Passing a parameter to a Item Renderer

I have a dataGrid with about 12 columns. I want to render an
image in each cell based on the value of that node. Problem is: I
need the renderer to know what node to evaluate.
<mx:DataGridColumn width="20"
itemRenderer="com.apts247.www.renderers.Test" paddingLeft="0"
color="#990000"/>
<mx:DataGridColumn width="20"
itemRenderer="com.apts247.www.renderers.Test" paddingLeft="0"
color="#990000"/>
When these hit the item renderer, how can i make it know what
data to evaluate. I want to pass it, for example, "task_0", or
"task_1"

If the Itemrenderer implements the IDropInListItemRenderer
interface, you have access to the listData property which contains
information like column index and dataField.

Pass a value to an item renderer button

I have a datagrid. One of the columns has a value of "@recipe", with is a string that's a URL.
I need to replace this with a link button that goes to this url.
So I created an Item Renderer:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private var linkToGoTo:String = XML(data).@recipe
          private function goRecipe(event:MouseEvent):void {
          trace("Link="+linkToGoTo);
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="Related Recipe" click="goRecipe(event)" />
</mx:Canvas>
Problem is that I am not getting my XML value.   If I did this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private function goRecipe(event:MouseEvent):void {
          trace(event.currentTarget.label);
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="{XML(data).@recipe}" click="goRecipe(event)" />
</mx:Canvas>
This works, but of course I do not want the label to be this long URL. How would I do this?

OK, I got it to work like this, not sure if it's the best way:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
     <![CDATA[
          private var relatedRecipe:String
          override public function set data(value:Object):void
        if(value != null)
           super.data = value;
           relatedRecipe = value.@recipe
           if (relatedRecipe.length>1) {
                trace("recipe="+relatedRecipe);
                related.visible = true;
           } else {
                related.visible = false;
        private function goRecipe(event:MouseEvent):void {
             var linkToGoTo:URLRequest = new URLRequest(relatedRecipe);
             navigateToURL(linkToGoTo, "_blank");
     ]]>
</mx:Script>
<mx:LinkButton id="related" label="Related Recipe" click="goRecipe(event)" textDecoration="underline" fontSize="10" styleName="recipeLinkButton" />
</mx:Canvas>

Item Renderer passed to legend

Hi,
I have written an item renderer in Action script to change
the shape of the columns on a column chart. How can I pass this
through to the Legend?
I tried adding:
legendMarkerRenderer=
"myRenderer"
itemRenderer="myRenderer"
inside the column series tags of my mxml but this didn't work
- I just got a blank screen when I tried to run the application.
If I put
legendMarkerRenderer=
"mx.charts.renderers.DiamondItemRenderer" this works OK -
but of course, it isn't what I want.
Do I need to put something inside my action script to tell it
to pass the info to the legend?
Thanks in advance for any help.
M

Be sure to include the full classpath to your renderer in the
reference within your MXML. For example, if the package that your
renderer is in is com.example and the name of your renderer's class
is MyRenderer, you would write the following:
legendMarkerRenderer="com.example.MyRenderer". Keep in mind that
case matters.
If this doesn't work, there is probably something wrong with
your ItemRenderer, so you should post that code and we can help you
out.

Click event on a item renderer stops data being passed

Hi
I'm trying to create a item renderer based on a Canvas, this renderer is then used in a List component. I'm trying to get a click event fired when the user clicks on one of the items in the List. I'm also formatting the data being passed into the item renderer to do this I'm overriding the set data property like this:
override public function set data(value:Object):void
title.text = value.marketName;
sellPrice.text = value.sellPrice;
buyPrice.text = value.buyPrice;
change.text = value.percentageChangeOnDay;
var i:String = "-";
if(String(value.percentageChangeOnDay).indexOf(i))
change.styleName = "PositiveChange";
else
change.styleName = "NegativeChange";
When I add a click event to my item renderer like this,
<view:DisplayItem click="itemClickedEvent( event )" />
I get a null reference error in my set data function. If I remove the click event the data is passed correctly, I've also found that if I use a rollOut event like this,
<view:DisplayItem rollOut="rolledOverEvent( event )"/>
the data is passed fine and the event works too, it seems that click events cause the data not to be passed.
Why does having a click event cause this problem? How can I have a click event on the item renderer and still format my data?
Cheers
Stephen

Found out that I can use the itemClick event of the List component I'm using my item renderer in, so really my item renderer does not need a click event.

