Passing parameters between form portlets on two different pages ...

Here is a brief summary of our problem.
We have one master form and a detail form which are published as portlets and placed in two different pages.
Now i want to pass parameters from master form portlet resides on one page to detail form portlet resides on another page.
Say for example, when i invoke master form (created based on demo DEPT table), enter values on fields then invoke another page
on which the second form portlet (say form based on EMP demo table) resides. Now i want to pass deptno to second form and
get displayed in deptno field of second form.
I was looking at the following posting, but how to do this when forms are published as portlets and placed on two different pages ?
http://forums.oracle.com/forums/message.jsp?id=997683
Customer actually want to pass a parameter from master form to 5 detail form portlets resides on different pages.
This is bit urgent as it is the only problem stopping the customer go live.
Thanks in advance.

Please refer to post Re: session state security
It tells you how to populate a form portlet in a page by clicking on a link in a report portlet.
You can use the wwsto_api_session objects to store data submitted by the master and let the detail form pick it up and proceed with the query.

Passing Parameters between 2 Portlets on 1 Page

Hi,
I'm new to this portlet stuff and I might miss something important, but:
I "just" want to send parameters from one form on one Page to a portlet on the same page...
PassAllParameters is already set to true...
I also have read the "Primer" and the "Adding Parameters and Events to Portlets", after giving up to do this my own, I just copied and pasted the Name/Age Form JSP (nearly... I've made Java out of it...) as my DataProvider Portlet and copied and pasted the "Generic Public Parameter Receiving Portlet" as my DataReceiver Portlet... the Event and Parameter Tags are NOT missing in the provider.xml... but even after pressing submit there are no parameters at all avaible for the "receiving Portlet"!!!
PLEASE can someone tell me what I am doing wrong?!?!?!?

Hi friends,
I worked with the application which is in
http://server:port/jpdk/providers/event. is working fine with passing parameters to another page.
Also I create my own application which is working fine if i have the 2 portlets in the same page.
But it is not working with portlets in different page. On clicking the link it is not going to the another page. Hereby i give the required codes.
portletpass.jsp:
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
String eventSubmit = EventUtils.eventName("submit");
String eventParamsno = EventUtils.eventParameter("sno");
String strsno="50" ;
NameValuePair[] linkParams = new NameValuePair[2];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, eventSubmit), "");
linkParams[1] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, eventParamsno),strsno);
<a href="<%=PortletRendererUtil.constructLink(prr,
prr.getRenderContext().getEventURL(), linkParams, true, true)%>"><%= strtitle %>
</a>
provider.xml of portletpass.jsp:
<event class="oracle.portal.provider.v2.DefaultEventDefinition">
<name>submit</name>
<parameter class="oracle.portal.provider.v2.DefaultParameterDefinition">
<name>sno</name>
<displayName>sno</displayName>
</parameter>
</event>
portletreceive.jsp:
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
//      String snosp = "sno", snorec="" ;
//     String values = prr.getParameter("sno") -------returns null
     String values = prr.getParameter("_page_url");
     String snorec = values.substring(values.lastIndexOf("sno=")+4) ;
     out.println(snorec); // here i get the required value
provider.xml of portletreceive.jsp:
<inputParameter class="oracle.portal.provider.v2.DefaultParameterDefinition">
<name>sno</name>
<displayName>Input Parameter #1</displayName>
</inputParameter>
Also i did the necessary changes in parameters and events tab as well.
I cant sorted out what is the mistake i did.
The scenario i need is on clicking the link it should display the details in a new page.
Can anybody please help me.
Thanks in advance

Pass parameters between forms using a menu

I use a menu to switch forms. However, I have problems to pass paramenters between the froms.
Any suggestions ? Thanks.

There are 2 means:
1. The most simple to code is to use global vars. Still, you may get into some trouble managing them (erasing them when you no longer need them).
2. Use parameter lists. RTM about that. It's a bit complicated, but feisable, allowing to pass params whe using open_form or run_product (run_report).
One more thing: when referencing forms items from menu code you have to use name_in(), and for assigning values to form-items using menu code you have to use copy().

PASS PARAMETERS BETWEEN FORM-- REPORT PORTLET

I have to develop a page. On the left handside of the page preferably a portlet there will be a form where user will enter all the parameters. Based on the parameters a report has to be generated on the right hand side of the page which again can preferably be a report portlet.
Could anyone give me directions as to how to proceed.
Eg: user selects a deptno on the parameter form on the left side, the right hand side should display report of all the employees in that dept.
Its similar to frame driver concept but this application prohibits use of Frame drivers.
Thanks

Passing Parameters between Java Portlets

i hava java portlet and it does a search... the search result appears within the portlet region.... but i want to be able to click on the search button and take it to another portal page and have a portlet that contains the result of the porltet... how is that acheivable...

