Problem with asynchrounous updates
 
|
All,
I am trying to build a page that updates asynchronosly in the background as users interact with the page. Sort of like the google translation xforms example. My problem: ***************** 1. Load initial page 2. Click on 'negation' 3. Expect page to be updated and get.next.expression.editor.tokens.xpl to be called (note the debug statement) Instead, the tomcat log displays this: 2006-08-18 22:19:37,514 INFO org.orbeon.oxf.webapp.ProcessorService - /expression/next - Received request 2006-08-18 22:19:37,524 INFO org.orbeon.oxf.webapp.ProcessorService - /expression/next - Timing: 10 - Cache hits: 156, fault: 3, adds: 0, success rate: 98% 2006-08-18 22:19:37,534 INFO org.orbeon.oxf.webapp.ProcessorService - /xforms-server - Timing: 60 - Cache hits: 23, fault: 2, adds: 1, success rate: 92% But the get.next.expression.editor.tokens.xpl is never called. On further inspection, I decided to change the submit url from 'expression/next' to 'expression/next2' in the view, in an attempt to see if something would brake. All I got was this from tomcat: 2006-08-18 22:19:37,514 INFO org.orbeon.oxf.webapp.ProcessorService - /expression/next2 - Received request 2006-08-18 22:19:37,524 INFO org.orbeon.oxf.webapp.ProcessorService - /expression/next2 - Timing: 10 - Cache hits: 156, fault: 3, adds: 0, success rate: 98% 2006-08-18 22:19:37,534 INFO org.orbeon.oxf.webapp.ProcessorService - /xforms-server - Timing: 60 - Cache hits: 23, fault: 2, adds: 1, success rate: 92% So my problem is probably in the view page, but I am unable to see where I have gone wrong... Any insight would be greatly appreciated !

Henrik,
When something goes wrong with XForms, be sure to enable XForms debugging in log4j.xml: <category name="org.orbeon.oxf.xforms.processor.XFormsServer"> <priority value="debug"/> </category> This will give you a detailed log of pretty much everything the XForms engine is doing. In time, we hope to build a nice client-side console for this, but for now you have to use the logs. -Erik Henrik Pettersen wrote: > All, > > I am trying to build a page that updates asynchronosly in the background > as users interact with the page.

In reply to this post by Erik Bruchez
All,
looking at the logs for the xforms instance (thanks, Erik), I find this message: "Body received with non-XML media type for replace="instance": text/html" Can you specify the mediatype on the submit? Am I doing something wrong, or could this be a bug? Thanks!

Henrik,
This is the mediatype used by the service that sends you back the XML document. It should be ideally be application/xml. How is your service implemented? Does it set a mediatype (content-type)? -Erik Henrik Pettersen wrote: > All, > > looking at the logs for the xforms instance (thanks, Erik), I find this > message: > > "Body received with non-XML media type for replace="instance": text/html" > > Can you specify the mediatype on the submit?

Re: Problem with asynchrounous updates

Erik,
I looked into this a little further, and I found curious problem. When you are doing these asynchrounous calls to services, and the service for some reason fails, what is returned to the requestor is an error html page with content type txt/html. This response then fails the tests in XformsModelSubmission (contentype applcation/xml, return code 2xx) which throws an exception. However, the contents of the error page from calling the service seems to be lost, which leaves you with little clues for what happened. In my example, I have a bogus model reference in the pageflow. Are there some logs that I have not enabled? Should the error page from calling the service be displayed to the user?

Re: Problem with asynchrounous updates

Henrik,
You can: o Retrieve the error message body from XForms using event('body') available when you handle xforms-submit-error. (Note that event context information names defined in XForms 1.1 are not finalized yet, in particular "body" may be renamed "response-body" in the future.) o Put a debug attribute in config/error.xpl o Setup another Servlet in web.xml that handles all your services and has an error processor returning an XML error instead of an HTML one, although this is a slightly heavier setup. Possibly in the future the default error.html could return an XML error based on an "Accept" header set during XForms submission, i.e. if there is an Accept header but no text/html, the error could be simply formatted as XML. -Erik Henrik Pettersen wrote: > Erik, > > I looked into this a little further, and I found curious problem. > > When you are doing these asynchrounous calls to services, and the > service for some reason fails, > what is returned to the requestor is an error html page with content > type txt/html. > > This response then fails the tests in XformsModelSubmission (contentype > applcation/xml, return code 2xx) which throws an exception. > > However, the contents of the error page from calling the service seems > to be lost, which leaves you with little clues for what happened. > > In my example, I have a bogus model reference in the pageflow. > > Are there some logs that I have not enabled?
