Specific Model not showing rows in a table in a column of a table
Hello,
Fairly simple issue here (I think):
I have a table bound to a global model and its rows bound to "/items"
I then have a column within that table which has a valuehelpfield that pops open a dialog with a table.
This tables rows inside the dialog are bound to a temp model. Now I know this temp model has the correct data and format and I do not get a "no data" messages when I bind it's rows to the node on the temp model, and to double check that I tried binding it to an incorrect node and it did say "no data" and I tripple checked by getting the jsonstring of the model and it's exactly how it should be.
Here is the code:
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({
text: "Shop",
required: true
width: "200px",
template: new sap.ui.commons.ValueHelpField({
value:"{shopdesc}",
valueHelpRequest: function(oEvent){
var locModel = oTable.getModel();
var rowContextPath = oEvent.getSource().getBindingContext().getPath();
var oRowObj = oEvent.getSource().getBindingContext().getObject();
var oDataOld = sap.ui.getCore().getModel().getData();
var tempModel = new myJSONModel;
tempModel.setData({
shops: []
sap.ui.getCore().setModel(tempModel, "tempModel");
tempModel = sap.ui.getCore().getModel('tempModel');
d = tempModel.getData();
arr = d.shops;
var shops = oDataOld.shops;
for (var i = 0; i < shops.length; i++) {
if (shops[i].area == oRowObj.area) {
arr.push(shops[i]);
var oValueHelpDialog = new sap.ui.commons.Dialog(
{ modal: true,
title: "Select a Shop",
closed: function (oEvent) {
var oContext = oTableJobs.getContextByIndex(oTableJobs.getSelectedIndex());
if (oContext) {
var oSel = oContext.getModel().getProperty(oContext.getPath());
locModel.setProperty(rowContextPath + "/shop", oSel["shop"]);
locModel.setProperty(rowContextPath + "/shopdesc", oSel["shopdesc"]);
var oTableJobs = new sap.ui.table.Table({
visibleRowCount: 15,
firstVisibleRow: 1,
selectionMode: sap.ui.table.SelectionMode.Single,
width : "300px"
var oOkButton = new sap.ui.commons.Button({
text: "OK",
press: function (oEvent) {
oEvent.getSource().getParent().close();
oTableJobs.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "shop"}),
template: new sap.ui.commons.TextField().bindProperty("value", "shop"),
editable:false,
width: "100px"
oTableJobs.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Shop Description"}),
template: new sap.ui.commons.TextField().bindProperty("value", "shopdesc"),
editable:false,
width: "300px"
var jsonString = tempModel.getJSON();
alert(jsonString);
oTableJobs.bindRows("tempModel>/shops");
oValueHelpDialog.addButton(oOkButton);
oValueHelpDialog.addContent(oTableJobs);
oValueHelpDialog.open();
var oModel = sap.ui.getCore().getModel();
oTable.setModel(oModel);
oTable.bindRows("/items");
Any help would be appreciated, I can't see what's wrong here, all seems fine to me! Thanks!
HI Bob
I briefly scan thru your code and spotted one common issue. When we are binding property, we need to include the model name. e.g.
template: new sap.ui.commons.TextField().bindProperty("value", "shop"),
should be
template: new sap.ui.commons.TextField().bindProperty("value", "tempModel>shop"),

