This is a long one...

Ok, I have this window that has a listbox, an "Edit" button, and a "Refresh"
button. The listbox has a onSelect event to enable the "Edit" button when a selection is made. The "Refresh" button resets the list and disables the "Edit"
button.

pseudo gui:

------
apple
orange
pear
------
[Refresh] [Edit]


Simple, the page works ok by itself. I added code to the "Edit" button to popup a modal dialog .zul page (to edit) and it still works ok.

Now, I create another .zul containing a tabbox where one of the tabs includes the above listbox window. Now when I press "Refresh", the "Edit" button does not show to be "disabled" or grayed out even though it's state on the server is disabled.

pseudo gui:

[Tab 1] [Tab 2] [Tab 3]
------
apple
orange
pear
------
[Refresh] [Edit]


The refresh function does:

final Window win = (Window) Executions.createComponents( "edit.zul", null, null); win.doModal(); btnEdit.setDisabled( true );

The above leaves edit button styled as enabled. If I change the code to the following, then it works.

btnEdit.setDisabled( true );
final Window win = (Window) Executions.createComponents( "edit.zul", null, null); win.doModal();

I see is behaviour in other gui elements too where gui look changes are not pushed to browser/client after the ".doModal()" call.

hope that explains it,
