Justin Mclean updated FLEX-34364: --------------------------------- Labels: easytest (was: ) > FlexEvent.BUTTON_DOWN events are sometimes lost > ----------------------------------------------- > > Key: FLEX-34364 > URL: https://issues.apache.org/jira/browse/FLEX-34364 > Project: Apache Flex > Issue Type: Bug > Components: Spark: Button > Affects Versions: Apache Flex 4.12.0 > Environment: Mac OS X 10.9, Apache Flex 4.12.1 + AIR 13 > Reporter: Tamás Nepusz > Priority: Minor > Labels: easytest > Attachments: ButtonDownBugTest.fxp > > > {{FlexEvent.BUTTON_DOWN}} events are sometimes not fired for Spark Buttons. > More precisely, they are _usually_ not fired (in ~80% of the cases) when I > click on the button by tapping the touchpad of my MacBook Pro _and_ the > window that contains the button is not the first window of the application. > The events are _always_ fired properly when I click on the button using the > mouse or the button at the bottom of my touchpad, _or_ when the button is > contained in the first window of the application. > I strongly suspect that this happens because {{FlexEvent.BUTTON_DOWN}} events > are dispatched in {{ButtonBase.commitProperties()}}, but the > {{MouseEvent.MOUSE_DOWN}} and {{MouseEvent.MOUSE_UP}} events happen so > quickly when I tap the touchpad that {{ButtonBase.commitProperties()}} only > gets a chance to run when the button is already up again (although this does > not explain why it is not a problem for the first window of the application). > This is not a big issue on its own, but note that {{DropDownController}} > relies on the {{BUTTON_DOWN}} event to decide when to open the dropdown in a > {{DropDownList}}, so Spark dropdowns do not work reliably in the presence of > this bug. > Steps to reproduce: > # You might have to get a Mac to reproduce this issue. > # Open the attached project. > # Tap on the button of the first window that opens using the touchpad. Note > that you get both a {{BUTTON_DOWN}} event and a {{CLICK}} event, and these > are logged properly in the list shown below the button. > # Open a new window by clicking on the button in the lower right corner. > # Tap on the button of the new window a few times. Note that {{CLICK}} events > are always dispatched, but in ~80% of the cases they are not preceded by a > {{BUTTON_DOWN}} event. -- This message was sent by Atlassian JIRA (v6.2#6252)
