Also reported to our error reporting back-ends

Also exists in n1_pos2_name flavor

[MauricioFauth]

To see this error as Fatal error: Uncaught ErrorException, you will need to have $cfg['environment'] = 'development'; in your config.inc.php file.

[shucontech]

Working on it.

[shucontech]

I'm unable to reproduce this issue. What exactly do you mean by Click refresh tree ? Also, it is Click on empty db or Click on an empty db ?

[williamdes]

You can repeat 1 and 2

[shucontech]

That's exactly what I did. Can't reproduce it on the demo server or the local machine.

Do you have it ?

[shucontech]

Do you have it ?

Yup, still can't reproduce.

[liviuconcioiu]

Do you have it ?

Yup, still can't reproduce.

I can reproduce it. Just go to index.php?route=/ and click on the refresh icon.

Still can't reproduce it. Maybe someone else can take up this issue.

[williamdes]

I wrote a test and could reproduce it, working on the fix now

[williamdes]

pos2 and pos3 implementation seem broken in some way

This issue was also reported as n0_pos2_value

Also found something wrong on pos3: 52fcbdf#diff-369499f525ad093000e69699d805d7e3ee9857219351069c80e86fbff1189084R110