Well i've done this with java pdk portlets, but I guess the principle is the same everywhere.
Where are 2 types of parameters, qualified and unqualified ones. In your case you have to
use unqualified ones, so that your other portlet can read a parameter which is set by your search portlet.
Also add <passAllUrlParams>true</passAllUrlParams> to your provider.xml, inside a portlet tagof the result portlet, so yo are able to read unqualified params aswell.
Othee options are using sessions or a persistant datastore, eg database

Sharing parameters between 2 portlets

I have two seperate java applications, both of which have been turned into portlets with their own provider.
I need to pass parameters between the portlets and am trying to work out the best / most secure way to do this.
I know that if both portlets were in the same provider they could share providersession information. I could do this if i could change one of the provider files to link to a portlet in another jdeveloper application. I believe its not possible to have more then one portlet in a provider if the code for the second portlet is comming from a seperate jdeveloper application ??
I could also pass parameters through portlet / page parameters. The problem is that i don't want these parameters to appear on the URL. Am I correct in assuming that this type of parameter passing between portlets always means the parameter appears on the URL.
I heard of the java object cache as a method, but don't know where to start with this !!
Dows anyone a solution , to what must be a common problem ?

Hi Frewin,
Why cant you have both the portlets in the same JDeveloper project? You can have as many portlets as you wish to have within a single provider.
Frankly, you dont really need to rely only on jdeveloper :-) ...

How to pass Parameters between two forms

im trying to do this but i could not find any way for this.
can any one help me how can i pass parameters between two forms
in forms4.5. any help will be appreciated
thanks.

Global variables can be used, but you can do what the online help
says ...
Parameters are passed to called forms by means of a parameter
list. A parameter list is a named programmatic construct that is
simply a list of parameter names (called keys) and their values.
You can pass parameter values to forms invoked by the built-in
subprograms CALL_FORM, OPEN_FORM, and NEW_FORM. In addition, you
can pass parameter values to other Oracle tools with the
RUN_PRODUCT procedure.
A parameter you include in a parameter list can be either a text
parameter or a data parameter. The parameter type determines how
its value is interpreted.
Text Parameters The value of a text parameter being passed to a
called product is a CHAR string that can represent the following:
n a user-defined form parameter defined in a form invoked
by the CALL_FORM, OPEN_FORM, or NEW_FORM built-in subprograms
n a command line or user-defined parameter for a product
invoked with the RUN_PRODUCT built-in subprogram
Data Parameters The value of a data parameter being passed to a
called product is always the name of a record group defined in
the current form. (A record group is a data structure that
stores records derived from a query or through programmatic
assignment.) Data parameters are used to pass data to products
invoked with the RUN_PRODUCT built-in subprogram. You cannot
pass data parameters to forms.
The following table shows the structure of a parameter list that
contains four parameters:
Key Paramtype Value
CITY Text_Parameter 'BOGOTA'
CATEGORY Text_Parameter 'EXPORTS'
MULTIPLIER Text_Parameter '.0275'
NEW_DATA Data_Parameter 'RECORD_GROUP8'

Passing Parameters between Portlets or pages

Hi,
How can we pass the data from a Portlet in one page to another Portlet in a different Page??
Requirement: I want a portlet which should take some parameters(basically a form),On submit should process the parameters and should forward the result to a Portlet in another page.
Regards
Yash

Yash,
You could use session variables to save information that can be used during the browser session. Example would be the form asks a user for their nickname. The user types in his nickname and hits the submit button. The form will then save the info in a session variable. Then any other portlet can open that session variable and get the info and use that info. Now if the browser is closed, the info in the session variable is lost. Check out this link:

OBIEE 11G - Issue passing parameters between two reports

Hi folks,
I am struggling to pass parameters between two reports in OBIEE 11G.
My first report contains the following columns: Rolling Year Type (VCHAR), Year(VCHAR), Month(VCHAR), Cost(Double).
My second report contains the following columns: Rolling Year Type(VCHAR), Year(VCHAR), Month(VCHAR), Category(VCHAR), Cost(Double).
My requirement is to pass the Rolling Year Type, Year and Month values from report 1 to report 2.
On the Month column properties of report 1, I have created an Action Link called 'Drill to Category'. I have clicked on 'Navigate to BI Content' and selected Report 2.
Then on Report 2, I have included three filters: Rolling Year Type is prompted, Year is prompted, Month is promted.
When I run the report I always get the following error:
The specified criteria didn't result in any data. This is often caused by applying filters and/or selections that are too restrictive or that contain incorrect values. Please check your Analysis Filters and try again. The filters currently being applied are shown below.
When I check the cursor cache, the filter values are correct. Does anybody have any idea why Report 2 does not display?
When I remove the Month filter, the report works correctly.
I have since changed the third filter to be Month No and although Report 2 does display, it does not pick up the filter on the Month No.
I initially thought this may have been a caching issue and so I have disabled BI Server Cache but this does not fix my problem.
This was never an issue on OBIEE 10G as I found it very easy to navigate between two requests.
Has anyone else experienced problems with passing parameters between two request in 11G?
Any help appreciated.
Thanks
Gavin

