Calling a Control Flow Case

Hello there, i have a task flow with 4 page fragments, and 3 Control Flow Cases, that basically does the navigation.
Im calling the task flow from a view.jspx that has 2 frames, left and center, the task flow its located at the center frame, and on the left frame i have 4 navigation buttons on that corresponds to each page fragment.
Now the problem is how can i bind my buttons to my Control Flow Cases of my Task Flow ???

Hi,
Without the use case, it's difficult, but the general idea is to have 4 task flows, one per menu item. Then, you add a single region to your page and change the task flow id in the page def for an EL expression. The EL expression has to point on a managed bean property that returns the right task flow id depending on the context. Finally, you have the menu items call the managed bean to activate the task flow id linked to the item clicked as the current task flow, thus displaying it in the region. That's the basic way to implement a region changing according to an action made in the container page. The Fusion develoepr guide has a more comprehensive and detailed explanation on dynamic regions.

Dialog control flow case not opening in new browser window

Hello -
Using JDev 11gR1.
I have a page fragment that contains a table of command links like so:
        <af:commandLink text="#{row.id}" id="cl2"
                        action="#{reportRunnerBean.runReportAction}"
                        useWindow="true" windowHeight="500" windowWidth="500">
          <f:param value="#{row.id}" name="reportId" id="p2"/>
        </af:commandLink>the runReportAction method returns the String: "dialog:runReport"
in my page flow, the page fragment has a control flow case with the outcome "dialog:runReport" that leads to a URL View with the URL setting set to #{pageFlowScope.reportUrl}
(the reportRunAction places a string in page flow scope with the key of "reportUrl". in case it matters, the url is external to the application)
When I click on the link, I am directed to the correct URL. However, it does not open in a new browser window - it takes up the main browser window.
Is there something obvious that I am doing wrong?
Thank you for reading this,
-- Scott

Well, I couldn't figure out why the dialog wasn't working correctly, so I changed my page to use a server listener to handle the logic I wanted and just used af:goLink instead of a command link. That command link above became:
          <af:goLink text="#{row.id}" id="gl1"
                     destination="#{row.reportUrl}"
                     targetFrame="_blank">
            <af:clientAttribute name="reportId" value="#{row.id}"/>
            <af:clientListener method="logReport" type="click"/>
            <af:serverListener type="LogReportEvent"
                               method="#{reportListBean.logReportInvocation}"/>
          </af:goLink>with the following client listener:
    <af:resource type="javascript">
      function logReport(evt) {
          var component = evt.getSource();
          var reportIdParam = component.getProperty("reportId");
          AdfCustomEvent.queue(component,
                               "LogReportEvent",
                               { reportId: reportIdParam}, false);
    </af:resource>and code in the bean:
    public void logReportInvocation(ClientEvent clientEvent) {
            String reportId =
                (String)clientEvent.getParameters().get("reportId");
            //...do something w/reportId here...
    }Thanks to anyone who took the time to read this.

Have you considered using router activity - http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/taskflows_activities.htm#CJHFFGAF ?

Control flow case to return from any page to start page!

I need to use a Image Link at Master Page for go to "Start page". but when i use control flow case don't work.
How can i assign a control flow case in a master page?
My djeveloper version is 11.1.2.3

You have to define what you mean by master page and start page. Are both pages are on the same talk flow?
What do you mean by 'the navigation doesn't work'? Do you get an error?
Normally you implement a wild card navigation which points to the start page. This navigation you use as target for the image link.
Please post the code of your image link.

FileDownloadActionListener then Control Flow Case Action

Hi guys!
I'm working on a bounded taskflow and I've a little problem......
I've put a fileDownloadActionListener in a command button and I can download a file fine.Now I want put another action listener to follow the control flow case designed in the bounded taskflow. Is it possible?
this is my commando button code:
<af:commandButton text="Conferma" id="cb1" action="cancel">
            <af:fileDownloadActionListener contentType="application/pdf;charset=UTF-8"

          </af:commandButton>thanks!!!

Thanks Zeeshan,
but your advice don't resolve my issue.... I forgot to say that my command button is in a popup dialog, this the entire code
<af:popup id="p1" animate="false">
      <af:dialog id="d2" title="Siete sicuri"
                 shortDesc="Siete sicuri di voler chiudere il veicolo?"

