Constraint Type Field required on Task Editor after upgrading to 7.2.3

[empire]

We have upgraded to 7.2.3 and now the Constraint Type Field on the Advanced Tab of the Task Editor appears to be required (see attached).

We have even tried setting the required property but the behaviour persists.

 taskEdit: {
	 items: {
	 	advancedTab: {
			items: {
		        	constraintTypeField: {
		             		required: false

Please advise.

Can you reproduce this in our default samples? If not, can you please share a small test case with us so we can reproduce/fix?

We have found the cause of the issue with the latest release.

The constraintType data source must be null and not empty string.

Hello,

Yes, only undefined, null and explicit 'none' are considered to be valid nullish values for now. Due to this empty string is treated to be invalid.
Can you please let us know if this was working previously? If so in which version?

[empire]

Empty string worked in version 6x and earlier.
