Hello Wim,<br><br>As happens often, one thinks of the answer right after clicking "Send"...<br><br>In the layer's template, add a tag named [join_test], i.e. the literal text "join", an underscore, and the name of the join in the mapfile. This is the place where zero or more join templates will be inserted.<br>
In the join's template, add one or more tags named [test_joined], i.e. the name of the join, an underscore, and a fieldname.<br><br>HTH, Berend<br>
