[Zope] array module and pickleing ques

[Aseem Mohanty]

That seems to be the answer. However I tried Charlie's suggestions and 
made the data members as lists (not strings as he suggested, seemed to 
work equally well and I didnt have to switch back and forth between 
functions calls) instead of arrrays and only instantiated arrays where I 
needed to use them (only inside of functions) as local variables.

Well it doesnt work. Everytime that function (that has an array 
declaration inside) is called I get another UnpickleableError.
I am at my wit's end... how do I get around it or force it through...

any help would greatly appreciated.

one function that raises that error:
 
def _reverse_hex(self,s):
        x=array.array('c',s) ## causes the error .... no problems if I 
remove it
        for i in range(0,len(s),4):
            a=x[i]
            b=x[i+1]
            c=x[i+2]
            d=x[i+3]

            x[i]=c
            x[i+1]=d
            x[i+2]=a
            x[i+3]=b
        return x.tostring()

TIA
