Not possible to pass WixBundleProviderKey variable to msipackage - wix

Question

I have a problem with the burn built-in variable WixBundleProviderKey. I need to pass the value of this variable to an msi package. My problem is that the value of this variable is not evaluated, and the msi will only receive an empty string. I have tested with other built in variable and it works as expected.
Any ideas why this is not working? Is there a workaround?
Example:
<Fragment>
<PackageGroup Id="Test" >
<MsiPackage Id="Test"
DisplayName="Test 4.10.0002"
DisplayInternalUI="no"
Visible="no"
SourceFile=".\Template\ProductsToInstall\Test\Test 4.10.msi"
Name="Test\Test 4.10.msi"
Cache="yes"
CacheId="Test 4.10"
Compressed="no"
Vital="yes"
Permanent="no">
<MsiProperty Name="BURN_WIXBUNDLEORIGINALSOURCE" Value="[WixBundleOriginalSource]" />
<MsiProperty Name="BURN_COMMONAPPDATAFOLDER" Value="[CommonAppDataFolder]" />
<MsiProperty Name="BURN_WIXBUNDLEPROVIDERKEY" Value="[WixBundleProviderKey]" />
</MsiPackage>
</PackageGroup>
</Fragment>
Thanks in advance

This is a bug that should be fixed in v3.10: http://wixtoolset.org/issues/4630/

Try this trick.
You can create new variable with name "BUNDLE_KEY" (for example)
<Variable Name="BUNDLE_KEY" Type="string" Value="[WixBundleProviderKey]" />
And then apply this variable to MsiProperty:
<MsiProperty Name="YOU_PROPERTY_IN_MSI" Value="[BUNDLE_KEY]" />
I hope it will help you.

Not exactly the answer to the question, but maybe it helps.
In my case I needed to pass the value of WixBundleProviderKey variable to msi to get the full path to my BundeSetup.exe, which is cached in "CommonAppDataFolder\Package Cache\WixBundleProviderKey" directory. To do that I created a property with FileSearch element in msi, providing to the full path of the searching file.
<Property Id="BUNDLECACHEPATH">
<DirectorySearch Id="BundleDirSearch" Path="[CommonAppDataFolder]Package Cache" Depth="1">
<FileSearch Name="BundleSetup.exe" />
</DirectorySearch>
</Property>

Seems like the only way to pass WixBundleProviderKey value in Standard Bootstrapper Application is to pass it through InstallFolder variable:
<Variable Name="InstallFolder" Value="[WixBundleProviderKey]" />
The other solution is to pass it inside the path to the bundle setup temp files through DirectorySearch element variable:
<util:DirectorySearch Path="[TempFolder][WixBundleProviderKey]" Variable="KeyPath" />
<MsiProperty Name="BUNDLE_KEY" Value="[KeyPath]" />
The way to get WixBundleProviderKey in your msi from [BUNDE_KEY] property value is to implement C# Custom Action using String.Substring() method. And put it inside InstallUISequence before AppSearch event - if you want to use the obtained value inside RegistrySearch element.
