Iterate over some output text in a panel Grid

Hello folks
Are any of you doing something like this in JSC
<code>
<%
for (int i = 0; i<4; i++)
%>
<h:panelGrid bgcolor="gray" binding="#{Page1.gridPanel1}" id="gridPanel1" style="height: 73px; left: 0px; top: 120px; position: absolute" width="216">
<h:outputText binding="#{Page1.outputText1}" id="outputText1" value="Author"/>
<h:outputText binding="#{Page1.outputText2}" id="outputText2" value="Summary"/>
<h:outputText binding="#{Page1.outputText3}" id="outputText3" value="Article link"/>
</h:panelGrid>
<%
%>
</code>
What I'm trying to do is something like data table, except that I want to have control over where the output text goes, and how it is presented.
In data table all I get is a predefined table (I�m unable to format it the way I would like) so lets do it the old way - link some output text to a database or maybe an array which holds the "data" then loop over it x number of times to display the content kind of like this
For (less than x times) do
Author name
Date article written
Summary article
Link to more of the article
This would be the way I used to this, now I�m curios how this is done using JSF
<% loop here %> does not mix well in Creator, error not well formed
I�m unable to format a data table in any respect except number of rows and stuff
So Any suggestion on how to really do this effectively in JSC/JSF
Thanks Bjorn

Hi,
Actually, you have quite a bit of flexibility with the Data Table component.
You can add more than one component to a column,
and you can use an outputText component to hold
HTML formatting tags, such as <br>.
Note: you must uncheck the escape attribute.
And since the data table component produces an HTML <table> tag,
you can also control style with additional style sheet classes (see Tor's blog).
For an example of using the Data Table component
to display the resuts of the Google search web services,
See Beyond the Book at this URL:
http://www.asgteach.com/download/beyond.pdf
The relevant description is section A.5 beginning on page 24.
Hope this helps.

What is the best way to store and iterate over lists of words?

Hi,
Im trying to create a naive bayesian classifier to attribute aurthorship to some texts. I have three text files in the form of a list of words (listA, listB and listC, where listA is a disputed text and listB, listC are those of known authors). I need to feed these into my program, than compare listA to listB (to check if listA has the same words as listB), perform the classification and do the same for listA and listC.
Im new to java and would like to know the best way of comparing the text files....could i store listA in an array....listB in a hashmap, iterate over the hashmap to check which words are also contained in listA and store the similar words in a seperate arraylist?
plz help.

If you just want to check if one set of words contains another set of words then something implementing java.util.Set might be sufficient. Read the API docs, you don't need to write much code yourself. Maps are for looking up values based on keys; your problem statement doesn't mention that so you don't need them. Lists are for when the order of entries matters. Read this for more information:

How can I iterate over the columns of a REF CURSOR?

I have the following situation:
DECLARE
   text   VARCHAR2 (100) := '';
   TYPE gen_cursor is ref cursor;
   c_gen gen_cursor;
   CURSOR c_tmp
   IS
        SELECT   *
          FROM   CROSS_TBL
      ORDER BY   sn;
BEGIN
   FOR tmp IN c_tmp
   LOOP
      text := 'select * from ' || tmp.table_name || ' where seqnum = ' || tmp.sn;
      OPEN c_gen FOR text;
      -- here I want to iterate over the columns of c_gen
      -- c_gen will have different number of columns every time,
      --        because we select from a different table
      -- I have more than 500 tables, so I cannot define strong REF CURSOR types!
      -- I need something like
      l := c_gen.columns.length;
      for c in c_gen.columns[1]..c_gen.columns[l]
      LOOP
          -- do something with the column value
      END LOOP;
   END LOOP;
END;As you can see from the comments in the code, I couln'd find any examples on the internet with weak REF CURSORS and selecting from many tables.
What I found was:
CREATE PACKAGE admin_data AS
   TYPE gencurtyp IS REF CURSOR;
   PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT);
END admin_data;
CREATE PACKAGE BODY admin_data AS
   PROCEDURE open_cv (generic_cv IN OUT gencurtyp, choice INT) IS
   BEGIN
      IF choice = 1 THEN
         OPEN generic_cv FOR SELECT * FROM employees;
      ELSIF choice = 2 THEN
         OPEN generic_cv FOR SELECT * FROM departments;
      ELSIF choice = 3 THEN
         OPEN generic_cv FOR SELECT * FROM jobs;
      END IF;
   END;
END admin_data;
/But they have only 3 tables here and I have like 500. What can I do here?
Thanks in advance for any help!

