Hi,
Yes, apologies. There is nothing fancy about what I do, a simple table with data added to it.
It only happens when I click (select) a row, on the next update, this npe happens. I think it is outside my code.
A small snippet would be fairly hard to implement.....

Tableview getting refreshed when changing data in the rows

Hi Gurus,
Iu2019m doing a BSP with MVC. The requirement is as below.
In the main page there is a button u2018Create Orderu2019, to create a sales order, once I click this button, another screen (pop up) comes up and within that I have a Tableview display with the below fields with the data of 20 records.
Material no
Quantity
Delivery Date
Here user is allowed to choose the quantity and delivery date by selecting each row.(with MULTISELECT option in BSP)
The issue is after I select first row and change the quantity and date, and if I click on second row, the Tableview gets refreshed to enable the second row to be editable and the changes what I did on the first row are also refreshed.
So i want the Tableview not to be refreshed when selecting the multiple rows. So that I can keep the changes I make to the quantity and date fields Can you please suggest any method.
Cheers,
Srini.

Hi Srinivas,
You need to capture the value entered by user in Quantity and date field and update the internal table with these values for the current selected row.
For ex.
The tableView code is like:
 <htmlb:tableView id = "material"
 headerText = "<%= otr(Z_SUS/HEADER_TEXT_MATERIALS) %>"
 headerVisible = "true"
 design = "alternating"
 onRowSelection = "MyEventRowSelection"
 selectionMode = "MULTILINEEDIT"
 width = "880"
 filter = "SERVER"
 emptyTableText = "<%= otr(Z_SUS/EMPTYTABLE_MATERIALS) %>"
 iterator = "<%= iterator %>"
 table = "<%= gt_materials %>" />
In eventhandler OnInputProcessing :
DATA: lt_fields type tihttpnvp ,
 ls_fields like line of lt_fields.
call method request->get_form_fields
 changing
 fields = lt_fields
Now the internal table lt_fields contains all the editable cell values , just update the internal table of your tableview with these values.

o_event = cl_htmlb_manager=>get_event( request ).
 if o_event is not initial.
 if o_event->id = 'osha_update'.

Hi Guys,
Thanks for valuable suggestion. Let me give you over view of application. We have sub-controller
for all views, one controller and one model for those sub controllers and views.
Hi Sebastian,
Are you suggesting to use new model for all table view iterator ?
If i use iterator on that one model i can't use
that for other table view iterator..right ?
Hi raju,
If i get all the values on 'do_handle_data' method in the controller class, can i use that
for other table view iterator if i create a new table view iterator? can i have some
outline(example coding) of passing those values to sub controller ?
Thanks in advance.

Updation of internal table from tableview

Hi,
I am using a tableview in which coloumn-3(last_days) is editable.After editing it when user pressess on the button SAVE I should capture the changes and update it in database.
But here I am facing a problem.Always the field last_days is being filled with '000' irrespective of the value entered.
The below is the piece of code which I had written:
DATA: tv TYPE REF TO CL_HTMLB_TABLEVIEW,
wa like line of R_GT_VIEW.
tv ?= CL_HTMLB_MANAGER=>GET_DATA(
request = runtime->server->request
name = 'tableView'
id = 'tvx' ).
IF tv IS NOT INITIAL.
DATA: tv_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
tv_data = tv->data.
loop at R_GT_VIEW into wa .
wa-last_days = tv_data->get_cell_value( row_index = sy-tabix
 column_index = '3' ).
modify R_GT_VIEW from wa index sy-tabix.
endloop.
ENDIF.
Helpful answers will be rewarded.
Thanks

Hi,
Sorry....coz I replied in a haste...
Just to let you know....The method get_cell_value will not work if you are rendering a column as InputField.
Use the below mentioned code and this it should work....
DATA: tv TYPE REF TO cl_htmlb_tableview.
 wa like line of R_GT_VIEW.
tv ?= cl_htmlb_manager=>get_data(
 request = runtime->server->request
 name = 'tableView'
 id = 'tvx' ).
IF tv IS NOT INITIAL.
DATA: tv_data TYPE REF TO cl_htmlb_event_tableview.
tv_data = tv->data.
LOOP AT itab INTO wa .
 data : if_value type ref to cl_htmlb_inputfield.
 data : p_cell_id type string,
 row_ix type string.
 clear p_cell_id.
 clear row_ix.
 row_ix = sy-tabix.
 condense row_ix.
 concatenate p_cell_id 'TV_' row_ix '_3' into p_cell_id. "generating cell ID...Make Sure to use ur TableView Id instead of TV
 if_value ?= cl_htmlb_manager=>get_data( request = request
 name = 'inputField'
 id = p_cell_id
 if if_value->value is not initial.
 wa-last_days = if_value->value.
 endif.
 MODIFY itab FROM wa INDEX sy-tabix.
ENDLOOP.
Do reward each useful answer..!

"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.

How to get editable value from thtmlb:tableView

Hi,
I create a tableview using tag thtmlb:tableView and set column editable. Now the value in the tableview can be changed, but I don't know how to get the changed value from tableview. Pls help me.
thanks in advance!

