Linktoaction cell editor
Hi Experts,
I have changed the existing column in a table(not alv) form a textview to linktoaction cell editor
I have assigned the type also as function in the properties and a text which leads to values.
The problem is it doesnt show the underline for the fields in that column.
The component result directly shows up as you execute from portal.
Can you please explain in detail whats the problem?
Are you sure you have assigned type function and not result ?
the different types you can assign just alter the formatting of the link to action - so using the type of result just shows text with no underlining.
[different types lead to different formatting|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/0f/e8884118aa1709e10000000a155106/frameset.htm]
Otherwise have you assigned an action to the UI element? - it won't show up as enabled unless there is actually an action defined.

Table with Linktoaction cell editor VS ALV with Link to action cell editor
Hi,
i am replacing table UI with ALV, i am encountering series of problems one of them is below.
when i click on linktoaction cell in table i can see wdevent has context_element which is element reference, which is being used in action handler to perform some logic...
however when i replace with alv where i displayed one column with link to action cells using CL_SALV_WD_UIE_LINK_TO_ACTION class, however when i click on any particular cell i only get information related to that cell like column name, attribute name, value and position.
however as i said i need context element reference to work with which is not coming with alv.
please suggest.yes, that is right, you have to get the context element from the node based on the Index you get.

Setting Visibility to Table cell editor
Hi
I created a table and added a colomn to the table in view layout. Cell editor of that colomn contains an image. Based on some conditions , I need to make image invisible in table cell editor of custom colomn.
How can I do it.Example:
Context:
Rows (model node)
-- Name (attribute, string)
-- Additional (value node, card=1:1, selection=1:1, singleton=false)
---- EditorVisibility (attribute, type=Visibility)
Data binding:
LinkToAction.visible -> Rows.Additional.EditorVisibility
Make editor in row at index 4 visible if name is not empty:
IRowsElement row = wdContext.nodeRows().getRowsElementAt(4);
row.currentAdditionalElement().setEditorVisibility(row.getName() != null && row.getName().length() > 0
? WDVisibility.VISIBLE
: WDVisibility.NONE);
Ok?

Create a VC Model for BEx queries with Cell Editor
Hello All,
I am trying to create a VC Model for BEx queries with Cell Editor.
BW Development Team has created a BEX query with complex restrictions and calculations using Cell Editor feature of BI-BEX.
The query output in BEx analyzer is correct where all values are being calculated at each Cell level and being displayed.
But, while creating VC model, system is not displaying the Cells.Thus, no VC Model can be created.
I have executed below steps:
1. Created a VC Model for BEx Query - ZQRY_XYZ
2. Create Iview -> Create a dataService -> Provide a Table from the Output
In the Column field system is not showing any of the Cells (present in Cell Editor)
Please help me to solve this issue.
Thanks,
SivaHi
If 'Cell Editor' is been used then that query must have the structure in it. You have to select that 'structure' object in your 'VC Table'.
If you select that then you will get the required result in the output. This structure will be the structure where 'cell reference' is used in BI query, You have to select that structures name.

Dynamically change the cell editor in the table control
Hi..
I have 3 columns in a table . of which in one column we need to change the cell editor dynamically at runtime.
i.e for example i have columns as carrid, connid and fldate.
For the first 2 rows the cell editor for the carrid clomn shud be a dropdown and from there on in the next rows for the same carrid column it shud be a input field.
Can experts plz help me how to achieve this as this is very high priority issue....
Regards,
Madhu...This is actaully fairly simple to do. You will need to add a cellVariant to your table column. You can then dataBind a context attribute to the selectedCellVariant property of the column to control which cellVariant will be used. This allows you to control row-by-row which cell editor you want to output.

Also here is an example that I did the other day that uses Cell Variants within ALV. This process is actually a little more complicated because you have to go through the ALV APIs. To do this in a normal table is actually easier because you can create the cellVariant in the layout designer.

