How can I synchronize external method completion with DTML method invocation? [and do I need to?] I found an unexpected bug in a Zope content management app I am developing: the actual publishing process invokes an External Method that uses urllib and ftplib to pull rendered documents from Zope and PUT them to a web server via FTP. One of the documents is a table of contents of the "current" documents, which is generated dynamically by a DTML method that looks at a property of each document in the folder. The last step in the publishing process is "archiving", a DTML method that clears the "current" property in all documents. What appeared to be happening was that the external method was still chugging along when it came time to grab the table of contents; meanwhile, the archive method had already cleared the "current" property, so there were no documents listed in the table of contents. First question: is my hypothesis likely? Are methods - in particular an external method - executed strictly sequentially (which is what I would have assumed) or is it possible that the DTML archive method could have completed before the prior external method did? Second question: if methods are _not_ executed synchronously, is there any way I can force them to be?
