Using Portal Forms

Hi, i'm Pedro
I have a problem about using forms. How can i call a field of a based table form.
For example using forms 6i, i use
:<block>.<field name> to access field, and using Portal how can i do the same??
The purpose to do this is to customize some events to do adicional funcions like validations
Pedro Ribeiro

Pedro,
This is a tough one. You may want to try the Forms forum or 9iAs Portal forum to see if anyone else has tried this. This forum is for questions directly related to the Oracle Portal Development kit.
thanks,
Sue

Auto querying using Portal form?

A friend of mine has a report that is linked to a form, where users can edit the data. The value from the report is passed to the report, no problem, but the user must manaully click on the query button to display the information. My question is: how can I make the report query on the passed value without having to manually click the "query" button? Thanks
Rich

Richard,
Please take a look at our FAQ:
http://otn.oracle.com/products/iportal/htdocs/portal_faq.htm
"Building Applications" section has several examples of links how to call a form in "auto-query" mode.

PORTAL FORMS

Hi ,
When must I use PDK when developing an application using portal forms ?
Do I need to use PDK for customized error handling ?
If I want to use pl/sql via triggers to validate fields, how do I attach the trigger/s to the portal form fields?
Thanks,
Sonal.

Hi Sonal,
You will find the pl/sql button handlers for a button.
Click on a link for a form item (say, INSERT_TOP), which is of type button, in the left frame.
Go down in the right frame, and you will find the text area to write your javascript handler and pl/sql code for the button handler.

How to use javascript to access item VALUES on a portal form

Hi,
I want to pick up VALUE of an item on a portal form from the on click event of the save button. I know there is a way to acces the item name and assign a value to that item. For example,
setItemValue(this.form,'UNIT_NAME', this.value)
If I use this line of code then I get the value of the save button because I put this line of code in the on click event of the save button. Please help.
Monique

You can get hold of any field on your form as follows:
document.forms[0].elements['<form>.DEFAULT.<field>.01']
So for example to get (or set) a value in my form I have:
document.forms[0].elements['REQUESTFRMEU.DEFAULT.BUS_OBJ.01'].value
Note that setting a value of a field with Javascript on the Insert button's onclick event will not result in the new value being sent to the DB. I think it has to do with the values being set into a session object of sort and the DB gets updated from these values and when you update the field with JS it does not update thesee session values. If you set the value somewhere else (e.g. another event handler before the Insert button is clicked) you should be OK.
Cheers.

I am using the portal forms and reports in the locally built providers and

need to find a way to use a dynamic LOV for select and then submit retrieve the data in a report. Anu help would be greatly appreciated.

If you accept a very basic form parameter, you can use the form automatically generated by any report component. Before, you have to create dynamic LOVs and map these LOVs to your parameters in report definition.
If you need a sophisticated parameters form (saying a "nice" form), you have to design either a regular form component (based on a dummy procedure which will call the report you made with the parameters), or a dynamic page which will call the same report. In this last case, (the better choice in my opinion) , you can embedd calls to package utility(portal.wwv_ui_lovf.show) which generates dynamic LOVs, inside the <oracle> tag.

Default value of combobox using dynamic LOV in Oracle Portal form

We are trying to specify the deafult value of a combobox on a form that derives it options from a dynamic LOV. The option value is a number and the display is text.
E.g.
<Option value="1">Books
<Option value="2">CDs
We have tried various ways of setting the default option to be selected on the Combobox. First, we tried using a sql query to return a number from a table (sql query returns number -> in the default value type field). Next, we tried to use a constant number (default value: 2, default value type: constant). In neither case, did the Oracle Portal form pre-select our default choice in the drop-down list.
Any suggestions? I browsed the other forum articles on this topic and noticed several folks believed it was a bug in Portal. We are using Portal version 3.0.9 (latest App Server for the Ebusiness Suite). Thanks in advance.

You can manually add the select list (or for that matter anything else) to a wizard created form. If the select list is for an existing item, simply change the "Display As" setting from Text to a Select List based on the LOV you create. Any changes made will then be applied by the update process.
cheers,
Ron

Is there a problem using popup LOVs in a portal form with a bind variable?

