Hello all, I originally sent this one just to the zope@zope.org list, but I just saw a bug report similar to this about 2.5.b2 on the Zope collector at http://collector.zope.org/Zope/77, so I figured I'd also submit it to you. I'm running 2.5.0-src (see traceback below). I have a problem regarding allowing the import of extra modules. I've found various examples (like the "Allowing Import of Modules" in the Zope online help) and a mailing list item entitled "Import Libraries into Python Script" (http://lists.zope.org/pipermail/zope-dev/2001-February/009531.html), but these aren't helping me. I'm still getting this error. I'm trying to use the Reportlab toolkit from within a Zope script (NOT an external method). I DON'T want to just import the whole Reportlab toolkit, because within that toolkit there are sys and os sections with what appear to contain very dangerous items. Therefore, I'm following more along the lines of the help in the Zope online help. I created a folder called MyScriptModules in $ZOPE/lib/python/Products/. The __init__.py file therein looks like this: -------------contents of __init__.py------------------------------------- from Products.PythonScripts.Utility import allow_module, allow_class from AccessControl import ModuleSecurityInfo, ClassSecurityInfo from Globals import InitializeClass from reportlab import platypus from reportlab.lib import colors, enums, pagesizes, styles, units from reportlab.pdfgen.canvas import Canvas allow_class(Canvas) allow_class(platypus) allow_class(colors) allow_class(enums) allow_class(pagesizes) allow_class(styles) allow_class(units) ModuleSecurityInfo('reportlab').declarePublic('platypus') ModuleSecurityInfo('reportlab.lib').declarePublic('colors','enums','pagesize s',' styles','units') ModuleSecurityInfo('reportlab.pdfgen.canvas').declarePublic('Canvas') -------------end __init__.py contents--------------------------------- I only wanted to import the bare essentials of my current program and some other classes that looked harmless but useful (like colors, enums, etc). I first started with ReportLab by creating a shell-based python script, which ran perfectly and created my PDF file. Now I'm porting it to Zope and I'm getting errors. Here's a curtailed example of the script. This short example creates the same error I'm getting in the full version of the script: ------------begin sample problem script----------------------------- #_______DO ALL THE IMPORTS__________________________________________________ from reportlab import platypus from reportlab.lib import styles, units, pagesizes from reportlab.pdfgen.canvas import Canvas import string #_______END IMPORTS SECTION_________________________________________________ #_______SET UP GLOBAL VARIABLES_____________________________________________ PAGE_WIDTH = pagesizes.letter[0] PAGE_HEIGHT = pagesizes.letter[1] txt_styles = styles.getSampleStyleSheet() styleTITLE = txt_styles['Heading1'] #_______END GLOBAL VARIABLES________________________________________________ return "I didn't crash" -----------------------end sample problem script--------------------------- When I try to test it Zope tries to make me log in again, I do so, and it asks me to log in repeatedly. If I finally click "Cancel", it gives me this: ------------------begin error condition experienced--------------------------- Zope Error Zope has encountered an error while publishing this resource.

However, if I comment out the line "styleTITLE = txt_styles['Heading1']" it does complete successfully. That means that the "pagesizes" stuff did import properly, because the PAGE_HEIGHT and PAGE_WIDTH get calculated properly (I can even return those successfully). Sorry for the long email, but I wanted to give a complete description of what I'm up against here. I suspect there's some problem in my __init__.py that's preventing me from accessing subobjects of what I've imported, but I'm not sure how to resolve it.
