I have a custom SOE which returns a large JSON. Part of the JSON string is the extent that I will ultimately need to zoom to. The main guts of the JSON (the "results" section) takes several seconds to process and is unrelated to the "extentToZoomTo" section. Because I have rather complex symbology and am not using a cached image service, map.setExtent also takes a few seconds to complete. What I would like to do is to call map.setExtent immediately after I get the JSON, and then while the server is busy doing that, the client code can work on the "results". How can I make that happen?? What I have found is that if I simply call map.setExtent before I start processing the "results" section, it doesn't actually send that request to the server until after the results have been completely processed. I can verify that behavior by inspecting the Network tab in the developer tools. I'm guessing that this has something to do with the fact that setExtent is deferred. How can I get it to fire right away? If it matters, I have ArcGIS Server 10.2.
{
"extentToZoomTo": {
"xmin": 1234,
"ymin": 4567,
"xmax": 2345,
"ymax": 5678
},
"results": {
//A very large amount of data here that takes several seconds to process
}
}
