Random behaviour in DataObject.find( FileObject )

Hi all,

I have the next code:

if (FileUtil.getMIMEType(deviceA20FO).equals("text/a20+xml")) {
     return DataObject.find( deviceA20FO );
} else {
     LOGGER.warn("FileObject MIME-Type: " +
FileUtil.getMIMEType(deviceA20FO) );
     LOGGER.warn("FileObject content: " + deviceA20FO.asText() );
     return null;
}


Randomly, sometimes this returns a good A20DataObject and others returns an
unexpected XMLDataObject.

I check that the mime-type for the FileObject is right, and always executes
"return DataObject.find( deviceA20FO )".

At this point, all depends internally of Netbeans that resolves the
DataLoader for the FileObject mime-type, and returnsa DataObject provided
by the DataLoader.

How is it possible that sometimes resolves the right DataObject and
sometimes bad if always right FileObject mime-type is passed?

Any help is appreciated.
