ID 126090 - Args files: 'scenegraphLocationArray' widget type doesn't allow creation of new elements

Assigning the 'scenegraphLocationArray' widget location type to a parameter in an .args file for a renderer procedural results in the correct widget to be displayed, but new elements cannot be added using the 'Add Locations' button.

Workaround

The sortableArray widget behaves correctly and can be hinted to display its array elements as scenegraphLocation widgets. This is ok but doesn't have the top-level add-from-selection, etc.

  <string name='workaround' default='/root/taco' forceArray='True' widget='sortableArray'>   <hintdict name="childHints">    <string name='widget' value='scenegraphLocation'/>   </hintdict>  </string>
