Export PDF Workflow with Applescript and CS3

Question

Hello,
I am setting up some PDF workflow with Applescript.
On a given moment, as my script runs and after getting some user-input answers to questions in some dialogs, my script tells InDesign CS3 to open the Export Adobe PDF window for the current document. I copied and pasted that small part of the script:
tell application "Adobe InDesign CS3"
tell document 1
export format PDF type to "Macintosh_HD:Test01.pdf" using "somePreset" with showing options
end tell
end tell
When you run this small part of my Applescript, InDesign opens the Export Adobe PDF window (as expected) waiting for me to click on "Export". That is exactly what I want, since the user is given here a last opportunity to change some values (for example page range, or spreads). When all is set, the user can click on Export to close the dialog and finish the script.
Problem: I was hoping that the Adobe PDF Preset "somePreset" would be selected in the first pull-down menu of the Export Adobe PDF window when this window is opened by the script. Unfortunately the last used preset is always selected by default. Anyone suggestions or help?
Kind regards,
Bertus Bolknak.

Answer 1

My operators enter the page range and filename into a dialog box. Then I set those in the script. I use the Press Quality preset to start with and then set the changes I want into a export variable. I set things like bleed, marks, page range, etc.
Here is an example:
set theProps to properties of PDF export preset "[Press Quality]"
try
delete PDF export preset "Schmidt PDF"
end try
set theStyle to {name:"Schmidt PDF", acrobat compatibility:acrobat 7, bleed top:"0.125i", bleed bottom:"0.125i", bleed inside:"0.125i", bleed outside:"0.125i", page marks offset:"0.125i", include ICC profiles:Include None, effective PDF destination profile:use no profile, effective PDF X profile:"No Color Conversion"} & theProps
make PDF export preset with properties theStyle
set properties of PDF export preferences to theStyle
set color bitmap sampling of PDF export preferences to none
set grayscale bitmap sampling of PDF export preferences to none
set page range of PDF export preferences to (item i of myPageList) as string
export document 1 format PDF type to (PrinergyFolder & myJobNumFinal & "_" & VerCode & ".pdf") as Unicode text without showing options
I am also doing this in Quark.
