How exactly delta.isFieldChanged() method works?

AN_10548594 — Fri, 10 Jan 2025 07:39:49 GMT

Hello team,

Could anybody explain the way these methods work?

var isFieldChanged = delta.isFieldChanged(myTextField);
var isFieldReallyChanged = delta.isFieldReallyChanged(myTextField);

They always return FALSE even if I edited myTextField. Why?

The idea is to use an own way of "item is edited" process calculation.

Using of "Significant Change Since Item Revision" field is not suitable for some reason.

Regards

Hello.

precondition is a PRE trigger.

isFieldChanged returns true if the field was touched; so any modification will result in 'true'

isFieldReallyChanged returns true only if the value was finally changed to be different than before; so changing value and changing back will result in 'false'

As an example, I used default Text field which of course is rich text and a FVA.

Initial value before change was 'Hi' and I changed it to 'Hello':

2025-01-13 11:15:00,359 DEBUG [mksis.IntegrityServer] DEBUG(5): Administrator[RMI Executor-thread-2]: Trigger "delta_set_REQ.js" - changed: true
2025-01-13 11:15:00,359 DEBUG [mksis.IntegrityServer] DEBUG(5): Administrator[RMI Executor-thread-2]: Trigger "delta_set_REQ.js" - really changed: false

isFieldChanged returns true as the field was modified/touched but isFieldReallyChanged gives false as the value is same as before.

Hope that helps.

Hello pal,

Many thanks for your answer,

Can you share your code as mine doesn't work as expected ? 😞

****************

function print(s)

{

java.lang.System.out.println(s);

}

var significantFieldName1 = "Text";

var environmentBean = bsf.lookupBean("siEnvironmentBean");

var sb = bsf.lookupBean("imServerBean");

var delta = bsf.lookupBean("imIssueDeltaBean");

var isFieldChanged = delta.isFieldChanged(significantFieldName1);

print(delta.getIssueID() + " : $$$ isFieldChanged: " + isFieldChanged);

var isFieldReallyChanged = delta.isFieldReallyChanged(significantFieldName1);

print(delta.getIssueID() + " : $$$ isFieldReallyChanged: " + isFieldReallyChanged);

Thanks a lot!

It is basically same logic but the call to the method appears wrong, as it does not reference delta and gets no field value.

eb = bsf.lookupBean("siEnvironmentBean");
sb = bsf.lookupBean("imServerBean");
delta = bsf.lookupBean("imIssueDeltaBean");

eb.setMessageCategory("DEBUG");
logging = eb.messageCheck();
if (logging) {

eb.print("DELTATEST RUNNING");
eb.print("Running for item " + delta.getID());
}

eb.print("old: "+ delta.getOldFieldValue("Text"));
eb.print("new: "+ delta.getNewFieldValue("Text"));
eb.print("set to old value: "+ delta.getOldFieldValue("Text"));
delta.setFieldValue("ALM_Text",delta.getOldFieldValue("Text"))
eb.print("changed: "+ delta.isFieldChanged("Text"));
eb.print("really changed: "+ delta.isFieldReallyChanged("Text"));
