Hi,
If you are opening the same instance of the form then you could add some JavaScript code like;
var autoNumber = xfa.datasets.resolveNode("formState.autoNumber");
if (autoNumber == null)
{
// If our 'formState' dataset does not exist then create it with a value of zero.
var formStateXML = <formState><autoNumber>0</autoNumber></formState>;
var formState = xfa.datasets.createNode("dataGroup", "formState"); // Note the 'formState' in this line becomes the top node not the 'formState' in the XML
formState.loadXML(formStateXML.toXMLString());
xfa.datasets.nodes.append(formState);
}
else
{
// If our 'formState' dataset does exist then increment the autoNumber property.
autoNumber.value = (parseInt(autoNumber.value,10) + 1).toString(); // Can only assign strings to a dataValue object
}
This will create a customs dataset, called formState in this script, sort of like a custom data connection. Once this is setup then you can reference it in your field using
xfa.datasets.formState.autoNumber.value;
Here is an example, https://acrobat.com/#d=431ge6d-3J1-teEUE2EAiQ
Hope this helps
