Creation of persistent rooms from admin homepage throws NullPointerException

[sankar.balaji]

Hi,

I was trying to create Persistent Rooms using the Web Administrator ("https://localhost:8080/admin/"). While creating the room, I enabled the Flooding Filter and Language Filter by selecting "Yes" radio button for both of them. I also defined the parameters for them. The room got created. However, since then whenever I click on the "Persistent Rooms" link in the page, I am getting this NullPointerException ( see the detailed information below with stack trace )

Please let me know what is wrong here. I am not able to create any persistent rooms anymore.. :cry:

Exactly which version of ElectroServer are you using?

[sankar.balaji]

ElectroServer 4.0.4

[tcarr]

While we try to figure out what caused this, you might consider doing a complete uninstall then fresh installation. Set up the persistent room again, but please take a screen shot of the "Edit Persistent Room" tab just before you click the Save button. If the same error occurs, give us the screen shot as well as the full server log.

Never mind.. I dont want to screw up my current configuration of ES4 by uninstalling and installing it again.. However in future, if we take up ES4 completely, I would be doing some installation testing.. I will update this bug then. For now, I am happy creating rooms from my Actionscript code.

I have been unable to reproduce the error. If you ever figure out the exact steps you did, let me know.

I am having the same errors when simply creating a persistent room. I am selecting the default flooding and language filters. The error is occurring EVERYTIME and requires a full uninstall and reinstall....which is unacceptable right off of the shelf.

Attached are the screen shots. Below are the description of each image:

sshot-1.jpg >> Persistent Room creating screen with default filters selected
sshot-2.jpg >> Form after submit. Room variables and plugins now available
-- Navigate away from the Persistent Room area
sshot-3.jpg >> ERROR when loading the Persistent Room area using the primary navigation
sshot-4.jpg >> ERROR continued
sshot-5.jpg >> ERROR continued

The error is never resolved within the admin client and requires an uninstall and reinstall.

Please advise...

This has been confirmed as a bug and is currently being fixed.

good. hope to hear the solution soon.
i got dat bugs too.

[sondun2001]

Any luck on this bug? I also have it. Is there a way of removing this configuration without having to completely uninstall electroserver? Thanks. I do believe it was related to the language filter