How to create a context menu in ALV table cell editor(Webdynpro abap )
Hello Experts,
I am having a problem in creating a context menu in a table cell editor in the ALV table output.I have assigned a 'lta' as the cell editor.But befor assigning the lta as cell editor I have assigned the menu to the lta.But when the view is rendered I can see the lta with the actioned assigned to it.But I cannot see the context menu.
The code snippet below:
"Create menu for each coloumn
create OBJECT lo_menu_actions type CL_SALV_WD_VE_MENU EXPORTING
id = 'MITM_ACTIONS'.
lo_menu_actions->set_visible( value = abap_true ).
lo_menu_actions->set_visible_fieldname( value = 'ACTIONS' ).
"ADd menu items

id = 'MITM_CREATE_EXPRESSION'.
lo_menu_item_create->set_visible( value = abap_true ).
lo_menu_item_create->set_visible_fieldname( value = 'Create' ).
"Add item 1
lo_menu_actions->ADD_ITEM( VALUE = lo_menu_item_create ).
" Set the cell editor for each column cell(link to an action)

lo_lta->set_menu( value = lo_menu_actions ).
lo_lta->set_text_fieldname( lv_column_name ).
lr_column->set_cell_editor( lo_lta ).
IF ls_node_dec_tab_cols-is_result EQ abap_true.
lr_column->set_cell_design( value =
cl_wd_table_column=>e_cell_design-key_medium ).
ENDIF.
ENDLOOP.Hi Prakash,
I have not come across this requirement till now to have context menu in a cell editor of alv.
Unfortunately the implementation of method SET_MENU of alv ui elements ( ex: cl_salv_wd_uie_text_view ) is not updating alv configurable table, instead it just stores in a global attribute as string. Hence has no effect on context menu.
If your user is very particular about this requirement of having context menu in cell editor, you can go for a normal table. Because, normal table's cell editor has the property to set the menuID as we do it for other ui elements.

Using a JPanel as cell editor in JTable
I have a composite component (JPanel that contains a JTextField and a
JButton) that I would like to use as the a cell editor in a JTable.The JButton instantiates a UI editor component that I have designed. Example would be date editor for dates, tet editor for strings etc. This editor allows the user to select a date to populate the JTextField (the date may also be manually entered).
I have no problem with the rendering of the component within the table.However, I would like for the JTextField embedded within the JPanel to receive focus and a visible caret, when using the tab key to navigate to the cell. After reading through some of the posts here , I was able to transfer the focus. But I dont see a visible caret. I am unable to edit. I have to click on the text box and then start typing. Its a great pain in the ass.
I have a custom designed table and custom designed editor. Code is attached...
<pre>
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,int condition, boolean pressed) {
final int selRow = getSelectedRow();
final int rowCount = getRowCount();
final int selCol = getSelectedColumn();
final EventObject obj = (EventObject) e;
if (selRow == -1) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
changeSelection(0, 1, false, false);
editCellAt(0, 1, obj);
boolean isSelected = false;
if ((ks == KeyStroke.getKeyStroke(KeyEvent.VK_TAB,0)) ||
(ks == KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0))) {
if (selCol == 1) {
isSelected= getCellEditor(selRow,selCol).stopCellEditing();
targetRow = (selRow + 1) % rowCount;
SwingUtilities.invokeLater(new Runnable() {

getComponentAt(targetRow, 1).requestFocus();
} else {
getCellEditor(selRow, selCol).shouldSelectCell(obj);
return super.processKeyBinding(ks,e,condition,pressed);
</pre>
Relevant code of my custom editor is below....

lastEditedRow = row;
lastEditedCol = column;
lastEditedTable = table;
lastEditedValue = value;

getCollection().cyclify();
button.setVisible(EditorForCollectionMap.hasUIEditor(collection));
button.setMargin (new Insets (1,1,1,1));
button.setIconTextGap(0);
buttonListener.model = (CycCollectionChooserModel)value;
buttonListener.rowIndex = row;
buttonListener.localTable = table;
return panel;
public boolean isCellEditable(EventObject evt) {
if (evt instanceof MouseEvent) {
int clickCount;
clickCount = 1;
return ((MouseEvent)evt).getClickCount() >= clickCount;
return super.isCellEditable(evt);
public boolean stopCellEditing() {

SwingUtilities.invokeLater(new Runnable() {
public void run() {
lastEditedTable.changeSelection(targetRow, 1, false, false);
lastEditedTable.getComponentAt(targetRow, 1).requestFocus();
return true;
return false;
Does any one know why I am not able to see the caret? Any insights you have will be most welcome.
Thanks in advance,