Bounded-Task-Flow Page Fragment Control Flow Help

jDeveloper: 11.1.1.0.2
I am having an issue trying to figure out the correct way to use control flow cases between a bounded-task-flow with page fragments and an unbounded-task-flow page. We have taken the approach in our application to have a few shell / container pages to host bounded-task-flows made up of page fragments to facilitate re-usability and to speed up development. There are 4 or 5 shell pages on the applications unbounded-task-flow. As of now, we have about 20 page fragments that are implemented as bounded-task-flows. These fragments don't do much now, meaning there is only a single fragment in each bounded-task-flow. The issue I am having is trying to invoke a control flow navigation action from one of the fragments to load a different shell page.
For Example, shellPage1.jspx contains fragment-flow-1 as a region. In my adfc-config.xml I have shellPage1.jspx and shellPage2.jspx, with control flow cases "toShell1" and "toShell2" respectively connecting the two pages. I have a link's action bound to the "toShell2" within the fragment that makes up fragment-flow-1. When the application is run, shellPage1.jspx and its fragment are displayed. But clicking on the link in the fragment ("toShell2") does absolutely nothing. It does not navigate me to the shellPage2.jspx as expected. What am I doing wrong here or do not understand?
If the fragment is included as a JSP include, and not a bounded task flow include, everything works as expected. This is not desirable as we then need to copy the fragment's pageDef into the shellPage's pageDef to get the DataControls to function.
If the faces-config.xml is used instead, and a JSF navigation case is used, it will also work as expected. This is not desirable because we really don't want to be mixing adcf-config and faces-config.
So I am really stumped here.... Thanks in advance!

Hi there:
In your case, the adfc-config.xml has the control flow case between shell pages. And the task-flow-N.xml or your-task-flow.xml for each page fragment by default doesn't inherit control flow case from their containing shell page. In your case, in the page fragment task-flow.xml, you should add a "Parent Action" to flow to shell page2 for example. The outcome of "Parent Action" would be "toShell2" if calling from ShellPage1 page fragment.
Is this 'Correct' or 'Helpful' for you? Please mark it as so if it does.
Good luck,
Alex

Calling Service Control from Page Flow

In Workshop for Weblogic Platform v10.0, we have a web service control in a page flow.
Although the web service call succeeds (as evidenced by a TcpMon monitor), the control method always returns null.
I'm guessing that although the call looks synchronous, it's actually behaving asynchronously - returning immediately with null.
Is this perhaps related to the particulars of calling controls from a Page Flow environment? Is it a bug in v10 of Workshop (Eclipse-based?
Thanks for any ideas!

Strange -- the PageFlowJspFilter adds no-cache headers to the response, so
if you're forwarding to a JSP from the action, then the browser shouldn't be
caching the result. What's in the URL bar in the case where your request is
getting cached?

Programatically calling control flows from java code

Hi all,
I have a bounded taskFlow that uses pageFragments. This flow is a region in a page(.jspx).
In my page fragment, I have a inputComboboxListOfValues with a ValueChangeListener code in a java bean.
I want when a value is changed, to programatically call "controll flow" (this one has: "From Activity Id" -the page fragment with that inputComboboxListOfValues, and "To Activity Id" - the default Activity on this task Flow).
So when the value change, practically I want to restart the flow programatically and pass the selected value as input parameter.
Since the inputComboboxListOfValues is not like a button where in the "Action" property you can set the Control Flow and navigate somewhere, the only option I have is to programatically cause navigation from java code (example: the value change listener code).
Can this be achieved?
Any advice is helpfull.