Hi,
You can get the collection of the context node and any line of the table is an entity in the context node.
If it is not helpfull try to find a table called 'table' or 'tableview', maye it's an attribute in your context node.

Retrieving table values from tableview multiselect

Hi everyone,
I have a BSP with a tableView set on multiselect. When the user clicks on a button I want to rertieve the selected rows in my ABAP code and send them to a function module (in the form of a table). But I haven't been able to find code examples on how to do this, ie how to retrieve the selected rows. Can someone provide me with an example or a link to where I can find one? I can catch the button onClick event, but after that I need to get the rows that were selected by the user.
Thanks!
best regards,
Dionisios

HI Dionisios,
In your input processing,
do something like
CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
IF event_id = CL_HTMLB_MANAGER=>EVENT_ID.
DATA: event TYPE REF TO CL_HTMLB_EVENT.
event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
if event->id = 'but1' and event->event_type = 'click'.
DATA: tv TYPE REF TO CL_HTMLB_TABLEVIEW.
tv ?= CL_HTMLB_MANAGER=>GET_DATA(
 request = runtime->server->request
 name = 'tableView'
 id = 'tab1' ).
IF tv IS NOT INITIAL.
DATA: tv_data TYPE REF TO CL_HTMLB_EVENT_TABLEVIEW.
tv_data = tv->data.
refresh itab2.
refresh itab3.
call method tv_data->GET_ROWS_SELECTED
 receiving selected_rows = itab2.
endif.
data : ind type SELECTEDROW,
 row_s type row.
if itab2 is not initial.
 data :rw LIKE LINE OF itab.
 loop at itab2 into ind.
 READ TABLE itab INDEX ind-index into
 rw.
 if rw is not initial.
 row_s = rw.
 append row_s to itab3.
 clear row_s.
 endif.
 endloop.
endif.
Endif.
Where
TYPES
types : tab type table of <table_name>.
types : row type <table_name>.
PAGE ATTRIBUTEs :
Irow type row
Itab type tab.
Itab3 type tab.
Itab2 type selectedrows.
Rowselected type string.
And in layout
<htmlb:tableView id="tab1"
 table="<%= itab %>"
="true" >
 visibleRowCount="8"
 design="ALTERNATING"
 footerVisible="TRUE"
 selectionMode="multiSelect"
 keepSelectedRow
 </htmlb:tableView>
<htmlb:button id = "but1"
 onClick="test"/>
HOpe this helps,

Getting filtered values from TableView

Hi,
We have a TableView whose columns can be sorted. Iwant to select a few rows and make the selected rows editable in another page.
If it is a unsorted/unfiltered TableView, am able to do it as the ABAP Internal Table and the TableView are the same in terms of record index positions. But am facing problem after i sort/filter the TableView because now the index of the TableView are different from the index of the ABAP Internal Table present in server.
Anybody who has dealt with this problem earlier and can guide us.
Thanks,

How to change the default KeyBinding of the TableView ?

how to change the default key binding of the TableView ?
When press Enter key on a editable TableView, the default action is to make the selceted cell to a editing state. I want to know if there is any way to make it select the right cell and wouldn't change the editing state of the selected cell when i press Enter key.
here is something i've done.
 table.setOnKeyPressed(new EventHandler<KeyEvent>() {
 @Override
 public void handle(KeyEvent e) {;
 table.requestFocus();
 KeyCode code =e.getCode();
 if(code == KeyCode.ENTER){
 try {
 new Robot().keyPress(java.awt.event.KeyEvent.VK_RIGHT);//XXX
 } catch (Exception e1) {
Thanks,
ahiwoo

thanks jsmith. now it works well.
 table.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {
 @Override
 public void handle(KeyEvent e) {
 table.requestFocus();
 KeyCode code =e.getCode();
 if(code == KeyCode.ENTER){
 try {
 new Robot().keyPress(key);//XXX javafx has no robot for key type...
 } catch (Exception e1) {
 e.consume();
 });

