DataDirector execute Truncate Before Import every 100 records ?

[betterapp]

We have such class definition:

DataPort mapping

We made some changes to allow multiple assigment:

And we enabled "Truncate before import" action here:

Now we want import XLS file with 314 records in it into Products field.

But DataDirector Truncate Products field every 100 records so in the end we have
14 rows not 314 under Products fields

DataDirector: 3.7.77

Should be fixed in later versions. Can you please try if the problem still exists in 3.9.*?

The problem is that we have other project that use DataDirector 3.9
and somehow we see duplicate objects under Advanced Many to Many relation fields

For example:

We have API dataports that create and update product data.
During some execution new product was created with relation to Contributor object with different metadata.
Something like:
123 - Contributor A Name - Role: Author
123 - Contributor A Name - Role: Ilustrator

Next time when we update the same object with different dataport
in some conditions we return $params['currentValue'] for Contributors field.

After long time we discovered that some Products have duplicated value there:
123 - Contributor A Name - Role: Author
123 - Contributor A Name - Role: Ilustrator
123 - Contributor A Name - Role: Author
123 - Contributor A Name - Role: Ilustrator
123 - Contributor A Name - Role: Author
123 - Contributor A Name - Role: Ilustrator
123 - Contributor A Name - Role: Author
123 - Contributor A Name - Role: Ilustrator

and we saw products with 50k+ of such entries.

I can not confirm the problem occurred during using 3.7, 3.8 or 3.9 version.
I did not had time to researching what is going on with it yet.

Maybe the problem is with

return $params['currentValue'];

for the filed.

That is why I am not sure to update DD to 3.9 for other client.
