Custom Button Rendering/Disabling with Velocity Templates [SOLVED]

I have a custom button in my application that I only want to show up on specific pages and I can't seem to figure out a EL expression that will let me disable or not render the button on the following criteria,
- The velocity template will be installed on tableForm configured groups.
- I only want the button to be activated/visable when in the 'Details' view for a specific row
- When the group has insertions permitted.
I have tried to steal some code from the *.vm files for other buttons and items used by JHeadstart, but none of the expressions seem to be solving my problem. I have always found the Data Binding through EL Expressions with the ADF very confusing to work with so any guidance would be greatly appreciated. (Is there a way to 'debug' EL expressions to see the actual data that is available to me at any given time?)
Thanks.

My Case is :
The code of my button in Custom Template :
<af:commandButton text="Zone Charge Group Details"
rendered="true" disabled="false" immediate="true" >
<f:actionListener type="oracle.jheadstart.controller.jsf.listener.DoRollbackActionListener"/>
<af:resetActionListener/>
</af:commandButton>
my Custom Template is running successfully and button appear in runtime
But I want re-write this code so that this button is binded with a method in Managed Bean
Scenario is :
when click the button in a page, it calls a method in that Bean and pass a parameter to it.
And the ouptut of this method is displayed in another page.
There is no Error message....
Please, If you don't understand anything, Ask me .
My Question is :
How to bind Button to a Method in a custom Template?
Please,Reply me ASAP.
Thank you very much.

Rendering error with wrong template path

Hi there,

Any ideas

Hello,
I think at the moment you are passing the xdp template source as url using the WDURLGenerator.
Instead you should send it as a stream using the appropriate pdfdocument api like this:
String templateUrl = null;
ByteArrayOutputStream templateStream = null;
templateUrl = WDURLGenerator.getPublicResourcePath(otherPart, "My_InteractiveForm.xdp");
InputStream template = new FileInputStream(templateUrl);
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
              int nRead;
              byte[] data = new byte[16384];
              while ((nRead = template.read(data, 0, data.length)) != -1) {
                        buffer.write(data, 0, nRead);
              buffer.flush();
              templateStream = buffer;
IWDPDFDocumentHandler pdfDocumentHandler = WDPDFDocumentFactory.getDocumentHandler();
IWDPDFDocumentCreationContext pdfDocumentCreationContext = pdfDocumentHandler.getDocumentCreationContext();
pdfDocumentCreationContext.setTemplate(templateStream);
Hope this helps...

Using a Velocity Template in Java User Exit Custom Handler

I would have thought it would be possible to use a Velocity template in combination with a custom handler in a Java user exit, but I can't seem to figure out how to do it, and I'm not finding an example of doing this anywhere in the GoldenGate docs.
For example, I can create a Velocity template and use it to output transactions in the desired format to a file by using a propeties file that looks something like this:
gg.handlerlist=myhandler
gg.handler.myhandler.mode=tx
gg.handler.myhandler.format=./dirprm/my_template.vm
gg.handler.myhandler.type=file
gg.handler.myhandler.file=my_output.txt
What I'm hoping to do is to have a custom handler, and some how be able to get to the Velocity formatted transaction data in the "transactionCommit(DsEvent, DsTransaction)" method of my custom extension of AbstractHandler by having a properties file that looks like this (same as the above, except for the type, and no file property ... eg:
gg.handlerlist=myhandler
gg.handler.myhandler.mode=tx
gg.handler.myhandler.format=./dirprm/my_template.vm
gg.handler.myhandler.type=my.custom.GGHandler
I've verified that I have a valid DsEvent and a DsTransaction with the desired information in by custom handler's transactionCommit method ... and I can even pull out the required data and re-format it there to the desired format so that it looks just like the format that my Velocity template outputs when I'm outputting to a file (as shown in the first properties file). But shouldn't I somehow be able to access the Velocity transformation for my DsTransaction in my custom handler?
Thanks for any assistance / info provided.

Custom Buttons In Template Issue - Arrgh!

