Hello John,
thanks for the reply. Here is an example code that does not
work (Pasted below and attached the file as well). A function from the
main wxlua application calls filterFormActivate which sets up a simple
frame with 2 buttons and one static text and associates the button
click to SelTaskPress. But when the button is clicked the test()
statement gives an error. If that is removed then it cannot recognize
the frame varaiable in the wx.wxFrame(frame line after test().
Pleas have a look at it and let me know what is wrong.
Thanks,
Milind

It should be able to work and the environment is saved when the
event:Connect() is handled. Upvalues work for sure.
Do you have some simple example code of this for me to try.
