AJAX and Internet Explorer

[Patrick Klein <pa...@bi-so.de>]

Hi!

I'm still working my way through ajax functionality in tapestry 4.1.1 
and stumbled upon the following behaviour:

If i'm accessing my test-page using IE the ajax-functionality seems to 
fail. The first call of an asynchronous EventListener works (at least 
kind of) but e.g. the "dynamic" PropertySelections on the page are empty 
afterwards. If i reload the page after this call the values stored in 
the page look sane.
However, if i do another change one of my selections which have an 
EventListener "connected" to without reloading previously, the whole 
thing breaks down. This can be a grey layer above the page. On the Page 
the Message "ERROR [time] Remote server exception received" is visible.
Alternatively to that behaviour an Exception is thrown into catalina.out 
(not always):

Failure to export classpath resource /dojo/dojo.js.


      Session id    : A895E1D4E7664A94DE4C555069C376FA

Exceptions:

org.apache.catalina.connector.ClientAbortException

java.net.SocketException: Connection reset
java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:96)
java.net.SocketOutputStream.write(SocketOutputStream.java:136)
[...]

Everything works as is should when i use firefox

Opera shows a completely different behaviour:
The adjusted PropertySelections on the page get rerendered by 
updateComponent... at least kind of. After the update is over, the 
listboxes contain the correct ammount of selects but the description is 
empty... On the bright side, all the intended functionality works.

Could anyone here help me out with the IE related problem?

Thanks in advance :)

Patrick

Interesting.  I've seen this exact same behaviour in a little test app
I wrote.  In my case, I used a MultiplePropertySelection with a
renderer that renders the component as a multiple select box.  I get
correctly sized select boxes, but the labels are all empty.  I never
bothered to investigate the problem, I'm afraid, but I thought it
might help you to know that this isn't behaviour that is unique to
your app.  Id throw in some source code, but it is heavily dependant
on db schema and a dataset in the db, so I wouldn't be able to build
it, in any case.

Oh, in my case, I'm using the following tap 4.1 jars:

tapestry-framework-4.1.1-20061017.225719-37.jar
tapestry-contrib-4.1.1-20061017.225719-37.jar
tapestry-annotations-4.1.1-20061017.225719-37.jar
