I think that in most cases, accessing the form vars in a component ruins the
separation of business and display logic . . . which may be OK depending on
how much of a purist you are.
I think the better solution is to name all of the CFARGUMENTs the same as
your form inputs, then use the ARGUMENTCOLLECTION attribute of CFINVOKE to
pass in the variables. This is straight from the docs:
Passing parameters in the argumentCollection attribute
If you save attributes to a structure, you can pass the structure
directly using the cfinvoke tag's argumentCollection attribute. This
technique is useful if an existing structure or scope (such as the
Forms scope) contains values that you want to pass to a CFC as parameters,
and for using conditional or looping code to create parameters.
When you pass an argumentCollection structure, each structure key is
the name of a parameter inside the structure.
The following example passes the Form scope to the addUser method of
the UserDataCFC. In the method, each form field name is a parameter
name. Then the method can use the contents of the form fields to add a user
to a database.
<cfinvoke component="UserDataCFC" method="addUser"
argumentCollection="#Form#">
Hope this helps,

Are you submitting the form directly to a CFC? If so, why not just
access each form variable individually in the CFC? Why do they need to
be in the arguments scope rather than the form scope?
