Orbeon Datatable - <xf:input .... > - Error

This post was updated on .

There seems to be a bug, when I edit "samples/datatable-ng.xhtml and change <xf:output> statements to <xf:input> statements, I get the following error:

XPath syntax error at char 12 in {$nodeset[1]/}:
Unexpected token "<eof>" in path expression

Please see attached.

This is strange because all I’m changing is the xf:output tag. However, this doesn’t see to happen with all the tags. If I change the <xf:output ref="CCC"/> tag, it works fine. But if I change the <xf:output ref="AAA"/> tag, I get the previous error message.

My understanding from Eric, who wrote the datatable, is that this will
work if you explicitly specify fr:sortKey [1] for the columns
containing anything besides xf:output.

Erik,

Thanks for the note. According to the documenation,

" fr:sortKey: define the XPath expression to be used as a sort key. When not specified, this key is derived from xforms:output controls found in the column."

As a result, if I don't explicitly specify a sort key, and I replace all the xf:output tags, then the code breaks because it can't find an xf:output tag.

A workaround was suggested by Phillip Cantin:

Try putting this:

<xf:output ref="AAA[false()]"/>

<xf:input ref="AAA"/>

Quick note: If you use the AAA[false()} approach, the sorting functionality will break.

I got around this by just hiding the output tag w/ css instead of using the "[false()]" approach.

ex:

<xf:output ref="AAA" style="display: none;" />
<xf:input ref="AAA"/>

Re: Out of Office AutoReply: Orbeon Datatable - <xf:input .... > - Error

Very useful because i need to define datatable, but WHERE put this code ?
Nowhere is said.
There is a lot of posts in forum and orbeon website, with lot of codes to use, but nowhere is said where write these codes.
