xforms:group/@appearance='xxforms:internal'

Alex/Erik,
    I'm using xforms:group/@appearance='xxforms:internal' but I noticed that the relevancy only applies to the xforms:controls. Is it possible, when the group becomes irrelevant to apply display:none to all its child elements?

Thanks

Ryan

Ryan,

Background: xforms:group/@appearance='xxforms:internal' is kind of a
hack temporarily introduced so that we can use xforms:group/@ref to
define a new XPath evaluation context around xhtml:tr. It is meant not
to have associated markup in the resulting HTML page.

Now how exactly are you using it, and would you have a simple case
showing what's wrong with it?

Erik,
    I'll work on a test case but I am using it around a xhtml:tr element, and want that row to disappear when the group isn't relevant

Ryan,

xforms:group around xhtml:tr used to control relevance won't work. We
have an RFE open on this here:

http://forge.objectweb.org/tracker/index.php?func=detail&aid=306259&group_id=168&atid=350207

The xxforms:internal appearance was introduced so that you could use
xforms:group around xhtml:tr, but for purposes other than controlling
relevance (like changing the XPath evaluation context).

Erik,
    I found that the tbody element is allowed between the table and tr elements, I modified the xforms:group to have an xxforms:table appearance, which generates a tbody instead of a span. This worked in my case, the only time I found a problem is when you have more than one directly nested xforms:group i.e.

<xforms:group>
    <xforms:group>
       <tr>...</tr>
     ...

This causes some table formatting to disappear, but it still functions correctly.

I've attached the two changes I made, if you want them

Hi Ryan,

Thanks for an interesting fix. I think it is good as a temporary
solution, but I am wondering if we want to include it or not. If we do,
that may delay a more advanced fix, which probably involves implementing
xforms:group in tables in the same way we implement xforms:repeat, by
allowing xforms:group to directly add and remove classes on <tr> and
even maybe <td>.

Erik,
    That would certainly be the preferred solution, it doesn't seem like many people are coming across the same problem as us so perhaps it isn't that big of an issue.

Thanks

Ryan

Hi Ryan,

Thanks for an interesting fix. I think it is good as a temporary solution, but I am wondering if we want to include it or not. If we do, that may delay a more advanced fix, which probably involves implementing xforms:group in tables in the same way we implement xforms:repeat, by allowing xforms:group to directly add and remove classes on <tr> and even maybe <td>.

Erik,
    I found that the tbody element is allowed between the table and tr elements, I modified the xforms:group to have an xxforms:table appearance, which generates a tbody instead of a span. This worked in my case, the only time I found a problem is when you have more than one directly nested xforms:group i.e.

<xforms:group>
    <xforms:group>
       <tr>...</tr>
     ...

This causes some table formatting to disappear, but it still functions correctly.

I've attached the two changes I made, if you want them

Ryan,

xforms:group around xhtml:tr used to control relevance won't work. We have an RFE open on this here:

http://forge.objectweb.org/tracker/index.php?func=detail&aid=306259&group_id=168&atid=350207

The xxforms:internal appearance was introduced so that you could use xforms:group around xhtml:tr, but for purposes other than controlling relevance (like changing the XPath evaluation context).

Erik,
    I'll work on a test case but I am using it around a xhtml:tr element, and want that row to disappear when the group isn't relevant

Ryan,

Background: xforms:group/@appearance='xxforms:internal' is kind of a hack temporarily introduced so that we can use xforms:group/@ref to define a new XPath evaluation context around xhtml:tr. It is meant not to have associated markup in the resulting HTML page.

Now how exactly are you using it, and would you have a simple case showing what's wrong with it?

Alex/Erik,
    I'm using xforms:group/@appearance='xxforms:internal' but I noticed that the relevancy only applies to the xforms:controls. Is it possible, when the group becomes irrelevant to apply display:none to all its child elements?

Thanks

Ryan

Ryan,

I think this is definitely an issue and we would like this to be fixed
sooner rather than later.

Note that some people think or thought that the fact that XHTML doesn't
allow to put anything between <tbody> and <tr> would prevent putting
XForms elements at that spot, but personally I think that XForms should
be allowed to do so and put <xforms:repeat> and <xforms:group> around
<tr> in particular.
