Hi, I'm stuck wtih a problem where the valueStackFactory is null, and this causes DWRValidator to fail. I had posted the stacktrace earlier, but didn't get much responses. Please confirm some of my assumptions reg the initialization process, so that i can do some meaningful debugging: 1. Dispatcher.init() has a container.inject(*this*); - which i'm assuming sets all properties that are annotated with @inject, like :
@Inject *public* *void* setValueStackFactory(ValueStackFactory fac) { *this*.valueStackFactory = fac; } 2. StrutsPrepareFilter calls the Dispatcher.init() right? - how long in the request lifecycle does the injected objects live? -- ex: i've DWRServlet that's invoked after both Prepare and Execute filters, but at that point valueStackFactory is null ; where does it get destroyed , and how will i ensure that i've a handle to it in the servlet? 3. In a normal action invocation (ie non-DWR), the extraContext .containsKey(ActionContext.*VALUE_STACK*) is true, while when the same is invoked via DWR, this entry is not added to context map , while the other keys like request, session, atttrs etc. are all present. Due to this, the stack creation is attempted , i.e stack = valueStackFactory.createValueStack(); and i get the dreaded NPE. Any inputs on how to set the valuestack or valuestackFactory at the right point in the flow will solve my problem. Thanks, Joseph
