ADF task flows and parameters WITHOUT data controls

Hello world.

In a previous post, I asked him about the best way to call the workflow "at a distance" by a "local" application Frank Nimphius suggested me to use the JAR ADF libraries between projects for this. I'll apply, but I have a small/big problem:

As I said in my previous post, I exclusively use the EJB 3.0 - JPA technology in all my projects. The components business or data controls are used. Just a lot of Java-based components.

Now, supossed that I have a (based in the HR schema) application with 3 projects:

-L' one with all things EJB: entities from tables, session bean, and an example of a Java client.
-The second as a 'local' point of view, with a JSPX (viewLocations.jspx) page that contains the table of communities (table_locations).
-The third view "at a distance", with a JSPX too (viewCountries.jspx) page that contains the table of countries (table_countries).

I have a button in views the remote, and one to switch from local to remote display and the other for the opposite.

The goal is: pass a location of choice of table of locations for the project where I need to see the country for the selected location.

In the table of locations, I use a variable currentLocation (declared as: private location currentLocation = new Locations() ;) to store the selected location and a SelectionListener process, called selectLocation_listener() with this code in the)
backing.viewLocations.ViewLocations.java:

+ ' public void selectLocation_listener (SelectionEvent selectionEvent) {+
+ / / Add code from the event here... +.
currentLocation = (rentals) table_locations.getSelectedRowData ();
+}+

If the selected location is stored in the variable currentLocation.

Both in projects the and remote, in that I store the task flow JSPX pages. I have the taskLocal.xml as an unlimited workflow with the viewLocations.jspx as the main view and the taskRemote.xml as a workflow bounded with the viewCountries.jspx as the main view.

I have deployed the project remotely in a library JAR ADF and imported to the local project, then I get it as a special activity Flow call.

The question is: How can I pass the variable currentLocation as a workflow setting to my project remotely? I don't have any data control to bind to a workflow parameter.
Should I really have some control of data to store my currentLocation variable and bind it to a parameter? Or there is another way without data controls?

Another fact: local and remote project have a dependency with the EJB project.
What about dependencies? Have a role in call task workflow activities?

Thanks in advance.

If you would like more information or a more detailed explanation please ask me.

Hello

a data control is needed for this. If you only want to use ADF task Flow and manage the component UI lie yourself, then you are good to go with this approach. To add parameters to a call from bounded task flows, have a look here

http://download.Oracle.com/docs/CD/E15523_01/Web.1111/b31974/TOC.htm (Chapter 15, activities of view URL using 15.3)

You can make the local variable that is accessible from an accessor method Set/getter bean managed so that you can use EL when you set the value of the parameter.

  • Info by exception display JDev 11.1.2.1 ADF task flows activity

    Article 22.4 of the 11.1.2.1 Fusion developer's guide tells me how to designate an activity as the exception handler for a workflow. I followed the directions; created a page error, placed in the workflow, marked as the exception handler. I force an exception and indeed the page.

    What I don't know is how to extract the data of the exception, so I can filter, format and display it. How is the exception page receives the exception data?

    This level of exception is adequate handling? All my treatment in the workflow. If each of them has an exception handler is something more, what I should do to catch exceptions alll?

  • Input parameters of the task flow and "back" button

    Hello experts. I have two stubborn workflow created by page; say they are TF1 and TF2. Each workflow task has their own controlled beans. These controlled beans are kept in the Page flow scope. The two task-flow has their own of initializers.

    By an action on TF1, I redirect to the TF2. During this redirection, I pass some parameters. After redirection when it enters the TF2, I extract the parameters programmatically. Now I'm back on TF1 and TF2 of TF1, I'm clicking on the back button of the browser. Note that I put anything if the re-entry allowed or not in TF2. After clicking the browser back button access me for the new TF2. TF2 called if I generate any action of the initializer. BUT now I can not get the input parameter values more. All values in the set of input null parameter.

    My question is:

    • Why have defined null values?
    • How can I make persistent values?

    Any pointer would be very useful.

    I use JDeveloper 11.1.1.6.0, WebLogic 10.3.5.

    Thanks in advance.

    There is a way. Click on "back" button is not invoke the lifecycle JSF and browser displays the previous pages in its cache. If somehow, I can say browser not to cache the page, then every time a click the back or next button, the browser would GET the page headed from the server, which would eventually be my.

