Moving Feature to a Fragment Throws Error - wix

Question

I am new to WiX, but I have one issue that I can't figure out. I have the following code which "installs" fine (basically it just adds a text file to the Program Files folder).
<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Product Id="*" Name="WixTemplate" Language="1033" Version="1.0.0.0" Manufacturer="My Company" UpgradeCode="d7c4cfc2-4e50-4002-9273-e900112e2b03">
<Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" />
<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
<MediaTemplate EmbedCab="yes"/>
<Feature Id="ProductFeature" Title="WixTemplate" Level="1">
<ComponentGroupRef Id="ProductComponents" />
</Feature>
</Product>
<Fragment>
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLFOLDER" Name="WixTemplate" />
</Directory>
</Directory>
</Fragment>
<Fragment>
<ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
<Component Id="TextFileComponent">
<File Id="FooTxt" Source="foo.txt" />
</Component>
</ComponentGroup>
</Fragment>
</Wix>
However, if I move the Feature section to its own Fragment, it compiles fine, but when I run it with logging, it fails with an overall "Installation success or error status: 1603" and the first error value of 3 indicating "Note: 1: 2205 2: 3: ActionText" meaning that the ActionText table was not found.
Here is the code that fails to install:
<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Product Id="*" Name="WixTemplate" Language="1033" Version="1.0.0.0" Manufacturer="Blue Ribbon Technologies, LLC" UpgradeCode="d7c4cfc2-4e50-4002-9273-e900112e2b03">
<Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" />
<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
<MediaTemplate EmbedCab="yes"/>
</Product>
<Fragment>
<Feature Id="ProductFeature" Title="WixTemplate" Level="1">
<ComponentGroupRef Id="ProductComponents" />
</Feature>
</Fragment>
<Fragment>
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLFOLDER" Name="WixTemplate" />
</Directory>
</Directory>
</Fragment>
<Fragment>
<ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
<Component Id="TextFileComponent">
<File Id="FooTxt" Source="foo.txt" />
</Component>
</ComponentGroup>
</Fragment>
</Wix>
So what's special about the Feature section that it can't be a fragment where Components and Directories can?

Answer 1

Nothing in your Product references the Feature. WiX won't link in a Fragment unless something references a resource in it. Add a FeatureRef to your Product to pull in the Feature which will in turn pull in the ComponentGroup which pulls in the Component.
