deserialize UTC datetime string to EDate

hello aranega,

I’m not sure of the property way to use pyecore to deserialize datetime values from an XMI resource. I constructed an XMI resource using an ecore metamodel and set an attribute to datetime.utcnow(). the resource serialized without issue using resource.save() but upon loading the resource using create_resource I get the following error:

>>> resource = rset.get_resource(URI(inFilePath))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/env/lib/python3.5/site-packages/pyecore/resources/resource.py", line 82, in get_resource
    resource.load(options=options)

    modelroot = self._init_modelroot(root)

    raise BadValueError(value, self.feature.eType)
pyecore.valuecontainer.BadValueError: Expected type <pyecore.ecore.EProxy object at 0x10d5c0048>, but got type str with value 2018-06-05 16:15:47.290839 instead

myMetamodel.ecore

...
<eStructuralFeatures xsi:type="ecore:EAttribute" 
    name="documentRevisionDate" 
    eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EDate"/>
...

mySerializeData.xmi

... 
documentRevisionDate="2018-06-05 16:15:47.290839"
...

It also failed to deserialize using a timestamp and timestamp string. please help me understand the property way to serialize/deserialze datetime values.

Thanks for this amazing project,

aranega,

ran pip install pyecore -U and now UTC date strings are deserializing correctly.

Thanks!

I’m glad it works well for you 😃. Thanks again for the report!
