Hi James, There are several reasons why doing this seems error-prone from a workflow perspective, but I'll trust that you've thought things through.
I believe you could do the following: * use the logic module to write a rule (in groovy) which returns the highest-so-far obs for any patient for that concept. (You can do that with the ObsService.getObservations method, with mostRecentN=1 and sort="valueNumeric desc". Then add 1.) * Do a <lookup/> tag where you call that logic rule. * Do some javascript craziness to put that value from the lookup into an obs field. -Darius On Thu, Sep 15, 2011 at 10:06 AM, James Arbaugh <[email protected]>wrote: > When designing an HTML form, or xForm, is there a way to pre-populate the > field in the form with the next consecutive number for that observation > type?
