we have a simple MPP file that contains a single link. This link is missing from the imported apose.tasks structure. Note that we found that opening this file in MS Project 2010 and saving it in the new MPP format created a file that works …
I have managed to repeat the problem on my side (see screen shot below).
I have created a new issue ‘Don’t read task links from MPP file.’ with ID=19419 and linked it to this forum thread. We are going to fix the issue in our September’s official release (end of the September).
Thank you a lot for the information and data sample and sorry for inconvenience.
