Multiple events firing

Hi All,
I have 3 selectOneMenu listboxes. There is a dependency between them so that when one changes the others are reloaded. There are other dependent components on the page. I have defined separate valueChangeListener functions for each selectOneMenu and a single onchange javascript method which submits the form when any listbox is changed.
When a change happens in the first selectOneMenu, we return to the server, we go through the server side code and reload the various components. That's fine. At the end of that function I call renderResponse on the Faces context, however, for some unknown reason the event handlers for the other selectOneMenus get called immediately, too, and that messes up everything I have just done.
Why do all the event handlers get called when one of them changes on the client?

The lists used by the selectOneMenu controls are reloaded on the server.
I am using renderResponse in the valueChangeListener methods on the server to set that flag, so that when the other valueChangeListener methods fire they can check if renderResponse has already been set; if it has they do nothing.
That does work to stop the valueChangeListener methods from doing any unrequired processing, but I am now finding that the form fields do not refresh. Obviously the renderResponse is causing a problem with the construction of the form. Why would it do that? All I want it to do now is 'render the response'.
If I wasn't so stressed by the uncontrollability of JSF it would be amusing. As it is I am spending days on something I could do in 5 minutes using any other technology. I am not impressed.
The last thing you want when playing around with event handlers is a framework interfering in this way.
I can send you some source if you have time to look at it. How can I do that?

Event firing multiple times (et_Got_Focus)

Hi,
I just noticed while debugging my Add On code that the et_Got_Focus event which I have added to my event filters is triggered 64 times when I change a field value and then move to a different field. This not only happens in the matrix when changing field values and tabbing through but also in the header fields.
This has got to be a bug and it is not only slowing down the A/P Invoice form but it is potentially very dangerous to have an event firing 64 times when it should only be fired once.
To test this all one needs to do is add the et_Got_Focus event to the event filter with the A/P Invoice form, then add a debug statement to write out the itemvalue properties and you will see once you edit a value and tab you will get 64 statements that are the et_Got_Focus event, BeforeAction false for the same field or column when it should only occur once.
I have a very digrunted client that is very frustrated due to the amount this slows down data entry in the A/P Invoice. I cannot get rid of this event because there is a particular field I am monitoring for the got focus event so I can stop it under certain circumstances.
If anyone else has experienced this or knows how to resolve this please let me know. I guess if I don't find out why this is happening I will post a CSN to SAP.
Thanks very much,
David Wall

How do I select multiple events in iCal 8.0?

In OSX Mavericks, I used to be able to select multiple events in iCal in the event list view. I could select the initial event in the span of events to be selected. Then hold Shift while selecting the final even in the span of events. As a result, all of the events in that span would be selected.
in OSX Yosemite, this is no longer possible. There appears to be no list view, and holding the Shift button does not allow me to select a span of events.
What is the best way to select a span of events, say as much as 30 events?
Thank you.

How do I copy multiple events from a single calendar to another calendar?

I have multiple events from my "Family" calendar that I want to move. I would like to create a new calendar and move only specific events from my "Family" calendar to this new calendar. I have tried to select each event, then export, but this doesn't seem to work. It seems to export all events in the "Family" calendar, not just the ones that have been selected. Is there any way to do this aside from exporting each event one at a time and reimporting to a new calendar?

Drag them there. The volume they’re put onto needs to be formatted as Mac OS Extended.

Is there a way to create a multiple event screen saver from iPhoto events?

Is there a way to create a multiple event screen saver from photos in iphoto? I can create a single event screen saver, but don't know if it is possible to create a screen saver with more than one event.

Drag the events you want into an album and have the screen saver run from the album.

How do I split a single event with many clips into multiples events, one event per date?

I archived the video from my AVCHD camera into a Final Cut video archive. Later I imported this into iMovie. All the clips from this archive (spanning several months) are dumped into a single event. If I recall, older versions of iMovie would import video into separate events for each day. Then I would go through and give each event a meaningful name (e.g., "Mary's Birthday").
This is what I would like. Is there a way to split this very long event into multiple events, one for each day that is present in the event?

Not automatically but with imovie 10 you can create new events with any name you like then move clips into them from other events (Just like FCP 10.1). See:
http://help.apple.com/imovie/mac/10.0/#mov1d890f00b
You can also choose to display clips in an event grouped by date.

Can I have multiple event structures with the same event cases?

