This is an old idea, but I have recently come across this restriction myself when attempting to create a relationship class in order to publish a feature layer and related tables to ArcGIS Online. It seems the only way to create a related table in ArcGIS Online is currently to create a relationship class prior to publishing. It should NOT require a Standard/Editor license to create a relationship class in a file geodatabase! As Ray states, this is basic functionality of the geodatabase, so we should be able to do this with a Basic/Viewer license. Currently, a customer of ours will need to upgrade at great cost, just to get related tables to work in ArcGIS Online, which is ridiculous. ... View more

Our issues didn't result from using append. We are sending requests directly to the REST endpoint via python (as the code was developed prior to the ArcGIS Python API) and getting the 504 gateway timeout errors. Any methods you are using via the ArcGIS Python API will ultimately result in a http request to the REST endpoint of the service using applyEdits, updateFeatures, addFeatures, or deleteFeatures operations, which are exactly the same operations we are using directly via python. Also, setting any timout options on the client-side requests makes no difference, since these cover the client-side timeouts only and the error (504 gateway timeout) comes from an internal timeout on the server-side. Within our code, we are capturing the http error and re-sending the same request again multiple times. In most cases this works, but occassionally we still get failures after multiple attempts. These don't result in crashes as we just log the error and continue. ... View more

Hi Kelly, The requests are to a hosted feature service in ArcGIS Online, via the REST API, through python using urllib/urllib2. The requests are either addFeatures, updateFeatures or deleteFeatures and we have a setting that limits the number of features per request (currently set to 2000). At the moment the script is run every 15 minutes and the work-arounds we have in terms of repeating requests are generally working. Recently we have not seen too many failures and any failed updates generally succeed in a subsequent run of the script. It would still be interesting to know what the cause is. I suspect something internal to the platform is timing out when the request contains a large number of adds/updates or when there is heavy load at peak times. Though I've no conculsive evidence to support this or have much time to see if there are any patterns. John ... View more

I've just begun experimenting with Operations Dashboard for a potential customer. Based on this here are some suggestions for the app - there may already be solutions for some of these, but I've not found them yet: Allow an option to add a % symbol in the number format without multiplying the value by 100. For example, my value is 5 not 0.5 and I want to show this as 5%, not 500%. Search does not appear to work the same as other apps. It should be possible to configure search settings in the app (as per Web App Builder) to add layer search, choose geocode services and limit geographic region for the world geocode service as well as specify search order. Currently I can't even get the layer search to work in OD when this is configured in the web map and working in map viewer. Add a 'Select' action to the List element. Currently it's possible to Filter, but my customer wants to select (and highlight) the feature and see it in context with other features. Currently, the Select tool on the map and the the List element with filter action allows the user to select features on the map and narrow down the selection to a single feature in the List element, but this filters out all other features on the map and is not intuative as it prevents further selections on the map until the List item is clicked again to remove the filter. On pie charts, allow for showing a single value as the percentage. For example, I have a single value that represents a percentage (e.g. percentage resolved = 75), but when I display as a pie chart this just displays as a whole, not as 75% with the remainder as 25%. Make attribute/field values available in all the dashboard elements using the {fieldname} syntax. Currently this is supported in some parts of some elements, but not in others. It would be useful if the user we able to filter the map based on dates. For example, the operational layer includes data from multiple years, but the user is primarily interested in the current year. The layer could be filtered initially on the current year (i.e. between two dates) and the user has the option to change the date filter. It would be good to limit display of data in the various elements only to the selected feature(s) on the map. Currently, where no features are selected on the map, the charts, indicators etc show data from the first feature in the layer (when maximum features limited to 1). If there are solutions or work-arounds for any of these, I'd be glad to hear them. John ... View more

Having the same problem. I want to add a % symbol to the label, but when I do this, it multiplies by 100, so instead of 5%, I get 500%. The HTML code doesn't work and there appears to be no way to escape the % to prevent it from multiplying. This needs fixing - we shouldn't have to change our data to fit the restrictions of the app. ... View more

I've just begun experimenting with operations dashboard and can't beleive there is no option to change the selection color, or why the default color isn't cyan like in all the other Esri applications. This is almost certainly the end customer is going to ask to change, so definitely needs to be configurable. ... View more

I have just started looking at using the print widget within a WAB app for a customer and 100% agree that this needs to be improved as the option to use a custom print service hosted in ArcGIS Enterprise is not going to work for the majority of customers who are using ArcGIS Online, mainly because they do not have ArcGIS Enterprise due to cost. My feeling is that these customers are paying for a service and should expect that service to be able to do the basic things, like printing to an acceptable level. Currently this isn't the case as using the Print Widget with the ArcGIS Online print service has the following issues: The default layouts are poor and do not result in a professional looking print - Esri must have somebody that can design a better set of default layouts, so this would be relatively simple to fix. The Attribution shown on the map only includes the basemap attribution, and not attribution from operational layers (note that this attribution is shown when viewing the map). The print widget allows for adding copyright text, but what end user is going add this each time they print? There are not enough configuration options in the print widget - basic things like: Setting what layouts and formats are available; Setting what elements are included - title/scalebar/north arrow/scale text etc These are quite basic requirements that our customers are asking for and we cannot go back to them and say they need to purchase an expensive ArcGIS Enterprise license to acheive them! ...

We are also going to hit this problem with a customer that wants to filter accident features based on a related table (e.g. vehicles involved). Their relational model is very simple, with just one or two tables related to a layer by a 1-M relationship. However, currently the Filter widget doesn't support filtering by related records and although the Query widget allows for quering a table and then viewing related records, this isn't what the customer is asking for. I agree that there needs to be much better support for related records as it's not always possible to sensibly flatten the data structure to work around these issues. ... View more

Similar buffer functionality exists in some of the other widgets (Near Me and Incident Analysis), but is missing from the Select widget. Buffering would be a really useful addition and relatively simple to implement I would have thought. ... View more

Hi Andy No - we didn't ever get to the bottom of this and have instead worked around these issues by repeating the request a number of times if unsuccessful. Generally this works, but we still get the occassional instance, perhaps once a week, where it still fails, even after several requests. My feeling is also that it's something internal to ArcGIS Online, perhaps a load issue where one particular server or database does not respond within an internal timeout. I would have thought Esri would be monitoring these things within the platform, so must be aware that it's happening. You could probably work around the issue in a similar way within ArcGIS Runtime, by re-trying failed requests. Sorry I can't be of more help. John ... View more
