<br>
However, if I have styling in the source layers (i.e. layer_1_for_union and layer_2_for_union) and use STYLEITEM "AUTO" in the union layer, the two source layers must have STATUS DEFAULT for anything to show up (which, I think, causes them to be drawn twice?).<br>
<br>
Am I missing something with how UNIONs and STYLEITEM "AUTO" work? Or is this how it was designed?<br>
<br></blockquote><div><br>Christy,<br><br>The UNION layer should show the features from the source layers regardless of their STATUS setting, so all of the features from the sources should be rendered by default. A new attribute (Union:SourceLayerVisible) has been added to the union layer so you can set up a FILTER expression to display the features from only the "visible" sources if required. The most common setting is to disable the visibility of the source layers (by setting the STATUS of the layers or classes to 'off') to avoid the feature duplication.<br>
