I'm attempting to figure out how to make XmlConfig behave properly on an
upgrade. It works beautifully on install and uninstall, but not so well when I
try to do an upgrade.
This is with WiX 3.0.2813.0
Here's a component:
<Component Id="dataservices.php" Guid="MY_GUID">
<File Id="dataservices.php" ... />
<!-- register this file in my-tabs.xml on install:
<tab name="Data Services" enabled="True"
url="subdir/data-services.php" />
-->
<util:XmlConfig Id="MakeDataServicesTab"
File="[xml_dir]my-tabs.xml"
Action="create" Node="element" On="install" Sequence="1"
ElementPath="/my-tabs"
VerifyPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="tab"
/>
<util:XmlConfig Id="DataServicesTabAttrName"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="2"
ElementPath="/my-tabs/tab[\[]not(@name)[\]]"
VerifyPath="[EMAIL PROTECTED]'Data Services'[\]]"
Name="name" Value="Data Services"
/>
<util:XmlConfig Id="DataServicesTabAttrEnabled"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="3"
ElementPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="enabled" Value="True"
/>
<util:XmlConfig Id="DataServicesTabAttrUrl"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="4"
ElementPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="url" Value="subdir/data-services.php"
/>
<!-- remove the line:
<tab name="Data Services" enabled="True" url="subdir/data-services.php"
/>
-->
<util:XmlConfig Id="RemoveDataServicesTab"
File="[xml_dir]my-tabs.xml"
Action="delete" Node="element" On="uninstall" Sequence="5"
ElementPath="/my-tabs"
VerifyPath="[EMAIL PROTECTED]'Data Services'[\]] "
/>
</Component>
--------------------
When I attempt a major upgrade, I get the following output in a verbose log
file:
MSI (s) (C0:88) [12:38:44:773]: Hello, I'm your 32bit Elevated custom action

----------------------
It seems that:
1. On an upgrade, the VerifyPath for the "MakeDataServicesTab" element create
exists, so no no-name node is created. (Repeat THAT five times fast.)
2. The add-a-name-to-the-no-name-node step at "DataServicesTabAttrName" fails
because #1 was skipped.
I couldn't find any way to change the VerifyPath of #2 that would get around
the error message. When I look at the code in XmlConfig.cpp, it seems that the
ElementPath is checked first, and thus the VerifyPath check never comes into
play.
Am I missing something, or is this actually a bug?
Thanks!
