Ok thanks Jesse I think I figured out what the problem was. My model values were initialized in the pageBeginRender listener, thus resetting the model value I had just modified in the event listener. After I switched to @InitialValue annotations instead, it worked. This brings a question: what is the proper strategy to initialize property values when using ajax submits? Does finishLoad() does the trick? I am still a bit confused about when all those methods/listeners are invoked and in which order
I am now also facing another (probably unrelated) problem : the event is properly triggered and the select content is updated... but only once. The second time, the event is not fired, and no XHR request is sent to the server. I think I remember reading something about this in the list, but I couldn't put a hand on it. Do you have any idea? Thx again for all the great job. Although I'm having a tough time making it work, it really is a nice programming model Ch. 2006/9/14, Jesse Kuhnert <[EMAIL PROTECTED]>:
I'm not sure. Something sounds wrong. How does the work when not using ajax? I mean, are you sure you are hitting problems related to dynamic behavior or more with dealing with normal api semantics? The debug should explicitly show you the content it is updating a component with. If it has debug statements showing the content then it could be your listener method doing something funky. Mark Reynolds has become my favorite bug reporter of all time. His issues usually come with completely self contained projects that I can invoke "mvn jetty:run" on to see all the gory bug details (documented examples and all) for myself. One such issue was unrelated to what you are experiencing but does include a good example of doing exactly what you are trying to do. Perhaps it will be of some help. http://issues.apache.org/jira/browse/TAPESTRY-1072 Let me know if the documentation hasn't made something clear after you try it out and I can attempt updating with whatever relevant information there is.
