Writing process data back to HIFI forms

Ludwigg

I am trying to simulate a scenario where you can use a simple hifi form as package in your process, at some point allow a user/system to update a process variable and then map that back to the form to show the field "pre-populated" with the data when the next user opens the form in OpenOffice.

The mapping part is fine, and it works fine as long as there are no data in the variable field. However, the moment there is data in the field, the process mapping task hangs with looong error messages. I am not a JAVA expert, but it sees to me that the second set of error messages might contain a clue - it says something like "SAXParseException: content not allowed in prolog"

Any idea how to fix this?

Thanks

Ludwig

This error is related to the content of your xml having data before the XML starts that is not valid xml, Try adding a logging/debugging statement that outputs the XML you are trying to save out. Most likley there is a few characters that shouldn't be there right at the beginning.

Hallo David

Thank you very much for responding. I am trying to do something that I thought is very simple and should not cause any errors – apparently not so!

Let me say right upfront – I am not a programmer and I am a strong believer in the Documentum gospel that says “configure – don’t develop”!

I have a very simple hifi form – with 3 fields.

I open it in OpenOffice, complete two of the fields manually and save the file.

I then drop it in a directory on an ftp site, where the ftp initiate imports the file, link it to a folder and initiates a very simple process in which I map a view fields to the package/process variables and update the imported document’s metadata.

All I then want to do – is map the values from one field to the form to display the value in the form. When I check out the form, and manually complete it – it works fine.

If I map the values and test it with an “empty’ field it also works fine. However, the moment I update the process variable (from the DA) interface, I would have expected that the OpenOffice xml would simply accept the value that is passed via the data mapping – and display it. This is however where my process breaks.

Where do the “extra” values come from that causes it to be non-valid XML?

Can you briefly explain how I can add the loggin/debug statement – if you would be so kind as to have a look at it, it might solve my problem. This will be really helpful as I need to demo to a prospect on Wednesday and if I can show them how easy it is to update form data, that will be number 1. J

Thanks a lot.