I have a portal form with 2 LOVs. The second LOV is a dependent LOV whose bind variable can be NULL. I have read Note 263923.1, "How To Create Dependent Lovs In Forms", and my form works as long as I use combo boxes to display the LOVs. I need to use popups so the user can search the LOVs as they are quite lengthy. Plus I want to be able to pick a value from my second LOV without selecting a value from the first LOV -- hence, my bind variable can be null and that is where my problem lies. As long as I select a value from the first LOV, the second LOV popup will work. If I click on the icon to display the second LOV without pre-selected a value from the first LOV, I get the following error:
POPUP LOV ERROR:
LOV: "9A17692880B6B8509F514F5B9CA9EC808DD403218B3CF19A33C04CD1FAB0ADE17ADC33E6B67998A933357CE5264D204E"
Parse Message: Parse as pre-set global: "TORE".
Find Message: LOV is of type DYNAMIC (LOV based on SQL query).
Query: "SELECT ...."
wwv_bind.prepare_bind: ORA-01403: no data found
My form is based on a table with a custom layout. The sql for the second LOV is similar to: SELECT ENAME, EMPNO FROM SCOTT.EMP WHERE (DEPTNO = :DEPT AND :DEPT IS NOT NULL) OR :DEPT IS NULL.
Thanks in advance for any help,
Carol

Don't use EPS any more! It does not support transparency nor color management.
If you save vector files from Illustrator, use AI with PDF compatiblity.
If you save image files from Photoshop, use PSD.
If you save image files combined with vector forms and/or text from Photoshop, use PDP which is a Photoshop PDF.
For vectors from Illustrator use CMYK files.
For images use RGB, conversion to CMYK should never done before PDF export, better, if the printer allows it, is to export a PDF with live transparency as it is PDF/X-4
If the printer requires a PDF with CMYK only export a PDF/X-1a.

Use Custom Button to go to another portal form

Hi,
I created a custom button, and in the PL/SQL handle, I put in the code to redirect the url to another portal form/report. When I run the form and press the custom button, it does not go to the other form, it remains on the same form that I started with. Why?
I can put the same piece of code in advance PL/SQL => After displaying the page, draw a html button to do the same task. It will work for me when I press the button (i.e. go to another form). So, how come I cannot do the same thing using Custom button?
Thanks;
Kelly.

Kelly,
The reason you don't see the next form because our module subsystem has a set of rules when to redirect and when not. However, there is an "internal" function which you can call from your custom button code to get this effect:
PORTAL30.wwa_app_module.set_target('http://www.yahoo.com','CALL');
Please note this is an internal function and may change at any time.
Thanks,
Dmitry

How to get HTML form name for use in Portal Form's custom layout?

I want to add a date selector to a Portal Form but the NAME attribute of the FORM HTML tag is dynamic.
To add a calendar icon that opens a date selector, I add the following tags to the custom layout after the date form field:
<img src="/images/calendar.gif" height="16" width="16" border="0">
The <form field name> is static, but the <form name> appears to be dynamic (e.g. WWVM3115, WWVM3116, WWVM3117, ...).
The custom layout uses substitution variables for the form fields and labels. Is there a substitution variable for the form name?

Here's the javascript function someone recommended several years ago (on an oracle portal forum) that I've used successfully to reference fields in non-portlet portal forms:
function findItem(pFieldName) {
var vFormElements = document.forms[0].elements;
for(var i = 0; i < vFormElements.length; i++) {
if (vFormElements.name.indexOf("."+pFieldName+".") > -1) return i;
document.write(i);
return -1;
You can then reference the portal form field name using the column/field name only:
document.forms[0].elements[(findItem('COLUMN_NAME_HERE'))]

Problems in using using a calendar to pick up a date in portal form

Hello:
I met some problems in using using a calendar to pick up a date in portal form.
I created a form using "custom layout"
Using Scott/Tiger, emp table HIREDATE put the following anchor next to it in the body text field
<<img src="/images/calendar.gif" width=24 height=22 border=0>
Then, I put the source tag in the header section
<script language="JavaScript1.1" src="/images/date-picker.js"></script> in the Header Text of the Form Text part.
However, for some reasons, after I pciked the date in the calendar,the field in the form could not be updated.
Your help would be highly appreciated.
Wei

I just fixed the bug. The data pickup calendar is working now.
The reason is that:
when oracle portal generates a portal form based on a table, the element in the generated form is defined by: [Form Name].[element name].[index#].
e.g.
<INPUT TYPE="BUTTON" NAME="FORM_AREA.DEFAULT.QUERY_TOP.01" VALUE="Query" onClick=" do_event(this.form,this.name,1,'ON_CLICK','');">
The "FORM_AREA.DEFAULT.QUERY_TOP.01" means: A input text box "QUERY_TOP" with index "01" in the form "FORM_AREA" which is located in the "DEFAULT" block.
The problem of my previous codes is that: Javascript could not access the elements on the parent widnow by name for those elements whose names have more than 1 "." sign e.g. "FORM_AREA.DEFAULT.QUERY_TOP.01". So, I accessed them by their locations in the DOM hierarchy. It works now.
e.g.
<a href="javascript:show_calendar('forms[0.elements[23');" onmouseover="window.status='Click to open an Wei's calendar'; return true;" onmouseout="window.status='';return true;">
<img src="/images/calendar.gif" width=24 height=22 border=0>
</a>

