the printing alone makes the upgrade worthwhile but...

what's a workaround for map.units going away? i was using that test whether to display degree symbols for coords (among other things). gleaning it from the map's spatialReference doesn't seem doable, as wk text isn't always available.


thanks.

never mind, found the thread in the beta forums.

still & all, having units easily available in the map is pretty convenient. maybe you might add it back?

It looks like the WebMapUtil does not trigger createMapByIdComplete anylonger after executing webMapUtil.createMapById... Am I the only one getting this issue?
I'm using flex 4.5..

I tried to copy/paste the sample as well and have the same issue...

I started recently to work with the air application builder v3.0. I am a little surprised about changes/removals in the 3.0 API. Why is it not possible to keep all old elements? Then I would expect that I can just work with everything new in the newly build tools and keep everything old as it was. An upgrade would be easier. Can anybody help me with experience how to upgrade earlier widgets for the viewer to v3.0? They are not opening on click. I found the general information about the changes and some earlier tips and tricks for 2.xx migration.

just found the information for upgrading your viewer code  that should at least solve the opening, all others I have to see once I get them started.

Another good page would be the "What's New in 3.0 API" - http://resources.arcgis.com/en/help/flex-api/concepts/index.html#/What_s_new_in_ArcGIS_API_3_0_for_F...

THERE'S A BUG IN API 3.0 WITH WMTS PROTOCOL.
THE MAP IS TRANSLATED RESPECT THE COORDINATE.
A SIMPLE TEST IS SWITCHING THE BASEMAP FROM FLEXVIEWER FROM WMTS TO WMS BASE MAP.

THERE'S ANOTHER TYPEERROR ON LOADING WMTS MAP IF (I SUPPOSE) THE API CAN'T FOUND IT:
REPORT THIS ONE (in italian sorry):
TypeError: Error #1009: Impossibile accedere a una proprietà o a un metodo di un riferimento oggetto null.