WPF: How to make the first column does not show row separator and Left column separator in DataGrid?
Our WPF application uses DataGrid.
One of request is that first column of DataGrid does not show row separator and also does not show Left column separator. So it looks like the first column does not belong to the DataGrid. However, when select a row, the cell of first column still get selected.
How do we make it? Thx!
JaneCHi Magnus,
Thanks for replying our question and provide your solution!
Your solution works by setting "HorizontalGridLinesBrush" and "VerticalGridLinesBrush" to {x:Null} in the DataGrid style and modify "CellStyle" in first column as following:
<DataGridTextColumn MinWidth="32"
Binding="{Binding CellName}"
CanUserReorder="False"
CanUserSort="False"
Header="Cell}"
IsReadOnly="true" >
<DataGridTextColumn.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="IsEnabled" Value="False"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border BorderThickness="0" BorderBrush="{x:Null}"
Background="{Binding Background, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Margin="-1">
<Grid Background="{TemplateBinding Background}" VerticalAlignment="Center" Height="42">
<ContentPresenter VerticalAlignment="Center"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGridTextColumn.CellStyle>
</DataGridTextColumn>
We found another way to achieve it by using DataGridRowHeader. The good way to use DataGridRowHeader is that we do not need to make the first column ReadOnly (click on first column does not select whole row anymore). Select RowHeader in a row will select
whole row. Move scroll bar horizontally, the row header still keep in visible area.
<Style TargetType="{x:Type DataGridRowHeader}" x:Key="dataGridRowHeaderStyle">
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="HorizontalAlignment" Value="Center" />
<Setter Property="Height" Value="42" />
<Setter Property="SeparatorBrush" Value="{x:Null}" />
<Setter Property="FontSize" Value="16" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridRowHeader}">
<Grid>
<Border x:Name="rowHeaderBorder"
BorderThickness="0"
Padding="3,0,3,0"
Background="{Binding Background, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"
BorderBrush="{x:Null}">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<DataGrid>

I am trying to sync my ipad3 to my itunes on a pc laptop, the ipad does not show up in the itunes left hand column. an ipod is already synced to the itunes. any suggestions welcome
Hi lindaasw,
Welcome to the Support Communities!
Do you have the latest version of iTunes for Windows installed? I would turn on the sidebar and the menu bar just to make sure you are seeing everything. If the iPhone is still not recognized in iTunes, follow these troubleshooting steps:

JTable Problem (table does not show rows and columns)
Hi All,
What the table is suppose to do.
- Load information from a database
- put all the values in the first column
- in the second column put combobox (cell editor with numbers 1-12)
- the 3rd column put another combobox for something else
- the 4th column uses checkbox as an edit
The number of rows of the table should be equal to the number of
record from
the database. If not given it default to 20 (poor but ok for this)
The number of columns is 4.
But the table does not show any rows or
column when I put it inside a
JScrollPane (Otherwise it works).
Please help,
thanks in advance.

Specific model not picking up advertisements
The other week I went to add the Powershell module to our Boot Images
We encountered an error trying to do that, so we gave up, and built new boot images just to be safe.
After doing so, and triple checking everything was exactly as had been previously, we now have one specific model of computer that won't pick up advertisements.
We have repeatedly confirmed the computer entry is in the collection, we have removed and re-added the computer and re-added it to the collection, yet it still will not pick up the advertisement. We have done this multiple times with multiple computers of
the same model, all with zero success.
I give up. Hive-mind, help!Hello,
Have you verified smbios UUID of these computers?
Someone else have encountered duplicate UUID which caused PXE boot issue.
http://social.technet.microsoft.com/Forums/en-US/7702e267-6c1a-4844-9a2b-2347137b17e3/os-deployment-task-sequence-doesnt-show-up?forum=configmanagerdeployment
So these computers may became known computers. -
Best approach to publish new table or new column on existing table on MDW?
Hi,
I'm refering to Olite R3 without any patches. I don't use Java API, I use MDW.
if I have a new table or a new column on a existing table, what's the best approach to publish it?
I'm asking this because I've trying lots of approaches and the only solution was, step-by-step:
1) On MDW, drop the publication item
2) Add again the publication item
3) Associate the publication item to the publication
4) Save everything
5) File / Deploy (if I don't do it, it does not work)
6) Tools/Package... (that's where it's a problem: if I don't remove the app and create it again it does not work!)
7) on the client side, I perform a msync with "force refresh"
That's the only way I found to publish new items for sure. Any other action does not push the new table or new column to the client's embbeded DB.
Any comments?
Regards,
Maurício Américo Vernaschi.I do not use MDW, rather a mix of java and the final publish step you use, but
Adding new PIs should be easy, just add them and re-publish (no need to drop anything)
for changes, if you just have new columns and the sql statement is 'select * from' then you should just need to make the changes in the base schema objects, and run the publish with no changes and the updates should be picked up. If selecting specific columns, then update and re-publish.
When using MDW at the end you can save the application as a jar file, and then use this jar file to publish in the mobile manager - this is the best wayto publish.
Have a look at this jar file in winzip, and you will find it contains a web.xml file. This is the xml definition of the publication items, and for simple changes it is possible to just edit this file and republish via the mobile manager -

