Description
When using a Client Script to try to set a Date/Time field to empty in Tablet Mode, the value returned will be 1969-12-31 19:00:00.
When leaving the Date/Time field blank, the system is inputting a negative value to calculate the unexpected date. No error message is thrown.
Steps to Reproduce
Activate 'Tablet Device Support - iPad with iOS 6+' plugin
1) Go to System Definition > Tables
2) Search for Incident and open
3) Under Column Tab, click New
4) Set the following:
Type: Date/Time
Column label: Tablet Date
Column name u_tablet_date
Leave everything else default
5) Save
6) Go to Incident > Create New
7) Right-click header > Configure > Form Layout
8) 'Under Form view and section' > Section, scroll down to New…
9) Section caption: Tablet Test
10) Click 'OK'
11) In the left 'Available' column, find 'Tablet Date' and add to the 'Selected' column
12) Click 'Save'
13) Go to System Definition > Client Scripts
14) Click 'New'
15) Set the following (I have also attached the client script sys_script_client_71803cb0747022004e829bd26ebc8fba.xml):
Name: Tablet test
Table: Incident[incident]
UI Type: Both
Type: onLoad
Active: check
Global: check
Script:
function onLoad() {
alert(g_form.getValue('u_tablet_date'));
g_form.setValue('u_tablet_date','');
alert(g_form.getValue('u_tablet_date'));
}
16) Save
17) Go to Tablet Development > Switch to Tablet Mode
18) Go to Incident > Create New
19) Notice the alert set to 1969-12-31 19:00:00 - Tablet Date will show 12/31/1969 7:00 PM. The Date/Time field should instead be left to empty with no value.
