Pop up not displaying in Task Flow application?

Hi...
I have a button which displays a popup on its click event.
When i converted this application to a task flow application this stopped working.
My button code :
FacesContext facesContext = FacesContext.getCurrentInstance();
ExtendedRenderKitService service =Service.getRenderKitService(facesContext,ExtendedRenderKitService.class);
service.addScript(facesContext,"var popup = AdfPage.PAGE.findComponent('pAddPopup'); popup.show();");
where pAddPopup is pop up window's id.

Application Module instance not found in task flow

Hi,
i am working on Oracle Jdeveloper 11g Release 1
I have created a bounded task flow for with following properties:
<transaction id="__14">
      <new-transaction/>
    </transaction>
    <data-control-scope id="__15">
      <shared/>
    </data-control-scope>
    <task-flow-reentry id="__13">
      <reentry-not-allowed/>
    </task-flow-reentry>I have declared a page flow scope bean in the task flow as:
<managed-bean id="__5">
      <managed-bean-name id="__6">trainBean</managed-bean-name>
      <managed-bean-class id="__8">oracle.sysman.core.gccompliance.view.library.rule.patchRule.PatchRuleTrainBean</managed-bean-class>
      <managed-bean-scope id="__7">pageFlow</managed-bean-scope>
    </managed-bean>but when i am trying to access the AM Impl instance from bean methos as below:
public static final String DATA_CONTROLLER = "ComplianceLibraryAMDataControl";
    public ComplianceLibraryAMImpl getDataControl() {
        DCBindingContainer bc =
            (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
        ApplicationModule am = bc.findDataControl(DATA_CONTROLLER).getApplicationModule();
        return (ComplianceLibraryAMImpl)am;
    }I am getting null pointer exception in ApplicationModule am = bc.findDataControl(DATA_CONTROLLER).getApplicationModule();
I am using the same way to get bean in other task flows as well , so i think the code to get bean is working correctly.
What am i missing in this?

thanks Puthanampatti ,
This is working and i am able to get AM instance from this , But i am not sure what is the difference between:
public ComplianceLibraryAMImpl getComplianceLibraryAM() {
ComplianceLibraryAMImpl am = (ComplianceLibraryAMImpl)ADFUtils.getApplicationModuleForDataControl("ComplianceLibraryAMDataControl");
return am;
Referred methods:
     * Get application module for an application module data control by name.
     * @param name application module data control name
     * @return ApplicationModule
    public static ApplicationModule getApplicationModuleForDataControl(String name)
        return (ApplicationModule) JSFUtils.resolveExpression("#{data." + name + ".dataProvider}");
     * Method for taking a reference to a JSF binding expression and returning
     * the matching object (or creating it).
     * @param expression EL expression
     * @return Managed object
    public static Object resolveExpression(String expression) {
        FacesContext facesContext = getFacesContext();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        ValueExpression valueExp =
            elFactory.createValueExpression(elContext, expression,
                                            Object.class);
        return valueExp.getValue(elContext);
    }And my previous approach:
    public ComplianceLibraryAMImpl getDataControl() {
                 DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
                 ApplicationModule am = bc.findDataControl(DATA_CONTROLLER).getApplicationModule();
                 return (ComplianceLibraryAMImpl)am;
    }Why am i not able to find my data control AM from Binding Container????

URL is not displayed in Work flow task of CRM UI and displayed in SOST/SWIA Tcode

Hi All,
I am trying to display the dynamic URL with short link in work flow task, the same got properly displayed in SOST/swia Tcode but not displayed in CRM UI under work list of user, may I know how to solve it?
code in work flow task under description is below :
/* <A HREF= www.google.com>Portal UWL</A>
Thanks,
VijHyd

Hi
You need to check with your CRM UI Consultant if HTML Tags are read and rendered.
Screens in SOST are rendered using HTML and hence you can see the links. You may face the same issue if you send to outlook and if outlook settings do not support HTML.... whereas it may work on Yahoo or Gmail as the web page will render using HTML.
So, check with your UI colleagues as to how HTML tags can be displayed correctly.

