Description

I've tried creating an ApplicationDefinition? (Slate) out of one of our existing cemetery maps to see what it looked. When I loaded the map, it gave me this error

Fusion Error: Missing } in property list at /fusion/mapguide/MapGuide.js (line 193)

So I looked at that particular line in firebug, and it was a json object being eval'ed, so I reloaded the map again so I could trap the json output, and this is what I got from firebug (copy/pasted)

The short answer is:

  • At least one of the layers was broken because it was linked to a database that didn't exist on our test machine. The old AJAX viewer would've gracefully handled it by simply not rendering that particular layer.
  • The json output above is missing two } characters 1 - At the end of the error property of the json object 2 - At the end of the json object.

Could the MapGuide stack trace be interfering with the JSON output?

Paul, Should MGOS format the response in a certain way? Tom

Resolution: fixed
Status: newclosed

Doesn't happen now in RC4, using same dataset with same broken layer.
