<DIV>After examining the profiler I see that the main time is taken with the following:</DIV>
<DIV> </DIV>
<DIV><FONT face="Courier New">instance('report-transformed')/body/table/tr[not(td[3] = preceding-sibling::tr/td[3]) and not(td[3]='')]</FONT></DIV>
<DIV><FONT face="Courier New"></FONT> </DIV>
<DIV><FONT face="Courier New">This is my way of populating a second select box with unique values from an xhtml file that is loaded into my form, and I suspect (but don't know) that changing the selected value in my first select box is triggering a refresh of the whole form. Is this the case? Can it be prevented so that it only happens when I make a submission on the changed select box value?</FONT></DIV>
