This is a thread from a discussion I had on the cfguru list. In this
last post from Kevin I realized my issue might not be CF in general
but OpenBD. Thoughts...

Derrick,
This works for me, so not sure if I'm misunderstanding the issue.
cfthreadtest.cfm
<cfset form.message = "I exist in the page's variables scope.">
<cfthread action="run" name="t1" myvar="#form#">
<cfsavecontent variable="threadattributes">
<cfdump var="#attributes#">
</cfsavecontent>
<cffile action="WRITE" file="#expandpath
("threadattributes.html")#" output="#threadattributes#"
addnewline="No">
<cf_threadcustomtag anothervar="#attributes.myvar#">
</cfthread>
Then in threadcustomtag.cfm:
<cfsavecontent variable="customtagattributes">
<cfdump var="#attributes#">
</cfsavecontent>
<cffile action="WRITE" file="#expandpath("customtagttributes.html")
#" output="#customtagattributes#" addnewline="No">

Thanks Kevin.
My thread actually is setting variables that I want to pass to the
custom tag. So in my thread I have this <cf_tag name=var1
Action=var2/>. However if I do a dump of the attributes within the
custom tag that struct is blank. Am I missing some crucial part.

You need to pass any 'outside' values into the thread as attributes.
<cfthread action="run" name="thread1" theform="#form#">
Then the struct, theform will be available within the thread, and
should be passed to the custom tag. The issue is the unique scoping
of cfthread; look up thread scopes in the docs for cfthread.
HTH,
Kevin

Subject: CFGURU: <cfthread> and Custom Tag
Folks,
This may be a simple situation/solution, but I have an app with the
following setup:
App generates <cfhttp> request to a URL and passes in formFields
The <cfhttp>'d page has its code wrapped inside a <cfthread> block.
Inside that block is also a custom tag.
When I execute the code within this page via the <cfhttp> call, the
attributes struct that is passed to the custom tag is blank.
However if I remove the <cfthread> block from around my code the
page does exactly what I want. Is there something about <cfthread>
and custom tags that I'm missing?
Sorry if this is an elementary question.
Thanks,
Derrick
