I too don't know what geomajas is, and Flex may or may not be the best solutinon for it, but consider that Flex/Flash are not supported on iPhone, and probably never will be. Actually, I don't know much about Flash/Flex as well, but I am assuming that even though they are different products, they produce the same SWF end result, and require a Flash player/plugin on the client, and Flash is a huge CPU hog. Ever since I installed ClickToFlash (http://github.com/rentzsch/clicktoflash/) on my Macbook, I am a happy camper. So, if you don't mind geomajas to not be accessible to the largest mobile web platform, Flex/Flash may well be a good solution. -- Puneet Kishor http://www.punkish.org/ Nelson Institute for Environmental Studies http://www.nelson.wisc.edu/ Open Source Geospatial Foundation (OSGeo) http://www.osgeo.org/ Sent from: Madison WI United States. _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
