[CS3 JS] event crashes InDesign

Question

Scripting ladies and gentlemen,
I'm working on this event script that searches for linked PDF files and
lets the user copy/relink them. Using the afterOpen eventListener however
crashes InDesign no matter what I do. This is also the case with
beforeClose. It appears that my function cnvrtPDFlnk is causing the crash
(I'm able to alert succesfully with the afterOpen event if I //-comment
the cnvrtPDFLnk(myDocument)).
Do one of you scripting gurues have a tip?
#targetengine "session"
main();
function main() {
   app.addEventListener("afterOpen", myEventFunction, false);
function myEventFunction(myEvent) {
   var myDocument = myEvent.parent;
   var label = docLabel(myDocument, "PDFCheck");
   if(label) {
      //myEvent.stopPropagation();
      //myEvent.preventDefault();
      exit();
   else {
      cnvrtPDFLnk(myDocument);
function docLabel(myDocument, key) {
   var hasLabel = (eval(myDocument.extractLabel(key))?true:false);
   return hasLabel;
function cnvrtPDFLnk(myDocument) {
   var graphics = myDocument.allGraphics;
   var link; var linkExt; var linkType; var linkPath; var linkPageRef; var myConfirm; var myFolder; var myFile; var myOrgPath;
   var myLinkObjects = [];
   for (var i = 0; i < graphics.length; i++) {        
      link = graphics[i].itemLink;
      linkExt = link.filePath.split('.').pop().toLowerCase(); 
      linkType = link.linkType.toLowerCase();       
      if (linkExt == 'pdf' || linkType.match('pdf') != null) {
         link.show();
         if(myConfirm= confirm(link.name+"\nDo you want to convert this link?")?myLinkObjects.push(link):alert("Link skipped!\n"+link.name));
   if (myLinkObjects.length > 0) {
      myFolder = Folder.selectDialog("Point me to a hotfolder..");
      copyLink(myLinkObjects, myFolder); // run copyLink function - copies links according to myfolder
      if(myConfirm = confirm("Do you want to relink now?")) {
         reLink(myLinkObjects); // run reLink function - relinks according to myFile dialogue
         app.menuActions.item("Fit Page in Window").invoke();
         app.menuActions.item("First Page").invoke();    
   myDocument.insertLabel("PDFCheck", "true");
   }// no links
}// end cnvrtPDFLnk

Hi Rasmus,
Here is an example of scripted plug-in — very simple yet useful for me.
Its goal is to check color settings in InDesign and Photoshop after a document opens. We use two profiles at work: one for the main part of our magazine and another profile for its cover and the inset for another magazine. Sometimes, although rarely, we forget to switch on the correct setting.
That's where the plug-in comes to the aid. After a document opens it checks if the file name contains certain characters – e.g. if file name starts with "Obl_" that means that this is a cover and the script checks the color settings, if they are not correct it gives warning.
Here is short description of how to do it:
Create a new scripted plug-in project from APIDTemplate.indd file.
Open APID panel
Enter 'docLoaded' into Event Filter field and press Enter
Here is the script that does the job (the script file is generated in the same folder as indd-file):
if (theItem.eventCode == "docLoaded") {
   var gKasmyDoc = app.activeDocument;
   var gKasDocumentName = app.activeDocument.name;
   KasCheckProfile();
   KasinfoFromPS();
function KasCheckProfile(){
   var myIssueNumber = parseInt(gKasDocumentName.substr(2, 3));
   if (gKasDocumentName.substr(0, 2) == "Q_" && myIssueNumber >= 730 && myIssueNumber <= 999 && gKasDocumentName.match("_Vshivka") == null){
      if (app.colorSettings.workingSpaceCMYK != "ISO Web Coated"){
         alert("Внимание! Для газеты должен использоваться провиль \"ISO Web Coated\", а установлен. — " + app.colorSettings.workingSpaceCMYK);
   if (gKasDocumentName.substr(0, 2) == "Q_" && myIssueNumber >= 730 && myIssueNumber <= 999 && gKasDocumentName.match("_Vshivka") != null){
      if (app.colorSettings.workingSpaceCMYK != "ImationMatchprn175lpi_avr.icc          "){
         alert("Внимание! Для вшивки должен использоваться провиль \"ImationMatchprn175lpi_avr.icc\", а установлен. — " + app.colorSettings.workingSpaceCMYK);
   else if (gKasDocumentName.substr(0, 4) == "Obl_"){
      if (app.colorSettings.workingSpaceCMYK != "ImationMatchprn175lpi_avr.icc          "){
//         alert("Внимание! Для обложки должен использоваться провиль \"ImationMatchprn175lpi_avr.icc\", а установлен. — " + app.colorSettings.workingSpaceCMYK);
         if (confirm("Внимание! Для обложки должен использоваться провиль \"ImationMatchprn175lpi_avr.icc\", а установлен. — " + app.colorSettings.workingSpaceCMYK)) {
            app.colorSettings.cmsSettings = "Listovaya Mashina";
function KasinfoFromPS() {
   var bt = new BridgeTalk;
   bt.target = "photoshop";
   bt.body = "app.colorSettings;"
   bt.onResult = function(resObj) {
      var myResult = resObj.body;
      KascheckPsColorSettings(myResult);
   bt.send();
function KascheckPsColorSettings(myColorSettings){
   var myIssueNumber = parseInt(gKasDocumentName.substr(2, 3));
   if (gKasDocumentName.substr(0, 2) == "Q_" && myIssueNumber >= 730 && myIssueNumber <= 999 && gKasDocumentName.match("_Vshivka") == null){
      if (myColorSettings != "ISO Web Coated"){
         alert("Внимание в Photoshop! Для газеты должен использоваться провиль \"ISO Web Coated\", а установлен. — \"" + myColorSettings + "\"");
   if (gKasDocumentName.substr(0, 2) == "Q_" && myIssueNumber >= 730 && myIssueNumber <= 999 && gKasDocumentName.match("_Vshivka") != null){
      if (myColorSettings != "Listovaya Mashina"){
         alert("Внимание в Photoshop! Для вшивки должен использоваться провиль \"ImationMatchprn175lpi_avr.icc\", а установлен. — \"" + myColorSettings + "\"");
   else if (gKasDocumentName.substr(0, 4) == "Obl_"){
      if (myColorSettings != "Listovaya Mashina"){
         alert("Внимание в Photoshop! Для обложки должен использоваться провиль \"ImationMatchprn175lpi_avr.icc\", а установлен. — \"" + myColorSettings + "\"");
You can put your own stuff into the script:
if (theItem.eventCode == "docLoaded") {
// do your stuff here
And finally generate the plug-in.