Problem with iterator in tableview

Hi, Im having a problem with an iterator in a tableview. Sometime ago I use an iterator in a BSP with flow logic, I created the class fill the methods GET_COLUMN_DEFINITIONS and RENDER_CELL_START. And worked fine.
Now, Im working in another BSP and this time I wanted to use MVC, so I have been reading but cant figure it out what Im missing out.
In the controller of my page I add the Interface IF_HTMLB_TABLEVIEW_ITERATOR
I ridefine the methods GET_COLUMN_DEFINITIONS and RENDER_CELL_START (I think that you dont have to redifine GET_COLUMN_DEFINITIONS but did it anyway just in case).
This is my RENDER_CELL_START
IF NOT ( p_column_key = 'ICON' ).
 RETURN.
ENDIF.
FIELD-SYMBOLS: <row> TYPE ANY, <col> TYPE ANY.
DATA: ti_results TYPE ZBSPREP_VEND_T,
 wa_results TYPE ZBSPREP_VEND.
ASSIGN p_row_data_ref->* TO <row>.
ASSIGN COMPONENT p_column_key OF STRUCTURE <row> TO <col>.
wa_results = <col>.
DATA: html_bee TYPE REF TO CL_BSP_BEE_HTML.
CREATE OBJECT html_bee.
LOOP AT it_results INTO wa_results.
 icon = CL_BSP_MIMES=>SAP_ICON( id = 'ICON_GREEN_LIGHT' ).
ENDLOOP.
p_replacement_bee = CL_HTMLB_IMAGE=>FACTORY( id = p_cell_id src = icon ).
In my table view the column ICON doesnt show anything and the rare part is if I put breakpoint in the method and execute the page doesnt stop.
So I dont know if Im missing something.
My tableview layout is this:
<htmlb:tableView id = "Monitor"
 selectionMode = "SINGLESELECT"
 onRowSelection = "rowSelection"
 table = "<%= it_results %>"
 iterator = "<%= iterator %>"
 design = "ALTERNATING"
 filter = "SERVER"
 sort = "SERVER"
 headerVisible = "FALSE"
 footerVisible = "FALSE">
I declare a attribute iterator TYPE IF_HTMLB_TABLEVIEW_ITERATOR.
Someone could give a hand ?

Solved, I forget to set the attribute of the view in the REQUEST Method.
result_view->set_attribute( name = 'iterator' value = me ).

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.

I think you problem lies in this part.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath {
 const NSDictionary *const row = [self rowForIndexPath:indexPath];
 NSString *wantedClassName = [row objectForKey:@"controller"];
 UIViewController *const vc = [[NSClassFromString (wantedClassName) alloc] init];
 NSLog(@"controller is -%@-", wantedClassName);
 [self.navigationController pushViewController:vc animated:YES];
 TableViewPushAppDelegate *appDelegate = ( TableViewPushAppDelegate *)[[UIApplication sharedApplication]delegate];
 appDelegate.myImage = [[NSString alloc]initWithFormat:@"%@",[[tableDataSmobjectAtIndex:indexPath.row]objectForKey:@"picture"]];
NSLog(@"%@", appDelegate.myImage);
appDelegate.textView = [[NSString alloc]initWithFormat:@"%@",[[tableDataSm objectAtIndex:indexPath.row]objectForKey:@"description"]];
 [vc release];
specifically the underlined part. does this need modifying or completely rewritten.

Image Column in Tableview

Hi all,
here's the thing: I'm trying to add an image column to a tableview but it doesn't work (there's no error, but the image doesn't appear). I've tried it with an iterator.
Page Layout:
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design = "design2003"
 controlRendering = "SAP" >
<htmlb:document>
 <htmlb:documentHead>
 </htmlb:documentHead>
 <htmlb:documentBody>
 <htmlb:form>
 <htmlb:tableView id = "tableview_scarr"
 table = "<%= pa_tab_scarr %>"
 headerText = "Table SCARR"
 headerVisible = "TRUE"
 iterator = "<%= application %>" >
 </htmlb:tableView>
 <%
IF page->messages->num_messages( ) > 0.
 %>
 Error
 <%
ENDIF.
 %>
 </htmlb:form>
 </htmlb:documentBody>
</htmlb:document>
</htmlb:content>
OnInitialization:
SELECT * FROM scarr INTO TABLE pa_tab_scarr.
My application class is my iterator. It implements GET_COLUMN_DEFINITIONS:
METHOD if_htmlb_tableview_iterator~get_column_definitions.
DATA tv_column TYPE tableviewcontrol.
tv_column-columnname = 'SHOW_ICON'.
tv_column-title = 'SHOW_ICON'.
tv_column-encode = 'X'.
tv_column-width = '100'.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-columnname = 'CARRID'.
tv_column-width = '100'.
APPEND tv_column TO p_column_definitions.
ENDMETHOD.
...and it implements RENDER_CELL_START:
METHOD if_htmlb_tableview_iterator~render_cell_start.
CASE p_column_key.
 WHEN 'SHOW_ICON'.
 DATA col_image TYPE REF TO cl_htmlb_image.
 CREATE OBJECT col_image.
 col_image->src = "@2N@".
 col_image->width = '16'.
 col_image->height = '14'.
 p_replacement_bee = col_image.
ENDCASE.
ENDMETHOD.
I've checked the SICF, but all services concerning icons are activated. This is my first Iterator so i'm not sure if i've forgotten something. Why the image is not shown?
Regards
Mark-André

Hi Mark,
First of all, define an object named iterator in page attributes type ref to iterator_class_name
i.e
iterator TYPE REF TO ZCL_ITERATOR(or iterator_class_name)
Then in onInitialization use
create object iterator.
Also you can use any name of the iterator object...but the name application is reserved for the application class....
So your tableView code will be
 <htmlb:tableView id = "tableview_scarr"
 table = "<%= pa_tab_scarr %>"
 headerText = "Table SCARR"
 headerVisible = "TRUE"
 iterator = "<%= iterator %>" >
Rest all is fine...!!
Hope this helps.
Do reward each useful answer..!
Thanks,
Tatvagna.
