Identify/Info of Multiple Items of the Same Layer (in Flex)

AlexZhuk — Thu, 07 Apr 2011 18:55:25 GMT

Is there a way to get information of several items/features of the same layer when they (items) overlap? It's a standard part of the Desktop or .Net Server. is this possible in Flex?

Alex,

If you want to identify multiple layers or everything in your case, than all you have to do is set the identifyParams.layerOption = "all".

Thanks for your suggestion. Unfortunately, I'm doing it in the Viewer for Flex, so I can't make your edit.
All I need is to get a choice of multiple Infos on multiple overlapping items in the same layer, see illustration here https://gis.itsi.com/SimpleInfo1.PNG. Right now I only get one item's info. And it's not necessarily the latest in my table, or biggest, etc. Just random, I guess.

Alex,

Oh I guess that it would have helped if you said that you where trying to do this using the SimpleInfoWinWidget. It uses whichever geometry is on top as it gets triggered by mouse events. Why not use the identify widget?

Robert,
Pardon my ignorance, where can I find it? Identify Widget is not a part of standard Viewer 2.2.

Alex,

You will find lots of user developed widget in the Flex Viewer code gallery.

Thank you very much!
Have a nice weekend.

Robert,

Would you be so kind to suggest what I need to put between the <name> brackets for the (0) sub layer from my multi-layer service (shown below in REST):

Home > EPA > CR_Mercury (MapServer)
EPA/CR_Mercury (MapServer)
View In: ArcMap ArcGIS JavaScript
Service Description:
Map Name: Main
Legend
All Layers and Tables
Layers:
- Total Hg (Nevada) (0)
- Filtered Hg (Nevada) (1)
- Total Hg (USGS) (2)
- Filtered Hg (USGS) (3)

I tried "CR_Mercury_msd", "Total Hg (SW/GW, Nevada)", and some other combinations but nothin works so far. BTW, all these four sub layers (0), (1), (2), and (3) are "feature" layers in the main config.xml file.

Thanks!

Alex,

It is suppose to be the EXACT name of the layer as seen in the REST Services directory. So in your case it would be

Total Hg (Nevada)

for layer 0.

Robert,

Actually in my example yesterday I tried to simplify my layer names for you and messed up at the bottom. My real layer names are even more complex, something like
Filtered Hg (SW/GW, Nevada)
with comas, parentheses, and slashes. I typed them exactly in the widget (copy/paste), then I eliminated all "problematic" characters and replaced them with underscores - to no avail. But still thanks for the pointer. I'll keep trying. Does it mater that I work with FeatureServer layers?
I really appreciate your help!!!

Alex,

Every time you are making changes to the layers name in ArcMap are you then restarting the map service and Clearing the REST Service Cache?

Re: Identify/Info of Multiple Items of the Same Layer (in Flex)

AlexZhuk — Sun, 10 Apr 2011 05:30:03 GMT

Robert,

Yes, I do clear browser cache and REST cache, and restart the service, and even restart the IIS. Nothing works. I guess, my application will be without any Identify tool. I spent so much time fighting with every little detail on this Flex exercise. It's alright... I'm about to give up...

Thanks for all your help,

One last attempt.
My layers have tokens in the config.xml file. Do I need to somehow specify tokens in the IdentifyWidget.xml file too? When I use the Identify tool and make a selection on my map, the tool then switches to the results window, which remains blank.

Thanks.

Alex,
I have the same issue, did you have any luck? Worked perfectly before I secured my service. I have all my layers as operational in one dynamic service (not individually listed).
Cheers
Steve

Steve,
I couldn't make it work until I UNsecured the service...

Guys,

As you could probably tell by my lack of answers I do not use secure services so I can't help with those questions. As you both probably also know you just can't enable security on ArcGIS Server and then easily turn it off so I won't be messing with my development server or production server to enable security. Maybe others that use security will chime in eventually.

Hi Robert,

Thought for sure I saw a post somewhere where you describe how to turn off the "move to top on hover" event that moves the geometry to the top when you hover over it. I have overlapping polygons in my service, and is sorted by area (smaller polys on top). When it loads into flexviewer (using 2.5 now), the graphics come across as they are sorted in the service. However, when I hover over it, the first one I hover on moves to the top and I can no longer get the feature underneath to move to top.

So, figure if I can turn off this feature, then the smaller polys will stay on top so I can InfoTemplate them. Like I said, thought I saw a post on this, but this is the only related post I seem to be able to find today. Any chance you could point me to the other post, or to the right section of code to handle this?

Thanks yet again,

Rhett

Would use the identify widget, but am taking advantage of your wonderfull multiimagefield on these layers.

Rhett,

Unfortunately that is a problem. The Attachment Relate Info Window Widget is working with the graphics that are already in the map. To disable the graphics autoMoveToTop property you have to have access to the graphic when it is added to the map. Here is an untested workaround:

in the MapManager find the addLayerToMap function and then the case "feature": and add these lines:

                        if (label == "your layers label")
                            featureLayer.addEventListener(GraphicEvent.GRAPHIC_ADD, disableAutoTop);
// this should be added right before map.addLayer(featureLayer);

Then add this new function (but not inside the addLayerToMap's code block):

            private function disableAutoTop(event:GraphicEvent):void
            {
                event.graphic.autoMoveToTop = false;
            }

See if that works.

Thanks Robert,

Once I added the import statement it seems to be working.

import com.esri.ags.events.GraphicEvent

Still have some testing to do, but it appears to give me what I need.

Thanks again,

Rhett
