Spotfire crashes when trying to Remove Page using Ironpython

[Lloyd Plum]

Trying to execute the following code:

for page in Document.Pages:

if page.Title == pageName:

Document.Pages.Remove(page)

Without fail, this results in the program crashing. If I execute within the Ironpython scripting window, I get the following error (followed by a crash when I exit the scripting window):

System.InvalidOperationException: Attempt to start ReadTransaction in state 'Detached'.

Version is 6.5.3

You should upgrade to latest versions as it does not crash in latest versions and also there is an option to execute script in transaction which is not present in 6.5 due to which it crashes as the page you might be deleting on the same page you might have your script in text area