Formula Logic for Dates in the Cell Editor in Query Designer
Hi All
We are on BI7. (This is in the Cell Editor in Query Designer)
I am trying to create a formula in one cell that enters a date based on the following logic (Lets call this formula A):
I also have a placeholder "Cell reference" for a Date in another cell in the Cell Editor (Lets call it B).
I also have two other dates in seperate cells in the Editor (Lets call them C and D)
What i need to do is check that either C or D are not blank i.e one at least has a date and if so enter the date that is in B in A.
My formula logic in (Cell A) at the moment is as follows:
( Cell C <> 0 ) OR ( Cell D <> 0) * Cell B
When I run the query It is coming back with either a 1 or 0 depending if there is a date in C or D.
What I want it to do is to display the actual date of 'Cell B' in 'Cell A' if ( Cell C <> 0 ) OR ( Cell D <> 0)
If the value of B is blank ie no date I also want A to be blank i.e not equal zero or a blank date ie 00/00/0000
Example 1
Cell A 08/09/2009
Cell B 08/09/2009
Cell C 15/03/2010
Cell D
Cell A should = 08/09/2009 as there is a Date in Cell C or D and if so enter the date of Cell B in cell A
Example 2
Cell A
Cell B 08/09/2009
Cell C
Cell D
Cell A should = BLANK as there is a NO Date in Cell C or D
Example 3
Cell A
Cell B
Cell C 15/03/2010
Cell D
Cell A should = BLANK as there is a No Date in Cell B although a Date in cell C or D.
Thank you for assistance in advance
Kind regards
StevoHi there,
It seems you have done almost everything...
What it seems that is missing is probably the cell reference for Cell C and for Cell D, or did you forget to mention it here?
So here it is the big idea:
- In the Cell Editor of the query designer, create a new cell reference for Cell C, let's name it ref_cell_c;
- In the Cell Editor of the query designer, create a new cell reference for Cell D, let's name it ref_cell_d;
- In the Cell Editor of the query designer, create a new cell reference for Cell B, let's name it ref_cell_b;
- In the Cell Editor of the query designer, create a new formula for Cell A, let's name it form_cell_a;
The form_cell_a should be created by the following:
( COUNT(ref_cell_c) + COUNT(ref_cell_d) ) * ref_cell_b
So COUNT(operand) returns 1 if operand is different of 0 else it returns 0; So if ref_cell_c has any valu or ref_cell_d has any value it should return the value of ref_cell_b.
Please note that with this formula, if you have values in both ref_cell_c and ref_cell_d this formula returns 2 * ref_cell_b, which is not what you pretend, I'm assuming you'll have value only for the following combinations:
ref_cell_c has value but ref_cell_d don't have any
ref_cell_c don't have any value but ref_cell_d has a value
ref_cell_c don't have any value neighther has ref_cell_d any

Multi line issue in Table Cell Editor
Hi,
I am developing an occasionally connected application for handheld devices using NetWeaver Mobile 7.1. In one of the view, I have a table which display items information from the data source. In one of the column I need to display item description so I used TextEdit in the Cell Editor to display the information in multi line format and also wrapping is enabled.
But during testing of the application the TextEdit control does not wraps the text and as well as only first line of TextEdit control is visible inside the table and rest of the rows are not visible because of table's row height is not adjusted to the TextEdit control. I couldn't find any option to vary the size of the row height of the table.
Please suggest a solution to bring multi line display with in the table.
Also, check out my other issue posted here.
[Issue in wrapping of text in TextEdit control|Issue in wrapping of text in TextEdit control]
Thanks in advance.
Regards,
DVR.
Edited by: Vinodh Raj D on May 28, 2009 8:18 AMHi Vinodh,
Mutliline text in a text view/edit control inside a table cell is not supported.
You can view multiline text in a text view/edit as a seperate control inside a view. I think in case you want to see the whole address you can create a detail(s) view which can be navigated from the list (table) view.

