Hi, Thanks for the answer and sorry for the delay.  I suspected that might be the case.  The issue was found by our test team as they were testing the search based on the properties of a number of sample features and Shape was one of those properties.  Therefore, in the real world scenario, there may well not actually be a use case for needing to search on the Geometry attribute so we are just going to park it as a known issue. Again, thanks. ... View more

Hi, I came up with a work around.  First I considered a geoprocessing task and wrote some python that produced a list of attachment names to be returned but this had some downsides.  One being that it required knowing about the location and structure of the geodatabase, which is organised differently from the published service, so you can work out the layer ids the attachments related to.  It was also susceptible to changes made by the GIS team as would need to be manually changed if they moved things around.  Finally, of course, it would only work for map services on our own GIS servers where we can actually write our own geoprocessing tasks. So, instead I wrote an indexer service.  It's just a C# console application that runs as a Windows service.  It requests the MapServer json for a service to get the list of layers, then for each layer gets the list of object ids then for each object id, gets the attachmentinfo.  If there are attachments, it puts the details in the database.  I then just wrote a WebAPI webservice that queries against this index, rather than directly against the ArcGIS server.  It works really well: the query is very fast and it can index any map service, not just our own.  Of course, the caveat is it's only as up to date as the last time it indexed the service, but that can be done as often as you need. ...

Thanks for your help - I've got it working.  To correct something I said earlier, the bottom most layer is 0, not the top most.  This makes the maths easier as you pointed out: the graphics and feature layers are always on top so don't skew the ids at all.  It's simply a matter of getting the index in the array of the layer you want to move and adding / subtracting.  It's therefore really easy to create up / down buttons that adjust the position of the selected layer. Thanks for your help! ... View more

Ah, I wondered if that might be the case.  I'll experiment with this further next week but I think that hopefully answers it - I'll let you know! Thanks for your help. ... View more

Hi Ken, Thanks for that - I had just come to a similar conclusion: that the layerIds are (I think) returned in their index order (or rather reverse order).  i.e. it will be the order the layers were added to the map by default, but the top most layer for repositioning is 0.  If a layer has been re-ordered then it will appear in a different index in the layerIds array. However, there is still something I'm not certain of.  There is also a graphicslayerIds property which returns the ids of all the graphics layers and feature layers: these layers aren't included in the layerIds array.  So say you had 5 dynamic map services and 5 feature layers on a map: layerIds returns [dynamicA, dynamicB, dynamicC, dynamicD, dynamicE] graphicsLayerIds returns [featureA, featureB, featureC, featureD, featureE] How would you know what index to set dynamicC to to move it above dynamic? ...

Yeah, I came across that too after I'd asked the question, but thought I'd leave my question up in case things have changed since then.  It doesn't look like they have and so I think it's just a case that the notes in the API are just a bit ambiguous. ... View more

Hi Jake, Thanks for a quick answer.  However, I don't see how that differs to the layer-add event - it looks like it will be fired every time a layer is added but the API says it is fired when a specified layer is added. Simon ... View more

I created a simplified page to show the problem - I basically just took the measurement sample code and changed it to load one of our own map services in SRef 23031.  However, the area measure worked properly! On the full application where the problem is occurring, I have determined that the measure-end event simply isn't raised when using the area measure tool.  It is raised when using the line and location tools.  I'll keep digging.  Any tips or advice to help diagnose the issue? Thanks! ... View more

Hi Jonathan, The geometry service is running on an ArcGIS Server Enterprise Standard install, version 10.21. The web application isn't yet finished so hasn't been uploaded to an external site.  However, I could put a quick example page together and just copy in the measurement related code.  I'll get this done ASAP next week and post the URL.  Thanks for your quick reply.
