We're using Stream Layers, and I know you're not meant to use them, but people don't listen and keep trying to use bad naming conventions, so I was looking for a workaround, which I don't think exists. Thanks

Good Day Would it be possible to use compression with the Stream Layer web socket? If so, how do you enable it, if not, why? Thanks

Good Day Is it possible to run a feature effect query using special characters in the field name? Could I run: const query = { where "good(%) = '100'" } I know using arcade, you can do "When($feature['good(%)'] = '100')", but when I try that with non-arcade queries it doesn't work. Is there a way to pull this off? Thanks

Good Day I have a Stream Layer that works, is there a way to add a Bearer token in the header of the Web Socket when the Stream Layer connects, if so, how? Here is my current Stream Layer object: const websocket = 'ws://blah' return new StreamLayer({ fields: metaLayer ? this._metaFields : fields, geometryType: geometry, id: streamLayerId, labelingInfo: [layerLabelClass], maxReconnectionAttempts: 100, maxReconnectionInterval: 10, objectIdField: 'objectId', renderer: renderSetting, timeInfo: { trackIdField: "assetSectionId" }, webSocketUrl: `${websocket}`, updateInterval: 100 }) Thanks

Good Day I can't use the layerView query because there is no guarantee the layerView is zoomed out so the extent captures the entire map. What I opt'd to do instead is record the ID of all features that I excluded. When I'm going to select them, by adding a graphic highlight, check the list, and if the matching index of the ID is -1, I know it's not excluded. I think it's the best workaround. Is there any way to query a layerView so it considers the entire map? I know you can pass a geometry, could I use that to override the visible area, and return everything? Using the layerView would be very helpful, but I don't think it will work for my use case because I don't know what the user is looking at. Thanks

Good Day I have a situation where I need to hide several features in the Stream Layer, but I can't set a definitionExpression, so I'm setting the layer's featureEffect: const featureFilter = new FeatureFilter({ where: featureQuery }); layer.layer.featureEffect = new FeatureEffect({ filter: featureFilter, excludedEffect: "opacity(0%)" }); This works, and the features “disappear”. The issue I have, they still respond to the “hitTest”, so if I have a sketchWidget active and do something like: this.sketchWidgetPointerUpEvent = this._view.on("pointer-up", (event) => { this._view.hitTest(event).then(async (response) => { if (response.results.length && this.lassoSet) { this.lassoSet = false; this._view.graphics.removeAll(); const geometries = response.results.map((graphic, index: number) => { if (graphic.graphic.geometry) { return graphic.graphic.geometry } }); const queryGeometry = await geometryEngineAsync.union(geometries); this.selectFeatures(queryGeometry); } }); }); My question is, how do I stop the excluded features from being selectable? Is there a better way to query the features, and I don't think using the layerView.queryFeatures would work because that would only consider what's in the active view, not what is outside the view? Is there a way to look at the effect of the feature? If I do use layerView.queryFeatures, could I force it to look at the entire map instead of the view (I don't think so). Thanks for any help provided. Thanks

That's precisely what I'm trying to do! Thanks for the help

Good Afternoon I think I finally found the issue! To make sure I run the progress spinner until features are on the map, I'm using an interval to carry out the following steps (generalized): 1. Wait for the Layer View 2. Build a query to find features in the Layer View 3. Run "queryFeatures" 4. If the feature count returned is >= 1, then stop the spinner. The issue is if my view extent doesn't contain any features it won't get updated, because if I zoom out they pop in. if I have the following code: const query = { geometry: this._view.extent.clone().expand(100), outFields: ['*'], where: '1=1' } layerView.queryFeatures(query).then((features) => { if (features.features.length) { clearInterval(waitForFeatures) this.layerLoadedEvent.emit(true); } }) How can I check the entire map? Thanks

So the output I posted is returned to the StreamLayer from the Web Socket, and all the other layers have the same structure, so I'm perplexed. The render setting seems fine, the geometry seems fine, the attributes, and fields seem valid, so do you know if there's away to get better logging information from the StreamLayer? When I look at Load Warnings or Load Errors, I have none, which would tell me the data was / is fine because I don't know what else to take from that. I would suspect something must provide me debugging information as the features are loaded from the Web Socket into the StreamLayer. Thanks

