Good morning mobile team and other interested parties!

I have been able to replicate this error using the latest version of the
Android mobile capture app and version 2.21 of DHIS2.

This is a real use case that needs to be resolved by the end of next week
if we are to use calculated indicators in the field.

Mobile teams are optionally taking some patient measurements during the
capture of an unregistered event … including weight and height. We want a
simple BMI indicator to display.

The two fields height and weight are of type ‘NUMBER’. If we don’t have any
program indicators on a simple test section, just weight and height, then
we can capture values



If we go and create a BMI program indicator and add it to the section … and
go back to the existing ‘encounter’ … a BMI field appears and displays the
correct value.


As SOON as you try to change one of the values (weight or height), the App
crashes. If it is a new encounter, and you try to add a value with a
decimal, it crashes.



It seems to be a problem with how the ‘expression’ is handled for NUMBERS
that include decimals (it doesn’t crash if you enter just integer weights
and heights into the fields, but in this case doesn’t show the correct BMI
value either).

The system information in the error report is:


Happy to provide a login if you want to troubleshoot the apparent bug. (I
tested this on a whole fresh server install yesterday just to be sure it
was repeatable).
