[mapguide-users] text labels sometimes null when using concat and line breaks in studio

[VOLZ Mark (FN)]

Concat only seems to work "as expected" when you only do 2
fields/strings at a time but you can nest them.

To do the below try this;
Concat (   COLUMN_A  , concat('\P', COLUMN_B ))

Hello,

I'm building text labels on top of feature sources with this expression:

 Concat (   COLUMN_A  , '\P', COLUMN_B )

It is giving me the line break that i want between the two fields but
about 25% of my polygons are missing the label. When i select the layer
in the AJAX viewer I see all the data there. Any idea why it would
disappear?
