Thanks for the answer.
The custom action was placed before CostFinalize, I didn't change this
position.

I'm not sure I understand this... could you please explain?
>> It is all a matter of your position in your sequence
I'm populating the Directory table before CostFinalize, which should be ok I
think - the directories are not resolved by this time, right?

Changing the database view will change all future queries into that
database. Changing the current property set (which is gradually built up a
query at a time) will change all future uses of that property.
It is all a matter of your position in your sequence (and where the actions
before and after you are getting their data from).

Subject: [WiX-users] MsiViewModify vs. MsiSetProperty
Hello MSI gurus,
I've faced with an interesting issue, which is now a kind of academic
interest for me.
I had to modify the MSI tables from an immediate custom action using DTF. I
was using View.Modify method with InsertTemporary option, as it is the only
way to "change" the MSI database at runtime. All the tables required were
addressed by this technique, including Property.
However, I mentioned that my custom action behaves incorrectly. I've been
setting a property containing the disk root (e.g. D:\) and then referenced
that property from Directory table. But in the log file that property fell
back to a disk root with the most of free space (as if the TARGETDIR wasn't
set).
When I changed the property set operation from View.Modify to
session["PROP_NAME"] = "D:\", everything started working correctly.
So, my question is what's the difference between MsiViewModify and
MsiSetProperty? And are there any recommendations where to use each?
Thank you.
