Yes u may say that i am using plain old html but this html is generated on the fly which is my desired result i dont have to do any page reload. for example take a case that i have to display a image of the user when he logs in so image of each user in the same directory but with different file name so we have a different url for every user req in the src attribute of the image tag but. so with gwt i have to send a xhr request. if it was a single request it would have been easy but in my form i have around 15-25 fields whose data has to be populated on the fly. so method best suited would be some how i am able to design the html page on module load only
what do u suggest??
