Negative sign for 0.00 disappear after upgrade



User has upgraded the UAT system from Pega 7.1.8 to Pega 7.2.2. and they noticed that in a screen with a numeric field input initialized to "-0.00" deliberately, when the user positions the cursor inside the field, on Pega 7.1.8, the negative sign will appear to remind the user that the field only accepts negative amount.

On Pega 7.2.2, the negative sign disappear, hence the visual prompt for negative amount is lost.

Error Messages

Not Applicable

Steps to Reproduce

1. Add a decimal field that is initialized to -0.00.
2. Run the usecase in Pega 7.2.2. The "-" sign disappears.

Root Cause

This issue is seen only when user gives a minus sign for zero.

In the Out-of-the-box (OOTB) logic, Pega converts the string value given by user to a number.

When property value is given as -0.00,since -0.00 is not a valid number and 0.00 is valid, Pega displays 0.00.

If a valid negative number say -1.23 is entered by the user,it is shown properly. Minus sign will not truncated.

In Pega 7.1.8, -0.00 is shown as -0.00 because of a bug which got fixed in later release of the product.


Perform the following local-change:

Add an event focus to the text input,configure runscript action and specify a function "SetInputValue" and pass event object to it.

In userworkform, add the following function code:

function sampleFunc(event){
var target =;
var value = target.value;
if(value == 0.00){
target.value = "-"+"0.00";
