Ravi Mendis 33.1 1 == What is ERJQuery? ==
2
Ravi Mendis 87.1 3 ERJQuery is an alternative Ajax framework for WebObjects applications.
Ravi Mendis 65.1 4 It's is a [[jQuery>>http://jquery.com/]] version of [[ERPrototaculous]].
5 ERJQuery and [[ERPrototaculous]] are mutually exclusive frameworks. In other words, you may only use one or the other.

53
Ravi Mendis 81.1 54 ERJQuery embraces the stateless model Ajax offers in exchange for simplifying the work WebObjects has to do - it's a win-win
Ravi Mendis 65.1 55
Ravi Mendis 71.1 56 So you may observe one notable difference between ERJQuery and the Ajax framework is in the way it handles ajax responses.
Ravi Mendis 73.1 57 In ERJQuery, updates and actions break with standard WebObjects behaviour by being pseudo-stateless just like [[ERPrototaculous]].

Ravi Mendis 51.1 59 == Compatibility ==
60
61 ERJQuery can not be used with WebObjects 5.3 as it is dependent on the hooks for ajax added to WebObjects with version 5.4.
