In some of my editors, I'm implementing ValueAwareEditor<P> and using provided proxy value in setValue to obtain editor-specific data (most simple example would be to get suggestions for some sub-editors). Problem is that proxy instance that I was given in setValue is already edited in driver's RequestContext, so I'm unable to use it as parameter in another context (for obtaining suggestions). Error is well known "IllegalArgumentException: Attempting to edit an EntityProxy previously edited by another RequestContext".
My current workaround is to first obtain fresh instance (via RequestContext.find(EntityProxyId<P>) and then use that (frozen) instance for performing my initial request (e.g. MyRequest.getSuggestions(P)). Drawback is that I have one unnecessary round-trip to the server. Another solution wound be to refactor getSuggestions method to accept only id and rebuild full object on server side, but that seems to me as working around RequestFactory instead of using its provided services. Least feasible solution is to propagate frozen proxy instance from top level editor all the way down editor hierarchy, but that leads to spaghetti code. I know that RequestContext holds original (non-edit()ed, frozen) instance for every EntityProxy (for calculating diffs that it needs to send to server) - is there any way to get that original proxy from edited()-ed instance? Any other suggestions? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