Hi,
Absolutely, you can do it using the NavigationHandler. Try the following in you value change listener:
FacesContext context = FacesContext.getcurrentInstance();
NavigationHandler handler = context.getApplication().getNavigationHandler();
handler.handleNavigation(context, null, outcome);
// Render the response after that phase, the button actions should not be called
context.renderResponse();
// Add the following line if you want to prevent further value change listeners to be called
// throw new AbortProcessingException();Regards,

Tutorial on AWT/Swing control flow

Greetings all,
Just wondering if any of you folks know of a good tutorial on AWT/Swing control flow? I'm doing some pretty complex stuff with a table whose editors call other windows and insert values into the table based on callback objects...weird stuff happening with loss of focus when the other windows come out, etc etc etc.
I have it working via a series of what I consider kludges, but I would really like to implement it cleanly, and it's looking like that's going to require understanding <ugh> <grin>
So it looks like it's time that I bit the bullet and got to grips with control flow in AWT/Swing. Is there a tutorial out there that could help me with this?
Many TIA

Let's take your word for it, but if you have the slightest doubt please consider the subject: EDT violation is a classic here.OK sure, but I really don't think I'm violating it. I avoid multi-threading like the plague, and only introduced it for my report writer because I wanted to have a little window advising the user that the report was in the process of being written.Raise your left hand and swear this report writer is not running when you experience the problem you describe! >o(
OK, this is just kidding, as per the rest of your description, it sounds reasonable now to assume that your problem is not related to EDT violation.
I'm doing some pretty complex stuff with a table whose editors call other windows and insert values into the table based on callback objects...This summary is a bit worrying, and I thought you would mention problems in the display of the table being edited. But you seem to refer to problems in other windows, or did I misunderstand?
Or do you mean, loss of focus in the editor still being edited? Can you please clarify what you do and what your problems are?
In particular, what does the other windows come out mean?OK, I was trying to be sparse with details because I didn't think they were relevant.Actually the worrying seems all the more justified, now that you have described it more extensively: I was afraid that you would raise other windows while editing, and that's the case. I know little of focus though...
I have a table in window A, one of whose columns has a custom editor which, when a cell in the column is double-clicked, registers itself with window B as a choice-listener (see later) then asks window B to come to the front. Window B, when the user performs a choice amongst the UI elements in there, fires a choice-event to its listener, i.e. the custom editor. At which point the editor saves away the chosen value (for use by getCellEditorValue()), sets the text in the cell appropriately, turns edit mode off via fireEditStopped(), and brings window A back to the front.
(...) once the custom editor asks window B to come to the front, the table in window A loses focus and when it is brought back to the front, the table's JScrollPane seems to have the focus (visually, it has the focus rectangle around it). Pressing the Tab key has no effect on focus; you have to use the mouse to focus something.I assume you have read the tutorial on using tables in Swing.
It contains an example where a custom editor is bringing up a dialog: http://download.oracle.com/javase/tutorial/uiswing/components/table.html#editor
AFAIK, the example does not suffer from focus problems.
What I am finding, and I reiterate this is new since I rewrote the windowing subsystem for the app (the custom editor was not changed in the rewrite), is that (...)Just what do you call "rewriting the windowing system" (just to rule out the possibility of something Ramboesque)?
I have no idea why this loss of focus is occurring, and I am at a loss to begin to figure it out. As I wrote above, I have a series of kludges which gets around the symptoms, but I would really rather figure it out and fix it.OK I admit I cannot tell what happens exactly, but:
1) instead of bringing window B to front, couldn't the editor bring up a dialog B (e.g. using JOptionPane.showXxxDialog() to bring up just the choice panel? The advantage is that it is more "synchronous", you can control when the window A's table model is updated.
2) what worries me too is that you update the model of the table being edited while you're editing one cell of it? Would it be possible, and make sense in your case, to update this model later (that is, post the model update as an invokeLater(...) call)? I don't see how seeing the table updating underneath helps the user editing its cell, but you may have your reasons.
What do you call flow control , or control flow in AWT/Swing?Basically, what I am after is something that will help me begin to understand/diagnose problems such as the above when they happen in my code. I am deeply averse to multi-threading (...) Things in my code were working, and that was enough for me.
But the above behaviour, and another weird behaviour I was having last week, which again I have solved with what I consider a kludge, and again which only began with my new windowing subsystem, have caused me to realise that it's time I really got to grips with this issue.Yes, when they say beware of threads when using Swing , nobody tells to not use threads! Just to be aware of how special Swing is with regards to threads (at least, compared to AWT, that didn't make such warning).
I would like, for example, to really deep-down understand exactly when listeners for AWT-Swing events get called. I don't really care so much when the events get put on the queue, but I do care when exactly my event handlers will be called. This will help me diagnose problems, I'm sure.Well they get called in the EDT, by some framework code that, in an infinite loop, does something along the lines of:
- pop next event from the event queue
- determine which is the target widget
- let the widget transform the event and send it to all registered listeners
Now with dialogs, things gets dimmer, because while a dialog is brought up (via a<tt>setVisible(true)</TT> call on the EDT, the EDT is indeed suspended, and a new event thread manages the events for the dialog).
I'm sorry I have no reference for that behavior, and my description is certainly blurry (and possibly wrong), but I don't think your problem is so much related to threading as I initially thought.
N.B.: Darryl's second link does features sequence diagrams that try to demonstrate what happen (in a specific example with asynchronous access, but you can derive the simpler, regular, working, from it).OK, yes I saw that diagram, I was offput by the asynchronicity but I will have another look tomorrow also. Thanks againDon't put too much hopes in there, indeed it's definitely not the kind of info I understand you're looking after.
Much luck all the same, and feel free to come back with your findings, or with more questions, about the initial subject (reference on event flow) and the specific problem (your focus issues with the editor).
I also cannot end this message without suggesting that you try to reproduce the problem with an SSCCE (http://sscce.org), that you could post here for us to try out. See this recent discussion about the multiple interests of this approach: {message:id=9587964}