The issue here is that you don't know your columns at design time (which is generally considered bad design practice anyway).
In 10g or before, you would have to use the DBMS_SQL package to be able to iterate over each of the columns that are parsed from the query... e.g.
CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2) IS
v_v_val     VARCHAR2(4000);
v_n_val     NUMBER;
v_d_val     DATE;
v_ret       NUMBER;
c           NUMBER;
d           NUMBER;
col_cnt     INTEGER;
f           BOOLEAN;
rec_tab     DBMS_SQL.DESC_TAB;
col_num     NUMBER;
v_rowcount NUMBER := 0;
BEGIN
-- create a cursor
c := DBMS_SQL.OPEN_CURSOR;
-- parse the SQL statement into the cursor
DBMS_SQL.PARSE(c, p_sql, DBMS_SQL.NATIVE);
-- execute the cursor
d := DBMS_SQL.EXECUTE(c);
-- Describe the columns returned by the SQL statement
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
-- Bind local return variables to the various columns based on their types
FOR j in 1..col_cnt
LOOP
    CASE rec_tab(j).col_type
      WHEN 1 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_v_val,2000); -- Varchar2
      WHEN 2 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_n_val);      -- Number
      WHEN 12 THEN DBMS_SQL.DEFINE_COLUMN(c,j,v_d_val);     -- Date
    ELSE
      DBMS_SQL.DEFINE_COLUMN(c,j,v_v_val,2000); -- Any other type return as varchar2
    END CASE;
END LOOP;

    EXIT WHEN v_ret = 0;
    v_rowcount := v_rowcount + 1;
    DBMS_OUTPUT.PUT_LINE('Row: '||v_rowcount);

Welcome to the issues that are common when you start to attempt to create dynamic code. If your design isn't specific then your code can't be either and you end up creating more work in the coding whilst reducing the work in the design. ;)

Truncate output text in hierarchyViewer component

Hi,
I want to display the text with truncated to 30 characters only. I identified the outputText and added the truncateAt attribute and set it to 30. but it doesn't seem to work. Moreover the line - truncateAt="30" is underlined with orange squiggly lines indicating that there is some error and when I mouse over it , it says that this attribute is not supported when the component is inside of a hierarchyViewer component.
Any pointers how can I truncate the output text to 30 characters only?
Thanks,
Dhirendra

hi Vinod,
Thanks for the reply.
I have run it and it doesn't work. Use case is that we have a hierarchy viewer and I want to just truncate the long names of the Node Title.
Here is my local deploy link
http://rws65447fwks:7101/projectsManagement/faces/ResourceManagementDashboard
All I want to do is truncate the Node Title and limit it to lets say 30 characters. So "Resources with No Pool Membership" becomes "Resources with No Pool Mem..."
I tried to change in the jsff file and add the attribute called truncateAt and set it to 30, but as I said it says by underlying squiggly lines that the attribute is not supported.
Please let me know against what team should I file a bug? or it has to bean SR?
Thanks,
Dhirendra

How can a TableView iterate over Rows and get Cells?

I need to iterate over all the rows in a TableView without using Events. I would like to get the total number of rows, the TableRow, and a Cell from a specified TableColumn in the TableRow.
Something like this:
for(TableRow tableRow: tableView.getRows()){
    Cell cell = tableRow.getColumn(4).getCell();
    // do something to the cell
}Is this possible?
Edited by: Conzar on May 19, 2013 11:18 PM

However, the problem with the CheckBox has been resolved so I don't need to iterate over the rows any longer.Yep, not using lookups to handle this is a much better solution, I just provided my lookup based solution because you asked for an iterative solution.
The (lookup) code below doesn't produce any output.It works for me, I included an executable sample so you can try it out.
My guess is that you aren't taking into account the fact that the lookup is just a snapshot of the table's cells at a moment in time.
If you do a cell lookup before you show the table on a stage, it's not going to return anything because the cells are only generated on an as needed basis and there is no need to generate any cells before displaying the table on a stage.

I have a Text control string box with some initial text. I would like to highlight old text with click of mouse and type in new data from keyboard

I have a text control string box with some initial text (says: Please enter Name). I would like the operator to click on the text control box and have it automatically highlight so that when new data is typed in the old erases (all at once) and the new data is now in the text box.
I tried using the "Text.Selection" property node and when I run it and put the mouse inside the text box the initial text is highlighted and if I press "delete" on the keyboard or if I start to type in new data the initial data does delete but once I start to type new characters they erase each other. For example if I want to type in “Willi
am” I type the “W” and then the “I” but the “I” erases the “W” and now I am only left with an “I” in the text box and so on. I appreciate any help

It seems you are continuously setting the property node over and over again. This should only happen once if you mouse over it.
Create a property node for your text control with the following three items:
(1) KeyFocus (wire a "true" constant to it)
(2) Text.SelStart (Wire a "zero" constant to it)
(3) Text.SelEnd (Wire a constant containing the string length of the text).
Put this property node inside an event structure, triggered by "Mouse enter" on the string control.
(see if the attached example works for you)

JSF How to iterate over the list of a panelForm's child elements.

