CPE GUI and CDE do not distinguish empty array from null
--------------------------------------------------------
Key: UIMA-107
URL: http://issues.apache.org/jira/browse/UIMA-107
Project: UIMA
Issue Type: Improvement
Components: Eclipse plugins, Tools
Reporter: Adam Lally
Priority: Minor
If editing a component descriptor by hand, a multi-valued parameter can either
be set to an empty array or to null. However, the CDE and the CPE GUI both
present a list widget for these parameters, which does not provide any way to
distinguish between the two.
An empty array is specified in the descriptor by:
<nameValuePair>
<name>paramName</name>
<value>
<array></array>
</value>
</nameValuePair>
Whereas a null is indicated by not specifying including a <nameValuePair>
element for the parameter at all.
