             Bug #: 5595
           Summary: GetMetadata Menu doesn't work in eml actor when it
                    handles local eml document and data file
    Classification: Unclassified
           Product: Kepler
           Version: trunk
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: actors
        AssignedTo: barseghian at nceas.ucsb.edu
        ReportedBy: tao at nceas.ucsb.edu
         QAContact: kepler-dev at kepler-project.org


Here is a segment of an eml from a kepler user:

*******************************************************************************
But another thing that would be nice does not work even with this valid eml 
from you. 
There is an option when I right klick on the eml2dataset actor "get metadata" 
which normally should display the metadata as morpho does for example. Any 
ideas about that? When I use this option the following happens.

In the first time it does nothing when i klick on that menu point. When I 
klick on it a second time kepler throws an error. The last lines were:

----------------------------------o
[null] version = 2.3
     [null] getNamespace - NAMESPACE attr is null.
     [null] Exception in thread "MetaData null" java.lang.NullPointerException

     [null] 600 ms. Memory: 333568K Free: 190730K (57%)
----------------------------------o

This is reproducable. Klick once nothing happens. Do it the second time and 
Kepler throws the error above and freezes the UI.

Best regards Claas
