OK, I found it. Tab order seems to be declared in XFA using the following syntax:
<traversal> <traverse ref="(SOME_OTHER_FIELD)[index] /> </traversal> Some other field (above) is the ID of the first field. Outside of the fields element depth is a traversal start point, also referencing a single unique field in the PDF/XFA document. After playing around with LiveCycle Designer a bit, it turns out that until you save the form that is open, the traversal info is not present and is only added if the default tab order is changed. I double checked this with the reference to XFA and found this: "Traversal order. An XFA template may be defined with a traversal order, which allows the user to tab from one field to the next." The specification is here: http://partners.adobe.com/public/developer/en/xml/xfa_spec_2_4.pdf To aster your other question Maruan, yes - there is a default tabbing order. This is described in terms of left to right and flowing vertically. THere is a complete description of the order described when multiple elements of the same sub-form contain children.
