I have a questionnaire that has 6 identification questions in the form of cascading combo boxes. The cover questions corresponds to the 6 levels of political-administrative organization of the country. In parentheses, the number of records for each category is shown.
When I test the questionnaire using the Designer Web Tester, everything works fine, I’m able to answer the questionnaire.
However, when I install the questionnaire in my PDS, the questionnaire behavior show these situations:
Sometimes it doesn’t display any records in the comboboxes for the cover questions. The comboboxes are empty. I have to upload the questionnaire again in the HQ server.
Sometimes it shows the following error message:
Thinking that it might be a behavior derived from the limited resources of a PDS, I decided to install the questionnaire in a more powerful server (4 CPUs, 16GB RAM) and I got the same results.
What might be the underlying cause of the problem?
