TableView: ITERATOR in MVC
Using the MVC design pattern, ITERATOR methods (e.g. IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START) can be implemented in the Controller, in the Model or in a seprated class.
I give my vote to the CONTROLLER...
And you, which is the best place where to implement it?
Sergio
Hi Sergio,
it depends on what exactly you want to do in your methods.
For pure tableview rendering problems I would recommend leaving it in the iterator.
I try to keep my application's methods well structured and always in the class they do belong most to - thinking about placing iterator methods somewhere else is something I have not thought of before, and I don't think I will do so anytime ...
Using the controller as you suggested ... not so appropriate imo, as a controller was introduced to separate display and application code, and the iterator is used to change display/rendering of a tableview.

Problem with tableview iterator
Dear friends.
I try to adopt tableview iterator in my customer's BSP pages. So, I programmed test page.
METHOD if_htmlb_tableview_iterator~render_row_start .
m_row_ref ?= p_row_data_ref.
ENDMETHOD.
M_ROW_REF is "Static Attribute" and "Public" and "Type Ref To Z3TYDISP"
z3tydisp has structure as below
REQNO NUMC 12
VGUBUN CHAR 1
DSCOFVGUBUN STRING 0
REQDT DATS 8
RNAME CHAR 10
VCOMP CHAR 30
VNAME CHAR 10
VPLACE CHAR 5
VPLACEDSC CHAR 20
APPROVAL CHAR 1
DSCOFAPPROVAL STRING 0
AND... p_row_data_ref has structure below
REQNO N 12
VGUBUN C 1
DSCOFVGUBUN g 0
REQDT D 8
RNAME C 10
VCOMP C 30
VNAME C 10
VPLACE C 5
VPLACEDSC C 20
APPROVAL C 1
DSCOFAPPROVAL g 0
In my option, p_row_data_ref has same structure compared with z3tydisp. But there is "CX_SY_MOVE_CAST_ERROR". How I have to define "z3tydisp"????>><b>M_ROW_REF is "Static Attribute" and "Public" and "Type Ref To Z3TYDISP"</b>
instead of this make your M_ROW_REF a instantaneous attribute. since static attribute are intantiated only once when object created and are shared by all other intances. m_row_ref contains data about the table you are going to render using tableview. so it should be public, so that get different data for different iterator objects.
your p_row_data_ref must be of type ref to data which is superior class of data types.
and if you have defined iterator "IF_HTMLB_TABLEVIEW_ITERATOR" in your interfaces. then you need not to define structure for p_row_data_ref, its already there in interface.
hope this will solve your problem,

TableView Iterator in WebDynpro as in BSP
Hi all,
i'm planning to move from BSP to WebDynpro ABAP and have a question:
Does WD ABAP provide the same kind of <htmlb:tableView> as BSP? Especially, does it support the concept of an tableview iterator?
Thx & Regards,
DanielYes you'll find everything.
You'll find also the ALV extension of a table.
I was familiar with iterator and I like it so much; in WDA you can reach the same result but in a different way.
Basically you have to prepare, in advance, all the data in the table rows and then in the table configuration you'll describe the rules for each column (even with variants per row).
You have to study the Table UI object with table cell variant and then ALV features.

