I'm planning to develop a web based ERP, which should be full-ajax and with desktop-like UI. It will be a data-entry & data-report application. For developing it I'm considering all technologies.
GWT: I saw that with GWT Designer you could create cool UIs, but databinding seems to be too complex
JSF: Netbeans no longer supports the visual web editor
ZK: supports databinding in a relatively easy way, and has got an Eclipse-based visual editor
Some people talk about REST + javascript as a winning choice
I'd like to have your opinion about what could be the right choice.
Thank you very much in advance!
