[jopendocument] OfficeAutomaticStyles cannot be null

[yambo]

Hi,

when I run java org.jopendocument.sample.SpreadSheetCreation, this
creates a file temperature.ods.
running  java org.jopendocument.sample.SimpleViewer and selecting
temperature.ods gives :

content.xml : ignoring :office:document
Dump attributes:
Exception in thread "main" java.lang.IllegalArgumentException:
OfficeAutomaticStyles cannot be null
        at org.jopendocument.model.OpenDocument.init(Unknown Source)
        at org.jopendocument.model.OpenDocument.loadFrom(Unknown Source)
        at org.jopendocument.model.OpenDocument.loadFrom(Unknown Source)
        at org.jopendocument.sample.SimpleViewer.main(Unknown Source)


Am I missing something ?

regards
