[kepler-dev] [Bug 2809] New: - Browser Display actor fails for Mac/Linux

[Glen Jarvis]

Dan,
    I saw your email yesterday for Efrat regarding this bug fix. I  
decided to do a quick test (not very thorough) on the same platform  
where I saw the original problem. All other versions of Kepler were  
removed. I downloaded the nightly build from last night and tested.  
The problem still occurs and now the ImageJ browser also does not  
work. [Unless there was a testing/install problem on this machine; as  
mentioned, the test was done quickly.]

    The platform is the same as before (but details could be included  
again if necessary).

When loading the Image Display (3 example), deleting the ImageJ actor,  
and adding the "Browser Display" actor, the following is seen:


> Reading from the browser - val = false
> 488 ms. Memory: 84596K Free: 21709K (26%)2007-04-04 17:52:51.941  
> java[446] LSOpenFromURLSpec() returned -43 for application (null)  
> path //Users/gjarvis/kepler20070404/demos/getting-started/demos/
> getting-started/species-distribution.PNG.


When reverting to ImageJ (also tested with ImageJ upon fresh load of  
Kepler), the following is seen:

> Error evaluating expression: .//demos/getting-started/
> species-distribution.PNG in .03-ImageDisplay.ImageJ.fileOrURL
> Because:
> problem creating otput file (in attributeChanged method)
>



Stack Trace follows:
