TableView Singleinterval selection

Hi,
I asked the same question on Stackoverflow but I got no answer so maybe I'll be more lucky here. Is there a way to set the achieve a single interval selection in a TableView? I digged into the code for days now and I'm pretty sure the answer is no, so my second question is, is there a plan to add it?
Thanks

To be more specific I'm talking about rows selection and what in Swing was SINGLE_INTERVAL_SELECTION, from the docs "select one contiguous range of indices at a time".

TableView user selection disappear

Hello,
I have problem with using TableView.
I'm using JSPDynPage. I have there method: "public void onRowSelection(Event e)" and in jsp corresponding method registering in TableView for selection event.
My method onRowSelection is called successfully, but table selection indicator disappears after click-release. I put in my onRowSelection method this code:
TableView table = (TableView) this.getComponentByName("tv1");
table.selectRow(aRow, true);
.. but nothing changes. I guess, there must by some possibility to change TableView's model selection, but I can't find it in API.
Best Regards,
Josef Motl

Hi Josef,
Create methods in your bean class setting and getting a TableView (setOldTableView(), getOldTableView()). Then in the doProcessAfterInput() method, put the following code:
TableView table = (TableView) this.getComponentByName("tv1");
bean.setOldTableView(table);
In your JSP put the following with your tableView:
<% tv1.useRowSelection(bean.getOldTableView()); %>
The following is from the Javadoc for TableView:
useRowSelection
public void useRowSelection(TableView table)
select the rows in this table, using the same indexes of the rows which were selected in the table.
Parameters:
table - the indexes of the selected rows in the table will be used to determine which rows of the actual table object should be (pre)selected.

TableView item selection problems

Detlev, if you are out there, please help!
I have been trying to follow the doc and examples for selecting an item in a TableView. I have got the event to fire, but there is no such event as TableSelectionEvent, instead you must use TableRowSelectionEvent.
Also, this does not have the promised getRowIndex() method. The javadoc say you can get the selected row from Event.getParams(), but this returns null!
Furthermore, SAP have a working example of selecting TableView rows and keeping the selection, but the code samples cannot possibly be from the working example.

Hi Martin,
just in addition to Brian's answer, see How to use onRowSelection !!!! for further discussions - and with that, maybe you'll like the idea of using search functionality of SDN
And if you ask that directly for my help --- please give some respect to my ending notes on How to create datasource alias in EP project? ... Your misfortune is that I have a quite good memory...

TableView: selectedRowKey=" %=selected% " fails when null

Hello,
having a HTMLB:TableView and the key column being PersNo (a NumC 8) it is not possible to define an unselected state for my table view when using the selectedRowKey attribute:
selectedRowKey="0" or selectedRowKey="00000000"
works fine, but as soon as this is a variable of the same type as the key column
selectedRowKey="<%=selected%>"
is get an exception claiming that the key value does not exists.
Yes, and this is right, because there may be initial states where the selected row is not defined. If the "selected" thingy is filled with an existing key, it works fine.
Of course cannot simply alternate using an inline IF cos that is not possible within attributes and leads to compiler error when doing an IF-ELSE-ENDIF around the entire htmlb:tableView element (not well-formed; tag must be closed) - one that contains selectedRowKey and one one not; depending on an initial "selected".
Any ideas why using a variable fails but not specifying the same value manually in HTMLB? Or better: what is the solution to get it working for me?
Thanks and regards,
Timo

Hello Durairaj,
Yes, that was the solution. I played with the leading zeros before but forgot that the NumC will revert to its defaults.
So, I now use a String that I fork in the frontend:
if the passed NumC is greater than 0 I move it over, otherwise, I manually set '0'.
That works, although it is interesting to see that the selectedRowKey var I use is of the same type as the tables key column type
Thanks all!
Regards,
Timo

Problems loading text to xib using plist in tableview's selected cell

I am developing an app that starts with a grouped tableview cell. Each cell has an image, text, and description from a plist. When a cell is chosen a xib is loaded by a view controller in the plist. I want to load into the xib some text, an image, and a sound file that is in the plist (dict for that cell). This way I don't have to have lots of view controllers and xibs. I have been able to load the xib using this method but I can't get the images and text to load. I have been able to do it when I don't have a grouped table view but when I add the grouping in the plist the connection is lost. below is my code. Could someone look at it and tell me where I've gone wrong, how to correct it, or another way to do what I want to do?
I know I am not calling the right array and then dictionary but I don't know how to correct this. Help please.

specifically the underlined part. does this need modifying or completely rewritten.

