Thread: ProductLink: What am I doing wrong?

Hi, I am desperate and feeling myself the dumbest human being in the world...



I am trying to do doing things the way MultiStore manual tells me to do (http://manual.aspdotnetstorefront.co...ackages.aspx):

<xsl:variable name="productid"><xsl:value-of select="SFProductId" disable-output-escaping="yes" /></xsl:variable>
<xsl:variable name="mylink"><xsl:value-of select="aspdnsf:ProductLink($productid, '', 0)" disable-output-escaping="yes"/></xsl:variable>
<a href="{$mylink}"><xsl:value-of select="Name" disable-output-escaping="yes" /></a>

But it doesn't work, instead it crashes my XMLPackage and clearly the problem is in the piece in red, because when I remove it the XMLPackage doesn't crashes.

When it crashes it asks me to look at error log. Looking at the error log I have:

Page URL:/Web/t-custom-remaining-parts.aspx

What am I doing wrong????

given the error message says can you show your opening xsl:stylesheet tag? I think that is where your issue is. Also are you trying to do a xmlPackage accessible function?

mmcgeachy, thank you very much for your post!

It gave me a clear clue about what the problem could be. Actually I was just using the very same old XMLPackages, and my stylesheet tag was:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:aspdnsf="http://www.DNSF2.com">

Anyway, when I changed it to:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"xmlns:aspdnsf="urn:aspdnsf">

The crash problem is gone, BUT it is still not working correctly: now the function is returning me a void link (no link).

I am sure that the productid I am passing through is correct. The only issue I can see on my declaration is that I am passing a void product name, however in the manual they say that I can do that and that the function will figure out the product name, so I don't think that it really be the cause.

Any idea?

PS: In the manual there is a note about ProductLink function that says "NOTE: This function is for backward compatibility with Parser functions only and should not be used in XmlPackage transforms because it outputs invalid XML when using the IncludeATag." Question is: since this is considered a deprecated function, what would be the one to be used in place of?

Are you sure the product id is right? SFProductId isn't the normal name for the productid column. Since you could be running a custom query it hard to say for certain but it sounds off to me. To check set the debug to true and you can see for certain. The .xml part is mostly where you should look.

As for the deprecated thing in the documentation I don't really know to be honest. There are a few more overloads options but that shouldn't matter.

From another XML package provided in the source:

Code:

<xsl:value-of select="aspdnsf:EntityLink(EntityID, SEName, $EntityName, 0, '')" />
