Test file for OLE2 embedding in an XLS file.

Attaching test file.

Unit test code: (there is a tiny amount of our framework in it to locate the
file, should be easily removed.

     * Tests that embedded objects are accessible.
     * @throws Exception if an error occurs.
    public void testEmbeddedObjects() throws Exception
	File file = getDataFile("office/ole2-embedding.xls");
	HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(file));
	List objects = workbook.getAllEmbeddedObjects();
	assertEquals("Wrong number of objects", 2, objects.size());
	assertEquals("Wrong name for first object", "MBD06CAB431",
	assertEquals("Wrong name for second object", "MBD06CAC85A",

Turns out this breaks something else, working on version 2.

Patch version 2

Here's the fixed version... it doesn't break the sheets, and is simpler than
the original anyway.

Patch applied. Thanks for it.

I will not close this bug for the same reason as Bug 43222 - it lacks unit tests.
Please provide at least a unit test for EmbeddedObjectRefSubRecord. 

Also, dropping a line in the HSSF quick guide won't harm.   

Comment 6 Yegor Kozlov 2008-01-24 23:11:21 UTC
Unit tests were added. The bug can be closed.