How to call table control in subscreen in module pool program

Hi all,
I have req,need call table control in subscreen,but have done but when scroll bar value getting changed ,
please guide how to do it.if its possable send the code.
regards
santosh

Hi,
The navigation happens like this.
Consider you have a main screen and 2 subscreens.
When you click or do some event in the Subscreen 2 (lets say this is the one that has the table control), this will first trigger PAI of the Main Screen. In the flow logic of the Main screen, you would have written call subscreen <subscreen area1> and call subscreen <subscreen area2>.
Now the subscreens get triggered based on the order in which you have written in the flow logic.
So, here the modules before the first call subscreen statement in the Main Screen PAI is all executed. Now, it goes to the subscreen on which you have triggered an event and executes the modules in the subscreen.
This is how the execution goes when you have subscreens.
So there is no problem with the navigation. You only have to worry about the screen where you have the table control. Just debug and find where data is getting changed or duplicated.

Is it possible to call a task flow present in 1 ADF Mobile Application to another ADF Mobile Application?

In ADF Mobile, I want to call a task flow present in application1 to a different application2 on click of a button. Is it possible?

Hi,
This is my code to call the package.
String amDef = "model.service.DAFService";
String config = "DAFServiceLocal";
ApplicationModule am =
Configuration.createRootApplicationModule(amDef, config);
     CallableStatement cstmt = null;
     String stmt = "begin call CP_DAF_PKG.DAF_PROCESS(?,?,?,?,?,?,?,?,?); end; ";
     cstmt = getDBTransaction().createCallableStatement(stmt,0);
But in this case, I am getting
oracle.jbo.InvalidOwnerException: JBO-25301: Application module is not a root app module but has no parent
I understand the reason for this error. I need to call the
createcallableStatement from the application module that I have above.
Something like am. (call the package)
But not sure about any method which does that..
Please let me know if you know the way to solve it.
Thanks,

Does Crypto call admission control only apply to dynamic SAs?

Hi,
In my DMVPN phase 2 implementation, I have implemented crypto call admission control for IKE SAs on my spokes. This limit is set to 20 which is enough for my network.
I have three hubs per region and site-to-site connectivity is only enabled on one of these routers.(hub 3). hub 1 & 2 only provide connectivity to other resources outside the DMVPN.
If the IKE SA limit is reached on a spoke and there are other IKE requests which are being rejected - and let's say my hub1 goes down or the spoke just loses the tunnel.
Before the tunnels to the hub1 is recovered, the spoke accepts the IKE requests which it was previously rejecting and again the IKE SA limit is reached. Now the hub1 are back on line – it will not be able to establish a tunnel ,right?
If over a period of time the same thing happens with my hub2 then my spoke gets a bit isolated, right?
The hubs have static IKE policy (unique PSKs) while the site-to-site tunnels are dynamic.
In other words, does the crypto call admission limit apply only to dynamic crypto sessions or to all crypto sessions?
I think the former. In that case, can a priority be configured for the static IKE SAs over the dynamic ones?
Kind regards
Nasir

Nasir,
There should not be a differentiator for CAC between static and dynamic. It counts overall IKE and IKE in-negotiations SAs. IKE doesn't necessarily need to know whether session is static or dynamic...