Hello,
I'm doing an application that reproduces the front panel of the HP6675A power supply. To achieve this, I have done a state machine with different states
(initialize, measures, voltage, current, ocp, ov, store, recall, etc). In each state, should have an event structure that catches the events of the buttons, like for example: if the current state is the Voltage mode and the user press the current button the next state will be the Current mode. For this in each state of the state machine should be the same event structure with the same events.
My problem is that the Vi doesn't work properly when I have multiple event structures with the same event cases. There are some possibily to do this, and how? Or is impossible to have multiple events? I have been reading some posts, but I don't find solutions.
Any help is appreciated.
Thank you very much.
Solved!

Or as others mentioned, make two parallel loops. In one loop, have your state machine. In the other, have just the Event Handler. Pass the events from the handler to the state machine by way of queues.
A proper state machine will not need the second loop. The "Wait For Event" or "Idle" state (whatever you want to call it) is all you really need in order to catch the user button presses. The setup is almost there. Maybe add a shift register to keep track of which state to go to in the case of a timeout on the Event Structure.

How to Disable Event firing while updating a list item using poweshell

Hi All,
I am working on a powershell code which updates most of the list items in the entire web application. I am using SystemUpdate($false) to update the items so that 'modified' and 'modified By' and versions are not changed.
However event receivers gets fired which is now a problem. I want to disable the Event receivers before update and enable it after update. I want powershell code for this. I am using SharePoint 2010.
Your help would be much appreciated. Thank you in anticipation.

Using Multiple Event Listeners

Hi,
I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.
the tweens are all unique to each movieclip
and the event listeners are taken off once completed.
This works all well and good in FLASH IDE...
My problem arises when I try to view this in a browser on a Windows XP
it doesnt work in
Opera Version 9.63
Firefox 2.0
and Google Chrome 2.0
The only browser it works fluently in is
Internet Explorer 7.0.5
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.
Is there any rule of thumb when using multiple event listeners?
here is a snippet of some of my code
on click event from movieclip (A)
private function scrollToSlidePrev(e:MouseEvent) {
               if (((slideIndex - 1) >= 0)) {
                    nextButton.mouseEnabled = nextButton.enabled = previousButton.enabled = previousButton.mouseEnabled = false;
                    var position:Number = 0-SLIDEAREA.width;
                    var slide1:TileListSlide = slides[slideIndex] as TileListSlide;
                    var slide2:TileListSlide = slides[--slideIndex] as TileListSlide;
                    scrollSlide(position,slide1,slide2);
tween animation in movieclip (A) on (B)
private function scrollSlide(pos:int,slide1:TileListSlide,slide2:TileListSlide) {
               slide1.resizeSlideTo(0.6); // execute tween on child movie clips in B
               slide2.resizeSlideTo(1); // same as above;
               var rect:Rectangle = sliderMc.scrollRect;
               var tween1:Tween = new Tween(rect,"x",Regular.easeOut,rect.x,rect.x + pos,3,true);
               tween1.addEventListener(TweenEvent.MOTION_CHANGE,setSliderScroll,false,4);
               tween1.addEventListener(TweenEvent.MOTION_FINISH,toggleButtonEnabled,false,3);
tween animation in movieclip (B) children
public function resizeSlideTo(sc) {
               var m:Matrix = tileList.transform.matrix as Matrix;
               var p:Point = new Point (m.a, 0);
               var tween2:Tween = new Tween(p,"x",Regular.easeOut,p.x,sc,3,true);
               if (numericStepper != null) {
                    if (sc != 1) {
                         numericStepper.visible = false;
                         tween2.removeEventListener(TweenEvent.MOTION_FINISH,showStepper);
                    if (sc === 1) {
                         tween2.addEventListener(TweenEvent.MOTION_FINISH,showStepper,false,2);
               tween2.addEventListener(TweenEvent.MOTION_CHANGE,setScaleOnScroll,false,3);
here is the link
http://visual_admin.web.aplus.net/ticker/ticker_widget.html
the effect disables and re-enables the buttons when its done.... then the listeners are removed.
each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
i really don't know what to make of it guys

apparantly making the tween a property of the class rather than a random variable in a function worked.....go figure

How do I purchase photos from multiple events?

I want to purchase about 10 photos from multiple events. I can't seem to figure out how to make that happen so I am not spending 2.99 shipping for 2-3 photos from each event. How do you cluster them all for one shipping fee?
Thanks

Make an album, drag the pics to that Album and use that for purchase.

