Feature Layer Refresh not working in IE

RaviKonaparthi — Tue, 27 Jul 2010 12:15:38 GMT

Hi All,

When i update any feature the REST endpoint is updated but the featurelayer which is already present on the map is not getting updated. I tried featureLayer.refresh(), but this works fine in firefox but dosen't work in IE. Can anyone help me on some workarounds if any?

Regards,
Ravi.

I'm experiencing the same problem. Refresh on a FeatureLayer works in Firefox but not IE. Anyone know more about this problem?

Eric,

I haven't noticed this issue, is it only reproducible with a particular version of IE? Any details you can provide on how to reproduce the issue would be helpful.

Thanks
Kelly

Just a try

I had massive problems with IE recently aswell. So here just a short hint:

1. use Internet Explorer 8, latest version
2. avoid to use this tag or similar on top: <meta http-equiv="X-UA-Compatible" content="IE=7" />
3. use API version 2.1
4. if you declare dojo seperately with <script type="text/javascript" src="http://o.aolcdn.com/dojo/1.4.2/dojo/dojo.xd.js"></script>, use the appropriate version, that fits your API version see here

best luck !

I'm just running in to the same problem. I have an editing app for a feature class in Server 10. I am forcing the issue by creating or deleting features in another browser window, then calling refresh() on the feature layer in question but am not seeing an update.

It seems like the images for the layer are being cached by the browser which is then being stubborn about releasing them when I call refresh() to update them. When I zoom in or out, the updated data is reflected, but when I zoom back to the original extent, I still see the old data for a while. I'm also seeing similar things happening with Chrome. Has anyone found a workaround for these types of problems?

Is there any update on how to resolve this issue?

This works for us:

In IE go to Tools>Internet Option, and in the General Tab click the Settings button against Browsing History. Then check the 'Every time I visit the webpage' option.

I ended up finding this config - autorefresh="5" to put in the Flex API, not sure about Javascript.

how can you do this on your clients machine using JS?

anyway;
we are having this problem in IE9. Mode is MODE_SNAPSHOT. Basically refresh() reads data from cache instead of querying the service. For example Mark's solution works but there is no way to force users to select that option in their browser settings.
we added
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="Expires" CONTENT="-1">
elements in our html file. it helped solving that issue in some cases, but not always.
more oddly; same code works in one page, but wont in the another.

in order to determine the issue, we also tried removeAllLayers() and adding them again to replicate refresh() with success.

application works well on all other browsers.

UPDATE to previous message;

I had massive problems with IE recently aswell. So here just a short hint:
....
2. avoid to use this tag or similar on top: <meta http-equiv="X-UA-Compatible" content=".........." />
...

is seemed to be the solutions to this problem even without meta elements.

This worked for me:
http://forums.arcgis.com/threads/54774-Disable-Caching-on-FeatureLayer.refresh()?p=265103&viewfull=1#post265103

Modify the request with a preventCache option before it is sent to the server.
Set this up in your initialization method.

Works for ArcGIS 10.1 and IE9
Used AcrGIS JavaScript 3.3 API.

            //modify the request with a preventCache option before it is sent to the server
            // so the feature layer is not cached in the browser
            esri.setRequestPreCallback(function (ioArgs) {
                try {
                    if (ioArgs.url.indexOf("FeatureServer") > -1 &&
                    ioArgs.content.returnGeometry == true) {
                        ioArgs.preventCache = true;
                    }
                    return ioArgs;

                } catch (e) {
                    console.log(e.toString());
                    return ioArgs;
                }

Hope it heps:)

I had this problem for a very long time, but it looks that managed to find the solutions.
It is only if you use proxy page.
Just add
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
to your proxy.jsp and all the requests will not be cached.
I am using JSAPI 2.8 and server 10.0

Hope this helps

I am facing similar issue, when i add a feature on layer and call layer.refresh() it doesn't refresh the layer and show the newly added feature.Also i don't see any request fired when layer.refresh is called.

Browser: Internet Explorer 9

OS: Windows 7

JavaScript API: 3.13

Please let me know if anyone has any workarounds to resolve the issue.

Thanks in Advance.

I investigated the issue further and found that, if layer is hosted on AGOL the newly added feature is not shown on map after refreshing the layer. But it does work well when layer is sourced from ArcGIS server.

Does anyone saw the same behavior?

Re: Feature Layer Refresh not working in IE

AndrewMurdoch — Sat, 11 Dec 2021 23:00:32 GMT

I'm also seeing the same behavior with updates to Feature Layers hosted in an organizational AGOL account. When the Feature Layer applyEdits command is updated, the REST endpoint data store is updated, but the Feature Layer on the map does not immediately update its renderer (I'm changing a unique value renderer using a domain list in the attribute inspector). When I zoom in and zoom out on the map, the renderer and layer DO refresh, but I really don't want to have to refresh all the layers and tiles in the map just to change the renderer and data for a single Feature Layer...

This is all using JSAPI 3.14 (in Web App Builder Developer edition 1.2) and ESRI AGOL hosted Feature Service / Feature Layers.

Would love to know if there is a graceful work-around...

[EDIT]

Turns out the features were being updated, but I needed to call the .refresh() method on the AGOL web map Feature Layer after the deferred object from the .applyEdits method is returned. The following code worked for my particular situation (updating attributes on a custom generated FeatureLayer but displaying the graphics in the Map from an AGOL web map FeatureLayer with editing turned off):

                          var saveButton = new Button({
                              label: "Save",
                              onClick: function () {
                                 updateFeature.getLayer().applyEdits(null, [updateFeature], null).then(function(){

                                // this block is to check for "duplicate" layers that reference the same URL REST endpoint but use different symbology renderers
                                      dojo.forEach(thisWidget._operationalLayers, function (oLayer) {
                                          if (oLayer.url == webMapGLayer.url) {
                                              queryString = "$.operationalLayers[?id=$1]";
                                              var webMapLayerObject = jsonQuery(queryString, theMap.webMapResponse.itemInfo.itemData, oLayer.id);
                                              webMapLayerObject[0].layerObject.refresh();
                                          }
                                      });
                                  });                                                                                                 }
                          });
                          saveButton.startup();