Good Day I'm confused about this issue, I have a websocket that is returning data to me. ex: { features:[{ "geometry": { "x": -8841036.030462436, "y": 5471327.551341704 }, "attributes": { "objectId": 31311, "assetTypeId": 14, "assetSectionId": 31311, "assetId": "ST3472", "name": "Silly Face Circle", "gisId": "ST11111", "assetStatus": "In-service", "installationYear": 2010, "replacementCost": 8800, "replacementCostYear": 2021, "costAdjustmentFactor": 1, "fixedCost": 0, "exclude": "No", "material": "Something", "count": 1, "owner": "Me", "condition": 86.3, "sl": "80.00", "rsl": "69.00", "decisionClass": "Something Something", "degradationClass": "Something Something", "performanceClass": "blah - face, "criticality": 50, "risk": 6 } }], type: "features" } I have the fields setup as: [ { "name": "objectId", "alias": "objectId", "type": "oid" }, { "name": "assetTypeId", "alias": "assetTypeId", "type": "double" }, { "name": "assetSectionId", "alias": "assetSectionId", "type": "double" }, { "name": "assetId", "alias": "assetId", "type": "string" }, { "name": "gisId", "alias": "gisId", "type": "string" }, { "name": "name", "alias": "name", "type": "string" }, { "name": "assetStatus", "alias": "assetStatus", "type": "string" }, { "name": "installationYear", "alias": "installationYear", "type": "double" }, { "name": "length", "alias": "length", "type": "double" }, { "name": "area", "alias": "area", "type": "double" }, { "name": "volume", "alias": "volume", "type": "double" }, { "name": "quantity", "alias": "quantity", "type": "double" }, { "name": "replacementCost", "alias": "replacementCost", "type": "double" }, { "name": "replacementCostYear", "alias": "replacementCostYear", "type": "double" }, { "name": "costAdjustmentFactor", "alias": "costAdjustmentFactor", "type": "double" }, { "name": "fixedCost", "alias": "fixedCost", "type": "double" }, { "name": "exclude", "alias": "exclude", "type": "string" }, { "name": "zone", "alias": "zone", "type": "string" }, { "name": "diameter", "alias": "diameter", "type": "double" }, { "name": "depth", "alias": "depth", "type": "double" }, { "name": "rimElevation", "alias": "rimElevation", "type": "double" }, { "name": "coverDiameter", "alias": "coverDiameter", "type": "double" }, { "name": "numberofPipesIn", "alias": "numberofPipesIn", "type": "double" }, { "name": "numberofPipesOut", "alias": "numberofPipesOut", "type": "double" }, { "name": "soilType", "alias": "soilType", "type": "string" }, { "name": "soilCondition", "alias": "soilCondition", "type": "string" }, { "name": "classification", "alias": "classification", "type": "string" }, { "name": "material", "alias": "material", "type": "string" }, { "name": "roadsideEnvironment", "alias": "roadsideEnvironment", "type": "string" }, { "name": "functionalClass", "alias": "functionalClass", "type": "string" }, { "name": "coverType", "alias": "coverType", "type": "string" }, { "name": "serviceType", "alias": "serviceType", "type": "string" }, { "name": "overflowWeir", "alias": "overflowWeir", "type": "string" }, { "name": "risk", "alias": "risk", "type": "double" }, { "name": "criticality", "alias": "criticality", "type": "double" }, { "name": "performanceClass", "alias": "performanceClass", "type": "string" }, { "name": "decisionClass", "alias": "decisionClass", "type": "string" }, { "name": "initialCost", "alias": "initialCost", "type": "double" }, { "name": "defectFlag", "alias": "defectFlag", "type": "string" }, { "name": "count", "alias": "count", "type": "double" }, { "name": "owner", "alias": "owner", "type": "string" }, { "name": "showOnCapitalPlan", "alias": "showOnCapitalPlan", "type": "string" }, { "name": "groupIDCorridorID", "alias": "groupIDCorridorID", "type": "string" }, { "name": "degradationClass", "alias": "degradationClass", "type": "string" }, { "name": "formulaGroup", "alias": "formulaGroup", "type": "string" }, { "name": "condition", "alias": "condition", "type": "double" }, { "name": "sl", "alias": "sl", "type": "double" }, { "name": "rsl", "alias": "rsl", "type": "double" } ] The StreamLayer object is: return new StreamLayer({ fields: fields, geometryType: geometry, id: streamLayerId, maxReconnectionAttempts: 500, maxReconnectionInterval: 500, objectIdField: 'objectId', renderer: renderSetting, timeInfo: { trackIdField: "assetSectionId" }, webSocketUrl: `${webSocketAPI}api/MapStream/stream` }) Which is how I'm creating 20+ other layers that show up correctly. This one layer won't show up, doesn't list any features, and it should have ~3000, BUT, doesn't list any errors, or warnings, and will return it's "Loaded". Is there any way to get additional information? I'm assuming something in the data is bad, but shouldn't that generate a warning or error? in loadWarings / loadErrors? Thanks for any help Cheers

‎02-14-2025

Possible, it stopped complaining about the % sign when I did that, fields that don't have % sign are rendering properly, but I can't get %blah to show up correctly.

‎02-14-2025

Good Day I have a field that starts with a % sign %blah, inside a value expression can I use that value escaped? Something like: When($feature.%blah <= 0) If I leave the % sign, I get an error, and I can't find any information on escaping the % sign, is it possible? Thanks

Figured out the issue, apparently the "TRACKID" has to be unique between feature additions, which I was unaware of. I thought it worked like an Object ID, but it doesn't. After randomizing the Track ID, now it's fine. That should be added into the documentation 🙂

‎12-11-2024

Good Day I'm having a new issue, when I change the extent of the view, such as zoom in / out. I first want to clear all the existing features from the layers, then grab the new features. Assuming I have a polygon of the extent, if I call: layers.forEach((layerObject) => { const layer = layerObject.layer; layer.sendMessageToClient({ type: "clear" }) }) Before doing: layers.forEach((layer) => { if (layer.layer) { layer.layer.sendMessageToSocket({ asset: layer.assetTypeId, boundingPolygon }) } }) The question is: How do I wait until the clear is complete, before trying to grab the features? If I can do that, then the load on the map will be greatly reduced. Thanks