JTable with custom column model and table model not showing table header
Hello,
I am creating a JTable with a custom table model and a custom column model. However the table header is not being displayed (yes, it is in a JScrollPane). I've shrunk the problem down into a single compileable example:
Thanks for your help.
import javax.swing.*;
import javax.swing.table.*;
public class Test1 extends JFrame
public static void main(String args[])
JTable table;
TableColumnModel colModel=createTestColumnModel();
TestTableModel tableModel=new TestTableModel();
Test1 frame=new Test1();
table=new JTable(tableModel, colModel);
frame.getContentPane().add(new JScrollPane(table));
frame.setSize(200,200);
frame.setVisible(true);
private static DefaultTableColumnModel createTestColumnModel()
DefaultTableColumnModel columnModel=new DefaultTableColumnModel();
columnModel.addColumn(new TableColumn(0));
return columnModel;
static class TestTableModel extends AbstractTableModel
public int getColumnCount()
return 1;
public Class<?> getColumnClass(int columnIndex)
return String.class;
public String getColumnName(int column)
return "col";
public int getRowCount()
return 1;
public Object getValueAt(int row, int col)
return "test";
public void setValueAt(Object aValue, int rowIndex, int columnIndex)

See http://download.oracle.com/javase/6/docs/api/javax/swing/table/TableColumn.html#setHeaderValue(java.lang.Object)
When the TableColumn is created, the default headerValue is null
So, the header ends up rendered as an empty label (probably of size 0 if the JTable computes its header size based on the renderer's preferred size).nitpicking (can't resist - the alternative is a cleanup round in some not so nice code I produced recently <g>):
- it's not the JTable's business to compute its headers size (and it doesn't, the header's the culprit.) *> - the header should never come up with a zero (or near-to) height: even if there is no title shown, it's still needed as grab to resize/move the columns. So I would consider this sizing behaviour a bug.*
- furthermore, the "really zero" height is a longstanding issue with MetalBorder.TableHeaderBorder (other LAFs size with the top/bottom of their default header cell border) which extends AbstractBorder incorrectly. That's easy to do because AbstractBorder itself is badly implemented

JeanetteNo problem, thanks for the insight :) -
EntityBeans does not show row update.
Hello,
I make an EntityBean
I make a EntityFacade SessionBean for it.
I make a servlet that through EntityFacade call the findAll() method..
When I run the servlet, it show the row contained in the EntityBean correspondent Database Table.
When I add a row in database table and refresh the servlet browser page, the new row appear in a browser.
When I update a field row in database table and refresh the servlet browser page, the update does'nt appear in a browser.
Why?What is cached?Well, I'm not sure if this would be the best approach, but you could create a servlet and send to that servlet the ID of the entity bean you just modified; in the servler (preferably using a session facade or business delegate) :
1. find the entity bean (EntityManager find())
2. refresh the entity bean (EntityManager refresh()) -
Why are some of my tracks in specific playlists not showing up in my Music Library playlist?
I've restarted several times and some tracks that are in certain playlists don't show up on my music library playlist. Is this a bug? Any known fix? Thx!
But I would think that the purchases would be saved onto my Itunes account and therefore redownload into my computer. I have been able to retrieve about 9 of the 20+ songs that I bought by syncing my phone however the other purchases are still not there. Also, when I go to the Itunes store and back to the purchases, the button you press to buy it says "PURCHASED" so I know I don't have to rebuy them. How do I redownload the music I purchased previously?

