Hello Nicolas,

The problem with the Print format window is not a problem specifically with Trees but it is related to a refresh problem between Parent and detail records, because of this I've created a new ticket with your description " https://idempiere.atlassian.net/browse/IDEMPIERE-1048#icft=IDEMPIERE-1048 Sort tab lists not updated when master record change", Thanks for your feed back.

Regards,

Hi,

The issue is also reproductible on Print format window.
Steps:
Open the window.
Create a new record : master tab is empty, but DisplayOrder tab has items from previous record

Just my 2 cents : i've played a little with trees while searching for a patch and noticed that WTreeMaintenance was reloading trees using this code (action_loadTree()) :

if (tree.getModel() != null)
tree.setModel(null);
if (tree.getTreecols() != null)
tree.getTreecols().detach();
if (tree.getTreefoot() != null)
tree.getTreefoot().detach();
if (tree.getTreechildren() != null)
tree.getTreechildren().detach();

Maybe this should be preferred to

if (tree.getTreecols() == null)
{
...
}

??

Nicolas

Attaching same test case on swing to illustrate better the case