Getting the value of a checkbox in an item renderer?

I have a list that uses an item renderer with buttons and data. I need to add a checkbox and get the value of this checkbox passed along with the event of the pushbutton.
When the user clicks "add to menu: there is a click handler:
protected function addButton_clickHandler(event:MouseEvent):void
                    doubleIt = double.selected;
                    owner.dispatchEvent(new Event("ADD_TO_MENU", true));
Back in the main application, there is a listener for this event. I want that handler to be able to "know" the status of that checkbox (i.e. the value of "doubleIt", defined as a public boolean).
private function addToMenuHandler(event:Event):void {
           var i:int = event.target.selectedIndex;
           var obj:Object = new Object();
           obj = recipeListCollection.getItemAt(i);
           menuList += obj;
I have tried various permutations of the event.target, but can't figure out how to access that variable.

Create a custom event and stuff anything you want in there.

How to pass dynamic parameter to a database function in OBIEE

Hi,
I have a requirement like this. I have to create one report in OBIEE which was in Discoverer. Now in discoverer report there are some calculated item in the worksheet based on database pkg.functions. The parameter which user gives at run time that parameters are then passed to the discoverer calculated items dynamically. But I am not able to do this in OBIEE answers.
Can anyone tell me step by step how I can able to pass the user selected parameter values in OBIEE answer level.
The example:
GET_COMM_VALUE_PTD("AFE Cost & Commitment".Afe Id,:"Period Name(AFE)","AFE Cost & Commitment".Data Sel,"AFE Cost & Commitment".Org Id)
GET_COMM_VALUE_PTD --- Function database
("AFE Cost & Commitment".Afe Id,:"Period Name(AFE)","AFE Cost & Commitment".Data Sel,"AFE Cost & Commitment".Org Id --- Parameters... :"Period Name(AFE)" is the dynamic parameter selected run time by user.
Please help.
Thanks
Titas

Hi,
I already did that. But the existing discoverer re value report is showing correct value but the OBIEE report with EVALUATE function shows incorrect value.
The requirement is to create a OBIEE Dashboard from a Discoverer existing report. Now in discoverer report theere are several calculated items in worksheet level where database custom function is used and user selected parameter value is passed run time in that function. But when that is created in OBIEE with EVALUATE function in RPD, the report shows incorrect data. Could not understand how to pass the parameter value runtime.
Below is the discoverer 'Show SQL' query and EVALUATE function syntax which has been used.
SELECT APPS.XXBG_PL_PROJ_ANALYSIS_AFE_PKG.GET_COMM_VALUE_PTD(XXBG_PL_PROJ_AFE_V.AFE_ID,
:"Period Name(AFE)",
XXBG_PL_PROJ_AFE_V.DATA_SEL,
XXBG_PL_PROJ_AFE_V.ORG_ID),
XXBG_PL_PROJ_AFE_V.AFE_DESC,
XXBG_PL_PROJ_AFE_V.AFE_NUMBER,
XXBG_PL_PROJ_AFE_V.APPROVED_AFE_AMOUNT
FROM APPS.PA_PERIODS_ALL PA_PERIODS_ALL,
APPS.XXBG_PL_PROJ_AFE_V XXBG_PL_PROJ_AFE_V
WHERE ((XXBG_PL_PROJ_AFE_V.ORG_ID = PA_PERIODS_ALL.ORG_ID))
AND (XXBG_PL_PROJ_AFE_V.DATA_SEL = :"Data Selection(AFE)")
AND (PA_PERIODS_ALL.PERIOD_NAME = :"Period Name(AFE)")
AND (XXBG_PL_PROJ_AFE_V.AFE_NUMBER = :"AFE Number(AFE)")
AND (XXBG_PL_PROJ_AFE_V.OPERATING_UNIT = :"Operating Unit(AFE)")
The EVALUATE function syntax is as below:
EVALUATE('XXBG_PL_PROJ_ANALYSIS_AFE_PKG.GET_COMM_VALUE_PTD(%1,%2,%3,%4)' AS FLOAT , "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Afe Id", "BG PL Project Analysis Report_1"."Periods 1"."Periods 1.Period Name", "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Data Sel", "BG PL Project Analysis Report_1"."AFE Cost & Commitment"."AFE Cost & Commitment.Org Id")
The PERIOD needs to be passed at run time which user will select.
Please help to solve the issue.

