[mapserver-users] Multiline string error

[Ian Walberg]

Jukka/Steve,

How do I add a text label to the feature in this case?

Removing the label from my problem layer stops the error occurring.

Thanks

Ian

Hi,

This was fun, I had never tried anything like this before.

Works for me on Windows with a week old Mapserver build from gisinternals. Big thanks for Tamas for the builds by the way.
