Javascript embedded in button pl/sql event handler not being executed

Javascript calls not working from pl/sql button event handler. What am I missing? Are specific settings needed to execute javascript from pl/sql proceedures?
Example: Want to toggle target='_blank' off and on in a button pl/sql event handler to open url call in new window & then reset when processing submit is done & the app returns to the form.
portal form button's pl/sql submit handler:
begin
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
end ;
Putting the following in the button's javascript on_click event handler works great:
this.form.target='_blank'
to force opening new window with a call in the button's submit pl/sql code via:
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
but then the target='_blank' is left on when the submit is done & we return to the form.
putting the above javascript as a function (called fcn_newpage) elsewhere (e.g., after form opens) & calling in the submit pl/sql with
htp.p('fcn_newpage') ;
also doesn't work.
Metalink thought this was an application issue instead of a bug, so thought I'd see if anyone knows what's going wrong here. (Portal 9.0.4.1)

thanks for your discussion of my post.
Please clarify:
"htp.p('fcn_newwindow') sends a string":
What would you suggest the proper syntax for a function fcn_newwindow() call from a pl/sql javascript block that differs from
htp.p('<script language="Javascript">') ;
htp.p('fcn_newwindow');
htp.p('</script>');
or more simply
htp.p('fcn_newwindow') ;
More generally, what I'm trying to figure out is under what conditions javascript is executed, if ever, in the pl/sql of a button (either the submit or custom event handler, depending on the button).
I've seen lots of posts asking how to do a simple htp.p('alert("THIS IS TROUBLE")') ; in a pl/sql event handler for a button on a form, but no description of how this can be done successfully.
In addition to alerts, in my case, I'd like to call a javascript fcn from a pl/sql event handle that would pass a URL (e.g., http://www.oracle.com) where the javascript fcn executed
window.open(URL). The API call to set_target(URL) in pl/sql has no ability to open in a new window, so calling that is inadequate to my needs and I must resort to javascript.
Its clear in the PL/SQL of a button, you can effect form components since p_session..set_target & p_session.get_target set or get the contents of form components.
So to see if javascript ever works, I tried to focus on something simple that only had to set what amounts to an enviromental variable when we returned to the form after a post. I chose to try to change the html value of TARGET from javascript in the PL/SQL button because it doesn't need to be implemented until we finish the post and return to the form.
So I focused on a hack, setting this.form.TARGET='_blank' in the on_click event handler that forced every subsequent URL call or refresh of the form to be a new window. I then wanted to turn off opening new windows once I'd opened the URL call in a new window by setting TARGET='' in the portal form. I can achieve what I want by coding this.form.TARGET='' in the javascript (on_focus, on_change, or on_mousedown, ...) of every form component that might refresh the form. However, that is a ridiculous hack when a simple htp.p('<script>') ; htp.p('this.form.target=""') ; htp.p('</script>') ; at the end of the button's pl/sql event handle should do the same thing reliably if javascript ever works in the pl/sql event handler.
If we didn't have access to form components through p_session calls, I'd assume it was a scope issue (what is available from the pl/sql event handler). But unless my syntax is just off, when, if ever, can javascript be used in a portal form's pl/sql event handler for a button?
if I code a javascript funtion in the forms' pl/sql before displaying form:
htp.p('<script language="JavaScript">') ;
htp.p('function fcn_new_window(URL)') ;
htp.p('window.open(URL)' ) ;
htp.p('</script>') ;
the function can be called from a button's on_click javascript event handler:
fcn_new_window('http://www.oracle.com')
but from the same button's pl/sql submit event handler this call doesn't work: htp.p('fcn_new_window("http://www.oracle.com")')
So my questions remain: Is there other syntax I need, or does javascript ever work properly from the pl/sql of a form button's event handler? If it doesn't work, isn't this a bug that should be fixed by Oracle?
I can probably figure out hacks to make things work the way I need, but executing javascript from pl/sql event handlers seems to be the expected way to affect portal html pages (forms, reports, ...) and it seems not to work as expected. I don't feel I should have to implement hacks for something as simple as calling a javascript function from pl/sql when almost every example I've found in metalink or the forums or Oracle Press's "portal bible" suggests using javascript from pl/sql via the utility htp.p() to effect web page components in portal.
My TAR on the subject, while still open, returned the result basically: "We can reproduce your situation. Everything looks okay to us, but we can't explain how to use javascript where you want or point you to any documentation that would solve your problem or expain why it should not work the way you want it to. We don't feel its a technical issue. Why don't you post the problem on the portal applications forum."
I'm hoping I'm just missing something fundamental and everything will work if I implement it a little differently. So if anyone sees my error, please let me know.
by the way, not sure this is germain, but in reference to your comment:
"redirections in pl/sql procedures give a peculiar result. in a pl/sql procedure, usually, portals give the last redirection statement and ignore anything else coming after it."
if I try to raise an alert:
htp.p('alert("you screwed up")');
return;
in a pl/sql event handler, it still doesn't raise the alert, even though its the last thing implemented in the event handler. But if I set the value of a text box using p_session..set_value_as_string() at the same spot, it correctly sets the text box value when I return to the form.

