I'm pretty sure the answer is no, but I have a Collector layer that involves scoring Trees, so 1-10 for Artistic Interpretation, 1-10 for Style and 1-10 for the Evening Wear round. If the score is above, say, 15, some other stuff needs collecting. Any ideas how to do this in Collector?  Or do my users just need to add three numbers in their heads? ACM ... View more

I thought I had seen the last of these.  However, I am trying to retrieve the EXIF metadata of attached images using this code jseidelin/exif-js · GitHub  - it works when I run the example page and load in the full URL of the images returned via a " featureLayer.queryAttachmentInfos" command. However, the AGS server being a different domain to my site hits CORS issues - which I thought I had sorted by changes to web.config and adding the server name in with a "esri.config.defaults.io.corsEnabledServers.push" However, when I try to retrieve the data using a simple function         for (index = 0; index < attachmentPath.length; ++index) {             var image = new Image();             image.src = attachmentPath[index];                       image.onload = function () { // always fires the event.                 EXIF.getData(this, function () {                     console.debug(this)                     var make = EXIF.getTag(this, "Make"),                         model = EXIF.getTag(this, "Model");                     alert("I was taken by a " + make + " " + model);                 });             };            ....do stuff with the info returned         } I get XMLHttpRequest cannot load http://<<server name>>/arcgis/rest/services/test/emap2/MapServer/22/2009/attachments/8. Request header field If-Modified-Since is not allowed by Access-Control-Allow-Headers. All other requests to resources using the server name seem fine. I'm stumped.  All I want to do is to know which way up to display the attachments! ... View more

see Find attachments using task in JavaScript API But I've sort of moved on, so I thought I'd open a new thread. So, (as every sentence has to start with "so" these days) I am detecting if my layers have attachments on load with a call to the REST thingy, this is stored in an array, with the array index matching the LayerID When I go through the records returned in the results dataset of an ID task, I check the layerID of returned record against this array and if it has attachments I then do stuff. That's my first issue.  I used something like this                  if (layerHasAttachments) {                                              objectId = results.feature.attributes.OBJECTID;                         t = mapservice2 + "/" + results.layerId.toString();                         featureLayer = new esri.layers.FeatureLayer(t, {                             mode: esri.layers.FeatureLayer.MODE_ONDEMAND                         });                         //use queryAttachmentInfos to return into array the path of each attachment                                                 featureLayer.queryAttachmentInfos(objectId, function (infos) {                                                      if (infos.length > 0) {                                                           for (index = 0; index < infos.length; ++index) {                                     attachmentPath.push(infos[index].url)                                 }                             }                                                      console.debug(2);                          }                         );                                        console.debug(3);                  } However, the code carried on before the results came in -0 I get my debug 3, before my debug 2 - so I have issues then deciding if action is needed if a feature has an attachment. - So, first issue, how can I wait for the info from the "queryAttachmentInfos" before moving on? I had to move on, so every feature in that is in the results dataset that is in a layer that is enabled for attachments has a button next to the result.  This opens a popup where I show the photos (currently we only have photos, so I haven't done the code to detect attachment type).  My code is featureLayer.queryAttachmentInfos(objectId, function (infos) {         imagePopupHTML = "<!DOCTYPE html><html xmlns='http://www.w3.org/1999/xhtml\'><head><title></title></head>'";         if (infos.length > 0) {             for (index = 0; index < infos.length; ++index) {                 attachmentPath.push(infos[index].url)                 console.debug(infos[index])             }         }         for (index = 0; index < attachmentPath.length; ++index) {             imagePopupHTML += "<a href='" + attachmentPath[index] + "'>"             imagePopupHTML += "<img src='" + attachmentPath[index] + "' style='width:600px'></a></br>"                     }         imagePopupHTML += "<body></body></html>"         OpenWindowThumb = window.open("", "thumb", "height=" + popY + ", width=" + popX + ",toolbar=no,scrollbars=yes,menubar=no,resizable=yes");         OpenWindowThumb.document.getElementsByTagName('body')[0].innerHTML = 'Please Wait';         OpenWindowThumb.focus()         OpenWindowThumb.document.getElementsByTagName('body')[0].innerHTML = '';         OpenWindowThumb.document.write(imagePopupHTML);             }     ); So I get the URL and fling it into an basic HTML page - not elegant, but I am pushed for time and needed to show people that field collected data from Collector can be seen in the office in our browser mapping. If I use the raw URL for an image in Chrome, it detects the orientation.  IE doesn't.  So I am guessing that some metadata is stored with the image.  I have failed totally in getting it.  I tried a few add on chunks of code, but they didn't return what I was after.  So, that's the next question - Is it possible to query the server to get image rotation info (and other metadata) Many thanks ACM ...

Ok - I'm not sure if this more an issue with our setup rather than the code, as it is random. But sometime the creation of a TOC hangs - eventually I get a timeout error. I tracked this down and occasionally it seems to be hitting www.arcgis.com/sharing/tools/legend to get the legend - of course, with an internal URL it falls over. I have hacked the code to prevent this             //ACM hack             //if (this.rootLayer.version >= 10.01) {             if (1==1) {                 url = this.rootLayer.url + '/legend';             } else {                 url = 'http://www.arcgis.com/sharing/tools/legend';                 var i = this.rootLayer.url.toLowerCase().indexOf('/rest/');                 var soap = this.rootLayer.url.substring(0, i) + this.rootLayer.url.substring(i + 5);                 url = url + '?soapUrl=' + escape(soap);             } As I know my services are greater than 10.01 I can always do this section and rather than remove the 'if' totally I replaced the condition with 1==1 I also put a           console.debug(this.rootLayer.version) in the code - the times it fails this returns as empty However             console.debug(this.rootLayer.dpi) always returns a value, even when version is empty - other properties of this.rootlayer are also fine. I have no idea why it is happening, but this is my fix I thought I'd share. ACM ... View more