Hi,
I created a custom button in Photoshop, using the layer method specified in grayscale. I then created a custom template with six of these buttons. Then I imported a movie with embedded chapter indexes. When I drag this movie to an empty menu window and select my custom template for chapter index creation, the individual chapter video frames do not appear in the buttons, even though the text of these chapters do. The mask for the asset is set to white. If I drag an asset to the buttons, everything looks ok. What gives?.

I found a solution. I picked an Apple (heh) motion button and created a menu template with that button. Then I dragged my custom shape over each motion button and selected Set Shape. That created the motion buttons with my desired shape. I had to adjust the size and position of the new buttons, but at least it worked. I might also have changed the buttons to drop zones without all this work, but that's for another time.

Custom parameters in URL with BexWeb (WAD/Web template)

Hello all,
I've been reading a lot in this forum, but I haven't been able to do what I want to do.
I want to insert a custom parameter in the URL as we made with BW 3.5, and then read it.
I finally think it's something about the command SET_VARIABLES_STATE, but I cannon get it work.
In the template I have only been able to insert commands under the Web Template element (either before first display and before first rendereing, both with the same results). I've also tried several types of commands.
The XHTML generated is as follows:
                <bi:WEB_TEMPLATE_ACTIONS type="COMPOSITE" >
                    <bi:ACTION_BEFORE_FIRST_RENDERING type="COMPOSITE" >

                                    </bi:VARIABLE_VALUE>
                                    <bi:VARIABLE_VALUE type="COMPOSITE" index="3" >
                                        <bi:VARIABLE value="ZSESION3" text="ZSESION3"></bi:VARIABLE>
                                        <bi:VARIABLE_TYPE type="CHOICE" value="TEXT_VARIABLE" >

                                        </bi:VARIABLE_TYPE>

                                </bi:VARIABLE_VALUES>

                        </bi:INSTRUCTION>
                    </bi:ACTION_BEFORE_FIRST_RENDERING>
                </bi:WEB_TEMPLATE_ACTIONS>
I pass it in the URL this way:
&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE=VARIABLE_INPUT_STRING&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE-VARIABLE_INPUT_STRING=010/2010&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE=ZSESION
Also, I want to read it using the ABAP interface IF_BICS_CONS_WEBITEM_CUST_EXIT, method EXECUTE.
I wonder if it's possible that, once the command parameter works, that the value of my parameters arrives here in the I_XML in parameter.
I've also read about standard class CL_RSWR_SERVICES, but I don't really want to debug a std class and even less to enhace it ...
PD: This variable ZSESION does not exist in any query, and we don't want it to exist, as it's only necessary for integration in the intranet.
Thanks to all,
Rafa

Hi,
It is possible in 7.0, but unfortunately it is a lot more complicated than i 3.x. There are quite a few examples here:
http://help.sap.com/saphelp_nw70/helpdata/en/43/ef05462480025ae10000000a1553f7/content.htm
I used it in a case where I wanted to embed a Web template in a BPS application and pass characteristic filters from the BPS application to the web template - similar to your requirements. Basically you need the following just to restrict one characteristic :o(
&BI_COMMAND_1-BI_COMMAND_TYPE=SET_SELECTION_STATE
&BI_COMMAND_1-TARGET_DATA_PROVIDER_REF_LIST-TARGET_DATA_PROVIDER_REF_1=DP_1
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-SELECTIONS-SELECTION_1=SELECTION_INPUT_STRING
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-SELECTIONS-SELECTION_1-SELECTION_INPUT_STRING=PDS06
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-CHARACTERISTIC=0D_PH2
I could only get it to work with one characteristic and I suspect, that the reason is that the URL simply gets to long (very quickly). You have to repeat the above for every characterstic you want to use :o(

Custom button in alv and disabling all buttons in application tool bar

Experts,
Could you please help me for the below requirements.
1). How to disable all the buttons (like sorting, print, find, set filter...etc.) in tool bar using oops?
2). Where can I add my custom download button in alv report using oops?
Thanks in advance...
Sridhar..

