Reading Primavera XML files without WBS nodes?

Primavera allows users to export multiple projects into one xml file when exporting to P6XML but as far as I can tell Aspose Tasks cannot read an xml file that contains multiple projects. Am I right in thinking this (I receive a NullReferenceException when trying to initialise a new Project object with the stream of the P6XML file) or is there a different way to read XML files with multiple project definitions?

Further investigation shows that it may not be to do with exporting multiple projects to one file but that there are bugs when reading a P6XML file. The stack trace shows the following which doesn’t really help unfortunately:


at ​ .Alg(Task , Int32 )
at Aspose.Tasks.Util.TaskUtils.Apply(Task root, ITreeAlgorithm`1 alg, Int32 level)
at Aspose.Tasks.Project.()
at ​ .()
at ​ . (XmlElement , Object , String& )
at ​ .()
at .(Stream )
at Aspose.Tasks.Project.(Stream )

It looks like this could be related to WBS nodes, or a lack thereof.


The simple project I created for testing just has a couple of activities and I didn’t add any WBS nodes; when I added a WBS node and set the activities to be within that node, the project then reads ok. Looking at the xml file that errors I notice that the activities have:


where the xml file that is ok has:

26112

So my guess would be that, looking at the stack trace from my previous post, the parser is passing in the WBSObjectId value and trying to convert it to an integer which is throwing an error as this scenario is not handled?

Hi,

Hi,

Could you please confirm to us if this sample file opens fine in Primavera at your end? We tried opening this file in Primavera P6 R8.3 and it was unable to open this specific file. The error log is as follow:

I’m able to open the file with no errors in Primavera P6 R8.4, I don’t have an install of 8.3 so I can’t check with that version.

Hi,


Could you please help us locate this version of Primaver P6 R8.4 for downloading? We need to test this issue with the latest version of the API and share our feedback with you.
