Hi there !
Have a simple GWT's TextBox, using getText() and setText() manipulations via Observers.
Have one onClick event, and try to fetch some values from 2 Observers (simply modifying TextBox with Observer's internal setText(), getText() ), but unsuccessful, TextBox keeps it's old values.
I could notify updated TextBox's values inside the Observer, but how to deliver these TextBox's updated values via onClick event ?
Is there any specific use of Observer pattern in GWT ?
How to link several Observers on one event ?
Thank you all for useful feedback ! :)