How to display an image in particular cell editor
Hi All,
I want to display an image as the background for the table cell.
I searched in sdn and found the solution only for link to action.
I have created a dynamic table and if i click on apply button one more row is getting added according to my requirement.
I want to differentiate this row from rest. So I need to display image for the last row in the table which is added newly.
Can anyone suggest the procedure for adding an image in a particular cell editor along with the table data?
Hope I am clear with my requirement.
Pls suggest.
Regards,
subashiniHi,
IF iam not wrong then for some rows u need to show text data and for some rows u need to show image data.
follow the following steps.
1. In ur table add cell editor of type Image.
2.Create a value node with one more than required attributes.
3.Suppose if need to show only one column then i will create
value node with two attributes.One attribute will be for text
data and one will for Image.
4.now access ur table cell editor dynamically.For image type
cell editor we need to play only with two properties source
and alt.Bind this alt property of editor wid that attribute which u
need use for text data and source wid that attribute which u
need to use for image.
5. Now suppose I need to show text data then
I will create one element of that value node.In case of Image
type cell editor source property is given prefrence over alt
property.
set attribute which is bound to alt to the actual text data
i.e setText("Actual text data");
and set attribute which is bound to source to some dummy
image name
i.e setImage("dummy.gif");
add this to node.
during execution as source property of editor is bound to
Image attribute of node which in turn is set to dummy value it
wont find actual source and will set Image cell editor with
watever is bound to alt property which in turn set with actual
text value..
6. Now suppose I need to show Image data then
I will create one element of that value node.In case of Image
type cell editor source property is given prefrence over alt
property.
set attribute which is bound to alt to blank value
i.e setText("");
and set attribute which is bound to source to some Actual
image name
i.e setImage("Image.gif");
add this to node.
during execution as source property of editor is bound to
Image attribute of node which in turn is set to Actual image file
it will set Image cell editor with that image name and wont look for alt property.
Copy all ur images in src->mimes->components->ur package

List UIBB - Access to cell editor for a certain table line possible
Hi,
I am looking for a way to access the cell editor of the last table line as I want to mark it as a special - summary - line.
I intend a similar approach like in WebDynrpo ABAP when accessing the node info and modifying the "CELL DESIGN" attribute like in the following code (copied from WD Comp WDR_TEST_TABLE, View CELL DESIGN, method FILL_CELL_DESIGNS) :
data tab type IF_CELL_DESIGN=>Elements_Cell_Designs.
data line type IF_CELL_DESIGN=>Element_Cell_Designs.
data node_info type ref to if_wd_context_node_info.
data attribute_info type wdr_context_attribute_info.
data attr_value type WDR_CONTEXT_ATTR_VALUE.
node_info = node->get_node_info( ).
attribute_info = node_info->get_attribute( 'CELL_DESIGN' ).
line-is_expanded = abap_true.
line-is_leaf = abap_false.
line-key = 'FIRST'.
loop at attribute_info-value_set into attr_value.
line-text = sy-tabix.
concatenate 'Text #' line-text into line-text. "#EC NOTEXT
line-cell_design = attr_value-value.
insert line into table tab.
line-is_leaf = abap_true.
line-key = attr_value-value.
line-parent_key = 'FIRST'.
endloop.
node->bind_table( tab ).
I suspect the method IF_FPM_GUIBB_LISTGET_DATA (or IF_FPM_GUIBB_LISTGET_DEFINITION) of my feeder class to be the right access point.
But unfortunately, I have not yet found out how to change the cell design for specific lines, only for whole columns.
Can anyone give me a hint here?
BTW: The "summary" line is not a sum of the lines above, but determined by backend logic, so not ALV-summary line for me.
Kind RegardsHi,
A short update for all interested:
My current work around is to always set the lead selection to the summary line. It does in a kind "mark" that line as special as long as I cannot mark it using a different cell design.
How do I assure this?
I have implemented the following code in a redefinition of the method ADJUST_SELECTION:
*- alter selection
DATA:
ls_size TYPE rstabix.
"get index of summary line
ls_size-tabix = mo_collection->size( ).
"change only if there are any cash conc. proposals
IF ls_size-tabix > 0.
"do FPM selection
CLEAR: ev_lead_index, et_selection.
ev_lead_index = ls_size-tabix.
APPEND ls_size TO et_selection.
"do BOL selection
mo_collection->if_bol_bo_col_multi_sel~unmark_all( ).
mo_collection->if_bol_bo_col_multi_sel~mark( iv_index = ls_size-tabix ).
ENDIF.
The general downside is, that no other selection is possible!
The selection is always reset to the summary line with each roundtrip.
Waiting for a better solution...
Kind Regards,

Note: months will be changed based on user input(single Value)
how can use cell editor for above the senior.
if any option is availabel please let me know
Thanks
kishoreI think the following should work:
Context:
Rows (node,c=0:n)
--- rowIndex (integer)
selectedRowIndex (integer)
Bind the "selectedKey" property of the radio button (cell editor) to attribute "selectedRowIndex" (outside table data source node) and bind "keyToSelect" to attribute "Rows.rowIndex". Make sure that the "rowIndex" attribute will contain the index of the node element in node "Rows".

