More infinite loops when upgrading to 3.6

Hello.

I'm upgrading from 3.6.0beta.200708070321 to orbeon-3.6.0.200712061930.
When I initially moved to 3.6.0beta I needed to add a reload flag on my
actions to stop xforms-value-change events from causing repeatedly
reloading instance data (see
http://www.nabble.com/Problems-upgrading-to-recent-snapshot-td12051152.html#a12052751).
I now find that after upgrading to the release version of 3.6.0 my fix no
longer works and I'm getting repeated reloads again.

In investigating this problem I've arrived at a situation (demonstrated by
the attached sandbox file) whereby I load two nearly identical files as
instance data and set up a select on each which will cause them to reload
when the select value changes.

However in one case the reload works as expected but in the other it causes
(what I assume to be) an infinite loop. The xml data files have been
created by combining bbc new rss feeds and some of my own data.

Any idea why two nearly identical files case such different responses?

(P.S. I'm not even sure if this is anything to do with my problem of
reloading instance data on xforms-value-changes).

Many thanks,
Chris.

Adding an <xforms:refresh/> after the xforms:send, as in the attached
file, solves your problem. But I don't think we shouldn't have to add
this refresh, so I created a bug for this, with a reference to your
example:

Thanks Alex that does work (although I agree that I probably shouldn't need
to do this).

However I was more concerned with why this is happening in my test case -
if you view the two xml files that are loaded
<http://www.ilrt.bris.ac.uk/~cmcpb/testok.xml>
<http://www.ilrt.bris.ac.uk/~cmcpb/testbad.xml>
You'll notice that they are identical except the 'good' xml file has an
extra bit of xml in:

...
<link>http://news.bbc.co.uk/go/rss/-/1/hi/sci/tech/7177181.stm</link>
...

If there was any problem with loading of xml files I would assume that the
smaller of the files would be the one that works not the larger. Can you
give me any insight into why this would be? My guess is it must be
something to do with the physical size of the xml file being loaded.

Chris.

Hi,

It seems that there is a problem with setting a focus on radio-button.
Attached example is tested in XForms sandbox and everything works fine for
input and combo box controls.

However, from some reason, focus is not set on radio-button.

Tnx,

Nikola

I am not sure why this works in the testok.xml case. What should
happen (and seems to happen in the testbad.xml case) is that after the
<xforms:send submission="reloadBadTestdata"/> a refresh is "scheduled"
to be done at the end of the action block. So then the
<xforms:setvalue
ref="instance('datachange')/dirty">true</xforms:setvalue> runs, and
then the xforms-value-changed is dispatched, which (since dirty =
true) runs the submission again. Hence the loop, which you can break
by forcing the refresh to happen just after the submission.

The issue is now fixed. You can try this out in the next nightly
build. For reference, this is the bug that Erik entered earlier for
this one:
