Dynamic field - AJAX refresh deleting field content

[duffy]

Hello,

We had been upgrading the OTRS from 3.1 version to 3.3. After the upgrade we are facing the problem with one of our custom dynamic fields. During the ajax refresh the content of the dynamic field get lost. Here is what we tried so far:
- Setting the AJAXUpdate property to 0 did not solve the problem
- Remove the field from the list of UpdateableFields same as previous
- Setting the IsACLReducible (to be reduded by ACLs and updatable via AJAX)to 0 seems to solve the problem, but we are not sure if this is the proper solution.

In the old version we used the IsAJAXUpdateable method which is not part of the 3.3 version.

We would like to know what should be the proper solution.

Thanks a lot!
