Weird query done by DetailsTask

Ganael_Jatteau — Wed, 01 Sep 2010 15:24:00 GMT

Hello,

I use a DetailsTask to explore a rest layer on a arcgis 10 workgroup. Sometimes, the http request done by this task looks like:

http://localhost:8080/query?outFields=&f=json&returnGeometry=false&where=null%20is%20not%20null&spatialRel=esriSpatialRelIntersects"]. URL: http://localhost:8080/query?outFields=&f=json&returnGeometry=false&where=null%20is%20not%20null&spatialRel=esriSpatialRelIntersects

And of course it returns an error.

The code is quite simple:

var detailsTask:DetailsTask = new DetailsTask();
detailsTask.url = "http://ags10wg:8399/arcgis/rest/services/test1/MapServer";
detailsTask.getDetails(7, new AsyncResponder(detailResult, onFault));

Anybody else got this problem?

It seems that this problem happens when the layer names have some aliases. I've downloaded the latest flex lib 2.0 from the resource center and the problem still happens.

the method:

detailsTask.getDetails(layerId, new AsyncResponder(detailResult, onFault));

first queries the JSON of the layer. Then there must be a bug interpreting the json because the next query done to the server is the one described in the previous post.

bug in DetailsTask

I confirm. DetailsTask doesn't work when the layer names are different from the datasources in a service.

Can you share the code in your detailResult function?

I'm not able to reproduce this issue using the code below. Can you modify the code below to show how this issue can be reproduced?
