Subject Re: Bug with multi-valued properties when exporting repository content?
Date Tue, 15 Nov 2005 10:54:21 GMT
Ok Stefan.

But I think that the problem happens also with more than one property, i.e.
:

Property p1 = node1.setProperty("someName", new String[]
{"someValue1","someValue2"});

I don't know if your explanation covers this case.

Regards.

Martin
