Please detail your use case.
This description is not precise enough to analyse a potential issue.

Ok. On Problems screen, when I click on the button to change workflow status (the button on the right of the state field), the date on handled or done field stay empty, even if the chekbox on the left is checked. I think one click on this button have to check thoose boxes and fill thoose date fields but I can be mistaking. I have to fill dates manually.

On Problems screen

do you mean "Issue" screen ?
Only on this screen ?

I cannot reproduce.
Please give more hints.
Any error in the browser console ?
Any error in the log file ?
Please provide print screen.

Sorry you're right, I mean issue screen (bad translation...).
I tested pushed my investigation and the issue was from me : I created another type of issue, and didn't checked de right boxes on the behavior section...
Sorry

I come back with my problem. It works great on Issues screen but not on tickets.
When I select the workflow state in the dropdown list, dates are written in the right place. But when I click on the button, the date appears a few seconds, then dissapear.
I think the configuration is now ok in ticket type screen but still don't work. You can see that on screenshots joigned.
Nothing on log file, nothing on console.

the date appears a few seconds, then dissapear

Dou mean that when you select a new status in this list (not using direct change button to next status) the checkbox is checked and the date is set, but few seconds after (doing noting, not saving) the date is cleared ?

No, when I select a new status directly on list, everything is OK. But when I click on the button :
- Box is checked
- Date is set
- A message appears to tell an email was sent
- when this message dissapears after dfew second, at the same time date dissapears too, doing nothing

OK,
I could reproduce with done date and closed date, but not with handled date.
And this is produced only if type has "lock done" and "lock closed" uncjecked (if they are checked, there is no issue).
Do you confirm it is same case for you ?

Found it !
It was an asynchronous issue, so not systematic.
To fix it, in /view/objectDetail.php, replace line 1370

          echo ' onClick="dijit.byId('' . $fieldId . '').set('value',' . $next . ');setTimeout('saveObject()',10);">';

with

          echo ' onClick="dijit.byId('' . $fieldId . '').set('value',' . $next . ');setTimeout('saveObject()',100);">';

Ticket #1768.
Will be deployed in V5.0.4 (coming very soon)

It works 🙂
