FME Import Zoom to Smallworld Map

In the SWAF version of the Smallworld-FME plugin, it would be nice to have the current Smallworld map "goto" the bounds after the FME import has completed. This comes in handy when you want to easily find your just-imported data for subsequent review.

Apparently this functionality used to exist in the pre-SWAF version of the FME plugin.

I have uploaded a sample of some tweaks you can make that will enable this functionality at Smallworld version 4.x (SWAF).

The basic steps are:
  1. in fme_tics_client.private_run(), determine if there are any smallworld_product.applications that might be interested in knowing where the FME-imported geometry bounding box is
  2. if there are any such applications, then create a dynamic variable geometry_set that!received_feature() can add newly-created geometries to
  3. back in fme_tics_client.private_run(), send a :goto_request databus message to all the relevant applications with the geometry_set populated in!received_feature()

Have a look at this file (fme_goto_import_geometry_set.magik) to see the details of how it is done.
