While trying to release the activities in NWDS a problem occurred and I got this error message:

Here's the error log:

I'm using NWDS Version: 7.0.18.

Can anyone offer me any suggestions to solve this, please?

Thanks!

Hi Emilia,

Could you check if there are any dependent DC's for which activity has not been released.

According to the error that you are getting in the second screenshot, it seems some previous activity has not been released.

Hi Rohit ,

There were actually some activities not released for the dependent DC's.

These activities were done by another consultant back in 2011, tho I don't know what he did.

Is it possible to delete these activities?

Best Regards,

1.try with another ide,

2. what role you have for the nwdi?

[rohit_singhal · Accepted solution]

Hi Emilia,

You can try the following options:

1. Try importing the configuration for the track again (creating a new version: say <trackname>[1]), and then try making the changes followed by releasing the activity.

2. Second, if the above option does not work for you, you can view the changes in the activities which are waiting to be released and rollback (revert) the changes.

Do let me know in case this resolves your issue.