You're right this is midleading, I'm going to get in touch with documentation team to make this a bit more explicit.

Calling bounded task flows imported as ADF libraries

Hello,
I have a main application referencing many bounded task flows included in ADF libraries.
Is there a way to make the application not throwing exceptions if one of these libraries including the called task flow is not found?
The first question is how to catch the exception "Caused by: oracle.adf.controller.ControllerException: ADFC-02001"
The second problem is that once an exception is thrown , the only way to make the application work again with that task flow is to redeploy the whole application with the missing library in the proper place.
It seems it is not possible to just add the library at run-time.
Redoplying an application also seems to invalidate all the current open sessions.
Could you give me suggestions or best practice on making the main application more indipendent from the libraries?
Thanks.

Hello Frank,
It seems there's no way to catch the exception thrown when dinamically calling a bounded task flow in a (missing) library. In facts, I added the single page of the main application as default exception handler activity. I also tried to catch ALL exceptions in the Launcher class below, but I had no luck at all. Task flows are called dinamically from this common piece of code (appropriate for the UI Shell template):
try {
if (newTab) {
TabContext.getCurrentInstance().addTab(title, taskflowId);
} else {
TabContext.getCurrentInstance().addOrSelectTab(title,
taskflowId);
} catch (TabContext.TabOverflowException toe) {
toe.handleDefault();
} catch (ControllerException ce) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (RuntimeException re) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (Exception e) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
I also tried to call the task flow in a remote application, but TabContext.getCurrentInstance().addTab(title, taskflowId) expects the taskflowid to be part of the main application, not of the remote app, since addTab() always add a "/" before the taskflowid String passes as parameter.
So again my question: is there a way to profit by the dynamic features coming along with the UI Shell template, where task flows can be really referenced and called each time at run-time, no matter if libraries containing these task flows are present or not when deploying the caller application?
I also repeat that from the tests I have done it looks like I can deploy the caller application without the referenced ADF libraries in their place (containing taskflows that should be called at run-time on user actions), but the problem in this case is that after that moment there's no way to fix the problem by just adding the missing library, that is you cannot place the library where it is expected to be and expect the caller to work after next call; this will just not work until next deploy of the calling application when libraries are in place . We also don't want completely separate web applications. We need task flows integration with the chance to modify and deploy these taskflows as ADF libraries at run time, separately from the caller of the taskflow, without needing to restart/deploy the caller application everytime a libraries changes or a missing library is added.

Better control flow?

Actually this is a general question I've been wondering for a while...
As the title states, I'm looking for a better control flow statement for what I planned.
I have 4 variables that determine types of pipe in a program in my main class. There are 6 possible pipe types.
For example Type 1 would have plastic grade = 5-7, color = 2, inner reinforcement = yes etc.
My main method determines which type the client chose, (if it matched one of the types or not so if all 4 were true then it matches x type.)
It's going to get really ugly if I use ifs and I don't think using a case statement would work.
Any suggestions in what I can use?

Unless you're just referring to getting user input and using it to look up a pipe >type?That would be what I'm doing, if I could figure out how to get the input variables from my applet class to the class that sorts out which pipe they picked.
Except the variables had to be defined within a method so the try catch statments could be added to them to catch the nfe as most of them are converted from String to int.
Let me suggest you to use nested switch case to solve the problemHmm, ok, I'll look into that. Would nested ifs suffice?

Why do we require Wildcard control flow rule?

Hi,
Why do we require wildcard control flow rule?
Can anyone please explain me with a scenario?
Thank you,
Srinivas

Wildcard rule means the rule is valid on all the taskflow's pages, so you don't have to wire the case separately from each page. Handy if you have for instance a button with a common action on many pages.
