Select features within selected polygon(s) not working

RyanSellman — Mon, 29 Sep 2014 14:31:28 GMT

I am working on a sample that performs an attribute query on one layer and uses the results as geometry for a second query, which does a spatial intersect on another layer. The first query works just fine but the second does not. I get no errors in the console and when looking at the network traffic, the second query doesn't appear to be firing. Can someone take a look at this and help? Thanks in advance!!

Here's the fiddle!

Ryan,

Feature 0 of the first queries FeatureSet does not seem to have an intersecting point in your second query. If I change it to twpQueryGraphic = featureSet.features[5]; then I do get a point in the second query.

Ryan,

Here is your sample with the results of the first query being unioned before the second query is executed. You may want to add some indication to the user that the union operation is occurring.

Robert,

Thanks so much for the response. With your adjustments, the sample seems to be working like I want it to.

I appreciate your help!!