Splitting photos without creating multiple events.

Is this possible? I have one event in iPhoto which covers three days. I would like all my photos from this event together but I want each day sectioned off in the same event, not split into multiple events. Highlighting the photos from each day and clicking "split" puts the days all in separate events where as I want them sectioned off, but together in ONE event. I hope I am making myself clear.
My aim is to have it looking something like this:
Event:
Day 1
Day 2
Day 3
NOT
Event: Day 1
Event: Day 2
Event: Day 3

tensocfan
Now with Events as you cannot have Nested Events, but it's perfectly possible with Albums:
File -> New Folder: Name it 3 Day Event
Then three Albums (you can even make them smart Albums: Date is Whatever)
And drag the Albums to the Folder.

Is it possible to handle multiple events using Jscript for a button in Apex

Hi,
I've application wherein in one of the pages for a button, I need to trigger 2 events as: 1. redirect to a new page upon 'click' of the button
2. display a set of values on 'mouse over' that button.
I'm able to handle both separately, but not in one button. I would like to know if there is any limitation in Apex that we cant handle multiple events? Currently I've put a text item near the button, and called the Jscript for mouse over event in that as a temporary workaround. Can someone let me know if this is feasible? If not any other alternative to handle this?
Thanks in advance,
gsachidh

Hi Gsachidh,
well interesting problem you're facinng. Indeed, it can't be specified using the 'Button Attributes' So we have to come up with an workaround.
A quick en dirty solution would be to specify it with the 'Optional URL Redirect options'. In a normal button, with processing on same page, this would be 'no target'. but in case of additional things to be done this can be used, using an target URL. I used this many times, in example with popUp windows for refreshing the caller object when changes are made. In your case we have to add next to the href an onmouseover event. this can be done with;
Target set to => URL
URL - target => javascript:doSubmit('<button_name>');" onMouseOver="javascript:showTooltip('tooltip');"
Here the " is the key, letting ApEx know the target (href) is doSubmit('<button_name>'), just like when no target would be specified and adding a new javascript event; onMouseOver.
Although this is a dirty solution in my opinion, it is the best i could come up with. I have another idea in how to do this, that is by adding this event dynamically with javascript with an addEvent. But i don't have an example at the moment for this scenario.

Event Fired when a mxml component is shown on screen

hello,
I have following application structure nested up to 2/3 level.
Application
     linkbar connected to viewstack
     viewstack
          NavigatorContent
               mxml Component
          NavigatorContent
               mxml Component
mxml componet in turn has similar structure
componet
     linkbar connected to viewstack
     viewstack
          NavigatorContent
               mxml Component
          NavigatorContent
               mxml Component
and end component is form which is shown and actions performed
I want to execute specific code when the form is first time shown
which will collect data from server and will show for further actions.
User will edit/delete/update data with various button clicks.
I tried activate event on end component but it seems that it wont get
fired at all. End components are enclosed in BorderContainer or Group.
To test activate event I have used Alert.show only but popup is not shown
when I select link button on penutimate linkbar.
If I am doing something wrong please let me know as well please
guide me which event shall I use so that whenever linkbutton is
pressed on linkbar it will fire that event. In that event I can check
whether it has been called earlier by checking some variable which
will be null in creation complete and set in event fired when linkbutton is pressed.
Thanks and regards
Raja

I think 'creationComplete' is the closest event to what you are looking for.

First event fired to event structure

Hi all,
Does anyone know what's the first event being fired to the event structure on VI startup? I set a breakpoint on the event structure and it breaks. However i wasn't able to capture whats the event.
My intention was simple; i have a table which list all the IO names and values. So during VI startup, i wan to populate the IO names first. Then in a timed-loop, the values are updated respectively. In this case, i don't need to "refresh" the table every time which waste time and resources.
It something like the OnLoad event.
Another way out is to register an user event, and have this event fired during application startup. But i wonder if anyone has a better way?
Many thanks!

Why don't you show us some code.
Are the IO name static for the duration of the program? Are you using a regular table column or the "row header strings []" property for the IO names?
If you want to write the row headers at the start of the program, place the code before the main loop containing the event structure. No event case needed. If you have a specific event to update the table headers if needed, fire the event once at startup using a signaling value property, again with the property node placed before the main loop.
