[ZPT] TALESError

[Chris Meyers]

I am using python 2.1.2 with Zope 2.5 on a RedHat Linux Server, and I am getting the following error message when viewing a zpt page in a browser:

 Error Type: TALESError
 Error Value: exceptions.IOError on [Errno 5] Input/output error in '', at line 40, column 1

The prolem is that I don't get the error all the time. It will work most of the time, and then once in a while I will get that error. If I go back or forward in my browser and then come back to the page it displays fine. Specifically the page that I am getting this error on is a display of some data from a zsql query 30 records at a time with a next previous button at the top. While paging through the record set with the next previous button I will occasionally get the error. It doesn't consistantly happen for one chunck of data, i.e. one time through the record set I will click the next button to get to records 121-150 and I will get the error, then the next time I won't get the error until I reach records 271-300.

The line that the error is pointing to looks like this:

<div tal:repeat="item python:here.qrymgr(requestID)">

where qrymgr is a python script which builds the SELECT statement for the query, calls the zsql method and then returns the record set to the zpt.

Anyone have any thoughts?
Thanks
