#332 Asta Lag sign incorrect

[Dave McKay]

Hi again Jon,

Running some more Asta Powerprojects into MSPDI XML, and we've come across another anomaly.

A fairly basic project with links, lags, and constraints, when run through MPXJ into XML, does not show correctly in Microsoft Project due to the lags, apparently, being reversed, i.e. -2400 minutes becomes 2400 minutes, and vice versa.

If XML is saved from Powerproject, and then run through MPXJ into XML, then all appears well.

For some reason, Powerproject copes with both!

Anyway, attached please find (... deep breath ...):

1. The source Powerpoint project
2. The XML saved from Powerpoint
3. The XML saved from MPXJ from the source Powerpoint project
4. The XML saved from MPXJ from the XML saved from Powerpoint
5. A potential patch which works here

Regards,

Dave.

Sorry, forgot the patch!

I had a closer look at this. I think the issue is that I'd taken a naive approach to handling the two lag values present in Asta, rather than actually analysing how Asta maps those values itself when you generate an MSPDI file. I've updated the code so it should behave in the same way that Asta does. This diff also includes the constraint mapping change.

can you give this a try and let me know if it works for you?

Cheers, Jon, that patch gives me the output I'm expecting.

Code now in Git fixes this issue.
