RE: Struts2 - OGNL - access bean property in model object
Hi Franciou, I have a clarification here. If model is initialized in prepare method, then it will be called for every call of other Action invocation methods in action class like add ,edit delete and save button actions. What can be done if I want prepare method to be called only for the first time when page loads and doesnt to be called for other button actions (CRUD).