Pass a parameter to Surikogiflex client

Hello all,
I'd like to know if it is possible to pass a parameter to Surikogiflex client, to be able to tell it to open a certain story.
For example, I wonder if it is possible to have in an html page a link like
<a href="localhost:8400/suribachi/clients/surikogiflex/?icml=/documents/doc1/story1.icml">Ed it story in Surikogi</a>
and when the user clicks it have Surikogiflex client open loading the selected story, without passing from the Document browser window.
Is something like this possible?
Please assume that the correct <story> tags are present on the storylist.xml file in the /suribachiassets directory.
Thanks.

i am trying to pass the parent_id as a parameter to a portal page but am not able to... i can add it to the list of in parameters to the PL/SQL based parent id but when i add the parent id to the url then i get no result... i created a custom attribute for the parent id since there is no attribute build other then page group and page id... when I set the Parent ID attributes default value in the attribute properties of the item type based on PL/SQL it just brings back results for the default value and if i pass a different value for ithe parent id i dont get the correct result I get the result for the default parent id.

How to auto login and pass data (parameter) to ApEx at the same time

Does anybody know how to automatically login to apex (e.g. from JSP page) and pass a parameter value at the same time? I can use wwv_flow_custom_auth_std to login, I can even choose a page but I cannot pass any data (at least I do not know how). If I use f?p URL syntax I can pass data but there is no way to pass login/password information.
Any idea? Thanks Jaros

Jaros -
You could copy your login page and make the new page "public". On the new page, add a process before the login process that sets the value of application item FSP_AFTER_LOGIN_URL to the report page URL (with the arguments), e.g., :FSP_AFTER_LOGIN_URL := 'f?p=&APP_ID.:100:&SESSION.::NO::P100_X,P100_Y:&RPT_VALUE1.,&RPT_VALUE2.';Create application-level items RPT_VALUE1 and RPT_VALUE2 in the application.
From your external page, POST to this new "login" page, passing values for the username, password, rpt_value1, and rpt_value2 items.
Let us know if it works.

Item Renderer in a Datagrid

I'm struggling with how to make a check mark ( image ) show
up or not based on the value of some data in each datagrid line
item. I'm using an item renderer but I'm missing something. Any
help would be greatly appreciated.
thanks,
STeveR

The following is my entire itemrenderer...please excuse any
bad style as this is a WIProgress..
Its probably easier to quote the adobe docs on listdata...If
a component implements the IDropInListItemRenderer interface, you
can use its listData property to obtain information about the data
passed to the component when you use the component in an item
renderer or item editor..I made sure the component implements the
interface as you can see in the code at the top of component. Then
add the couple of required functions regarding listdata, then you
can access the listdata in your own functions in the renderer, like
i do in set data function.
this.BTN_***_mark.label =
value[DataGridListData(listData).dataField];
this line assigns the value from my datagrid to the renderers
button label. (this renderer is a button that the user can press)
so i want the buttons label to show the value coming in from the
datagrid. So listdata is just a way to
explicitly get the column name where the current data is
being sourced from in your datagrid.As the grid is being rendered,
it renders row by row. In each row it goes thru your columns . SO
initially it for row 1 it would begin rendering firstname, surname,
mark, average...etc etc. If i put an alert in on
value[DataGridListData(listData).dataField
I would see these column names popping up as they are getting
rendered in the DGrid.
Hope this helps...