Hi all
My users have asked me to create a "clear all" button that initializes all input values of a search form's fields to null.
To do this I created a managed bean and added the following code
public String ClearFieldsBtn_action()
String[] fieldIDs = {
"Material",
"Description",
"Length",
"Width",
"Thickness",
for (int i = 0; i < fieldIDs.length; i++ )
try {
AttributeBinding attr = (AttributeBinding)getBindings().getControlBinding(fieldIDs);
attr.setInputValue( null);
} catch (Exception e) {
System.out.println(e.toString());
return null;
I wonder if there any other more elegant way to iterate over the fields contained inside the JSF panelForm that contains all these "Material", "Description", etc fields and thus be able to easily transport the same functionality in more that one page?
Thanks in advance
Thanassis

Thanassis,
I use some code like this (where "target" is a variable in the managed bean representing the parent component - the panelForm in your case):
    List children;
    int i, cnt;
    children = target.getChildren();
    cnt = target.getChildCount();
    for (i=0; i< cnt; i++)
      // do whatever you need here, such as clearing fields
    }This doesn't operate on the model, just on the UI components themselves. I do use something like this in a superclass backing bean for when I need to iterate over a bunch of UI components.

How do I place a transparent image over specific, centered text?

I'm helping someone with a site that flows sales copy down the center of the browser window. We want to take a transparent oval and place it over a price that will be in the copy. (It would look like someone took a marker and circled the price.)
I had learned that AP Div could solve this problem and, to an extent, it does. I can place the oval right over the price. But it only works when the copy is left justified, not centered. If the copy is centered, I can place the oval, but if the browser window is resized, the oval stays in place while the copy is reflowed to the new browser window size. Thus the oval is no longer over the correct text.
Then I learned that Layout Mode might solve this problem, however that has been removed from CS4.
So now my question is how do I to take a transparent .png file and place it over copy on this site so that if the browser window is resized, the .png file stays with the correct text as the text is "moved" to stay in the center of the brower window?
I want to avoid the workaround of simply creating a .png with the oval and the price and inserting that in the middle of the copy at the appropriate place. There must be a better way to handle this. Not being too familiar with Dreamweaver, maybe there's some sort of Anchor function similar to one in InDesign that solves this issue.
I've attached the simple oval .png file we're trying to use for this.
Thanks in advance for any help.

How about having the circle underneath the text? I know it's a compromise, but it will be much easier to do as you can assign a background image to the div or table cell which holds the text.
For example, make a blank graphic and create a class:
.price
background-image: url(nocircle.png);
then assign it to the text and give each text div a unique name
<div class="price" id="price1">10.99</div>
then you can turn the background image on and off using Dreamweaver's javascript controls, for example:
onclick="MM_changeProp('price1','','background-image','url(circle.png)','DIV');"
Hope that helps.

Mousing over some UI elements doesn't always display the correct pointer

When I mouse over some elements in a UI, sometimes the mouse cursor isn't correct. For example, when typing this message, if I open up 'Launchpad' by using the gesture, my mouse cursor stays as the text cursor, not the mouse pointer arrow, as I would expect.
This is only one example.. i've noticed it happens in many other instances.

My problem seems to be solved. My Norton Internet Protection software notified me that the Photoshop Auto Analyzer was using a lot of CPU and memory. I shut off all Media Analysis in PSE-11, and I have not had any of the problems I mentioned in my posted question.
I am surprised that my PC chokes up and causes errors when Media Analysis is on. Has anyone seen this before?

Problem of diappeared output text as soon as page refreshes

Hi all,
I have jspx page with following code
<?xml version='1.0' encoding='windows-1252'?>

</af:commandButton>
<af:outputText id="greeting" value="" clientComponent="true"/>
<trh:script>
function sayHello(actionEvent)
var component=actionEvent.getSource();
//Find the client component for the "greeting" af:outputText
var greetingComponent=component.findComponent("greeting");
//Set the value for the outputText component
greetingComponent.setValue("Hello World !");
</trh:script>
</af:form>
    </af:document>
</f:view>

</jsp:root>When I run this page in output I get an InputText box and a command button "Say Hello" . When I click on the button it shows message "Hello World" for a while and then page gets refreshes and "Hello World" message disappears.
Is it possible to retain that message? Is it possible to display that message without clicking command button ? How it can be done - Please tell ?
Thanks !