Event Handling in BSP

Hi guys,
i need the framework of event handling in BSP. if have multiple controls on my BSP (with flow logic, how ican capture each event occured by each control.
a- i have two radiobutton groups, each have two radiobuttons.
b- i have a tableview, if user select a row i need the value of the selected row.
c- i have a button, onclick i want to handle all the events, checked radiobuttons value, selected row to do a action or navigation.

in the event click of the button (oninputprocessing)
you can get the value of other objects (radiobutton, tableview etc,
you have to do something like below.
for tableview
DATA: table           TYPE REF TO cl_htmlb_tableview .
table ?= cl_htmlb_manager=>get_data( request = request
                                            name    = 'tableView'
                                            id      = 'TV1' ).
for radiobuttons
data: radiobuttongroup1 type ref to cl_htmlb_radiobuttongroup.
data: radiobuttongroup2 type ref to cl_htmlb_radiobuttongroup.
radiobuttongroup1 ?= cl_htmlb_manager=>get_data(
                        request      = runtime->server->request
                        name         = 'radioButtonGroup'
                        id           = 'RBG1' ).
if radiobuttongroup1 is not initial.
r1sel = radiobuttongroup1->selection.
endif.
radiobuttongroup2 ?= cl_htmlb_manager=>get_data(
                        request      = runtime->server->request
                        name         = 'radioButtonGroup'
                        id           = 'RBG2' ).
if radiobuttongroup2 is not initial.
r2sel = radiobuttongroup2->selection.
endif.
Hope this helps.

What's different between event handle by bsp frame & MAC

Hi,
Can anyone know the different between event handle by BSP frame & handle by MAC?
and how to know which event is handle by BSP frame or MAC?
thanks

Hi Abdul,
So that means the add_entry event is standard event handle by BSP frame.

Raise a button's click event handler from another event handler

hi,
I am trying to raise a button's click event from another button's click event.
Automation gives a runtime error. I checked out some other forums for answers but they dont work when called from another event handler.
Console.WriteLine(gestureData.name);
if (s==b2) ;
//raise button2's click event
private void b2_Click(object sender, RoutedEventArgs e)
MessageBox.Show("I am button2");
private void b3_Click(object sender, RoutedEventArgs e)
MessageBox.Show("I am button3");
Any help will be appreciated.
Thanks,

Hi Andy,
I tried to implement your suggestion.
What I am trying to do is, say there is a label whose content property needs to be updated every time a button b1 is clicked. When the button is clicked , it check if a condition is met and depending upon that condition it updates the content of the label
. Say , if the text entered is "add" and the button is clicked and the label's content is set to "add", if the text entered is "sub" and then the button is clicked, the label's content is set to "sub".
I understand that there is no need to fire up different methods for this as this can be done by checking for conditions in the same button click event but it seems that updating the UI is not happening. I get an error saying.:
A first chance exception of type 'System.InvalidOperationException' occurred in WindowsBase.dll
The program '[6660] WpfApplication8.vshost.exe: Program Trace' has exited with code 0 (0x0).
The program '[6660] WpfApplication8.vshost.exe: Managed (v4.0.30319)' has exited with code -1073741819 (0xc0000005) 'Access violation'.
this goes away when I remove the Label.Content="add" or Label.Content= "sub";
I think the label's content property does not update dynamically.

