Problem updating payload on human task

Question

Hi,
I'm developing an form where the user has to fill a set of fields, this fields are stored in the task payload. What happens is that if I use the save action the payload is updated but the screen refreshes and you need to selected the task on the work list again. To resolve this issue I'm using the update function of the task data control, but it only allows me one update to the data in the payload, then if I change a field and update it, it's not stored. I'm looking for a way to replicate the save action but without closing the form.
Thanks.

Are you using ps2 (11.1.1.3)? There was an issue where initiator human task activities that had parameters that were complex types needed to have the Data Object initialized via a script activity, or the fields could not be edited in the task from.
There's an example of how to use the script in the SalesQuoteDemo. Basically you use the oraext:parseXML() function to create an initialized version of the Data Object and assign it to the Data Object in a script activity that's placed before the Initiator Human Activity. It can also be used to set defaults if needed. Here's a snippet of the expression from the SalesQuoteDemo.
oraext:parseXML('<ns1:QuoteRequest xmlns:ns1="http://www.mycompany.com/ns/salesquote"><ns1:Summary>....</ns1:Summary<ns1:QuoteRequestStatus/></ns1:QuoteRequest>')
