Hi, I have a dynamic Layer created by joining LayerDataSource and QueryDatasource. Everything seems to be OK, it has correct attributes and values. But when I try to apply ClassBreaksRenderer the default symbol parameter is not working at all. I mean, polygons with values that are defined with class breaks are coloured as they should be, but polygons with value „null“ are just blank. According to api reference this should be the case that default symbol from ClassBreaksRenderer is applied, but it is not. I am sure that symbol used for default symbol is ok, I have tested it on another features and I am sure that polygons with “null” values are present in the dynamic layer since I can see them from info window click. Any idea, comment, or help will be very appreciated… ... View more

I am trying to display attribute infos and attachment in popup window. It can be quite good handled by code selected as correct answer here (https://community.esri.com/thread/159806).   Basically you create two event handlers for “click” and “query-attachment-infos-complete“ and in second one you set content of infoTemplate. The problem with this approach is somehow „cosmetical“, but I would like to solve it. If you click two features that are close enough to each other you get a popup with label like „1/2“ and arrow that is supposed to switch popup conten to feature „2/2“. The problem is that on feature 2/2 the content (attachement url, or thumbnail) is the same as for feature 1/2 . It is probably because in handler for “query-attachment-infos-complete“  you set infoTemplate.content for one feature and that infoTemplate is used for second feature as well. So I am wondering if this could not be better solved with similar approach as in the tutorial here: https://developers.arcgis.com/javascript/jshelp/intro_formatinfowindow.html (at the bottom of the page, after Deferred Object bullet). In this approach you set content for infoWindow by function, let’s call it getTextContent(graphic). And inside this function you can run method featureLayer. queryAttachmentInfos(OBJECTID) which return value is deferred object. So you can implement callback function and get attachement url. I am just totally lame to get attachement url from that callback function into return variable for getTextContent function. The scratch version is like this: function getTextContent(graphic) {   var deferred = editLayer.queryAttachmentInfos(   graphic.attributes.OBJECTID,   function (attachemntInfos)   {   var attachmentUrl = attachemntInfos[0].url;   return attachmentUrl;   });   //I wish this would be attachmentUrl...   return ???attachmentUrl } Any help,idea, comment would by very appreciated. ...