Loader not triggering events

Hi everyone,
I am not sure this is the right forum to post in. I am developing an inDesign extension in actionscript and I've drawing my own components which are supposed to retrieve an JPG image from the web and display it within the extension interface. I tried to use the Loader class to retrieve the image but none of the events are fired. Alternatively I tried using URLLoader, which does trigger events, but returns a ByteArray that I have to convert back to BitmapData. So I'm back to my original issue, my code in the "complete" event handler is never executed. Note that I tried to trigger "init", "progress", and "security error" as well, none of them are triggered. My code looks something like that:
public class LayoutTileRenderer extends VBox
   private var coverBitmapData:BitmapData;
   public function loadImage(imageByteArray:ByteArray):void{
        var bitmapLoader:Loader = new Loader();
        coverBitmapData = new BitmapData(84, 118, true);
        bitmapLoader.addEventListener(flash.events.Event.COMPLETE, function(e:flash.events.Event):void {
             trace("Loaded completed");
             coverBitmapData.draw(bitmapLoader);
             // then draw the bitmap
        bitmapLoader.loadBytes(imageByteArray);
   override protected function commitProperties():void{
        super.commitProperties();
        ... // retrieve imageByteArray via URLLoader
        loadImage(imageByteArray);
Does anyone have a clue why the events are not triggered. And otherwise has a better way of converting the bytes I get in my URLLoader to BitmapData for display?
Thanks in advance for your help.

Well well, I solved it. I was missing "contentLoaderInfo".
bitmapLoader.contentLoaderInfo.addEventListener(...)
And I really have no excuse since it's really all over the doc...

How to configure which changes in the document triggers Event Handler again

Hi Experts
Due to some reason after creation of Purchase Order, the event handler is not created in EM system. Now is there any way to resend this PO to EM? For example, is it possible to trigger Event Handler by changing some field in PO? If it is possible that way, Could you guide how to configure which changes in the document (PO/SO/Delivery/Shipment) can trigger Event Handler in EM system?
Thanks
Ravi

Hello Ravi,
if you change the PO Header/Item the respective EH should be created if the Relevance condition is fullfilled.
I'm not sure if it also works in the case that you change the PO Header and EH for PO Items will be created.
Best regards,
Steffen

There may be multiple reasons for this.
1. SharePoint timer Job is malfunctioning:
For this try restarting SharePoint timer Job. through SP Powershell:
Stop SPTimerv4 , Start SPTimerv4
2: SharePoint Cache is full:
Reset SharePoint Cache by deleting all XML files ( except cache.ini
) in SharePoint Cache located in System Drive\ProgramData\Microsoft\SharePoint\Config\<GUID>
3: Check if Microsoft Project Server Event Service is running in Services.msc, try restarting it.

Daqmx "Done" event not triggering event structure

I would like the user to be able to abort my daqmx task by pressing a button.
I am attempting to use the method in this VI:
https://decibel.ni.com/content/docs/DOC-15815
It utilizes an event structure with the daqmx Control Task VI to abort.
The example VI above works for me, on my system with my USB-6356 device, as expected.
When I attempt to incorporate the same method into my VI it does not--despite having an identical arrangement, so far as I can tell.
I believe that my problem lies with the event structure, and the dynamic registration. I am unfamiliar with this and must be using it incorrectly.
I have attached my VI, though it is cumbersome. The code which I am struggling with is in the "Acquire" case. As far as I can tell, I am doing exactly the same this in this particular case as in the example mentioned. Yet in the example, the event structure completes, or aborts, whatever you want to call it, right after the "Wait Until Done" VI executes. In my own VI, the "Wait Until Done" and "Clear Task" VIs execute, but the event structure does not register it.
Here are my specific questions: is there anything extra or special that one must do in order for the Task to properly trigger a "Done" event and pass through the event structure? At what point is the daqmx task "Done"?
thanks,
Matt

natasftw,
My event structure is identical to theirs; what you are seeing are the two different cases that exist in the event structure. In both the example and the VI, there is a <task out>: Done and a "Dynamic Event": Value Change. In the dynamic event case, I have my abort button and relevant code--this I believe is the code you were referring to, which you thought I was missing... Regarding my multiple event structures, they should operate completely independently as they respond to different events.