Is it possible to pass a parameter to ON_DEMAND process?

Hi guys.
In AJAX, is it possible to pass a parameter to ON_DEMAND process?
(I get value in javascript and want to pass it to on_demand process...)
Thanks.
Mike

Hi Mike,
Yes, provided you have set up an Application Item to receive the value you can use this within your PL/SQL code.
I've detailed what needs doing here:

Pass a parameter from a report to a customization form of another report

Hello,
I want to pass a parameter value from a report to the customization form of another report and display it in the text field in the customization form as a default value. I have 2 variables in the customization form and in one of them, I would like to display the default value from a previous report.
Thank you
Jayasree

1. go to the manage component screen of the report
2. open the package body (pl/sql source)
3. search for 'procedure show_parms'
4. scroll down till you find
-- call to parameter form rendering engine
5. copy the procedure call below it
a) you will have to pass <PORTAL_SCHEMA>.wwv_utlglobl.RUN_AS_NORMAL to p_mode
b) remove the parameters p_reference_path, p_redirect_url, p_exec_mode, p_page_url ( or you can pass null to them)
c) 'p_parm_names' will contain your 2 parameters
d) you can pass values to 'p_parm_values' which you want to be displayed in the parameter forms.
6. you can call this procedure from a dynamic page and link the dynamic page to your first report

Generic item renderer for Adv DG Columns?

Hello,
I'm trying to create a generic ItemRenderer for my Adv DG so that so that I can put a toolTip on the cells.
The Adv DG Column object doesn't have a toolTip property so I'm creating my own renderer...
As far as I'm aware I have to create an ItemRenderer that knows the fieldName that it is rendering so I can use {data.myFieldName}. I was hoping there was a property so that I can reference the value generically such as {data.text} but this obvisouly doesn't work...
Is there anyway around this? Can I pass a paramater to the itemRenderer? I'm doing it like this...
advancedDataGridColumn.itemRenderer = new ClassFactory(renderers.ToolTipFieldRenderer);
Alsok, there is a toolTip property of the AdvDG but the columns, what is the AdvDG.toolTip used for? Just a general toolTip? The reason why I need a toolTip is our client has asked to be able to mouse-over the cell to see the full value where the field value is chopped because it's too long for the column...
Hope that makes sense and hope you can help...
Cheers,
Nick

The AdvancedDataGridColumn class has dataTipField and dataTipFunction
properties and these are supported by the default item renderer
(AdvancedDataGridItemRenderer), which is also generic. Here's an example:
<?xml version="1.0" encoding="utf-8"?>

    </mx:Script>
    <mx:AdvancedDataGrid
        height="400"
        width="300"
        sortExpertMode="true"
        dataProvider="">
        <mx:columns>
            <mx:AdvancedDataGridColumn
                dataField="Artist"
                dataTipField="Artist"

            <mx:AdvancedDataGridColumn
                dataField="Album"
                dataTipField="Album"
                showDataTips="true" />
            <mx:AdvancedDataGridColumn
                dataField="Price"
                dataTipField="Price"

Two item renderer for one datagrid column?

hi
i have one doubt
can we use two item renderer for one datagrid column
any possibilities
why i am asking this because
during drag and drop i need one itemrenderer and during application initialization i need another itemrenderer
any possibilities
karthik.k

Hi,
I think your requirement can be completed by using ViewStack you can pass selected index to it according to requirement.
See:
<itemRenederer ...
     <viewstack selectedIndex = 0 ...>
          <vBox id="vBox1" >
                    Your 1st itemrenderer will come here....
          </vBox>
          <vBox id="vBox2" >
                    Your 2nd itemrenderer will come here....
          </vBox>
     </viewStack>
</itemRenederer>
You have to just toggle selectedIndex.
Thanks