Step1:
Create on local class
Class <LCL_EVENT_RECEIVER> Definition
Define the below public methods.
Method Name     HANDLE_TOOLBAR
Event Name     TOOLBAR
Event Class     CL_GUI_ALV_GRID
Importing     E_OBJECT, E_INTERACTIVE
Method Name     HANDLE_USER_COMMAND
Event Name     USER_COMMAND
Event Class     CL_GUI_ALV_GRID
Importing     E_UCOMM
Class <LCL_EVENT_RECEIVER> Implementation
.     Method HANDLE_TOOLBAR
     Declare the structure <LS_TOOLBAR> of structure type STB_BUTTON
     Append the button information as given below into table E_OBJECT->MT_TOOLBAR to         display the custom button on ALV grid.
                           LS_TOOLBAR-FUNCTION = u2018DOWNu2019
                     LS_TOOLBAR-QUICKINFO = u2018downloadu2019
                     LS_TOOLBAR-TEXT = u2018downloadu2019
     Method HANDLE_USER_COMMAND
In this method if E_UCOMM = u2018DOWNu2019 write your logic.
Step2:
1.     To excluding the ALV grid buttons, fill the <LT_EXC> with function code CL_GUI_ALV_GRID=>MC_FC_EXCL_ALL
2.     To generate the ALV Grid, call the method SET_TABLE_FOR_FIRST_DISPLAY
Class     CL_GUI_ALV_GRID
Method Name     SET_TABLE_FOR_FIRST_DISPLAY
Exporting
I_STRUCTURE_NAME      ZDS_CM_EXT_SEL
LS_LAYOUT                    <LS_LAYOUT>
IT_TOOLBAR_EXCLUDING     <LT_EXC>
Changing
IT_OUTTAB                    <GT_EXT_SEL>
Create the Instance for class <LCL_EVENT_RECEIVER>
Class     <LCL_EVENT_RECEIVER>
Instance Name     <LO_EVENT_FNAME>
Now set handler <HANDLE_USER_COMMAND> and <HANDLE_TOOLBAR_FNAME> events using instance <LO_EVENT_FNAME>
Call method 'SET_TOOLBAR_INTERACTIVE' to raise event TOOLBAR
Class     CL_GUI_ALV_GRID
Instance Name     <GO_GRID>
Method Name     SET_TOOLBAR_INTERACTIVE

Need for a Datagrid with variableRowHeight="true" and custom Item Renderer to display exact rows

Hi again, developers:
I'm in a search of a datagrid with certain characteristics:
     - variableRowHeight = "true"
     - only one column
     - each row must have a custom item renderer with possibly different heights, and a fixed width
     - the datagrid must show always every item in the data provider with no vertical scroll bars, what means that the datagrid height must have always the exact height sum of all the item renderers it is displaying.
     - and no extra empty rows must appear in the last positions of the datagrid
The last two requirements are something difficult to achieve... for some reason, empty rows appear at the last positions of the datagrid. I post what i've managed to get:
<mx:Script>
     <![CDATA[
     private function resize():void
                if (dg.dataProvider)
                    var h:Number = dg.measureHeightOfItems( -1, dg.dataProvider.length);
                    dg.height = h;
     ]]>
</mx:Script>
<mx:DataGrid id="dg" width="530" horizontalCenter="0" verticalScrollPolicy="off"
        dataProvider="{dp}"
        wordWrap="true" variableRowHeight="true" showHeaders="false" dataChange="resize()" height="{dg.measureHeightOfItems(-1,dg.dataProvider.length)}" click="Alert.show(dg.rowCount.toString());">
        <mx:columns>
            <mx:DataGridColumn headerText="ID" width="50">
                <mx:itemRenderer>
                    <mx:Component>
                        <mx:TextArea height="{Math.random()*100}" wordWrap="true" backgroundColor="{Math.random() * 16777216}" paddingTop="0" paddingBottom="0"/>
                    </mx:Component>
                </mx:itemRenderer>
            </mx:DataGridColumn>
        </mx:columns>
    </mx:DataGrid>

Thanks Harui, but it doesn't help. If the border is set it will help, but the very big problem is the empty rows that appear at the end of the datagrid... I can't find a way of measuring correctly the height of the itemRenderers!
I'll update this thread if I manage to do it.

