Re: [Xsltforms-support] Unsupported mediatype 'text/html' for instance #myinstance

[<bc...@sh...>]

Hello

I think I have sorted this.

Firstly, I had contributed to the problem because I had not added the
xforms xmlns prefix to the resource element in the submission.

Secondly, I have realised (through debug and further reading etc) that the
resource element's 'value' attribute has to be an xpath (or an xpath
function); a plain text string (to a resource) as I had, will not work.

Therefore this works now:

<xf:submission id="mysubmission" method="get" serialization="none"
mode="synchronized" replace="instance" instance="myinstance">

    <xf:resource value="concat('/rest/db/data/','myxmldoc.xml')" />
</xf:submission>

But my original:

<xf:submission id="mysubmission" method="get" serialization="none"
mode="synchronized" replace="instance" instance="myinstance">

    <xf:resource value="/rest/db/data/myxmldoc.xml" />
</xf:submission>

will not work, as the @value is not an xpath or a function.

That's how I figure it anyway :-)
Thank you


Marked as solved.
