I have been working with the new ArcGIS Images for ArcGIS Online (https://www.esri.com/en-us/arcgis/products/arcgis-image/options/arcgis-online) which are well worth trying out if you haven't already. However, it seems that you cannot use the Print Widget in a WebApp if you have one of these images open in your Web Map. I am trying to export an image from my map, primarily a geotif, but get an unspecified error whenever one of these images is turned on.   Anybody have any suggestions how to get round this, or at least confirfmation that they get the same behaviour?

The Summary widget is great for getting a quick summary of numeric fields for all features in the current map display. Or, you can specify a field in your feature layer to filter on and return a summary for individual features. But, does anyone know how to return a summary on a group of selected features within the current map display? I have a series of survey polygons (all in the same feature layer) in my map and I would like to be able to select a group of discrete surveys and return summary statistics on just those surveys. This may require a custom version of the Summary Widget and I was wondering if anyone was working on such a custom widget? ... View more

Can you advise a newbie to the Flex API how to count the number of points in my map service. My service has approx. 4 million points and I would like to use an interactive on-screen polygon to select a group of points and then to return the actual number of points selected. As my points are one of two types (A and B but all in the same layer) I would ideally like to retrieve the number of A points and the number of B points as well as the total. I have been able to modify the 'chart widget' to return the number of points using the {=COUNT} parameter but I also end up with a fairly meaningless chart which I don't really want. I am not a developer so ideally I'm looking for an existing widget that I can tweak in the .xml file. Any suggestions? Thanks in advance. ... View more