    So I added a filter to achieve this:

    public class NoCacheFilter implements Filter {
    @SuppressWarnings("unused")
  private FilterConfig _filterConfig = null;

    public void init(FilterConfig filterConfig) throws ServletException {
        _filterConfig = filterConfig;
    }

    public void destroy() {
        _filterConfig = null;
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse servletResponse = (HttpServletResponse) response;
        servletResponse.setHeader("Cache-Control","no-cache, no-store, must-revalidate, private, max-stale=0, post-check=0, pre-check=0");
        servletResponse.setHeader("Pragma", "no-cache");
        servletResponse.setHeader("Expires", "Sun, 16 Dec 1984 07:48:00 GMT");
        chain.doFilter(request, response);
    }
}

    Note that I have to specify browser to cache resources, I do R & D to change this filter.

    It works. Hope, now I can spend my weekend peacefully :-).

    Hello

    It contains only the activity of the method, and if so, why is he launched with the help of a new transaction? Note that navigation always is an ID of the view and the workflow will not run if there is no view to navigate to. So either the calling flow calls this workflow and workflow returns immediately after execution of the activity of default method then it refers to a display of flow tasks calling or you add a view. Note that cookies are set on the response of a call and it is not issued before coming to a view. For this reason, using a method call activity could be a bad approach to try this so a phase listener is better suited

  • Query about the ADF task flows call using URL

    ADF Version: 12.1.3 and 11.1.7

    We have a scenario where we want to implement a Home Application and product Application deployed as separate web applications.

    Now the House must have the ability to call the Application of product using call URL delimited task flow.

    My query is whether the return of a stubborn workflow will work in this scenario, because it works with the delimited call task normal flow.

    What are the other alternatives if it won't?

    Also anyone provides me with examples of applications for the above scenario.

I have the ViewObject for station 2, but I don't know where to put the code for "setNamedWhereClauseParam" and then run the query. Or in other words, how to pass the value of the key selected on station 1 station 2 as the parameter at the request of VO?

    Thank you

    Mike.

    Hello

    trains allow you to navigate between pages. So if there is a dependency between page1 and page2, where page 2 must have 1 page visited, so I think you should alow direct access to page 2. To answer your question

    -Create a file IMPL for the ViewObject to filter by the ViewCriteria
    -Create a public method that takes the input parameters required for bind variables
    -in the VOImpl define the VC and the bind varoables
    -run the VO
    -Create a public method (still on the VO2) ClientInterface
    -1 page write the parameters of the selected query in #{requestScope.param1},...
    -Drag and drop the client method as a method between page1 and page2 so the query call activity is performed
    -On the arguments to the method, use #{requestScope.param1} to read the search criteria in

  • ADF task flows finalizer

    Hello

    JDEV 11.1.2.0.0

    I need to call the method when the workflow stops. I can't use finalizer method because it cannot have PageDefinition (to contain the method and links the iterator)

    Is it possible that we can call iterator and the method links in the finalizer of workflow method?

    If drag us and drop method in the workflow, is possible we can ensure that method is called whenever get out us the workflow.

    Thank you

    JIT

    Hello

    the initializer and finalizer run while there is no available connection (the connection is not in scope) so it's impossible. So the question is what you call the method of through a binding. One option would be to access the BindingContext object to then access the domain controller you want to operate on and do the job manually that you would do through the link. Another option is to have an activity method before the return of the activity and give a PageDef file to this activity of the method to execute all what you need to do.

    As usual, usecase important

  • Why: Data control not extensible/empty - flow ADF based task entry on HT.

    Hi all

    I hope to create an ADF task flows based on a human task. I have an ADF stand-alone application in the ViewController which I want to create this workflow. The control of data entry resulting doesn't seem to be expandable.

    Questions
    1. When you create a Taskflow ADF based on a human task, should always be within a project in the same application as the SOA components?
    2. If not, is control of resulting data blank human task or not expandable because the xsd for the HT is based on the MDS? I have configured all MDS connections in my application.

    JDev: 11.1.1.4

    Thank you
    PP

    Hello

    Answers: -.

    1. No, it is not necessary that your ADF Taskflow based on human task should be in the same application where the SOA project. But this Taskflow-ADF deployment, to the SOA Project.You can add this project whenever you want to deploy.
    2. it may be the cause because of the Configuration of MDS.

