DocumentList GetNthDocument fail

[Rick E Johnson]

Getting a list of all open documents without actually displaying them usually works well, although sometimes, especially after a Save As (kAISaveAsCommandPostNotifierStr), it crashes. Here's the code, which resides in a for loop. DocCount has been correctly retrieved (3) and document 0 gets handled correctly. When it comes to item 1, however, it works perfectly when just opening or closing files, but crashes with an EXC_BAD_ACCESS error in the compiler (Xcode 8 with Mac CC 2017) at Activate on item 1 after a Save As. The value of "error" returned from AI is always 0.

  AIErr error = kNoErr;

  ai::UnicodeString fullPathString;

  AIDocumentHandle doc = NULL;

  for (uint32_t i = 0; i < (docCount); i++) {

  error = sAIDocumentList->GetNthDocument(&doc, i);

  error = sAIDocumentList->Activate(doc, false); // error = 0 here but crashes if i>0 and just did Save As

  ai::FilePath filep;

  error = sAIDocument->GetDocumentFileSpecification(filep);

  error = sAIFilePath->GetFullPath(filep, true, fullPathString);

  std::string sFullPath = fullPathString.as_UTF8();

  if (sFullPath != "/") this->vOpenFiles.push_back(sFullPath); // save in string vector

  }

Last, it activates what was/is the current doc. Am I overlooking something I should have included here?

TIA -- Rick

Sounds like the sort of thing that happens when you are not in the correct plugin context, but if the code is called in response to a notifier message the context should be set correctly.

What is the value of doc when it crashes, is it NULL?

You could try the old "set a zero timer" trick so your code is called after Illustrator has finished whatever it was doing.

Thank you (again) LeoTaro! The zero timer trick worked. Or at least I can't make it crash again. All the best, my friend -- Rick