STRUTS and UIX: How to use getCustomMethod in event handler

I am having app module method exposed to a client as my custom method that does something. Then I have a data page (UIX) with a submit button that triggers event handler:
public void onMyEvent(DataActionContext ctx) {
    HttpServletRequest request = ctx.getHttpServletRequest();
    HttpSession session = request.getSession();
    JUCtrlActionBinding method = ctx.getCustomMethod();
    if (method == null) System.out.println("method is null!!!!!!!!!!!");for some reason my method handle is null WHY???
this seems to work when I call my method from findForward() though.

If you use ADF BC, you can override the method create(AttributeList) in the Entity Object implementation class (EmployeesImpl.java).
Use: Menu --> Tools --> Override Methods --> create
In the overridden create method you can assign the next value from a DB sequence (e.g. EMP_SEQ) to the ID attribute:
protected void create(AttributeList nameValuePair) {
// Super
super.create(nameValuePair);
// Id
SequenceImpl s = new SequenceImpl("EMP_SEQ", getDBTransaction());
setEmployeeId(s.getSequenceNumber());
}

Work Flow - Triggering Event through Webdynpro

Hi,
I am new to Workflow. I have generated the Workflow related to claim (Objects as ABAP Class). Now I have generated Webdynpro component and through this I need to execute the Workflow. I have used the FM SAP_WAPI_START_WORKFLOW & SAP_WAPI_CREATE_EVENT. To raise the event 'cl_swf_evt_event=>raise'. I have used. But this is not triggering event. So, Any one can help me on this issue.
In workflow using ABAP CLASS is essential or Business object.
In my case I have used only ABAP CLASS. In workflow I have generated the Triggering event as SAVE. In webdynpro I have generated the code in 'ONACTIONSAVE'. When ever the user clicks SAVE' button. Workflow shouild trigger and approver should receive the mail as notification and he/she will approve/reject the claim.
Thanks & Regards
Kannappan

After SAP_WAPI_START_WORKFLOW do you have COMMIT WORK?
Does the SAP_WAPI_START_WORKFLOW return some error message?
Are you sure that the event is not triggered? Check this with event monitor SWEL (turn monitor on in SWELS).
Also, ready Jocelyn Dart's blogs about ABAP OO. She have clear instructions about how to trigger ABAP OO events.

EDIT: BAH! I posted too slow... but there is still some information about saving and clearing in there
Its for making a playlist while your 'on the go'. So you click and hold the middle button the selected song (or album) should flash... Then you go into the playlist menu (music>playlists>on-the-go) and use it like any normal playlist...
When there's songs on the playlist it gives you the option to save or clear at the end of the song list, you select either one and it'll ask for conformation.
It works in both manually sync and auto sync mode. But if you have it on auto sync the play list will be created in iTunes...
So I'm not sure why you don't see songs in it after yo assign them to it, try sending a whole album and then music>playlists>on-the-go the album songs should be listed.
As for reasons to use it well maybe while out and about you realise that you want to hear from two artists at the same time, Radiohead and Bowie, in a shuffle mode. You could make it a on-the-go playlist. Or there's a few podcasts you want to hear in order... so you go down the list and assign them to on-the-go.
Some people use the On the go to note songs that need to be looked at in iTunes later, maybe because its too quiet, badly imported or they don't understand how such a bad song found its way onto the iPod.
Once you save it if you try and put more songs to it, 'on-the-go-1' will be created.
-hope this helps

Val(sgnl) Property of a Button to Fire Event

I'm trying to call a button value change event handler by using the Val(sgnl) property of a button control. Its not working. Ive done this with boolean controls and it works great. The boolean version takes a boolean input while the button version takes a variant - I'm not sure why there is a difference. I tried it by wiring a T/F directly into the property, and using a Data To Variant to convert the input, but neither works.
Thanks,
Bill F

Bill,
I think I have the answer for you. I knew I had done this before so I started to create the attached VI. Well I ran it and got an error, thus I think the answer.
The button can not have a mechanical action of "Latching". If you change the button to switching it should work fine. I have attached a working VI.
