Modify Flex app (History limit)

TODO: User can load history on the map (for example, track for a week). He uses date pickup to specify begin/end of period. Now he can specify any period, that will overload server. You should show warning if user tries to load period is too long (for example, more than month) or too deep (for example, older than one year). Limitations depend on user role (demo or premium user). This should give warning both for loading track for map or loading report. General info: Modify existing Flex / AS3 application. There are number of tasks to do in this application. I will post each of them as individual project. Each individual task should take couple days to complete. I'm looking for experienced Flex / Flash / ActionScript developer, who will add new features and fix issues in existing Flex application (client side only). You will work in a team, others may modify app too, you have to cooperate with them. Source control is git. You will need Dropbox to sync git repo - [login to view URL] (+500MB Bonus space with this ref link). Application url: [login to view URL] Login/Password: demo/demo
