I'm having trouble setting an output parameter of type "Feature Set" in a python toolbox. Here's what I have currently:
The first output parameter displays as "empty"; if I print paramers[0].value it will output "None" ..
The second TEXT parameter seems to work fine; I get the following output:
{"displayFieldName":"","fieldAliases":{"OID":"OID","Attribute1":"Attribute1"},"geometryType":"esriGeometryPoint","spatialReference":{"wkid":4326,"latestWkid":4326},"fields":[{"name":"OID","type":"esriFieldTypeOID","alias":"OID"},{"name":"Attribute1","type":"esriFieldTypeString","alias":"Attribute1"}],"features":[{"attributes":{"OID":1,"Attribute1":"point at 1, 1"},"geometry":{"x":1.0000000000000568,"y":1.0000000000000568}},{"attributes":{"OID":2,"Attribute1":"point at 2, 2"},"geometry":{"x":2.0000000000000568,"y":2.0000000000000568}}]}
Anyone know why this doesn't work?
Thanks in advance :)