Alert with TableView: (eg: select a wifi network)

Can someone please point me in the right direction of implementing an alert window containing a table view?
The only example I can think of is when you open Safari (without a known WiFi network). This shows an alert window containing a list of available WiFi networks. You can scroll and select one.
Thanks

Hi,
In order to see what i'm talking about do the following:
1) Make sure you have a WiFi Connection
2) Go into WiFi and click the little blue icon next to your connection
3) Select "forget this network"
4) You should now have lost your WiFi connection
5) Make sure your GPRS connection isn't active (modify username / password etc)
6) Open Safari and it should struggle to load the page
7) It will then display an Alert Window containing a scrollable table view where you can choose a WiFi network to connect too.
This is what i'm trying to achieve.
Thanks

B10 build TableView row selection causes columns to stretch out of order

When running the following css on a tableRow to change the selected highlight colour. If you have 50 of more rows and need to use the arrow keys to scroll the columns become stretched and out of order
.table-view .indexed-cell .cell: selected {
-fx-border-color: #f8c27f;
-fx-background-color: rgb(230,230,230);
}

Could you please post a bug in the JavaFX Jira at http://javafx-jira.kenai.com. If you file it under the 'runtime' section against the 'controls' component, it will be looked at as soon as possible. Ideally you'd include a small test application as an attachment.
Thanks!

Setting tableView selection

I have a htmlb:tableView with selection.
I now implemented a "Move-Up" button, by which you can move the selected line one line up. This works fine.
If you select line 5, it will be moved to line 4.
However, the tableview selection stays at line 5 after the move. I can I move it to line 4. In other words, how do I set the tableView selection via coding?

Hi Daniel,
there are 2 ways dependent on how your table is defined.
If you are using Index you need to set one of the attributes selectedRowIndexTable or selectedRowIndex (dependent on whether you use single or multi-select). Be aware if you delete the selection you need to set this value to an invalid Index as otherwise the tableview reads it from the request.
If you have defined a key column you basically do the same but use the attributes selectedRowKeyTable or selectedRowKey. Here the same applies if you want to delete(unselect) the entry.
Best Regards
Michael

How can I get an instance of my customize cell in tableview?

Hi,I'd like to generate a customize tablecell in my tableview.but How can I get an instance of my customize cell in tableview when selected item changes?
public class Person {
 private javafx.beans.property.BooleanProperty active;
 private StringProperty firstName;
 private StringProperty lastName;
 private StringProperty email;
 private Person(String fName, String lName, String email) {
 this.active = new SimpleBooleanProperty(true);
 this.firstName = new SimpleStringProperty(fName);
 this.lastName = new SimpleStringProperty(lName);
 this.email = new SimpleStringProperty(email);
 public javafx.beans.property.BooleanProperty activeProperty() { return active; }
 public StringProperty firstNameProperty() { return firstName; }
 public StringProperty lastNameProperty() { return lastName; }
 public StringProperty emailProperty() { return email; }
final ObservableList<Person> data = FXCollections.observableArrayList(
 new Person("Jacob", "Smith", "[email protected]"),
 new Person("Isabella", "Johnson", "[email protected]"),
 new Person("Ethan", "Williams", "[email protected]"),
 new Person("Emma", "Jones", "[email protected]"),
 new Person("Michael", "Brown", "[email protected]")
public class RatingCell extends TableCell<Person,String> {
 private NabiSyncRating rating;//NabiSyncRating is a customize control.it has some method ,like change backgroud-color,value,etc.
 public RatingCell() {
 rating = new NabiSyncRating(-1);
 @Override
 public void startEdit() {
 super.startEdit();
 if (isEmpty()) {
 return;
 rating.setDisable(false);
 rating.requestFocus();
 @Override
 public void cancelEdit() {
 super.cancelEdit();
 rating.setDisable(true);
 public void commitEdit(String value) {
 super.commitEdit(value);
 rating.setDisable(true);
 @Override
 public void updateItem(String item, boolean empty) {
 super.updateItem(item, empty);
Callback<TableColumn<Person, String>, TableCell<Person, String>> ratingCellFactory = new Callback<TableColumn<Person, String>, TableCell<Person, String>>() {
 @Override
 public TableCell<Person, String> call(
 TableColumn<Person, String> p) {
 return new RatingCell();
TableColumn firstNameCol = new TableColumn();
firstNameCol.setCellFactory(ratingCellFactory);
firstNameCol.setMinWidth(100);
firstNameCol.setMaxWidth(224);
firstNameCol.setResizable(true);
tableView.getColumns().addAll(firstNameCol);
tableView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
 @Override
 public void changed(ObservableValue observable, Object oldvalue, Object newValue)
 Person person=(Person)newValue;
 //I'd like to get the instance of my customize control 'RatingCell' ,How can I get the RatingCell instance which in current row?
 System.out.println("selected row is : " + newValue );
 });