How can I uninstall a damaged installation of Fusion - PFRD 11.1.1.6.0 - Oracle Portal, Forms, Reports and Discoverer

Hello,
I am upgrading EBS 11i to 12i, Discoverer 4 to 11. After completing ebs installation and upgrade successfully, I am now working on the Oracle Fusion piece of the upgrade.
I have installed
1. JDK
2. Repository Creation Utility - RCU (schema)
3. Weblogic - WLS 10.3.6
4. Oracle Fusion - Discoverer 11g Release 1 Patchset 1 11.1.1.2.0 PFRD
5. Oracle Portal, Forms, Reports and Discoverer 11g Patchset 11.1.1.6.0 - Patchset 13517084
6. Executed config.sh and it failed with but continued.
During the Configuration of Oracle Fusion with config.sh there was failure at with "fails at creating data sources" and accidentally proceeded and all seem to go well until after shutting down the servers when Weblogic Managed Server is unable to start.
The start log indicated: "weblogic.store.PersistentStoreFatalException: [Store:280105]The persistent file store "_WLS_WLS_DISCO" cannot open file _WLS_WLS_DISCO000000.DAT." and I have been unable to find a solution for this error?
See log file error at https://dl.dropboxusercontent.com/u/15497130/oracle/ebs11/startManagedWebLogic.sh_nohup.out
If re-installation is my only option, then what are the steps to uninstall, and which components do I have to uninstall given that I had upgraded all the schemas involved?
Mathias

Hey,
You can always change the JDBC datasources in the Weblogic admin console . but have you recorded what is the specific error you got during the datasources creation .
I prefer...create a new user , give him sysdba privillages . Start RCU and create the DEV_DISCOVERER , DEV_DISCOVERER_PS schemas (prefix is your choice)
The Admin server will start . so go to admin console .
click services -> Data Sources
Check the data sources you have . edit each datasource and update the connection pool information .
after this you can start the Managed server WLS_DISCO
i believe this will solve this .........
if you still get issue again . you can try the link Using the WebLogic Persistent Store
Thanks

How can I set the focus to a field on a Portal form?

Can anyone tell me if it is possible to set the focus to a particular field on a form which was created in Portal and is based on a PL/SQL procedure?
The form contains a mixture of field types and also takes parameters from another form and displyas them.
I have managed to set the focus on a form which is defined dirdctly in a PL/SQL procedure, using Javascript, but this doesn't seem to work for a Portal form.

Hi,
look at the discussion on May 25:th 2001, subject "How to get the cursor into a specific field", it might give you an idea.
To give you some hint right now:
In the "Additional PL/SQL Code" tab, "Before displaying the page", add following code:
htp.p('<BODY onLoad="document.forms[0].elements[6].focus();">');
forms[0] if you only have 1 form, and elements[the number of the item you want to be in focus]
I hope this could help you

Install and config issues with Oracle Portal, Forms, Reports and Discoverer

For a while now I've been struggling with migrating a testing database to a newer version.
And right now I'm pretty much stuck at trying to configure Oracle Portal, Forms Reports and Discoverer
What I've got:
Windows server 2008 R2 64bit
Oracle 11g database
Java 6u27 64bit
JDK 1.6 64bit (using this after 1.7 ended up throwing out bugs while trying to start a weblogic server)
JDK 1.7 64bit
Weblogic 10.3.5 (or so i think - I've installed from the wls1035_generic.jar from the oracle website)
PFRD 11.1.1.2 with 11.1.1.3 installed over it, installed without config
and a hanging up configuration
Basically I've been trying to install PFRD (only forms, reports and enterprise manager from it actually) but it kept failing once it got to the configuration stage, so I installed without config, applied 11.1.1.3 and now trying to run the config manually with the good old \bin\config.bat
Result - the config froze for approx.18 hours then failed
There isn't much useful info I could deduct from the logs, mostly just says one or more configuration parts failed. At one place it mentions trying to set up a domain and starting up an adminserver for it - and apparently that's where it hangs up and finally times out and fails.
I'm a little clueless what to do about it as the logs don't say anything else of use I could understand. Any ideas there?