Hey branislav,
Thanks a lot. I figured out problem in my code after looking at your code.
Now my following modified code is working fine. Problem was I need not to include input text and command button components in <af:form> tag. Only output text need to included in <af:form> tag.
<?xml version='1.0' encoding='windows-1252'?>

      <af:form>
        <af:outputText id="greeting" value="" clientComponent="true"/>
      </af:form>
<trh:script>
function sayHello(actionEvent) {
     var component=actionEvent.getSource(); //Find the client component for the "greeting" af:outputText var
      greetingComponent=component.findComponent("greeting"); //Set the value for the outputText component
      greetingComponent.setValue("Hello World !");

Issue using JS to change the value of an output text component dynamically

I am developing an application and I need to change the output text component value at run time when the mouse moves over a field. I am using javascript and then using UIComponent.setproperty to change the value.
I am not able to do this and am getting nothing.
Kindly let me know what am I doing wrong
I am using ADF 11g (10th November release).
Regards,
Deepak

Hi i'm doing the same thing with an input text
here is my code
jspx:
<af:inputText value="#{bindings.MiddleName.inputValue}"
label="#{bindings.MiddleName.hints.label}"
required="#{bindings.MiddleName.hints.mandatory}"
columns="#{bindings.MiddleName.hints.displayWidth}"
maximumLength="#{bindings.MiddleName.hints.precision}"
shortDesc="#{bindings.MiddleName.hints.tooltip}"
id="it4" autoSubmit="true">
<f:validator binding="#{bindings.MiddleName.validator}"/>
<af:clientListener type="valueChange" method="mo_UpperCase"/>
</af:inputText>
js:
function mo_UpperCase(event){
var inputField = event.getSource();
if (event.getNewValue().toUpperCase()!=event.getNewValue())
inputField.setValue(event.getNewValue().toUpperCase());
In my case i change the input text to upercase when the value is changing
I hope it works with output text also,
change my examples clientlistener type from valueChange to mouseOver

How to add output text programmatically??

Hi Team,
Jdev Version - 11.1.1.6.0
I have a requirement like-
I want to add output text on click of button mean programmatically. Everytime i click on button output text get add above previous output Text.
Just like in blogs user share their comments and once click on share it gets add in list above previous comment.
I have pop up and once i fill fields in popup and click on OK button of pop up, comment will add in list.
Could you please help me how i can add output text on click of button one above one.
Thanks in Advance.
Thanks & Regards,
Ramit Mathur

1) Use a Collection to hold the comments. It could be in-memory (List<String>) or backed by DB (using a ViewObject) depending on your use-case. On every comment submission add the comment to the collection object.
2) In the page, iterate through the collection using af:iterator and include the output text within the iterator.

Debugger output text is centered

In Coldfusion 9, when I enable "Enable Request Debugging Output" in the administrator settings, the debugging text on my site pages is centered from "Scope Variables" to the end of the output. One of the fields is so wide that I have to scroll right just to see the centered text.
I can't find a setting to control the output text to make it a more readable left-aligned. I've been working on a CSS hack to control the styles. But I've only figured out how to do it within the code of each cf template. Has anyone figured how to fix this poorly designed text?
Thanks!

Usually this is more a reflection of a problem in the HTML that your own code is generating. Consider that the debugging output is merely HTML at the bottom of the HTML your own page generated. CF sticks a bunch of closing tags into the stream between the two, hoping to “close” any tags you may have left open, but it’s just guessing. You may (indeed, it seems you must) have one open (either a
tag, or one that sets centering, like
, or perhaps it’s even some CSS controlling things.
But to answer your question, no, there is no feature to control this.
I would recommend you run your code against an html validator, like http://validator.w3.org/, to find out what is perhaps “broken” about your HTML.
Hope that helps.

Flahing output text

Hi All,
i have an adf page that i am displaying status's on they are retrived from a database table...
i just wanted to know if it was possible to have these status's displayed (currently as output text) with some sort of flashing java script around them...
is the best way to create some gif files and have them displayed instead of the output text...
i am using jdeveloper 10.1.3 and oracle 10g...
any help would be really be appriciated...
thanks

Hi,
you can always add JavaScript on the page, set clientComponent="true" on the output text, find a component handle on the page and do the flashing thing. However, I think that using animated gif is more robust, less error prone and easier to implement

Table Output text tool tip does not update on PPR

We have a adf table with a Lov and a out put text .
On changing the LOV, the out put text also change . but, on we mouse over on the tool tip does not changed . any suggestions ?
below code :
<af:outputText value="#{row.PlanTitle}" id="ot4" partialTriggers="soc3 si2"/>
However , if we refresh the table or reload after save , the toop tip also get change . but we need to update the tool tip on change the lov . any suggestion ?
Jdev : 11.1.1.3.0
browser : all ,

Hi,
taking it from:
+"However , if we refresh the table or reload after save , the toop tip also get change . but we need to update the tool tip on change the lov . any suggestion ? "+
The autput text component is part of a table ? If so then the table needs to be refreshed as the values in there are stamped. If I am wrong with my table assumption and the output text is part of a form, try setting clientComponent="true" for the output text field
