Hello,
Does anyone know the solution to this? I have a similar problem with setting
the property through a CustomAction. I understand Sunghwa was getting the
"action" error because "Id" was not defined. I no longer get the error but
the property is not being populated. This is what I have
<CustomAction Id="SetSQLServer" Property="SQLSERVER"
Value="[ComputerName]"/>
<Property Id='SQLSERVER'>
<RegistrySearch Id='RepositoryLocation'
Key='SOFTWARE\MyCompany\MyProduct\MyVersion\MyComponent'
Name='RepositoryServer'
Root='HKLM'
Type='raw'
/>
</Property>
<InstallExecuteSequence>
<Custom Action='SetSQLServer' Before='InstallInitialize' />
</InstallExecuteSequence>
SQLSERVER is always empty. I would like SQLSERVER to default to the
ComputerName if the reg key doesn't exist. It seems like the SetSQLServer
action is not being called but I am not sure. Any ideas on how to fix this
or debug it would be appreciated.

Subject: Referencing other property as default value of a property?
Hi all,
I am trying to set a property called SQLSERVER like below. What I am trying
to
do is that I take registry value as its value if exist. If it doesn't exist,
I
should take computername as default value. And user should be able to
override
this value by specifying it in msiexec.exe's command line.
<Property Id='SQLSERVER' Value='[ComputerName]'>
<RegistrySearch Id='RepositoryLocation'
Key='SOFTWARE\MyCompany\MyProduct\MyVersion\MyComponent'
Name='RepositoryServer'
Root='HKLM'
Type='raw'
/>
When I build this, I get exception like below:
Myserver.wxs(50) : warning CNDL1077 : The 'SQLSERVER' Property contains
'[ComputerName]' in its value which is an illegal reference to another
property. If this value is a string literal, not a property reference,
please
ignore this warning. To set a property with the value of another property,
use
a CustomAction with Property and Value attributes.
I am trying to figure out I can do this by using CustomAction, but adding
below
generates another compilation error:
<CustomAction Property='SQLSERVER' Value='[COMPUTERNAME]'/>
candle.exe : error CNDL0001 : Cannot set column 'Action' with a null value
because this is a required field.
Can someone kindly teach me how I can solve this?
Thanks,
Sunghwa