Trying the step by step, the only difference between that and what i do seems to be the file copying (which I can't do - there is no windows\extra\ directory anywhere, the files mentionned seem to already be on their places and either only there, or exactly the same) and clistering
So far the news ain't good - the config process hangs on creating domain ->Step Creating Domain started
It isn't frozen per se - the process doesn't use up any processor time, memory consumption within bounds, it reacts to button clicks and all..it just doesn't do anything concerning the said domain
the last thing the .out file shows:
Creating a new AdminServer Object ...
AdminServer port is 7002
Starting the domain ...

I'm kinda paranoid about the double backslash in the dll path, but other than that no clue as to why the domain doesn't set up

does that clear up anything for you though?
..can the lack of SOA suite have anything to do with the problem?

How to autopopulate fields in a portal form based on database procedure?

Dear gurus, I am a newbie to the portal world and i have a rather unique problem. I have searched online but still cant find a solution to my problem. I have a portal form (AS version 10.1.4) based on a db procedure that accepts only one parameter. The form has about 12 fields, two of which are combo boxes. Because of the relationship b/n combo box 1 and combo box 2 and the rest of the form fields, the user has to start out by selecting a value in combo box 1. This auto populates combo box 2 (based on the previous selection). However, when the user selects a value from the populated combo box 2, this is supposed to trigger an action to query the database and retrieve values for the remainder of the form fields and populate them accordingly.
I tried to use p_session.get and set values but discovered that one cannot do this with form fields that are based on a procedure. I could write javascript to call a database procedure but i am not sure how to pass the return values from the database back to the javascript routine and then populate the remaining fields accordingly.
HELP ME PLEASE!!!
Thanks

Hi Venkat, create a section (section control) for each set of columns you want to hide/reveal. Put your columns in that section. Then set a rule on the dropdown so that if dropdown = "this" then show "this" section.

How to display links in a text-field in Portal forms?

In a database the content in a varchar2 field could include a link:
'Shortname <a ref="#" title="Full or long item name">Long name</a>'
In a Portal report this field is displayed like:
Shortname {color:#0000ff}_Long name_
{color}
where the last part is a link. When pointing to this link with the mouse, the full item name is displayed. If this field is displayed in a Portal form, however, it is displayed exactly as written first:
Shortname <a ref="#" title="Full or long item name">Long name</a>
Could anybody tell how this field could be displayed as a link in Portal forms? The field itself does not need to be updated, it serves as an identifier for trailing fields in the details of a MD-form. If the long name should be displayed in the field, you would need to scroll horizontal to see the other details.

Yes your point is clearer now. You wish to see an abridged form of a field data with the facility to see the full data when you hover on that data. just like what we see sometimes in hyperlinks.
Both of the methods I told you work to display a modified data value* (without modifying them in the databse) and I floated them after testing. Have used slightly different functionalities in some applications a while back.
To get the 'mouse hover' display, you may want to use the java-script event-handlers of the form elements.
Both methods work with the premise that we do not want to change field data in DB; only displayed-data needs to be different.
1. The idea to edit info using sql-queries or functions from default value attribute work is the main thing. how and what should we edit the data to produce is a plsql-coding problem. So for instance, for a data example like yours, the following works!
assumption: the desired field is LINKS and is a column in PORTAL.TBL_TEST_FORMLINKS
SELECT DECODE(LINKS, NULL,NULL,SUBSTR(LINKS,INSTR(LINKS,'>','1')+1, LENGTH(LINKS)-INSTR(LINKS,'<','2'))) FROM PORTAL.TBL_TEST_FORMLINKS
If you need a different output or have a different requirement, then the example should be sufficient to guide you how to help yourself.
2. The other case of javascript embedded html in an additional plsql code also works. One such example is this:
<pre>
BEGIN
HTP.PRINT('<SCRIPT LANGUAGE="JavaScript1.1">
// find the element you want to edit first;
// hint: you may use this scheme and some basic jscript to extract the field LINKS : FORM_NAME.DEFAULT.LINKS.01
// now use javascript to get its value; treat it to fit your requirement; and equate it back to the LINKS element;
</SCRIPT>');
EXCEPTION
When Others THEN
null;
END;
</pre>
-- now follow my other instruction on FORM attributes in my second reply to see what you want to see.
these hints should be more than enough for anyone familiar with these technologies.
