Hi,
I am trying to use to add nil="true" in my destination instance but it returns with
"Object reference not set to an instance of object" error.
Thanks in advance,
Brian

Update from OP:
The XSLT being used is of form:

XML

<xsl:template name="SetNilValue" xmlns:xsl="#unknown">
       <xsl:param name="IsNil">
               <xsl:choose>
                   <xsl:when test="$IsNil = true">
                        <xsl:attribute name="xsi:nil">true</xsl:attribute>
                   </xsl:when>
               </xsl:choose>
</xsl:param></xsl:template>

Solution 1

Well, the error simple means you are trying to use a property of an object that is null.

Since you have not shared the code, difficult to specify it where exactly but a simple use of VS DEBUGGER can point you to correct place and you can handle the same.

Sandeep,
Thanks for your reply, I tested with other simple schema and it works but when I tried with real schema for my project it returns that error. But unfortunately I can not share my schema here. I will look into more.

Thanks,

Ok.

What you need is to look at the line from where the error is thrown. (Stack Trace must be showing it). Just put a DEBUGGER there and then look at the objects. Surely one of them would be null and you must be trying to get any property of that null object.

Sandeep,
I am trying different approach to have my own script functoid to add xsi:nil=ture based on input.
so I have this code but it seems not working. I do not see the element at all.
I am using Inline XSLT Call Template with one input, if the input element has xsi:nil="ture" then I will add this attribute in the destination element.

*Refer the XSLT in question. (Moved there)

Thanks,

Sandeep,
I copid my code but it removed all tags, is there easier way to copy code here?
Thanks,

Sandeep Mewara 31-Mar-11 13:02pm

I just edited your question with your code that you tried to put here.

In case needed, edit your question and update it with some snppets that you can share across.
BTW, based on what you say, sounds like an issue in XSL?

CannonD 31-Mar-11 13:07pm

Yes, I am trying to solve it using xsl but not sure how to make conditional xsl.

thanks,

Sandeep Mewara 31-Mar-11 13:13pm

You should have tagged it correctly to get proper audience to look at it. I would suggest you to post the XSL issue that you have as a separate question and try to put as much info with the stress on 'conditional XSL' thing. See what you get back.

Solution 2

Its difficult to pinpoint since I am not seeing your solution. Anyway, Check Application section on the event viewer of your Biztalk Admin Console. The error is usually labeled with the word Biztalk or XLANG. From there, you will be able to determine which orchestration has errored.
