Viewer for Flex 3.1??

JayHalligan — Tue, 13 Nov 2012 13:20:23 GMT

Does anyone have information on what will be included in 3.1?

I am mostly wondering whether it will include:
*Custom text element in advanced print layouts
*Dynamic Legends in custom print layout

But you can already do both of those things in Version 3.0?

I dont believe they are available in the compiled version of 3.0. I could be mistaken but I have not found a solution.

Both of those things you mentioned aren't really flex-related. Those things are determined by your .mxd's that are used by the Export Web Map geoprocessing task on your ArcGIS Server 10.1 instance.

Well I can create a custom text element in my custom layout, no problem. My problem is having the customtext input parameter in the flex widget. Also with the legend...If there are no features in my custom layout, I dont have the option to turn on/off the dynamic legend checkbox. Maybe Im still missing something here.

Oh, I see what you mean now.

How many input text parameters do you need?
In the ExportWebMapForm.mxml, you can just add as many mx form items as you need with the title, copyright, author, etc.

Regarding the legend, just have one layer in your template and leave it turned off, and then add the legend and check the dynamic checkbox.

Perfect. Ill give it a shot.

Still does not seem to work. Even with the dynamic legend (only show what on screen) checked before exportwebmap, it is not honored when exporting in the flex viewer.

Try adding the REST service to ArcMap to your template .mxd and checking it manually.

Sorry again about the confusion but I am actually trying to "Only show classes that are visible in the current map extent".

Ok, I think we're on the same page.
If you add a REST service in ArcMap, you will notice in the Layout View, In the Legend properties, for the layers that are within the REST service, the box is grayed out for "Only show classes...".

Therefore, the only way you can do it through a web API is to have access to the actual data being served out by the REST service. Then, you will want to replace the REST service with similarly symbolized data using data accessible to your ArcGIS Server Instance. This will then do what you want. The issue is that you must have the actual data, instead of just the REST service.