SAP ProComp model not showing up in ID
Hello,
I have created a model of type "SAP ProComp model " in ESB. Now when I try to use this as template while creating a Configuration Scenario in ID, I do not see it.
I am trying to locate it under "SAP Process Component Interaction Model".
But when I create a model of type "SAP ProComp Interaction model", I am able to see it.
This seems logical, but I am able to see SAP provided models of type "SAP ProComp model" here.
I am on PI 7.1 EHP1.
Please advise.
Thank you.Is it because SAP Pro Comp model is not supported in EHP1. Now I tried creating my own SAP Pro Comp Interactive Model and when I try to load that, I get the below errors.
Process Component Interaction Model 'XXX': Error in reading Process Component object definition - set name and ID to null and type to internal
Please advise.
Thank you. -
DAE models not showing in PS/CS4
I'm importing DAE from Google 3D warehouse. I can see the layer data, and the model data in the 3D panel. The move handles appear. But I see no model.
I have seen in a couple of places where the Materials Opacity needs to be reset to 100%. But even after doing this the model is still not visible.
Please see attached GIF for reference.
Thank you!Does the 3D hierarchy (leftmost button in the 3D panel) list any mesh items? Please check. the thing being a butterfly I also get the feeling that all it ever was is just some textured planes, so there won't be much geometry to begin with....

Events before a specific date not showing up on Calendar List View
I used to be able to view events as far back as they go in Calendar's List View. Since upgrading to iOS 7, I can't see events before September 23, 2012 in the List View (by pressing Search icon). Is it because there technically is no longer a List View in the new iOS 7? I'm confused why 9/23/2012 was selected as the cutoff date.

When I look at my icloud calendar on my MAC, everything is there... when I go to my iPhone or iPad... the timed events are missing. The all day events do show up? HELP?
Duplicates are due to syncing both with iCloud AND with iTunes. Turn off calendar syncing in iTunes.
I don't know what you mean by "removed some from my mibile devices". Are you sayig some calendars are gone on some devices that have been registered with iCloud? -
Finder does not show EPS PICT or TIF previews in column view in 10.4
It seems in the upgrade between 10.3 and 10.4 they dropped the ability to see the low res PICT or TIF image that is stored in the EPS file. In other apps, InDesign, Quark I can see it in column view open dialogue box but no such luck with Finder windows.
I have seen the question on a few other forums but there has been no satisfactory answer to this question. I can't just use AI files and make them PDF compatible either, which is what I have been hearing as a common workaround. As of now I have been using EPSwizard:
http://www.jolauterbach.com
It used to be free but now it is a pay version. If anyone wants the older free app reply to me and I can give it to you. It is a decent solution until I can find someone who knows how to tweak the finder to see these again.
My best guess that Mac didn't want to show a low res image in their pretty OS so they deep 6'ed it in the 10.4 version. I am pretty sure that it is just not reading the resource/data fork where that image is contained. It would make my life so much more enjoyable if I didn't need to load an app everytime I want to see what an EPS file looks like inside.
If anyone can clue me in on a tutorial on how to change this let me know.
Power Mac G5 1.6GHz Single Mac OS X (10.4.7)These files are EPS files not image files. They have a TIF or PICT preview inside the file, I believe in the resource or data fork of the file. The file extension is EPS, and I cannot change that, just type the letters. The actual extension, the 4 digit one, that is invisible is the one that is important. In the case of EPS the actual extension is EPSF or EPSI.
Just to try the fix I changed the name and it did try to make a preview, but it came up with nothing. It was blank in column view. The OS still reads it as an EPS regardless of the change in file extension.
Anyone have some answer that involves a command line, I think that is really going to be the only thing that solves this one.
