Jasper domains taking too long to respond

Hi community,

I'm facing a really odd issue when trying to edit a domain on jasper server.

I'm able to open the domain designer where I need to make modifications and I actually get to change everything I need (Basically I just added some new fields).

But when I press the OK button, which is supposed to save the modifications I just made, it shows a Loading pop-up and freezes the screen. Then I have to close the browser and log in to Jaspersoft again.

Yesterday afternoon I made a test modifying a domain, clicked on OK and left the company after the loading pop-up appeared ... When I came to my desk today morning, it was still freezed.

It doesn't trigger any kind of message into the log files and also doesn't save my domain. It seems it just ignores what I've made.

Has anyone faced this issue? Do you have a clue on what to do or where to look deeper at?

I'm working with jasper version 6.4.

Thanks in advance!
