1: Introduction

Known issues

➤

Scripts that create, save, and close many Illustrator files should periodically quit and relaunch

Illustrator. The recommended maximum number of files to process before quitting and relaunching

Illustrator is:

➣

Windows

500 files

➣

Mac OS

1000 files

For more information on quitting and relaunching Illustrator, see

“

Launching and activating

Illustrator

and

Quitting Illustrator

” on page 26

➤

The “An Illustrator error occurred: 1346458189 (“PARM”)” alert may be popped when badly written

scripts are repeatedly run in Illustrator from the ESTK.

Scripters need to be very careful about variable initialization and namespace conflict when pushing a

batch of Illustrator scripts repeatedly for execution in Illustrator via the ESTK in one Illustrator session.

Each script run is executed within the same persistent ExtendScript engine within Illustrator.

The ESTK debugger uses BridgeTalk to communicate with Illustrator. A single global, persistent,

ExtendScript engine inside Illustrator handles all BridgeTalk communications. The net effect is that the

state of the ExtendScript engine is cumulative to all scripts that ran previously. Issues with script code

that may cause this problem are:

➣

Reading uninitialized variables.

➣

Global namespace conflicts, such as when two globals from different scripts are clobbering each

other.
