Alex Mayer commented on MYFACES-224:
------------------------------------

I wonder, that you found everyting working.
I added a message to my sort-class which is printed out everytime the sort-=
method is called.
So with above code the sort-method is just called once. I changed the prese=
rveDataModel to false which did not change a thing. The sort method is only=
 called once regardless which value is applied to preserveDataModel.

The x:columns-tag adds to my opinion to every column the same id. That is w=
hy EVERY column looks the same except the applied value for the outputText =
like this:

<th><input type=3D"checkbox" name=3D"_id0:data:_id3:0:_id5" /><a href=3D"#"=
 onclick=3D"clear__5Fid0();document.forms['_id0'].elements['_id0:_link_hidd=
en_'].value=3D'_id0:data:_id3:0:_id6';if(document.forms['_id0'].onsubmit){d=
ocument.forms['_id0'].onsubmit();}document.forms['_id0'].submit();return fa=
lse;" id=3D"_id0:data:_id3:0:_id6">header1&#x2191;</a></th><th><input type=
=3D"checkbox" name=3D"_id0:data:_id3:0:_id5" /><a href=3D"#" onclick=3D"cle=
ar__5Fid0();document.forms['_id0'].elements['_id0:_link_hidden_'].value=3D'=
_id0:data:_id3:0:_id6';if(document.forms['_id0'].onsubmit){document.forms['=
_id0'].onsubmit();}document.forms['_id0'].submit();return false;" id=3D"_id=
0:data:_id3:0:_id6">header2</a></th><th><input type=3D"checkbox" name=3D"_i=
d0:data:_id3:0:_id5" /><a href=3D"#" onclick=3D"clear__5Fid0();document.for=
ms['_id0'].elements['_id0:_link_hidden_'].value=3D'_id0:data:_id3:0:_id6';i=
f(document.forms['_id0'].onsubmit){document.forms['_id0'].onsubmit();}docum=
ent.forms['_id0'].submit();return false;" id=3D"_id0:data:_id3:0:_id6">head=
er3</a></th>


The point is, that when I click on a commandSortHeader-Link in the table, n=
othing happens. The sort-method is not called. And the page isn't rendered =
again either. Internet Explorer is announcing a javascript error whereas fi=
refox doesn't (but I don't have the js-debugger console in firefox installe=
d)

>                     </x:columns>

> in case I use a component-binding for the x:dataTable to generate a corre=
sponding table in a bean, everything works fine.             =20
> I believe this is, because the x:columns-tag assigns to every childcompon=
ent of type commandSortHeader the same id.
