I need to upgrade to Umbraco v 4.7.2. Which procedure do i need to follow if i have the Contour package installed?

I have now got everything working in backoffice. I can create new forms and data sources and front-end forms are sending entries. All my original forms are still working and my data is still there.

My only problem is that i get an "Error parsing XSLT file:".

My XSLT uses the Contour xslt extension:

umbraco.contour:GetRecordsFromForm

This is used to parse data from the Contour XML and into a HTML table that i used front-end to display user entries.

It was working before the upgrade.

I tried to output the raw XML

<textarea><xsl:copy-of select="umbraco.contour:GetRecordsFromForm('3efa868e-39f0-4413-9958-464be958a84c')"/>textarea>

But could not save the XSLT file because of an error.

I saw that

xmlns:umbraco.contour="urn:umbraco.contour"

was missing in the header, so i wrote it into my XSLT file.

Then i got: 

Cannot find a script or an extension object associated with namespace 'urn:umbraco.contour'.

Problem fixed.

Just needed to add

 <ext assembly="Umbraco.Forms.Core" type="Umbraco.Forms.Library" alias="umbraco.contour"></ext>

to the xsltExtensions.config file.

When creating a new XSLT file now, the correct xmlns namespace will be added, at the top of the XSLT file automatically.

is working on a reply...