Custom button skin with scaleGrid 9 slice image does not appear in Design Mode

So in a custom button skin I have a nine sliced image, and then throw that onto an MXML page. In design view, I cannot get the component to show the image that I've thrown on it. Unless I do a hack on the MXML page by adding the image in it's scaleGrid form to the page somewhere. Then it seems to act as like a preloader for the image so it actually displays. But I don't want to do this hack on every page that uses this component. Is there a work around?
Here's the button skin:
<?xml version="1.0" encoding="utf-8"?>
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
                    xmlns:s="library://ns.adobe.com/flex/spark"
                    width.disabled="296" height.disabled="73">

<fx:Metadata>
                    [HostComponent("spark.components.Button")]
                    [Embed('assets/art/shared/[email protected]', scaleGridTop=20, scaleGridBottom=85, scaleGridLeft=40, scaleGridRight=60)]
</fx:Metadata>

<s:states>
                    <s:State name="disabled" />
                    <s:State name="down" />
                    <s:State name="over" />
                    <s:State name="up" />
</s:states>
          <s:Group width="100%" height="100%" >
<s:Image width="100%" height="100%" smooth="true" source="@Embed('assets/art/shared/[email protected]', scaleGridTop=20, scaleGridBottom=85, scaleGridLeft=40, scaleGridRight=60)"/>
</s:Group>

          <s:Label id="labelDisplay" left="10" right="10" top="2" bottom="2" horizontalCenter="0"
                               maxDisplayedLines="1" textAlign="center" verticalAlign="middle" verticalCenter="1"
                               color="#FFFFFF" >
<s:filters>
                              <s:DropShadowFilter distance="0" angle="90" color="0x000000" alpha="1" blurX="2" blurY="2" strength="16" quality="3" />
</s:filters>
</s:Label>
</s:Skin>
And then I throw that button into an MXML page. The image doesn't show up in design view.
<s:Button x="330" y="94" width="134" height="57" label="Button" skinClass="features.shared.NineSliceButtonSkin" />
This hack, fixes the button! And all other buttons that use that skin.
<s:Image width="100%" height="100%" smooth="true" source="@Embed('assets/art/shared/[email protected]', scaleGridTop=20, scaleGridBottom=85, scaleGridLeft=40, scaleGridRight=60)"/>
<s:Button x="330" y="94" width="134" height="57" label="Button" skinClass="features.shared.NineSliceButtonSkin" />

Looking for an answer too!

How to disable the custom button on alv?

Hi All,
                   i created a ALV Report .I created a Custom Button on ALV.Based on the input value i need to enable/disable that Button.
How can i achieve?And what are the methods i need to code?
Regards
Ravi

Hi Ravi,
   You create the button like this:
Data: mr_functions type ref to IF_SALV_WD_FUNCTION_SETTINGS,
         mr_button_func type ref to CL_SALV_WD_FUNCTION
mr_functions ?= mr_alv_model.
CALL METHOD mr_functions->create_function
    EXPORTING
      id    = '<<Button Id>>'
    RECEIVING
      value = mr_button_func.
CREATE OBJECT mr_button.
mr_button->set_text( 'some text' ).
mr_button_func->set_editor( mr_button ).
to sent enable/disable
mr_button->set_enabled(abap_false).
hope this will serve your purpose.

Ritwik.

Custom validation is disabling submit button

Hi there,
I am using the update/insert feature within ADDT, but wanted to use my own validation using JavaScript. Everything works fine, the validation pop-up works etc, but the submit button is disabled. I'm guess that the transaction has started with the ADDT, but the javascript has stopped it. How can I get around this? any suggestions welcome...
Thanks in advance...

Hi,
Have you tried different browsers to double check. I remember a couple months ago I was helping someone with a similar problem, it worked in one browser fine but not the other so we had to rewrite the code. Initially the code looked fine but just didnt work in IE.

