Thierry Danard commented on NETBEANS-1792:
------------------------------------------
I downloaded the latest version from GitHib
(https://github.com/apache/incubator-netbeans). This is the code I retrieved
for BooleanStateAction:

This issue is present when I run NetBeans from code or from from the vc4
binaries. I'll create a small module to reproduce.

> I used the latest release candidate of NetBeans 10 (vc4), and found that
> BooleanStateAction fires two "booleanState" events instead of one when a
> button backed by a BooleanStateAction is pressed, the first event reporting
> that the state is changing to "true", the second event reporting that the
> state is changing back to "false" (even though the button is still showing as
> "pressed")
> In my case, this BooleanStateAction is inside a JToolbar.
> javax.swing.JToolBar toolbar = new JToolBar();
> toolbar.setFloatable(false);
> toolbar.setRollover(true);
> Component tp1 =
> SystemAction.get(MyBooleanStateAction1.class).getToolbarPresenter();
> Component tp2 =
> SystemAction.get(MyBooleanStateAction2.class).getToolbarPresenter();
> Component tp3 =
> SystemAction.get(MyBooleanStateAction3.class).getToolbarPresenter();
> tp1.setFocusable(false);
> tp2.setFocusable(false);
> tp3.setFocusable(false);
> toolbar.add(tp1);
> toolbar.add(tp2);
> toolbar.add(tp3);
> JPanel toolbarPanel = new JPanel(new BorderLayout());
> toolbarPanel.add(toolbar, BorderLayout.WEST);
>
> This is a breaking change, it was working just fine in NetBeans 9. It breaks
> a lot of code in my app as I rely on the booleanState event to enable to
> disable behaviors: right now, when a user clicks a button, it shows as
> "pressed", but the associated function gets disabled right after it gets
> enabled.
> I wasn't able to find a root cause after running from NetBeans source.
> I did note that the BooleanStateAction is deprecated.
> I'll try to provide a sample code to reproduce.
