Isolated the cause of error in the following:

I called this Class here:

```auto
<Blinker MyColor="{statColor_Server}" Width="10" Height="10" TimeOn="0.2" TimeOff="1" Frequency=".5" >
   <Text Color="{statColor_Server}" Margin="0,12,0,0" FontSize="12" TextAlignment="Center">Server</Text>
</Blinker>

```

variable is set here in JS with the following line:

```auto
 var statColor_Server = Observable("#32CD32");

```

Calling it in:

```auto
  <Text Color="{statColor_Server}" ......

```

works fine

but if passed as property in the Blinker class, the error occurs.

Is there any more info/logging in the Fuse Monitor like the screenshot requests?

@mojo: This sounds like a bug, but I’m unfortunately unable to reproduce this using the current release. What release are you using? Also, there’s a chance that I’m somehow missing some detail required… Could you share your project with us so we can try it out?

Hi Bent here’s the log [http://pastebin.com/NnWRbThM](http://pastebin.com/NnWRbThM)

@Erik

I’m on 0.24.0 (Latest i believe). I’ve gone through it over and over, I just can’t make sense out of it.

Sure, I dont mind sharing the project, but it’s really messy…

To help a bit, I created a new project with just that part demonstrating the issue. Using the following project files I can confirm that I am still getting the issue as reported

[https://drive.google.com/file/d/0B3jZ8tb0rlu7X3YyX2NnYlo5YkU/view?usp=drivesdk](https://drive.google.com/file/d/0B3jZ8tb0rlu7X3YyX2NnYlo5YkU/view?usp=drivesdk)

Please jump to Line 103 and see my comment

Thanks!

Just to post an update, this issue has been found and fixed. It’ll hopefully be out in a release in the near future.