Finally, I have my cell renderer working fine (it was simpler than I thought). Anyway, I'm suspecting something is not working quite well yet. When I try to reorder my colums (by dragging them) they move like slow motion. If I don't register my custom cell renderer, I can move my columns fine. Next is the code of my custom renderer.
class PriorityRenderer extends DefaultTableCellRenderer {
public Component getTableCellRendererComponent(
JTable table, Object value,     boolean isSelected,
boolean hasFocus, int row, int column) {
    if(value instanceof coloredValue) {
    coloredValue cv = (coloredValue)value;
    if(isSelected) this.setBackground(table.getSelectionBackground());
    else this.setBackground(cv.getbkColor());
    this.setForeground(cv.gettxColor());
    this.setText(value.toString());
    this.setOpaque(true);
    return this;
}All the cells of my JTable are "coloredValue"s. This is a little class with a String, two colors and some getter methods.
Can anyone giveme a hint ?
Thanks!!

OK! Now the performance problem is gone!! (I don't know why, I didn't touch a thing)
Thanks anyway

Help with JTreeTable custom cell renderer!

Hi.
I've followed diligently the complete TreeTable2 example found on the Sun site. http://java.sun.com/products/jfc/tsc/articles/treetable2/
What I'm trying to do is to add alternate-row shading on the Column(0) of the JTreeTable where the Column class is "TreeTableModel".
so, from the example, I've added the following setCellRenderer declaration to TreeTableExample2.java:
     protected JTreeTable createTreeTable() {
          JTreeTable       treeTable = new JTreeTable(model);
          treeTable.getColumnModel().getColumn(1).setCellRenderer
          (new IndicatorRenderer());
          treeTable.getColumnModel().getColumn(0).setCellRenderer
          (new MyTableCellRenderer());Then, I subclass DefaultTableCellRenderer as shown below, in a new class called "MyTableCellRenderer"
import java.awt.Color;
import java.awt.Component;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;
public class MyTableCellRenderer extends DefaultTableCellRenderer implements TableCellRenderer
     private static final long serialVersionUID = 1L;
     public MyTableCellRenderer() {
     public Component getTableCellRendererComponent(JTable jtable, Object obj, boolean isSelected, boolean hasFocus, int i, int j)
          if (i % 2 == 0 && !isSelected) {
               this.setBackground(new Color(214,226,255));
               this.setForeground(Color.BLACK);
          } else if (isSelected)
               this.setBackground(new Color(204, 204, 255));
          else {
               this.setBackground(Color.white);
          //if (obj != null)
          this.setValue(obj.toString());
          System.out.println("obj: " + obj.toString());
          System.out.println("obj type: " + obj.getClass().getName());
          return ((Component) (this));
}I've been pulling out whatever few hairs I have left in my sparse scalp to get this working, but it's looking grim thus far.
Here are links to screenshots of my progress, or lack thereof:

thanks again - !!

phew! finally got this sucker working. I had to retrieve the default rendererer of my TreeTable's TreeTableModel class column, which is the JTree and then, in its component-form, start mucking about with its stylings. The real black-hole of progress was caused by my brain imploding from not being able to understand that a "Component" was what represented the "thing" whose behaviour I wanted to alter, be it a Jtree node or Jtable cell.
          treeTable.getColumnModel().getColumn(0).setCellRenderer(new TableCellRenderer() {
               public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
                    Component comp = treeTable.getDefaultRenderer(TreeTableModel.class).getTableCellRendererComponent(table, value, isSelected, hasFocus, row, col);
                    if (row % 2 == 0 && !isSelected) {
                         comp.setBackground(new Color(214,226,255));
                         comp.setForeground(Color.BLACK);
                    } else
                         if (isSelected)
                              comp.setBackground(new Color(204, 204, 255));
                         else {
                              comp.setBackground(Color.white);
                    return comp;
          });In all of its ravishing glory:

Using social media share codes with custom buttons

Is there a way to use custom buttons/icons for social media share, like, etc..? I have tried inserting the html with no luck. The canned social widgets don't really match the look of the site I am designing.

Facebook doesn't allow changing that. Refer to their Guidelines with Do's and Don'ts here - https://www.facebookbrand.com/guidelines?asset=5&media=1,2,3&platform=
Thanks,