Button Actions are not working -invoking task flow from other project regio

Hi
I have a project using a mani.jspx file having a regions and the region is updated with different views based on a router condition in my bounded task flow. Everything working fine with in the project. I have a seperate project in my application having an index.jspx and region in it. I created the ADF lib jar file of the first project and imported to this project. I could invoke the task flow in the first project to the region in the index.jspx file in the seconed project.But none of the action managed bean method attached to the buttons in this view are working.The methods are not getting called on clicking on button and no error in the backend console of Integrated weblogic server.Any body can help what could be the issue ?
Thanks
Suneesh

The issue that is happening when I refreshed the region with task flow from the project I imported.If I load the taskflow from the imported project on first time rendering all my managed bean actions are executing but if I load a different flow initially and change the taskflow Id imported from other project none of the managed actions are working.
Thanks

Images do not display in Acmevideo sample application WebApp_8i.jws

Hello,
The JDeveloper 3 Acmevideo web application for Oracle8i is a nice-looking web application.
There is a syntax fault in the Java source files WebAppReports.java, WebApp.java of the JDeveloper 3 workspace WebApp_8i.jws
In the file acmevideo_deploy.properties I used something like this:
...imageURL=http://oashost:80/acmeimages/...
All occurrences of "/topmovie.gif", "/onoracle.gif","/filmsquare.gif" in the java source files WebAppReports.java, WebApp.java should be replaced by "topmovie.gif","onoracle.gif","filmsquare.gif". Otherwise these images will not display correctly in the web application.
I would like to know when Oracle will provide a tutorial on servlet deployment of the acmevideo web application to Oracle Application Server.
I understand that by providng a Java Webserver servlet deployment example the JDeveloper customer is not dependent on Oracle Application Server as web server.
How to deploy the acmevideo servlet to Oracle Application Server 4.0.8.1?
Thank you in advance for your reaction,
Erik Martens

Hi Erik,
For our next release, we are actually removing the Acme Video sample application. It will be replaced with the Web Auctions demo, which was used at the most recent Oracle Open World conference.
Instructions for deploying DBServlets to OAS 4.0.8.1 are included in the JDeveloper 3.0 release notes.

Images inside pop-ups not displaying correctly

I am generating a CHM using RoboHelp 10. I have certain pop-ups in some topics. These pop-ups contain screen shots. After generating the CHM, when I click the pop-ups to view the screen shots, they are not displayed correctly. That is, half of the image does not appear and there are no horizontal scroll bars either to scroll. This happens for pop-ups that are appear on the left side of a topic.The images inside pop-ups that appear to the right side of a topic appear fine when clicked.

Hi Rick,
Thank you for the response. Alas, updating the DHTML effects doesn't help. In the project that am working, I have used hyperlinks that are marked to be displayed as auto-sizing pop-ups.
I also tried editing the eHlpDhtm.js file as mentioned in the thread here, https://forums.adobe.com/thread/1297423#expires_in=86399993&token_type=bearer&access_token =eyJhbGciOiJSUzI1NiIsIng1dSI6I…. But that was of no avail either.
Do you have any other insights here?

Image UI element is not displayed in Abap webdynpro application

Hi Experts,
I need your advice on below issue.
I have created new ABAP Webdynpro application just to
display employee photo.
When loading the application, I generated a dynamic URL for
a image in webdynpro application path in cache to map to Image UI Element. It
is working well in DEV and QA environment. But it is not displaying when loaded
in PRD system.
Please suggest where to check the cache properties in system
in order to resolve this issue.
The user can access the application path, is there any chance for security issue in the same path?
I suspect the URL is cleared before user access it, can it be controlled via any config?
Looking forward for your valuable inputs.
Thanks,
Swetha

HI Swetha,
Maybe the image is not present in MIME repository for the PRD system.
Please check.

