nevermind - i see it updated in your codepen sample. Thank you!

That sounds good - just explicitly verifying - does that mean we will be able to use our current servers with 4.20 even if they are not yet updated? Also - does 4.next of the api include bug fixes or do i have to wait for the release to try it out?

Thank you for looking into this. So you're saying it's both an issue with the version of our server, but also for the REST api?

I am exploring the use of lerc and client side handling of pixel data. In the specs I see it as capable, however I'm not sure how to configure my layers to get it to work. One is a classified one like landcover (just doesn't show), the other based on floating point values (gives an infinity error). Is this a bug, our service, or user error on configuring the layer?

I am trying to explore the idea of hosting our own version of the minimalist app, to support adding page surrounds etc, extra features. I have noticed that my developer version of AGOL has the modern updates (ie express setup), but a lot of the documentation around configurable apps is for the old version. Regardless of all this, in the dev AGOL how might I get my self-hosted minimalist template working and configurable? It will open for configuration, but the express selections for a map don't do anything, and also switching to full doesn't have an effect. I have tried pasting various examples into the Configuration Parameters section (old and maybe new?), and nothing seems to make a difference. Clearly I should be pasting something, but I'm not sure what.

Oh that's great thank you! Sometimes you just need to know what to search for. It seems like that would have been an obvious result of my searching, but it wasn't.

I have an application that is requesting a computeStatisticsHistograms from our image service based on a user's feature selection. The features vary in size. I have noticed that I get this error returned for geometries over a certain size. On layers that have higher resolution, that threshold is lower (only tolerates smaller geometries). Clearly from the error, there is a size limit, but I can't find what it relates to. Using ArcGIS Server 10.4 but I also tried on an ArcGIS Online layer at 10.71. error retured: "code": 400,
"message": "Invalid or missing input parameters.",
"details": [
"The requested image exceeds the size limit."
] Has anyone come across this? What can we do to tweak the services to prevent this error from happening? Alternatively, if I knew what the limit was in relation to some math - ie.. no more than N pixels - I could trap it.

I have seen in the API documentation a reference to SearchResultRenderer class. SearchResultRenderer | ArcGIS API for JavaScript 4.15 In addition, I have seen examples where after a search, popup displays "more results". I'd like to display that "more results" menu separately from a popup. Preferably as a list of results before the user pics one. I have not seen an example where this is done - I'm wondering if anyone has an example I could look at - or if you know how I might leverage that class/something else to create a list in a new location. I know how to do this: searchWidget.on("search-complete", function(event){
// The results are stored in the event Object[]
console.log("Results of the search: ", event);
}); I'm looking for a better way - I'm wondering if SearchResutRenderer might be it or something else.

I went looking in the LayerList widget's source code for clues, and figured it out. I was using the same name for my trigger function as the method for raising the trigger. So changing _triggerAction to _myTriggerAction resolved the issue. Leaving it here for anyone else.

Hi, I'm trying to extent the LayerList widget as a means to reuse preferred settings/code between projects. The trouble I'm having is in implementing the trigger-action handler. I have ported the code from the sample. It worked fine outside of my widget extension, so It's likely a matter of scope, but I can't figure out how to change it. I'm writing my widget in TypeScript. In postInitialize, I'm setting up the list item actions, and they seem to work. But on click, the event coming through to _triggerAction doesn't have event.item. I noticed it is of type "click". Might be a clue as to what is going on?? relevant bits: postInitialize() {
var defineActions = this._defineActions.bind(this);
this.listItemCreatedFunction = defineActions;
var triggerAction = this._triggerAction.bind(this)
this.on("trigger-action", triggerAction);
}
private _triggerAction(event) {
var layer = event.item.layer;
var id = event.action.id;
if (layer) {
switch (id) {
case "full-extent":
this.view.goTo(layer.fullExtent);
break;
case "information":
window.open(layer.url);
break;
case "increase-opacity":
if (layer.opacity < 1) {
layer.opacity += 0.25;
}
break;
case "decrease-opacity":
if (layer.opacity > 0) {
layer.opacity -= 0.25;
}
}
}
} I'm using JS API 4.11. Ideas? Liz

I resolved this one on my own, though ESRI did also provide a solution. Both here. Revised codepen: https://codepen.io/lizeidsness/pen/zgOpBL My problem was the watch wasn't set on the right thing. So there's an initial watch on the activeLayerInfos.length property. If there's a legend it will be > 0. New: If there's a layer in the legend, set a watch on it's legendElements object. If this changes, it will update accordingly. watchUtils.when(legend, "activeLayerInfos.length", setWatch);
function updateLegend(layer) {
var activeLayer = legend.activeLayerInfos.find(e => {
return e.layer.title == layer.title;
});
if (activeLayer.legendElements.length < 1) {
return false;
}
var element = activeLayer.legendElements.find(e => {
return e.type == "symbol-table"; //add additional support
});
element.infos.forEach(e => {
lookup.forEach(item => {
if (e.label == item[0]) {
e.label = item[1];
}
});
});
}
function setWatch() {
if (legend.activeLayerInfos.length > 0) {
legend.activeLayerInfos.forEach(al => {
watchUtils.when(al, "legendElements", function () {
updateLegend(al);
});
});
}
} ESRI's solution would intercept the legend response from the service. It would work well enough, if there isn't an appropriate API property to watch instead (in this case) esriConfig.request.interceptors.push({
urls: imageryLayerUrl + "/legend",
after: function (response) {
response.data.layers[0].legend.forEach(l => {
l.label = "not " + l.label;
});
}
});

Glad I could help! It will always be hard to keep things on top of the map without covering something. It's also depends on the browser size, or container if this will be in an iframe. Have fun!

It is your lucky day - I needed a break from what I was doing, and I learned some things along the way. If you use this version (combination of the esri sample and your code), you'll notice there's a console.log output of the passport office name on map click. Line 205. You can handle the rest I think. A couple problems with your original. I disabled popups on fLayer. Consolidated the event handling because you have 3 views. Complicated! Also created a click handler!

There's a couple things going on. Popups need to be disabled on view/layer, or manually handled. Also FeatureLayer doesn't have a click event. This sample might help: https://developers.arcgis.com/javascript/latest/sample-code/view-hittest/index.html In this sample, the view events are handled manually. It has a lot more going on, but hopefully the event flow can help. In codepen, after line 139 - I added window.open("http://google.ca"); and on feature click (not mouse over) it opens a window to google.
