Take a look at this thread I started a couple weeks ago. ESRI might have introduced a bug within the MapImage functionality with v3.3 of the API. Look at Derek's initial response to my question. There's a certain way you'll need add the mapImage layer to your map (basically, after the map loads- not during).

This bug looks to have been logged as NIM079257 but there is no status or evaluation attached to its description. I'm experiencing this issue both with KML files and mapImage Layers. I'm assuming this has no fix or workaround still? My example: http://gismaps.snoco.org/fws/ Under the "Show Me.." menu, Storm Total Precipitation is a KML Layer and Radar Image / 1-Hour Precipitation are mapImage Layers. Click to turn the layer on and zoom the map out three levels to see the effect. Unlike the original poster, I'm using ArcGIS Server 10.1 and v3.3 of the API.

@Diana- Do you have a screenshot of what that looks like that you could share? I'm in the same boat and the code provided earlier in this thread didn't work well for me and my own kludgy code to "sense" where my feature is on the map and adjust accordingly is almost more trouble than it's worth. I did submit an enhancement idea for ESRI to add an option to map creation so that the API takes care of all this. It's ESRI's code and they know it better than any one of us. Vote if you're so inclined.

Welcome to the hell that is Internet Explorer. You can look forward to more of this kind of maddening behavior if you ever try using the charting capabilities of dojo. To your follow up question, you can try reading this: Specifying legacy document modes

I can't explain WHY this happens but Jeff's question about window.setInterval() to refresh my page every 5 minutes appears to be on the money. What I ended up doing was calling my update function immediately before specifying the window.setInterval() command and now the features display immediately like they did under v2.8 of the API. One frustrating gremlin down, several more to go. Thanks again to everyone and especially Jeff! Cheers- Steve

Yeah, I noticed that it happens to any of these NWS mapImage overlays. I just wish I knew how to correct it!

Ok, for comparison, here's a version of our app using v2.8 of the API: http://gismaps.snoco.org/fws28/ This loads quickly and my data (the square symbology) shows up immediately. It's the same code base with respect to the page's 5 minute refresh and the dojo charting, just modifed as required to get running under v3.3.

If you can get the featureSet of your layer, you could sort the featureSet since it really just is an array: var _sort = function(field) { return function(a, b) { var x, y; x = a.attributes[field]; y = b.attributes[field]; return (x < y) ? -1 : 1; }; }; theFeatureSet.sort(_sort('Your Field Name')); Another way of sorting the featureSet would be: theFeatureSet.sort(function(a,b) { return a.attributes.fieldName - b.attributes.fieldName; }); Both of my examples would be for a numeric field.

I can tell you that neither of these things were issues with this under v2.8 of the API. I'll try to produce a version using the 2.8 API for comparison.

Here is the live link for the "drifting" overlay I was previously describing: http://gismaps.snoco.org/fws/ Load the page. Under the "Show Me' dropdown, click the checkbox for Radar Image. Now zoom out one level. Note where the radar returns are. Zoom out again one level. Watch the radar returns drift back eastward. Zoom out one more level. This represents the true spatial position of the overlay.

Ok, we finally have a live version of our app for you to see the lag that I've been describing: http://gismaps.snoco.org/fws/

Thanks, Derek. That did the trick and now the image displays. I feel somewhat special having stumbled across a bug 🙂 One issue I'm having as I try and incorporate this back into a more complex app I'm developing. From a certain LOD out, the image is displayed in its correct location. From that certain LOD inward, however, the image begins to shift westward and continues to shift further westward with each successive zoom in. If I reverse course and zoom back out, the image will get closer and closer back to where it is supposed to be. I hope to have a live public version I can link to within 2 weeks but for now here are a couple screenshots which show the problem. "ZoomLevel01" shows the mapImageLayer in its correct spatial location. After I zoom my map in one level, I get "zoomLevel02." As you can see, the image has now shifted westward. I'm stumped as to what may cause this because my app uses the same basemap and initial extent as what I originally posted in the simple example (and what's used in your fiddle). Thoughts, guesses?

I want to add some weather service radar overlays to my app. Originally, I was hoping to add them via a KML/KMZ as provided by this NWS site. After reading the API documentation about KMLLayers, i concluded that this type of KML layer might not be supported (image overlay). That led me to the MapImage layer and I'm having no luck getting the image to display. While investigating the guts of the NWS KML file, I see that it's simply a georeferenced GIF file: [ATTACH=CONFIG]21185[/ATTACH] I noted the lat/long extents, along with the image dimensions and have tried implementing a simple example with no success. So what am I missing?? THANKS!

Hi Ken, No- this lag occurs at the initial page load. I can still pan/zoom and interact with my other layers; it's just that this one featureLayer won't appear for 4 minutes. After it finally does appear, everything functions normally.

‎01-29-2013

As an update, my own stripped down test app does not exhibit the lag time behavior I originally described. Looks like I'll need to provide a link to the actual app. I'll do so ASAP, but that probably will be in 2 weeks.

My Ideas
