MosaicRule Error

SteveLi — Tue, 12 Apr 2011 18:25:02 GMT

I have following code to perform identify on MosaicDataSet.

var identifyParams:ImageServiceIdentifyParameters = new ImageServiceIdentifyParameters();
    identifyParams.geometry = event.mapPoint;
    identifyParams.mosaicRule = new MosaicRule();
    identifyParams.mosaicRule.where = "Name = 'WinTemp_1950_01'"

identifyTask.execute(identifyParams, new AsyncResponder(myResultFunction, myFaultFunction));

The code gives me error:

[RPC Fault faultString="Unable to complete operation." faultCode="400" faultDetail="Invalid value for parameter 'mosaicRule'"]

I believe the issue is I have to initialize all members of MosaicRule. I think this is a bug in Flex API. Can someone confirm?

Thanks.

Thanks for the reply.

Is there a workaround? what default value should I give to other members if I don't want to set them?

when is the 2.3 release?

workaround would be create key-value pairs of the parameters that you want to set, Url encode it and then pass those along as queryparameters:

e.g.:
<esri:ArcGISImageServiceLayer url="http://myserver/ArcGIS/rest/services/Test/ImageServer?mosaicRule=%0A%7B%22mosaicMethod%22%3A%22esriMosaicLockRaster%22%2C%22lockRasterIds%22%3A%5B189%5D%2C%22ascending%22%3Afalse%7D" imageFormat="jpgpng" />
