How to set the text for commandNavigationItem in nodeStamp facet of train?

When I use the af:train w/o ndeStamp facet, the train displays proeprly with text next to each nod, e.g.,
<af:train id="train" var="node" value="#{controllerContext.currentViewPort.taskFlowContext.trainModel}" layout="vertical"/>
but when I use a nodeStamp, then my text dissappears. e.g.,
<af:train id="train" var="node"
value="#{controllerContext.currentViewPort.taskFlowContext.trainModel}"
layout="vertical">
<f:facet name="nodeStamp">
<af:commandNavigationItem text="#{node.text}" actionListener="#{pageFlowScope.createModelFromTables.onSelectTrainStop}"/>
</f:facet>
</af:train>
Also, jDeveloper complains that it Reference "#{node.text}" not found. Likewise for #{node.readOnly}, etc. Note I also tried #{node.label} as described in the code example [adf:train|http://jdevadf.oracle.com/adf-richclient-demo/docs/tagdoc/af_train.html]
I am using jDeveloper 11.1.1.5.0 Build JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013

         set TYPE wdy_key_value_table,

         v1 type string value 'MAGO',
         k2 type string value 'S',
         v2 type string value 'Saurav'.
value1-key = k1.
value1-value = v1.
APPEND value1 to set.
value1-key = k2.
value1-value = v2.
   APPEND value1 to set.
node_info = wd_context->get_node_info( ).
node_info = node_info->get_child_node('FOR_DROP').
node_info->set_attribute_value_set( name = 'DROP_KEY'   value_set = set ).

How to set the background for all components?

hi
Does anybody know how to set the DEFAULT background color in an application.. I need it because in jdk 1.3 the default bgcolor is grey and in 1.5 it is white.. and I wish white as well.. so to make it also white in jdk 1.3 I need to use the (a bit annoying) anyContainer.setBackground( Color.white ); and these are lots in my app.. So my question is: is there such an overall class with a function (say UIManager.setComponentsBackground( Color color ) ) for such a purpose?
any tip or link would be greatly appreciated

Does anybody know how to set the DEFAULT background color in an applicationthis might get you close
import java.awt.*;
import javax.swing.*;

How to set the conditions for item deletion approval workflow?

Hi,
I have created approval workflow for item modifications ie, when user try to modify an item, it will send a mail to Project Manager. For that I set the conditions in Change the behavior of the overall task: 1. When the task process starts 2 . When the task
process completes .
Change the behavior of the single task: 1.when a task is Pending.
[I followed this https://www.nothingbutsharepoint.com/sites/eusp/Pages/5-Steps-to-Enhance-SharePoint-2010-Approval-Workflow.aspx ]
My Requirement is that I want to set this same workflow for the scenario: when the user deletes an item it will send a mail (intimation mail for item deletion) to Project Manager. here i dont want to send modification mails when user deletes an item.
When user modifies an item: 1. intimation mail, 2. Approve/Reject mail 3. intimation for approval / rejection mail.
When user deletes an item: 1. intimation mail.
How can we set it in one approval workflow?? where i have to set the condition for sending either item modification mails or deletion mail.
Thanks,
Praveen ji

Hi,
According to your post, my understanding is that you wanted to start approval workflow when item deleted.
You should first make some changes to trigger the workflow when you delete the item.
You can use the Event Receiver to achieve it.
In order to trigger workflow on item delete you need to create event receivers and from event receiver call the workflow already attached with list.
http://ravendra.wordpress.com/sharepoint-workflow-on-list-item-delete/
You can also create custom action to start the workflow, you can refer to the following article, then modify the workflow as your need.

How to set the icon for the entire application with JFrame.setIconImage

I set the icon on the main frame using JFrame.setIconImage(). The icon is shown properly in the main frame.
If more JFrames are opened from the main frame, the newly opened JFrames also show the icon.
However if JDialogs are opended, in some cases the icon set on the main frame is shown and in other cases the coffee cup.
What is JFrame.setIconImage() expected to do? Setting the icon for a single JFrame or the entire application?
How can I set the icon for the entire application?
How can I set the icon for JDialogs?
Thank you

In order for your dialogs to use the same icon as the frame, you must parent the dialogs to the frame which has the custom icon.

