S2: basic question on rest plugin
Hello All, I'm experimenting with the rest plugin (2.1.8) using the example struts2-rest-showcase as a starting point. I wanted to implement a simple search such that a URL like http://localhost:8080/struts2-rest-showcase-2.1.8/orders?amount=66 returned a list of order with the amount of 66. I approached this by adding an amount property to the controller and corresponding setter method and then modifying the controller's index method to use that value to constrain the results. Problem is that the amount never gets set either on the controller or on the model. Can someone please help me understand what's going on or suggest a better way to approach this problem? Thanks! --john - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Thanks for your reply Martin, I think I now have it working using the attribute
on the model.
