I have a flex app that takes data from a back end database then displays the content in one of 3 views.
These views are all in a viewstack which is instantiated in main.mxml
The method to get the data (remote object)is also in main.mxml.
The views rely on the data so how can I go about making sure that the data is loaded first before any of the views in viewstack are created / initialised to stop me having null reference errors?
When you get the data, you should have a callback function defined to receive that data (callback function is the function you put into addEventListener). You just need to call the function to create your viewstack after all your callbacks have been called.
The way I would do it is create an class field called numCallbacks. Increment this variable everytime one of your callbacks is called. Right after you increment it, check if numCallbacks == the number of callbacks you have. If true, create your view stack.
