[wix-users] WiX 4.0 Errors and Current / Future State Questions

Two things:

1. We are in middle of WiX v4.0 development. Plenty is still broken. Focus will finally shift from v3.x to v4.x after v3.10 is released.

2. AFAIK, no one plans to all the work to make Votive SxS so while the rest of the tools will install SxS Votive will likely have to in place upgrade.

Subject: [wix-users] WiX 4.0 Errors and Current / Future State Questions

I maintain a certain open source project (http://iswix.codeplex.com)  that currently works with WiX 3.x.  I'm currently going through the code base and refactoring it to be compatible with WiX 3.x and WiX 4.x.  In doing so, a few questions have come up:

1) WiX 4.x and 3.9 installed side by side however WiX 4.x votive took over.   I have project templates for 3.x and 4.x and for now I'm thinking that if I detect 4.x I should install the 4.x templates otherwise install the 3.x templates.  Is this correct or will there eventually be an ability to say File | New | Project and select either 3.x or 4.x compatible projects?

2) After doing my refactoring I got light errors in my wxs.  Wanting to rule out that my project templates are buggy I reproduced these errors using the WiX provided project templates.  They are as such:

a) Adding a UIRef to WiXUI_Advanced, WiXUI_FeatureTree, WiXUI_InstallDir or WiXUI_Mondo generates the error:

Error '.', hexadecimal value 0x00, is an invalid character. SetupProject2 light.exe

b) Adding a UIRef to WiXUI_Minimal generates the error:

Error Duplicate symbol 'WixAction:InstallUISequence/WelcomeEulaDlg' referenced by C:\agent\_work\335d34b3\wix4\src\ext\UIExtension\wixlib\WixUI_Minimal.wxs(60). This typically means that an Id is duplicated. Ensure all your identifiers of a given type (File, Component, Feature) are unique or use an access modifier to scope the identfier. SetupProject2 C:\agent\_work\335d34b3\wix4\src\ext\UIExtension\wixlib\WelcomeEulaDlg.wxs 54

Now I could just comment out my UIRef for now but a bigger show stopper for me is:

c) When I add a Merge element I get an error message saying it doesn't belong to a feature (as it should).  However when I add the MergeRef element to the feature I get the error:

Error Value cannot be null. SetupProject2 light.exe 0

So overall, I'm wanting to adapt my toolset to support 4.x so that a 4.x user can use my toolset and so that a user already using my toolset can use 4.x.   Am I just too early?    Are these issues to be expected?