Small issue with custom table cell editor and unwanted table row selection
I'm using a custom table cell editor to display a JTree. Thing i notice is that when i select a value in the tree pop-up, the pop-up closes (as it should) but then every table row, from the editing row to the row behind the pop-up when i selected the value becomes highlighted. I'm thinking this is a focus issue, but it thought i took care of that. To clairfy, look at this: Before . Notice how the "Straightening" tree item is roughly above the "Stock Thickness" table row? When i select Straightening, this is what happens to my table: After .

}Any thoughts?

Edited by: MiseryMachine on Apr 3, 2008 1:27 PMAs I said, you have to have empty context elements before additional rows will be open for input.
For instance if you want to start with 5 rows available for input do the following to your internal table that you will bind:
data itab type standard table of sflight.
do 5 times.
append initial line to itab.
enddo.
context_node->bind_table( itab ).
The other option if you need n number of rows is to add a button to the table toolbar for adding more rows. When this button is pressed, you add a new context element to the node - thereby creating a new empty row in the table. -
Problem in JTable with a JComboBox cell editor
Hi gurus,
Please help! I am having a problem with a JTable that has a JComboBox cell editor. When the table is first loaded, the combo box column displays correct data. But whenever I click the combo box, the selection will be set to the first item in the combo box list once the popup menu pops up even before I make any new selection. It is very annoying.
Here is how I set the cell editor:
populateComboBoxModel(); // populate the combo box model.
DefaultCellEditor cell_editor = new DefaultCellEditor(new JComboBox(
combo_model));
contrib_table.getColumnModel().getColumn(1).setCellEditor(
cell_editor);
I didn't set the cell renderer so I assume it is using the default cell renderer.
Thanks !Not quite. The example doesn't have a different cell editor for each row of the table. I'm sure I must be missing something, bc I've found many references to the fact that this is possible to do. And I have most of it working. However, when I click on any given combobox, it automatically switches to the first value in the list, not the selected item. I've tried setting the selected item all over the code, but it has no effect on this behavior. Also, it only happens the first time I select a given cell. For example, suppose the first row has items A, B, and C, with B being the selected value. The table initially displays with B in this cell, but when I click on B, it switches to A when it brings up the list. If I select B, and move on to some other cell, and then go back and click on B again, it doesn't switch to A.
There seems to be a disconnect between the values that I display initially, and the values that I set as selected in the comboboxes. Either that, or it behaves as though I never set the selected item for the combobox at all.
Any help would be greatly appreciated. -
JComboBox as a cell editor in JTable
Hi,
I've set one of my columns in my table to have a JComboBox as a cell editor. This is fine but my problem is that each row has different values in the JComboBox but when I update each row the column with the JComboBox they all end up with the same values.
All help appreciated,
Thanks,
Lou
// column with JComboBox
TableColumn myCol = table.getColumnModel().getColumn(3);
Vector comboValues = new Vector();
JComboBox myCombo = null;
for (int row = 0; row < tableModel.getRowCount(); row++)
comboValues = new Vector();
if (row == 0)
// code here to add values to comboValues
myCombo = (JComboBox) (((DefaultCellEditor) (table.getCellEditor(row, 3, .getComponent());
myCombo = new JComboBox(comboValues);
myCol.setCellEditor(new DefaultCellEditor(myCombo);
tableModel.fireTableStructureChanged();
tableModel.fireTableDataChanged();
else
// get differnent values for comboValues and update comboValues Vector
myCombo = (JComboBox) (((DefaultCellEditor) (table.getCellEditor(row, 3, .getComponent());
myCombo = new JComboBox(comboValues);
myCol.setCellEditor(new DefaultCellEditor(myCombo);
tableModel.fireTableStructureChanged();
tableModel.fireTableDataChanged();Remember that you Table API specifies that each cell will use one instance of the specified editor...
Think about that... the same editor is being used for each cell in that column... therefore, setting the
data in the combobox et all will set it for that instance bveing used to edit the cell....