Hancila

Favicon.ico image does not display consistently for our application,

Hi,
We have configured a favicon.ico for our application as below code snippet and referring to the favicon.ico image correctly. The icon file is available in our war file post deployment. The problem is some times it displays correctly and sometimes it does not display correctly.
<af:outputText value="<link rel='SHORTCUT ICON' href='#{facesContext.externalContext.requestContextPath}/images/favicon.ico'/>" id="favicon" escape="false"/>
Can anyone point to any issue related to browser caching or application server caching and any possible fix to this intermittent behavior.
regards,
Chandra.

Browser caching might be a problem, but we can't help as it is a browser issue. All I can say is to clear the browser cache and see if the problem can be reproduced. If yes it doesn't look like a browser problem. Then you have to check if you are connection via proxy which might cache images too. Ask your network admin for help then.
Do you see this problem only with one browser? Have you check other browsers?

SAP EXPRESS Pop-up not displaying

Hello Workflow experts,
My workflow needs to display a pop-up when it arrives in the workflow inbox. I researched the site and found references to setting the priority to 1 in the activity step. This I understood to mean that I needed to go to the task in the activity step and under the tab-strip OTHER change the priority.
However this does not workis there something that I am missing here
David.S.Dittmer

You can find Program Exits tab in step type Activity and most other step types in the Workflow Builder. Yes, you will have to insert code.
Refer the help page
http://help.sap.com/saphelp_nw2004s/helpdata/en/1a/6b023c3f6aaf08e10000000a11402f/content.htm

I have never worked with them. This ABAP OO class is an example of a program exit CL_SWH_WORKITEM_EXIT.
As a standard you can send Mails that pop up a dialog informing the user that they have got an email in their SAP Business Workplace. For this create a Send Mail step and check the Express option. I think this is not available as a standard for tasks.
Hope this helps.
Thanks,

Euro symbol not displayed/stored correctly when Application Server on AIX

Hi,
Up till now we have an BC4J/ServiceFile/UIX application (generated with JHeadstart)running on Windows OS (Application Server and Database).
The customer has decided to move the Application Server (10g) to an AIX machine.
When testing the application we find:
1) Euro symbol () is displayed en stored correctly when stored in varchar2 db-columns
2) The Euro symbol is not stored correctly when stored within a CLOB db-column AND when the AS runs on an AIX.
When the Application Server runs on a Windows-platform the euro symbol is displayed and stored correctly.
Our first guess was some NLS_LANG configuration problems on the AIX-machine. We tried however to set the NLS-LANG to "DUTCH_THE NETHERLANDS.WE8MSWIN1252". This had no visible effect.
Are there other (if any) NLS-settings which influence the way the CLOB-columns are dealt with?
When connecting to the same database from a Windows-Application Server no problems occur, thus showing that the problem is AS/OS specific.....
Our guess is that is related to BC4J and how BC4J communicates with the database.
Is this problem a known bug/issue?
Any ideas how to solve this problem?
We are using JDeveloper 9.0.3.1 (build 1107), Business Components Version is 9.0.3.10.62
Thanks,
Anthonie

Sorry, I'm having difficulty understanding what's happening here. Let me see if I get it.
You have an application that stores the euro symbol in a CLOB. When the server that handles this application is on AIX, the euro is not properly displayed in the client. When the server is on Windows, it displays properly.
Is that the issue? If so, it could be a number of things, but it's probably related to the character set differences between the two database servers.
Have you been able to reproduce this without using Business Components?

Report does not display data in Oracle Applications

I created a custom report and registered the same under Oracle Order Entry. The report uses 1 parameter and whereas everything is registered in Oracle apps. correctly, the report draws a blank upon completion. The only visible thing is the header part.
This report though works fine if run directly from Reports Designer.
Anybody know what specific setting (if required) needs to be made in Oracle Applications? Further in order that you can know the picture, whatever is enclosed in the Repeating Frame does not show up in App. but as pointed earlier works just fine from Reports Designer.
Any help would be greatly appreciated.

