The component will be blind to the table(s) of the host.
So, the solution that I think (i haven't coded this part yet) will work is:
(Component Method)
// Export_All
//$1 - pointer - to a pointer array where each element
// of the array points to a Host table to be exported
//$2 - text -

You don’t have to generate an error - you could just call OB IS DEFINED
instead, then branch your code appropriately without generating an error stack.
Chip,
Of course if you want access to a specific table you can just do this:
C_POINTER(<>TSK_TaskTable_ptr;<>TSK_ID_ptr;<>TSK_Name_ptr)
EXECUTE FORMULA("<>TSK_Name_ptr:=->[Task]")
EXECUTE FORMULA("<>TSK_ID_ptr:=->[Task]ID")
EXECUTE FORMULA("<>TSK_Name_ptr:=->[Task]Name")

Chip,
The technique that Dave Batton used in Foundation (and released publicly in
a couple of free components) went like this:
Start most methods with a call to the INIT method:
Eg.
//
// Project Method: Log_Init
// Initializes both

Thanks Jim.
So based on your post, I tried it with Select Document and as you note it works.
Then I changed the path name to use the Folder Separator constant even though
“:” (semi-colon) seemed to be working fine and voila, the code works.
Don’t know why but it works.

if the document is not correctly loaded, as others have speculated:
1. given this is Mac, could there be a hidden file extension?
2. Given no encoding is not specified, could it be saved in UTF-16?
Document to text doesn't update OK,
the only way to know that it worked is to check that the

IP variables once at at startup in a component method. One way to do this is to
have an “Component_Init” method
Just tried exactly that (I used select document and the Document variable to
get document).
It worked with no problem.
I tested on v16 OSX10.10.5
So it's either v14 problem or your settings.

I think I know how to do this.
The Export_All method will require a single parameter which (a pointer
to) is an array of pointers to the host tables to be exported.
Then the host can control the export by only sending those tables which
need to be exported
and the component will
How do you know PROCESS 4D TAGS is failing?
Have you confirmed that the process variable "tTemplate" actually contains your
template?
In other words, does “Document to text” successfully retrieve the template?
When the command “Document to text” encounters an error, the command fails
Chip,
No. But you can pass a pointer to a table and within the component build a
pointer array of the fields.

Is it possible to get access to host tables without a pointer to the
table?
One of the methods I wold like to "componetize" is a routine that
exports ALL the data in the system.
I know I can expose a method which exports a single table (with a
pointer to the host table), but i would like to be
do I need to initialize the component's IP, or process variables in

Most probably the problem comes from 'Set field/table titles'…
What source is used to set virtual names?

I stumbled on this a few weeks ago. I think I tracked it down to a
