Why illustrator allowed pathItem store error msg?

So this happen, I cycle through my artwork, compare their typename ono by one, and my script keep crushing.

Turns out there is often one or two pathItem's object tree property completely lose their mind.

No property, but error msg like this image, and this happens so often.

Correct answer zertle

I have run into that same error too.  Unfortunately I still don't know what causes it.  Some ways to fix the problem that I've found are to select all, cut, and paste then try running the script again. This can be automated:

var done = false;
var firstTry = false;
while( !done ) {
  try {
    if( !firstTry ) {
       app.activeDocument.selectObjectsOnActiveArtboard();
       app.cut();
       app.paste();
    }
  
    /* CODE TO PROCESS GROUPS */
     
    done = true;
  }
  catch(err) {
    firstTry = false;
  }
}

This would all be inside of your function.  You could also add code to auto quit after 5 or so tries, just add a 'count' variable.

Other fixes I have found are closing and reopening the file or restarting Illustrator.  Sorry I don't have a better answer.

Can you please post a working piece of your code that an Adobe person can help work with and debug?

not sure why you used -1 in the for loop

try

for(i=0; i<targetGroup.pageItems.length; i++){

Hi, thanks for reply, your code is same as mine

  • Mine

     for(i=0; i<=targetGroup.pageItems.length - 1; i++){

  • Yours

     for(i=0; i<targetGroup.pageItems.length; i++){

both run the same times