HI,
I have found a solution to find it
First ,you need to set person property 'id' as the input parameter for your customized component method 'public void updateItem(String item, boolean empty)'
ratingCol.setCellValueFactory(new PropertyValueFactory<Person,String>("id"));
firstNameCol.setCellFactory(ratingCellFactory);and then you need to implement your customize component like this:
import javafx.scene.control.ContentDisplay;
import javafx.scene.control.TableCell;
public class RatingCell extends TableCell<Person,String> {
 private NabiSyncRating rating;
 public RatingCell() {
 rating = new NabiSyncRating(5);
 this.setGraphic(rating);
 this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
 this.setEditable(true);
 public void updateRating()
 if(rating!=null)
 rating.selectRating();
 @Override
 public void startEdit() {
 super.startEdit();
 if (isEmpty()) {
 return;
 rating.setDisable(false);
 rating.requestFocus();
 @Override
 public void cancelEdit() {
 super.cancelEdit();
 rating.setDisable(true);
 public void commitEdit(String value) {
 super.commitEdit(value);
 rating.setDisable(true);
 @Override
 public void updateItem(String item, boolean empty) {
 if(item!=null && item.length()>0)
 if(rating!=null)
 rating.setId("NR"+item);
 this.setId("NC"+item);
 super.updateItem(item, empty);
} and find the current like this :
tableView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
 @Override
 public void changed(ObservableValue observable, Object oldvalue, Object newValue)
 Person person=(Person)newValue;
 Set<Node> colNodes=tableView.lookupAll("RatingCell");
 for(Node nod:colNodes)
 System.out.println("person.email:"+"NC"+person.email.getValue()+"|nodId: " + nod.getId()+"\r\n" );
 if(("NC"+person.email.getValue()).equals(nod.getId()))
 System.out.println("get current instance" );
 ((RatingCell)nod).updateRating();
 });Edited by: noob on Apr 20, 2012 4:49 PM

Tableview problem when sort

Hi all,
We've implemented a tablewiew in MVC. The property sort is "SERVER". When a row of the tableview is selected an we try to sort the table, the selected row is lost.
How we keep the selected row when we sort the tableview?
Thanks in advance.

Hi Mario
   What is happening in case you are sorting the table is it is refreshing the selectedrowindex.
   If you want the same index to remain selected, you can do one thing, just save the selectedrowindex in some variable before sorting and assign that variable to selectedrowindex after sorting. It will show that index as selected.
   If you want the same item to remain selected. i.e. let you have selected index 5 and after sorting the item of index 5 move to 2, And now you want the same item which is now on index 2 , to be selected. Than you need to store the key values of that item in some variable before sorting and after sorting Loop through the table to get the index of that item having same set of KEY VALUES.
Now use that index to set the selectedrowindex value.
This will make that item selected.........
I think it will solve your problem, otherwise do revert back.........
Have a nice time..

Tableview,PREVSELECTEDROWINDEXTABLE.

Hi Guru's,
I am doing a small coding with tableview,multiple selection .
iam getting the data in the tableview and multiple selection is also wrking.
but my problem is when i select multiple options in the table view and click on the button which is below the table view i want to update that selected rows to one ztable.
so when i debug the code iam getting the multiple selected rows in
TV ?= CL_HTMLB_MANAGER=>GET_DATA(
              REQUEST = RUNTIME->SERVER->REQUEST
              NAME    = 'tableview'
              ID      = 'tv_output' ).
      TV_DATA = TV->DATA.      .
        READ TABLE LT_OUTPUT INTO WA_SELECTEDQUES INDEX TV_DATA->PREVSELECTEDROWINDEXTABLE.
            ENDIF.
    ENDIF.
here in this iam getting those rows TV_DATA->PREVSELECTEDROWINDEXTABLE.
but when i run the above code
it throws an error i,e
PREVSELECTEDROWINDEXTABLE. may not be convereted to number.
so pls help me out

Hi Bhavana,
The "read table" abap statement with index extension allows only a number / number type variable.
your variable "TV_DATA->PREVSELECTEDROWINDEXTABLE" is not of number time.
The "TV_DATA->PREVSELECTEDROWINDEXTABLE" type is a table type "INT4_TABLE".
So in order to read the row contents you need to loop at this table and put your read statement inside the loop.
For eg.
data: indx type int4.
loop at TV_DATA->PREVSELECTEDROWINDEXTABLE into indx.
READ TABLE LT_OUTPUT INTO WA_SELECTEDQUES INDEX indx.
"Use the WA_SELECTEDQUES to insert it into a db table.
endloop.
Hope it helps!

