Problem: variable disappears from Session after cfquery

Question

I have the following problem in my CFML script. I added a
variable MyVariable in Session variable. Then I call
<cfquery>. When the <cfquery> finishes, the variable
MyVariable does not exist in the Session!

Answer 1

In fact, name of the MyVariable was loginresult. The sequence
was approximately as the following:
<cfset Session["loginresult"] = 0>
<cfif Session["loginresult"] eq 0>
<cfquery ...>
<cfif Session["loginresult"] eq 0>
</cfif>
</cfquery>
</cfif>
The problem happened on SECOND line "<cfif
Session["loginresult"] eq 0>" - one that follows
<cfquery>. The line produces exception :
coldfusion.runtime.UndefinedElementException: Element
loginresult is undefined in a Java object of type class
coldfusion.runtime.MemorySessionScope referenced as
What is most misterious, I have teh same CFM code on two
computers (ColdFusion MX7 on both). One of them the code works OK;
on other it causes the problem I described.
