findAndGetOFStringArray - the string is not cleared

[Alexander Fedotov]

Hi!
Here is the piece of code:

***************
DcmDataset *pDataset = m_pDcmFileFormat->getDataset();
OFString strTagValue;

pDataset->findAndGetOFStringArray(TagKey1, strTagValue);
cout << strTagValue.c_str(); // the value is correct, for example "bla-bla-bla"

pDataset->findAndGetOFStringArray(TagKey2, strTagValue);
// returns "good", but the attribute value is not set, it has a zero length
cout << strTagValue.c_str();// the value remains the same, "bla-bla-bla"
***********************

So one has to add strTagValue.clear() before the second call
of findAndGetOFStringArray();

If it is "as designed", I think it has to be documented somewhere, because it may cause "bugs" in the application.

Or I missed something?

Best Regards,
Alexander.

Thank you for the report. There seems to be a bug in DcmElement::getOFStringArray(). We'll fix this for the next release.