How to pull the text for InfoObject in APD

Hi All,
I have a requirement where in I have to combine the data from 2 InfoObjects using an APD based on some conditions.
I need to bring in the text for these infoObjects and there attributes too.
The proposed solution from my side for pulling the text is
u2022 Getting the text from the text table u2013 this is working fine but the performance is not good.
u2022 Making a query above the object and taking the output as the APD input. Now, in the query , I have selected the display option u2018key and textu2019 but when I am using this query as input for the APD, I am not getting the text.
Please let me know how to get the text using the query output and/ or are there any other approach to get the text of an infoObject.
Thanks & Regards
Abhi

Hi,
It is possible to read the text tables of the infobject, for eg In material you can use table /BI0/TMATERIAL
You have to select a Datasource as the 'Database table and use /BI0/TMATERIAL as one of the underlying tables and then choose another datasource with /BI0/MMATERIAL as the underlying table.
Now that you have all the data that is needed you can use the join to connect the above two datasources .Select the join condition (material in this case) and the fields that you would like to be have to the next level from the individual tables that you have selected earlier.
I guess if you work in this way you might get the results that you are looking forward quite easily without writting code.
Let me know if it helps.

How to set the size for height of iView tray?

Hi,
I have created a ABAP webdynpro component and integrated this comp with iView. Then i integrated iView into Page in portal. That is working fine.
But the size of tray/window which is displayed in the page is very small.
How to increase the height of that Tray/window/iView containing my component?

Hi,
By changing the maximum automatic height and Minimum automatic height property of the iview you can set the size for height of your iview.
to do this follow the setps:
goto content administrator -> portal content -> your folder where you created your iview or directly to your iview -> right click -> open -> object,
and now in property category choose appearance-Size from the drop down menu and set the above properties to your required height.
if you want the end user to modify this property set the property to read/write .

How to set title/text for ALV table column header in WD ABAP

Hello,
I am working in WDA using SALV_WD_Table to display data in table. I need to change the column header text, the obvious way is to get the column header and call the method SET_TEXT to set new text / title. However, this method does NOT work, it does not change the column header text. I also tried the SET_TOOLTIP, this one works, but SET_TEXT does not work. Anyone has idea why this not working and do you find any go-around solution?
My version is NW 7.0

How to set the text of a cell in Numbers to vertical direction? Tks.

Hi
In Numbers, please tell me how to switch the text of a cell to vertical direction?
Tks.

Hi Kyle,
In Numbers, nothing having to do with a table can be rotated. (In Pages an entire Table can be rotated, but not text within a Table.)
There have been many suggestions posted here over the life of iWork for vertical labels. Most fall into three categories:
1. Type one letter, Option-Return, type another letter, Option-Return, and so forth.
2. Type label in a Text Box, rotate the box, position the box over the table, covering the cell where you need a label.
3. Create a PDF graphic with rotated text and insert it into table cell as Background Fill.
The third option is clearly the best. The steps for option three are:
Insert Text Box
Type label into the box
Rotate the text box
Select the text box (not the text inside the box)
Command-C
Switch to Preview.app
Command-N
Command-C
Switch to Numbers
Click on Cell where the label goes
Command-V
It sounds worse than it is. You can reuse the Text Box so you don't end up with a sheet full of them.
Regards,
Jerry

How to set the text color in a Canvas?

When I use (Graphics) g.setColor(255,255,255), then g.drawString("xxx", 0, 0, ....);
the simulator works well but it can't work in my mobile phone (Nokia 7650).
What's wrong?
Thanks.

do it like this
g.setColor(255,255,255);//this will set the color for the canvas
g.fillRect(0,0,ht,wd);//this will fill the rect(screen) with the above color,actually this will be BG color for ur app..ht,wd are the height and width of ur canvas...
now specify color for the text
g.setColor(r,g,b);//this color shud ofcourse be diff frm the color set for BG
now draw the string
g.drawString("xxx", 0, 0, ....);