I am using a browser (FireFox v2) based InfoView so I guess it is the DHTML viewer.
On the server it is java (Tomcat). The report uses a custom driver (crdb_ado).
Currently all the servers (RAS, page, cache etc) are running under LocalSystem account. I don't understand what a domain account is, is it administrator?
The interesting part is, I was able to upload and run 8 other reports before I experienced this problem. Have I hit some limit?
I appreciate your help. Please share any other ideas/insights on this issue.

How to change default ports for task flow application?

I deploy a task form with the following hwtaskflow.xml information:
<?xml version = '1.0' encoding = 'UTF-8'?>
<hwTaskFlows xmlns="http://xmlns.oracle.com/bpel/workflow/hwTaskFlowProperties">
<ApplicationName>worklist</ApplicationName>
<LookupType>LOCAL</LookupType>
<TaskFlowDeploy>false</TaskFlowDeploy>
<TaskFlowServer>
*<hostName/>*
*<httpPort/>*
*<httpsPort/>*
</TaskFlowServer>
<hwTaskFlow>
<WorkflowName>ApproverHumanTask</WorkflowName>
<TaskDefinitionNamespace>http://xmlns.oracle.com/MyApp/MyComposite/MyTask</TaskDefinitionNamespace>
<TaskFlowId>MyTask_TaskFlow</TaskFlowId>
<TaskFlowFileName>WEB-INF/MyTask_TaskFlow.xml</TaskFlowFileName>
</hwTaskFlow>
</hwTaskFlows>
When I deploy the form then check the task URI in EM I see
Host name: server host name
HTTP port: 80
HTTPS port: 443
I know I can override these ports in the hwtaskflow but what if I want HTTPS port left blank? We don't have HTTPS active on our server. Another server in our environment only populates the HTTP port (HTTPS port is left blank) but I'm puzzled why the different behavior.
Can anyone tell me either how to specify a "blank" HTTPS port in the hwtaskflow or, preferably, how to change the server configuration so that HTTPS port is not filled in when I deploy the task form? We are wanting a completely automated deployment and presently we have to manually remove the HTTPS port via EM after deploying. Argh!

Jon,
May be you already figured out the solution nevertheless i will answer your questions.
1. Turning off the https port - give value as 0 for httpsPort in your hwtaskflow.xml.
Second reason why your custom hwtaskflow is not getting picked up is you have set the TaskFlowDeploy as false.
If you set this as true , and specify your cluster address you should be all set.
for eg : - your cluster host address is somename.cluster.com with only http configured at port 80 lets assume.
Then your hwtaskflow should look like this
<?xml version = '1.0' encoding = 'UTF-8'?>
<hwTaskFlows xmlns="http://xmlns.oracle.com/bpel/workflow/hwTaskFlowProperties">
<ApplicationName>worklist</ApplicationName>
<LookupType>LOCAL</LookupType>
<TaskFlowDeploy>true</TaskFlowDeploy>
<TaskFlowServer>
<hostName>somename.cluster.com</hostName>
<httpPort>80</httpPort>
<httpsPort>0</httpsPort>
</TaskFlowServer>
<hwTaskFlow>
<WorkflowName>LeaveRequestTask</WorkflowName>
<TaskDefinitionNamespace>http://xmlns.oracle.com/BuildApplication/BuildProject/LeaveRequestTask</TaskDefinitionNamespace>
<TaskFlowId>LeaveRequestTask_TaskFlow</TaskFlowId>
<TaskFlowFileName>WEB-INF/LeaveRequestTask_TaskFlow.xml</TaskFlowFileName>
</hwTaskFlow>
</hwTaskFlows>
This will automatically pick up the values on deployment , other play you can configure this is in your em console as well.
