[wix-users] Cannot overwrite property in Custom Action

[Matsumoto Chihiro]

Hello:

I (Newbie of Wix) posted a question in Stackoverflow about a property which I want to overwritten by BrowseDlg...No answer from gurus in Stackoverflow.

Probably for an elementary problem.... I have failed (still commandline output is
"C:\SxS\" which is not overwritten), but tried to keep my motivation up.... If I faces a simple test which gurus consider it should be solved by myself, would you teach me...?

1:Is it a simple bug problem, or something difficult to access the overwritten value?

2:If it is correct former in question 1, I want to know how to debug the property value in install sequence.... msiexec /i {msi} /lv* (Sorry for Japanese Characters....) told me something overwritten the "SxSFolder" property, but result is still not overwritten....
