I am getting following error for pet/ct studies in webstation.Its only for pet/ct studies.Studies of other modality is shown properly.

In webstation a message box is shown telling an unexpected error has occured on the server.

Any idea what is it?

Exception has occurred

Can you tell me:
1. What version of ImageServer you are using?
2. Windows OS you are using?
3. 32 or 64 bit?

 

Its 32 bit

Windows os is XP

Imageserver version is 1.0.0.0

Value of '-2147483648' is not valid for 'red'. 'red' should be greater than or equal to 0 and less than or equal to 255.

This is the error i found when i debugged the code and its firing from RunCommandPump method of ClearCanvas\ClearCanvas Image Server\Web\Services\WebSynchronizationContext.cs.

Sorry,Image server version is

Version: 2.0.12655.37768

Not sure what you've done to the 2.0 code to get a Webstation on there, but my first thoughts are you either have something going on with your code or you have an image that's not quite right.

You can try:

1. Open your image in the Workstation (not your browser) to see the image displays correctly.

2. Install the ImageServer + Webstation 3.0 Pre-release version and see if the image displays correctly.

Are you building the ImageServer from code? 1.0.0.0 is the version a lot of the assemblies are if you build from source.
