Guys, there is a pretty good weather WMS service available which I want to use in my Flex Viewer (2.3.1) map. Unfortunately I can't get it to work. I see a time stamp in the upper left corner, so it seems that the connection in general is ok. But there is no map visible.
It works fine in ArcMap/ArcCatalog and I took all the information from there.
Yes I'm having a similar issue with the flexviewer. This is what I have discovered.
My basemap is a bing map so it's projected in web mercator (102100). However the wms doesn't support that so you're to specify the wkid in the layer configuration.
However when I look at the calls being made in firebug it doesn't seem be re-projecting the bbox it's sending to the wms server. In response the wms server is send back a blank image.
for example here's the wms call when I don't add the wkid
So best guess I have, DStajan hit it on the head that your WKID may have been incorrect (4326 doesn't return anything, but 32632 and 32633 both do), and you seem to be using the wrong name for visible layers (ArcCatalog returns ECMWF-IFS_2:GRD as the name for Wind [m/s] when you look at its properties).
