PHP dynamic content for form list field on tabbed panel

Question

I have been trying to use PHP dynamic content to populate a
form list field. Works fine on a regular page, but doesn't seem to
work (or works very erratically) if the form is on a tab of a Spry
tabbed panel. Erratically means (as I've observed) the values will
appear if the list field is the second on a tab but not the first.
Haven't tried three on a tab... Anyone know if this is supposed to
work?

Thank You !!! to both of you above.
Shant,
The scheme youv'e proposed makes sense and I had thought of the same before posting the question. I already did a little POC on it but then realised this works if I can use complete list of values of 1st Field to decide the value of 2nd and so forth. But I rather need to know which one among those was clicked. Moreover, my right side list is usually not null when page loads for the first time (bcoz Field name is a path exp).
Also, the real problem here is that, when I click on different values on the right side of multi-select(already selected values) of 1st Field, allowedValues and Derivation of 2nd should change. That GUI event is not capturable from whatever I've been able to read (onClick is not applicable for MultiSelect, and onChange doesn't serve my purpose, coz I need to know what value was clicked on).
The solution I thought and implemented was to take the right side of multi-select, into an extra (read redundant), single-select Field. And then have the 2nd multi-select depend on it via Derivation and allowedValues.
Having two redundant single-selects, isn't the most elegant solution but I can't think of anything better. Any thoughts ???
If I'm not really overlooking something MultiSelect class should have an extra Property exposed....
