Try saving the controller first , go into Setup, Apex Classes and save it there,
then save the visualforce page, that worked for me

Somehow in the development mode, the quick fix did not recognize that mytask was returning a task, since it builds this as a string in quick fix mode.

I have filed a bugreport, i was not able to get this to save
ESES
I think the problem is that you are calling your apex class Task, and thats what gets returned instead of the SObject Task.
Try renaming your class to something else like MyTask.
Ron HessRon Hess
Yes, i see now.

the class Task that you defined was returned when you made the call

 task = new Task();

rather than creating an sobject with all it's fields, you created an instance of the class (called Task) of your own definition.
amar joshiamar joshi
yep

its working

i have  givan class name and instance of class name same thats why it confused and give the error

thanks all for helping me.
