Viewobject rows don't exist when creating a lot of rows at once

Question

Hello,
I'm creating a lot of rows at once in a viewobject. Let's say between 100 and 700 rows. After that, I commit the transaction. After the creation of every row I do a postchanges().
When this is all done, a xml file is sent to another server and returns the same file with a bit more information. That file is parsed and every row will be searched in the Viewobject but then they don't exist!
When I try this with a couple of rows, 10 or something, everything goes well. Is this a known problem or am I doing something wrong? I don't want a commit after the creation of every row because sending must succeed before saving them.

Answer 1

No off course.
I hoped that more people have problems with inserting a lot of rows at once. The code is quite simple, it looks a bit like this:
for ( about 500 elements )
Row row = voIterator.createRow();
row.setAttribute("...", "....");
voIterator.insertRow(row);
getDBTransaction().postChanges();
getDBTransaction().commit();
