that makes a lot of sense Jian.  i added the following line of code to identify sampleserver6 as supporting CORS and no longer see a problem esri.config.defaults.io.corsEnabledServers.push("sampleserver6.arcgisonline.com"); i was confused initially about the CORS support in IE, but i just realized i upgraded to 10, where CORS is finally fully supported! i still don't understand why the proxy is failing for that particular server though... ...

the same error is not reproducible when you use http://servicesbeta2.esri.com/arcgis/rest/services/Utilities... strange. i tested with my own proxy (which fails in your sample app, and I couldn't reproduce the error directly from REST with sampleserver6 ... View more

are you seeing an identity manager prompt when the first call fails?  i am. i still don't understand why, but it is the calls that go through the proxy specifically that are failing.  for some reason the second request is executed as a POST (across domains, without a proxy) even in IE (which doesn't support CORS). when you don't have a census layer in the map, the request is short enough to send as a GET, so the proxy is never utilized. ...

what is it that causes your popup to be drawn halfway between the two parcels?  i tried changing the draw mode in the sample i linked above and it still allows you to select multiple polygons simultaneously. if necessary, can you please post a complete sample referencing public data? ... View more

welcome to the JavaScript forum! you're working with a featureLayer, correct?  are you calling setSelectionSymbol() somewhere in your code?  if so, the currently selected features should be redrawn with the new symbology automatically. check out this sample (and box select multiple features in the map) for a demonstration ...

you're trying to set the transparency on the entire ArcGISDynamicMapServiceLayer?  have you tried setting its opacity property instead? ... View more

is your service public?  if not, can you repro with a public service?  i have a hunch theres something wrong with the extents set for the layer but its hard to say... ... View more

the location of the resources in your webmap json don't determine whether a proxy is required.  the print request itself does.  if the url is to long to send as a GET, and the resulting POST needs to travel across domains, a proxy will probably be necessary. with regard to valid template values and output file types, the print service itself should be exposing what parameters are allowed. ...

kind of strange... i would suggest copy/pasting the query requests spawned from the application and testing them directly in the browser to try and determine whether ArcGIS Server is returning errors intermittently or whether it has a problem with some specific requests. ... View more

the printTask has the same proxy prerequisites as anything else in the JavaScript API.  (they are necessary only when POSTing across domains when either the server or browser does not support CORS). i dont think this is a very likely explanation for the selective lack of layers in your own application though.  if a proxy is needed, but not available, i would expect the entire request to fail. what happens when you modify our published print widget sample to substitute your own service, does everything print properly? ...

@adrian. these are two different bugs. ... View more

unfortunately, software defects are not "publicly" searchable.  in this particular case the bug i referenced is specific to textMarker symbols that are their own graphic (with their own geometry). i typically post bug tracking numbers here in the forum so that customers that are current on maintenance can call into support and request to be added to the list of customers affected if they are running into the same problem.  this has two benefits. 1.  it increases the visibility of bugs to our development teams 2.  afterwards the customer can track the progress of the bug using our "MySupport" portal. i am also happy to provide status updates here in the forums, but i would only take the time to reply if i come across the relevant post again and the status of the bug has changed. ...

maybe im crazy, but that sounds correct to me.... you fail to load the layer because the service isn't running (and now you're catching this error). the event handler you're talking about would fire either if 1. the layer is loaded successfully. 2. the layer loads and then a problem is encountered. ...

there is more than one technique you could use to improve performance.  check out the following article on featureLayer/graphicLayer performance for a more in depth discussion. here are a couple things to try: 1.  perhaps you could set the minScale property on the map graphics layer so that the features only draw when you're zoomed in closer? 2.  if you are working with a featureLayer from an ArcGIS Server map service, you could display the data in a dynamicMapServiceLayer instead and work with the featureLayer class in selection mode instead to query for individual geometries and attributes on the click of the map. (see sample of this in action) ... View more

we were able to reproduce problems directly in REST.  it appears that print services do not currently honor the size of textSymbol supplied in webMap JSON.  here is the tracking information. [NIM090748: Printing service fails to honour the font size of textSymbols.] ... View more
