<esri:Geoprocessor  executeComplete="gp_jobCompleteHandler(event)"  useAMF="false"  showBusyCursor="true"     id="gp"        url="http://yanli/arcgis/rest/services/gp1/GPServer/polygon"/>

</fx:Declarations>
gp.execute(param);  //  error  here!!!

when i chang the code with setting "URL" null ??the error is same .... but the param have the value,the GP server run well in the ArcMAP

gp.execute(param);  //  error  here!!!

I am carazing !!!!!!!!!!!!!!!now

the error message as following:

What version of the API are you using?

What is your param?

Can you share a complete test?

Try setting "returnGeometry" to true on your Query.

See:

Other troubleshooting steps would be to test your GP service using its REST page. If the service gives you the expected results back, it should work in your flex code. Other things to check would be what gets sent in the http request. You can use firebug here to help. Copy the FeatureSet JSON representation and then test it using your REST page. Also make sure your GP service is synchronous, as I see you are using execute vs submitJob.
