS does not support. As such, i reassigned this to the iOS team so they can figure out why the error messages are not being reported correctly.

Hi Alan, Thanks much appreciated!
Comment 4 Jeffrey Stedfast 2015-11-30 16:58:30 UTC
The problem is that we're in a situation where if we show errors reported by ibtool's stderr, we get bug #33706.

If we ignore stderr, we get this bug.

Rock. Hard place.
Comment 5 Alan McGovern 2015-11-30 18:35:26 UTC
The errors aren't in stderr, they're in the manifest produced by ibtool when it finishes. I believe the issue is that if ibtool returns a non zero exit code we bail out before parsing and propagating the errors in that manifest

Or at least that's what I remember from looking into it last week :)

oh, okay. Then that sounds more fixable.
Comment 9 Jeffrey Stedfast 2015-12-01 16:20:00 UTC
Fixed in git master.
