Great thanks for the reply Mike, that makes sense.
So could this be classified as a bug in heat.exe? It sounds like heat
should be limiting the Component ID to a length of 35 for merge modules?
Aka when the "-template:module" flag is used.
I did a search through the bugs database for heat and component but
found no bugs.
I'm a newbie here so how does one submit a bug?
Thanks again
Jimbo

LGHT1076
Components in merge modules have the package GUID appended to the
component ID so there isn't a clash if the same component ID is used in
multiple merge modules, and no clash between the merge modules and the
main installer. It's a way to make the component ID unique. The same
happens for a number of other IDs (e.g. property names).
This means that you have to constrain your IDs to a shorter length than
you would for the main installer. The GUID is 36 characters long so that
gives you 35 characters for the component ID.
It's the tool that generates the merge module which appends the package
GUID, so you can often turn the feature off. In WiX that is done with
the SuppressModularization attribute. However, this practice is not
generally recommended due to the name clash problem.

Subject: [WiX-users] heat.exe 9000+ Files Merge Module, warning LGHT1076
Hey all,
I was wondering if someone can help me with this issue. I'm
creating a very large merge module 9000+ files, everything looks fine
except when I try to include the MSM in wise which suggests there are
problems with directory and component tables (yes fantastic error
reporting from wise). BTW I'm unable to search the mail archive on
sourceforge so please excuse me if this topic has already been covered.
:-)
Doing a verbose output on light.exe when I create the merge
module gives me a bunch of warnings that look like.....
C:\temp\testing123.wxs(45240) : warning LGHT1076 : ICE03: String
overflow (greater than length permitted in column); Table: File, Column:
Component_, Key(s):
paneTabContainerExpandedBottom.gif_6.ECE25F21_7C22_4B3F_93EC_FA1EDBA5FB2
5
It seems to be appending the packageID to the end of the
Component key? I assume that's standard practice.
<Package Id="ece25f21-7c22-4b3f-93ec-fa1edba5fb25" Compressed="yes"
InstallerVersion="200" Manufacturer="Blah" />
This particular component looks like....
<Fragment>
<DirectoryRef Id="Img_105">
<Component Id="paneTabContainerExpandedBottom.gif_6"
Guid="d8790233-d93e-41d7-905d-2d6bd2ab855f">
<File Id="paneTabContainerExpandedBottom.gif_6"
Name="paneTabContainerExpandedBottom.gif" KeyPath="yes"
Source="c:\temp\source\Splitter\Skins\Vista\Img\paneTabContainerExpanded
Bottom.gif" />
</Component>
</DirectoryRef>
</Fragment>
I think this is the root of the problem, I'm using heat.exe
to generate the XML. Does anyone have any suggestions? Is there a limit
for the component name? How do I get heat.exe to respect a component
name size limit if there is one?
Thanks in advance
Jimbo
