Magento event observer not working on some machines

阅读更多关于 Magento event observer not working on some machines

问题 I cannot seem to figure out why my event observer works from my machine (and another coworkers) but not from other machines in the office. For example, I have an observer that listens for the event: controller_action_postdispatch_adminhtml_process_reindexProcess My code detects the event and runs some code. When I run the re-index process, my code executes. When certain other machines here in the office run the re-index, either the event is not fired, or my observer isn't detecting it. Why

How to test JavaFX (MVC) Controller Logic?

阅读更多关于 How to test JavaFX (MVC) Controller Logic?

问题 How do we properly write unit/integration tests for the JavaFX Controller logic? Assuming the Controller class I'm testing is named LoadController , and it's unit test class is LoadControllerTest , my confusion stems from: If the LoadControllerTest class instantiates a new LoadController object via LoadController loadController = new LoadController(); I can then inject values into the controller via (many) setters. This seems the only way short of using reflection (legacy code). If I don't

Checking session exists or not- mvc3

阅读更多关于 Checking session exists or not- mvc3

I was googling on Sessions and mvc3, and I found this link . To that question a marc-gravell answered The session only really exists during the processing of an action - I wouldn't expect it to be valid in the constructor of a controller. For example, the controller might (for all I know) be re-used between requests. I think that may not be the case by reading further on mvc requests and creation of controller, I found this : A Controller is created for every request by the ControllerFactory (which by default is the DefaultControllerFactory). So I think, Marc was incorrect and we can simply
