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.

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"
                                           filename="Chiusura#{bindings.RegitrationNumber.inputValue}.pdf"
                                           method="#{pageFlowScope.JasperClient.reportPDFDownload}"/>
          </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?"
                 closeIconVisible="false" inlineStyle="width:500px;"
                 type="cancel">
        <af:outputText value="Siete proprio sicuri di voler chiudere questo veicolo?"
                       id="ot1" inlineStyle="width:500px; height:150.0px;"/>
        <f:facet name="buttonBar">
          <af:commandButton text="Conferma" id="cb1"
                            action="#{pageFlowScope.JasperClient.returnToSearch}">
            <af:fileDownloadActionListener contentType="application/pdf;charset=UTF-8"
                                           filename="Chiusura#{bindings.RegitrationNumber.inputValue}.pdf"
                                           method="#{pageFlowScope.JasperClient.reportPDFDownload}"/>
          </af:commandButton>
        </f:facet>
      </af:dialog>
    </af:popup>thanks!!!

Invoking remote java classes/methods

Hi,
I just wanted to ask for opinions and suggestions regarding my attempt to call a remote java class method using PL/SQL. I didn't want to load it in the database since the configurations for the java class were already set using Spring Integration. I just wanted to supply constructor arguments and run the method and then retrieve the result. Are there any good or easier ways on doing this?
Thanks in advance

Very curious Susan,
A server JVM might not want to host mobile code from other clients, not that it's unsafe, it's just that it allows clients to crash the server JVM at will. They should have it configured to automatically restart though.
Did they delete the java.rmi.* packages from the server JVM runtime? I don't understand why they'd do that.
If you can pry some reasons from them, I'd be very interested to hear them. Perhaps they just want more money, in order to allow you this privilige.

How to write javascript in java class method

Hi,
any one please resolved this,
i want to write javascript window closing code into java class method, in that method i want to write javascript code & wanted to call in jsf page on commandButton action event,
my code is below but it is not working properly
public void closeWindowClicked(ActionEvent event) {
          try
     FacesContext facesContext = FacesContext.getCurrentInstance();
     String javaScriptText = "window.close();";
     // Add the Javascript to the rendered page's header for immediate execution
     AddResource addResource = AddResourceFactory.getInstance(facesContext);
     addResource.addInlineScriptAtPosition(facesContext, AddResource.HEADER_BEGIN, javaScriptText);
catch(Exception e)
     System.out.println(""+e);
for calling into jsf code is below
<h:commandButton action="#{parentBean.closeWindowClicked}" value="OK" />
/*Note- i want to closed the window by caling method contain javascript only, i don't want any ajax code in method */
please any one can resolved this.
Thanks

/*Note- i want to closed the window by caling method contain javascript only, i
don't want any ajax code in method */ When the user presses your button, do your business logic and then send them to a page containing the following (note: untested code ahead):
<html>
<head>
    function onLoadHandler()
        window.close();
</head>
<body onload="onLoadHandler();">
    <p>Window closing....</p>
</body>
</html>

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.

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 ???
Edited by: ThDn on Jan 19, 2010 7:20 AM

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.

How to pass value from Javascript function to a Java class method

Hi All,
I want to pass a value, which I catch in a Javascript function to a method in a Java class. I have tried many combinations but it gives me error.
This is the way I am doing
function assignBill() {
proj = projPh.substring(0,indSlash);
<% myproject.getProj(" project_cd = '" + proj + "'");%>
proj is the variable which I want to pass to getProj methods.
If any one has done this, please let me know. Thanks for your help.

The only way to receive something from clients page is to submit it somehow: through a form or link, but the info has to make it back to the server obviously. I dont know how your app works, but you can use the the javascript -location.href- function(i think) to submit the var to the server and process it there.

Hi ,
In your java project frm jdev..right click and choose general and then choose deployment profiles and then choose Jar ..and then give some appropriate name(abc) and then click ok.
Then under resources file u get a abc.deploy file right click and say deploy to jar ..u will find the jar in that director.Now include this jar in your prjct libraries.
have a look at the link http://niallcblogs.blogspot.com/search/label/embedded%20Java

About control flow graph on java

i want to ask if there are some papers about control flow graph based on java or another object oriented language.
thanks

> i have search already on google. the problem is that i
didnt find anything usefull on this.
Once again, we have no idea what may or may not be useful to you or why the Google search results don't meet your satisfaction.
> i have to do a research on this subject.
Okay.
so i asked if u have already
found some papers about control flow graph based on
java or with some other object oriented language.
And the answer is, "Yes, I have found many". I found them easily with Google. Again, I have no idea which ones may or may not be useful to you, so it doesn't make much sense to just start posting a bunch of links only to have you say, "Nope, that's not what I'm looking for".
Keep researching, and best of luck.

Setting the message parameter in java class

Hi!
I have a resource bundle with a message that includes a parameter.
my.message.key=Part1 {0} Part2
I am able to fill this parameter when using this message in jspx page like:
<h:outputFormat value="#{res['my.message.key']}"
rendered="#{userInfo.authenticated}"
escape="false">
<f:param value="SomeValue"/>But when I try to get this message in a backing bean I just can't find a way to set this parameter value.
I'm using JSFUtils.getStringFromBundle for all my messages without parameters but can't find a way for messages with parameters. Can someone please tell me how do I set my parameter value (I know this can't be this difficult)?
Thanks!
BB

java.text.MessageFormat.format("Part1 {0} Part2", new Object[] { "SomeValue" }) will produce "Part1 SomeValue Part2".

Problems with data controls from java classes in JSF pages.

Hi! We have a problem in our Application that we are developing with JSF pages using Data Controls generated from facades java classes. When we running a page in debug mode and the page are loading, if we insert a breakpoint in the first line of method referenced in the data control, the execution enter two times in the method, and this is a problem for us. How to solve this?
We are using JDeveloper 11.1.1.2 with ADF faces.

You might need to play around with the refresh property of the action binding.