Hi,
I once tried this kind of requirement(with dashboard prompts though) and hit at similar issue. I later found out that the problem is with the space in the parameter values. Can you please let me know, if the same is the case with you?
Suppose the parameter passed is "Jan 2010", but the report on the destination takes the value as "Jan" & "2010". Yes, it kind of split the parameter value to two based on space. I think we can notice the filters the destination report got, by enabling filter view.
In this case, since you pass only value at a time, could you try placing the parameter value anyway in double quotes? I think the Server then will understand it as one value.
Thank you,
Dhar

Passing parameters between views in different Web Dynpro applications

Passing parameters between portlets (PL/SQL PDK)

I'm new to the PDK, so forgive me if this is a dumb question. I need to develop a portal page containing a single search portlet, and then many other associated portlets which bring back various bits of data based on the result of the search.
Is it possible to drive the content of other portlets on the same page by passing values from one to another and refreshing the whole page?
null

Neil,
You can definitely pass parameters from one portlet to another in PL/SQL and we actually have a sample that you can take a look at. In the PDK, download the Parameter passing and CSS Example Provider sample. http://technet.oracle.com/products/iportal/files/pdkjan/index.html
Click on PL/SQL
One of the portlets demonstrates how to pass parameters to one portlet or all portlets on a page.
Hope this helps,
Sue

Trying to pass parameters between GUI classes and methods

Hi All.
I have been working on a rather large final year project in college and it is getting close to the deadline. It looks as though I need to "tidy up" my code as it contains too many static methods, variables and other bad programming habits. My package consists of many different GUI's and classes. Up until now I have been calling different GUI's with guiName.NameOfMethod. I have been told this is bad practice so I am trying to fix this. Also instead of passing parameters correctly I have been creating static variables in my main class and using them. So for example if one class needed to pass a variable to the other I would first myGlobalVariable = X; in the first class. And then the second class can use this. This is also bad, right?
So I guess im really just looking for a good example or tutorial on how to pass parameters between classes and methods, GUI if possible. Here is an example of how my GUI classes look:
public class anotherGUI extends JFrame implements ActionListener {
        private JTextField a, b, c;
        private JButton button1, button2;
        JPanel p, p1;
        public anotherGUI() {
            LayOutAnotherGUI();
            setLocationRelativeTo(DnDMain.pictureArray[a]);
            setTitle("Example");
            setVisible(true);
            pack();
        private void LayOutAnotherGUI(int c) {
     //GUI is layed out here
        public void actionPerformed(ActionEvent e) {
            Object source = e.getSource();
            if (source == submit)
                clickOK();
        public void clickOK(){
            //Here is where I have been accessing and modifying static global variables. (But this needs to change).
public void showanotherGUI() {
        new anotherGUI();
}This is more or less how I have been going about creating my GUI's. These are used as pop ups. The user enters a value and then it is closed.
To be honest I have been able to pass a variable correctly from one class to a GUI class but I have still having difficulty. For example in my code above I can pass the variable into this class but I cannot pass it into clickOK(). An this is where it is needed.
Can anyone please help?
I hope I have explained my problem well.
Thanks in advance.

I dont think that is what I need. An example of what I do in my program is:
I have a main GUI with an array of images. There are a number of other small GUI's that appear for certain functions when the user clicks on an image or does some other function. I am trying to pass a value into the GUI class that is used for the smaller "pop up" GUI. So lets say the user has clicked the image in array[12]. Then a GUI is displayed. I need to pass the integer 12 into this class.
Thanks.

How to pass parameters between main and sub vi during parallel execution using the VI server technique?

Hello All,
I am working with the following example (from previous postings on this
board) that demonstrates how to run a sub vi in parallel with the main
vi. I'd like to pass parameters between the main and sub such as
the control (delay) and indicator (value) parameters of my subvi
example. Does any one know how to do this? Parallel
execution is important for me, I cannot just paste the subvi icon into
my main diagram (two nested while loops...)
Many thanks,
Luis

Luis, you can use the VI Server methods 'Set Control Value' and 'Get Control Value', as demonstrated in the attached examples.
