I have a XronDTMLMethod with the following body: ---- <dtml-let zoffice="superValues(['ZOffice Converter'])[0]"> <dtml-call "zoffice.getConverterByName('AsyncZlaveClient').fireNextConversion(_)"> </dtml-let> ---- So, it finds the nearest 'ZOffice Converter' instance (in the acquisition chain), names it 'zoffice', then attempts to do the call in the middle line. My ZOffice class has the following method defined: ---- def getConverterByName(self, converterName): """ """ return self._pluginConverters[converterName].__of__(self) ---- self._pluginConverters is a class level dictionary with keys of converter names and values of converter instances. The converter instances inherit from Acquisition.Implicit. However, when I 'Trigger' the XronDTMLMethod, I get the following error: ---- Traceback (most recent call last): File "D:\Zlave\zope251\lib\python\Products\Xron\XronDTMLMethod.py", line 141, in trigger REQUEST=REQUEST, RESPONSE=RESPONSE, kw=kw) File "D:\Zlave\zope251\lib\python\OFS\DTMLMethod.py", line 127, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_String.py", line 473, in __call__ try: result = render_blocks(self._v_blocks, md) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_Let.py", line 76, in render return render_blocks(self.section, md) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_Util.py", line 159, in eval return eval(code, d) File "<string>", line 2, in f File "D:\Zlave\zope251\lib\python\AccessControl\DTML.py", line 29, in guarded_getattr return guarded_getattr(*args) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeGuards.py", line 58, in guarded_getattr return inst.aq_acquire(name, aq_validate, validate) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeGuards.py", line 40, in aq_validate return validate(inst, obj, name, v) File "D:\Zlave\zope251\lib\python\AccessControl\SecurityManager.py", line 83, in validate self._context) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeSecurityPolicy.py", line 145, in validate raise Unauthorized(name, value) Unauthorized: You are not allowed to access fireNextConversion in this context ---- So, my question; why can't I call this method of my converter object? cheers, tim
