I have developed a custom extension and have found that if I use
newline/return character xml codes in text fields, WiX incorrectly generates
the temporary IDT files. Thus when WiX is trying to apply the IDT files to
the MSI, it fails. For example, suppose I have the following custom table:
<CustomTable Id="MyCustomTable">
<Column Id="Info" Type="string" Width="0" Localizable="yes"
Description="..." />
<Row>
<Data Column="Info">First line

Second line</Data>
</Row>
</CustomTable>
WiX generates the correct IDT file which looks like:
http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/file/n5214598/Custom_Table.png
Notice the characters codes where the new line and return characters are at.
If I try and use my custom extension, WiX doesn't add these character codes
to the IDT file. It actually keeps the new lines and spaces. At first I
thought maybe my extension was acting up but I tested this use the WiX
Firewall extension with something like:
<File Source="C:\Program Files\Windows Installer XML v3.5\bin\candle.exe">
<f:FirewallException Scope="any" Id="Hello_There" Name='hello


 ther' />
</File>
The error you get in Visual Studio is:
Error 12 There was an error importing table '<table>' from file
'C:\Users\jnewton\AppData\Local\Temp\vzpbgirf\<table>.idt'.
C:\Users\jnewton\AppData\Local\Temp\vzpbgirf\<table>.idt 1 1
Is there a workaround to this? Maybe I am doing something wrong but you can
use those xml codes in other WiX tables and they work great.