Unable to change singleton property of context parent node.

Hi
I am having a view context node structure as follows.
Root context Node
|__Parent
*****|__child 1
*****|__child 2
I have created a table view which is using above structure.
Now I have selected "Selection Mode" property of my table to "Multi", as i intend to select multiple rows in this table.
When i tried to run this application..I got following error :
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(TableView.Person): selection cardinality does not allow multiple selection
What i traced from this problem is that i have set "singleton" property of my "Parent" context node to "true".
But what if i wish to change it to "false"...
I AM UNABLE TO DO THAT !!
Please help me out.
Thanks in anticipation.
Edited by: Saurabh Agarwal on Jun 23, 2008 8:20 AM

Yes....
Now i changed my Selection property of my component context...
and that change was automatically reflected to my view context...
Actually what is happening..
if mapping to component context is set in view context..
then Properties could not be changed directly from view context.
Thanks all....for your help..
my problem is solved now....
Thanks...

Passing paramters and calling a PCUI screen from a BSP Application

Hi,
We have developed a custom BSP application which displays a list of Opportunities in a HTMLB table view based on a search criteria.
When I click on a particular opportunity no., I should call a PCUI screen which should display that particular opportunity details.
Any help is greatly apperciated.
Thanks,
Vasu.

You are going to have to be more specific in what you want.
First I would read the following pieces of info. They will help you with general problems, also with creating an Iterator and read the select rows of a table.
BSP Element - Dynamic tableView with Internal Table
<a href="/people/brian.mckellar/blog/2003/10/31/bsp-programming-htmlb-tableview-iterator">BSP Programming: HTMLB TableView Iterator</a>
Just shooting from the hip I am assuming you are clicking on a selected ROW in the tableView where you defined the tableView with selectionMode="SINGLESELECT" and onRowSelection="MySelectEvent" then on the OnInputProcessing Event Handler you read the selected row (see <a href="TableView and selected row)
So and of course once you read the selected row in the OnInputProcessing event handler you can do further porocessing.
However if you are wanting to provide the user with the ability to click an icon or text link in the row then please refer to the Iterator for that.

"Select All" in tableview does not trigger event?

Hi,
I have a MULTISELECT table, and whenever I use the "Select all" or "Deselect all" feature, I don't seem to be able to capture the resulting event... Whenever I select one line, there's always a "tableView" event being triggered, allowing me to run the following code to recover the selected entries:
me->check_groups = table_event->GET_ROWS_SELECTED(
includeCurrentSelectedRow = 'X' ).
However, when I select all entries, there's not even an event being generated:
event = CL_HTMLB_MANAGER=>get_event( request ).
if event is not initial...
endif.
The above code fails; no event seem to be generated!!
Have I missed out on something; or is this a bug...? I would assume the built-in "select all" would trigger some kind of event... or do we have to check/program this manually?
Trond

hi trond,
what i know is that for catching request u have to use runtime object.
so u may try this:
event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
might be possible it will solve your problem.

Problem with checkbox selection in Tableview

Hi All
I am using table view with 8 columns - in the last 4 columns i have checkboxes for user input - i have a strange problem - when the table has multiple entries - for the last column i can only select the checkbox on line 1 - and i cannot select the checkbox on the remaining entries below - but for the other colums with checkboxes this is not the case
The selection mode for the table is no line selection - since the table is already displayed with input enabled fields - this is to reduce the no of clicks for user
Can anyone point out what is going wrong - how can i fix this - what i am doing wrong ?
Thanks
Sen

Hi
When i click on the checkbox for the 2nd or 3rd rows of the last column - nothing happens - the checkox is still active but nothing happens -
this is the tableview code
<htmlb:tableView id = "Detail"
 design = "ALTERNATING"
 headerText = "Header Text"
 onNavigate = "onMyNavigate"
 emptyTableText = "test"
 onRowSelection = "onMyRowSelection"
 fillUpEmptyRows = "false"
 footerVisible = "true"
 visibleRowCount = "5"
 table = "<%= DETAILTAB %>"
 iterator = "<%= iterator %>" >
and this is the code for the last column
<htmlb:tableViewColumn columnName = "OBSOFLGICON"
 width = "3"
 type = "user"
 horizontalAlignment = "CENTER"
 title = "Obs" >
 <htmlb:checkbox />
 </htmlb:tableViewColumn>
Thanks
