dcm4chee-web3: 'Source AET' dropdown list is disabled or not populated

[leogrande]

I have upgraded dcm4chee from 2.17.3 to 2.18.3 and now I have this:
Web Application
Title: DCM4CHEE-WEB
Version: 3.0.7
Build: 18497

For some reasons the 'Source AET' dropdown list is disabled, but it worked for me with 3.0.1 (16430).

<select name="searchDropdowns:sourceAET" disabled="disabled" id="id43" title="Source AET (AET of SCU from which objects are received)">

Are there any related settings in the JMX Console?

Thanks.

It looks like in 2.17.3 /Roles - WebAdmin role by default has pre-selected AET. At least, I do not remember that I ever enabled it for this role.
After I enabled AET for roles in 2.18.3, it works now.
It was easy.
