behavior : Cannot capture a date field to be empty

[zhangqian04]

I want to set another field to be required according to the change of one date field. When the date field changes from a certain date to null, another field cannot be triggered to be required。

explain：on this date Fields ，implement behavior

code as follows：

def timeField = getFieldById(getFieldChanged())

def formField = getFieldById("comment")

def cf = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectsByName("执行时间")[0]
def currentDate = (underlyingIssue?.getCustomFieldValue(cf) as Date)?.dateString

if ((timeField?.value as Date)?.dateString != currentDate){
formField.setRequired(true)
}
else
{
formField.setRequired(false)
}

 thanks for your response

It has been solved by “try”.

Hi, I might have misunderstood the problem here so I will summarise my understanding. 

When the date field does not have the current date make the comment required, is this right? 

I have created a similar behaviour, all you need is to define that you want the comment field to be required and add your code there. 

I am not sure what the getFieldChanged() does in your script as this will check every field in the screen rather than just the one that has the date?

I choose the field for the behaviour,  so capture this date time change.

now ,  when date time from a some value to empty value,this script cannnot capture change.
