repeat / switch interaction

I had a form working that used a switch to toggle a button between
"delete" and "undelete" for a table row within a repeat. I then moved
the input controls for the row down into the cases to make the fields
non-editable when the button says "undelete". That part works fine, but
it broke a seemingly unrelated part of the form--the "add" button. Now
when I press the "add" button I get a cryptic message, "Object required".

On the mailing list archive I see other people having similar problems
with repeats and switches, but I see no resolution. Have I found a
limitation of Orbeon, or am I doing something wrong?

Please see the xform pasted below. (I tried uploading it to the sandbox,
but couldn't figure out how to send a link to it.)

Thanks,
-Jim

One more data point: when I add a new row and get the error, dismiss the
error, then change the instance inspector to the template instance and
then back to the person instance, the instance looks correct, but the
table is missing a row.

Am I using "repeat" and "switch" in a way I'm not supposed to, or have I
uncovered a bug?

Thanks,
-Jim

Yes, but it seems to be fixed in nightly builds already: I repro your
problem online, but not with the latest code.

Erik,

I installed the latest nightly just now, and it's still broken...

My sure you force-reload the page (ctrl/cmd-shift-f5 or ctrl/cmd-shift-
reload depending on browser), or empty your browser cache first. Does
the problem still persist?

It's still happening in IE. I tried it in Firefox 3.0b5 and it works okay.

Well, sort of okay. I can't figure out why the added row always has the
"undelete" button, which is not the default case. Any ideas?

I've been probing into this a bit further in FF 3.0b5. When I add a few

rows and then mark a row for deletion, the first row in the repeat flips
to the wrong switch case. Is this a bug or something I'm doing wrong?

Oops, I misspoke. I meant to say, "When I add a few rows and then delete a row, the first row in the repeat flips to the wrong switch case." It's as if pressing the delete button toggles the first row after the deletion happens. Marking the "Fido" row for deletion works correctly.

I found a way to make it work, but I still suspect this might be an Orbeon bug.

The work-around was to put an "if" in the toggle, as follows.

<xforms:toggle case="deleted" if="@action = 'deleted'"/>

This makes it toggle only for rows that already existed and should not get deleted within XForms (i.e., not the ones where "@action = 'added'--those can really get deleted).

I think I found yet another bug in Orbeon. When I delete a row, the "xforms-value-changed" event fires on the fields I haven't changed, which causes them to have the "@action='edited'" attribute. :-/

I never heard anything about whether I'm doing something wrong or Orbeon has a bug.

In the following XForm, If I add a pet, let's say "Lucy", and then delete it, the "xforms-value-changed" event fires on the "Fido" row, which flags his name and age as having been changed.

Could someone please confirm whether or not this is a bug? Is there a way I can fix it?

Thanks,

Re: Re: repeat / switch interaction

Jim,

It kind of is a bug. At the moment, the XForms engine doesn't really
know, when you deleted a repeat iteration, that this causes subsequent
repeat iterations to "slide down". The UI part of the XForms engine
only sees that on the first row, instead of having "Lucy", you now
have "Fido", so fires a value change event.

There is certainly a way to fix it, and we would like to fix this in
the future, but it is fairly involved.

Erik,

Is there something I can do to work around this in the meantime?

If we paid for a support contract, what are the odds this could get
fixed soon? I think this bug would make it difficult to use Orbeon for
our existing instance-document-editing implementation and we would have
to do something special on the server side to compensate.

Thanks,
-Jim