    Do one thing, while creating the ADF Taskflow human task, you select the .task via the file system file not the MDS.
    If you select the. Your soa project task file, then it will ask you to name the Taskflow, just to name the taskflow you want and say ok.
    After you have created the taskflow, it will add a large number of xml files in your project and it will create a data control.

    It could be useful!

    Kind regards

  • Cannot invoke the stubborn task in adf application flow after deployment on stand-alone WSL

    Hello.

    We have developed application in jdeveloper 12.1.3 using ADF workflows and *.jsp (try us and *.jspx also) pages.

    Pls help me.

    We found a solution to the problem yourself.

    Our solution:

    On each page that uses the activity to call a workflow in the bindings, we added the executor of the ADF task flows Bindings type - taskFlow.

    The property is set (in my example):

    ID - taskFlowCall1

    taskFlowId - /WEB-INF/taskFlowCall1.xml#taskFlowCall1

    That's all.

  • Comments and questions about the mixture ADF Page flows with Trinidad UI

    Hi all

    I did a few tests to see how possible it is to use Trinity to the UI (for compatibility of this stinking IE 6) as well as the ADF Page flows / controller of the ADF. My question is whether there is a sustainable configuration from the point of view of Oracle. I did things to make it work and noted the following interesting behaviors (call anaomalies, if you wish):

    (1) addition of ADF Page Flow within the reach of the technology for a project automatically adds ADF Faces. If I try to eliminate ADF Faces of the scope of technology, it automatically deletes the flow of Page of ADF as well.

    (2) if I remove the ADF Faces DURATION 11 project library and create a page of trinidad (also set up the renderkit and as appropriate skin and remove a moment-false ServletADFFilter of web.xml) I get errors MDS when running the resulting page. I can't correct the error by removing the MDS libraries either - as soon as I put ADF Faces DURATION 11 library back, things are OK.

    (3) since I've faced ADF in my scope of technology, all newly created JSPX pages end up having af:document / af:form tags and have the namespaces implemented for ADF Faces. Not useful if I want only parts of Trinidad, but not a show-stopper, either.

    (4) an interesting thing that I have reported before... If I have the ADF Page library flow into my project and then configure navigation case in faces-config. XML (I know, wouldn't do that, just an observation, even if someone who has accidentally library ADF Page Flow in their project without any intention to use the ADF Page flows will find this very annoying to debug...), the first click of button that leads to the navigation works very well. All subsequent navigation requires two clicks on the link/button to trigger navigation. This behavior does not occur if you change the case of navigation to redirect = true.

    So, in summary, I seems to be the controller of flow/ADF Page ADF working with Trinidad, with a few minor problems of productivity due to an obvious requirement to have the Library Runtime of ADF Faces and the extent of technology ADF Faces included in my project. Now Oracle - is this going to be a sustainable configuration?

    I'd also appreciate comments, suggestions and comments from anyone else who has tried or is trying to use the ADF Page flows / ADF controller with a single user Trinity interface (well, in my case, I'm going to blur more using the tag af:template with components of the Trinity, but it's another whole story).

    Best,

    John

  • Task remote Flow and a shared library

    Hi Expert,

    Could you please tell me the difference between the remote call task flow and using the shared in performace propective library.

    If we use remote task flow, then there will be less dependecy from other project which has never want to use streams of task remotely... just give the URL and shared input parameter. I'm not sure how to call the remote task flow in a dynamic region. We do not want to use af:iframe as there is a lot of problem with leaking memory in the browser... Oracle does not recommend to use the iframe...

    Appreciate your help.

    Thank you

    Naresh Garg

    We already use af:iframe to call the remote task of flows in a couple of tab in a single Application. Somehow we get the problem by making the taskflow distance when visted repeatedly in different-2 tab in the fast. As directed by the team of Oracle's Support, do not use af:iframe to call the remote task flow.   So looking for solution to avoid the use of iFrame pages. as the dynamic region call...

    I just found a link to TaskFlow remote...

    Note: this distance task flow calls must be made from a delineated stream or unbounded task high on the page of the calling application. If called from a region (using the call parent activity) in a page, the State of the region is not recovered on workflow performance.

    The ADF developers have recently identified task flow remotely like an architectural model to partition their application of ADF in independently deployed Java EE applications. Although it looks like a desirable use of the remote task workflow capability, it is not possible to reach for as long that remote task flow return as a region of the ADF.

    Thank you Tim for quick response.