Nested image Tag in tableview iterator
In the past I use the tableview tag "tableViewColumn". In this tag a nested image tag inside a link tag was used.
Now I use the tableview iterator. But I can only define one p_replacement_bee in the RENDER_CELL_START method.
Does anyone knows a solution for my problem?
Example:
<htmlb:tableViewColumn columnName = "transport"
tooltipColumnKey = "transport_tooltip"
type = "user"
title = "<%= otr(zinternet/tracking) %>"
horizontalAlignment = "center" >
<htmlb:link id = "$TVCID$"
reference = "$TRANSPORT_LINK$"
target = "_blank" >
<htmlb:image src="$TVCVALUE$" />
</htmlb:link>
</htmlb:tableViewColumn>Just off hand I see one problem. In your reference you have 'www.sap.com'. This link wouldn't work (and might be causing your problem, because without the http:// on the front it would assume that was a relative path.
Other than that I don't see a problem off hand. I normally don't render my elements to BEEs and then add the BEEs to the BEE Tree. I prefer to render to elements and then use the ADD method instead of the ADD_BEE method:
data: tag_gl type ref to cl_htmlb_gridlayout,
tag_glc_if1 type ref to cl_htmlb_gridlayoutcell,
tag_glc_if2 type ref to cl_htmlb_gridlayoutcell,
tag_glc_if3 type ref to cl_htmlb_gridlayoutcell.
tag_gl = cl_htmlb_gridlayout=>factory(
columnsize = '3' rowsize = '1' ).
tag_glc_if1 = cl_htmlb_gridlayoutcell=>factory(
columnindex = '1' rowindex = '1' ).
tag_glc_if2 = cl_htmlb_gridlayoutcell=>factory(
columnindex = '2' rowindex = '1' ).
tag_glc_if3 = cl_htmlb_gridlayoutcell=>factory(
columnindex = '3' rowindex = '1' ).
data: seats_bee type ref to cl_bsp_bee_table.
create object seats_bee.
seats_bee->add( level = 1 element = tag_gl ).
seats_bee->add( level = 2 element = tag_glc_if1 ).
seats_bee->add( level = 3 element = if_first ).
seats_bee->add( level = 2 element = tag_glc_if2 ).
seats_bee->add( level = 3 element = if_bus ).
seats_bee->add( level = 2 element = tag_glc_if3 ).
seats_bee->add( level = 3 element = if_econ ).
p_replacement_bee = seats_bee. -
Hi,
I have created a composite BSP element that outputs a matrix with two cells, the first containing an icon, the second with a description. This works fine when placed in a BSP page.

Message was edited by: P24101990Hi Mark,
Thanks for your reply. I tried that in DO_INIT and in DO_REQUEST as well. I started of this application well with the values selecting from Dropdown and then rendering the table columns. But now I have commented everything and just trying to render one column of the table....
I have one concern.
I have declared like this
tv_iterator type ref to ZITERATOR.
and in DO_INIT I have instantiated. Create Object tv_iterator.
If you have any suggestions please let me know....

Composite Element in Tableview Iterator
I want to use a <phtmlb:matrix> element in a tableview iterator to arrange the content of a cell.
I tried to follow Brians Weblog on composite elements.
In my test example, I just want to combine two fields of t000 into one cell. Of course I know, that concatenation would be more easy here, but that would not answer my questions.
Thought it could look like this:
METHOD render_cell_start.
DATA:
l_o_matrix TYPE REF TO cl_phtmlb_matrix,
l_o_bsp_element TYPE REF TO cl_bsp_element,
l_string TYPE STRING.
CASE p_tableview_id.
WHEN 'TABLE_T000'.
l_o_matrix = cl_phtmlb_matrix=>factory( ).
WHILE o_page_context->element_process( element = l_o_matrix )
= cl_bsp_element=>co_element_continue.
Cell 1
CLEAR: l_o_matrix->mc_backgrounddesign,
l_o_matrix->mc_design,
l_o_matrix->mc_separation.
l_o_matrix->do_set_data( element_name = 'matrixCell' ).
l_string = me->t000-mandt.
l_o_bsp_element = cl_htmlb_textview=>factory( text = l_string ).
WHILE o_page_context->element_process( element = l_o_bsp_element )
= cl_bsp_element=>co_element_continue.
ENDWHILE.
Cell 2
CLEAR: l_o_matrix->mc_backgrounddesign,
l_o_matrix->mc_design,
l_o_matrix->mc_separation.
l_o_matrix->mc_halign = 'LEFT'.
l_o_matrix->mc_valign = 'TOP'.
l_o_matrix->do_set_data( element_name = 'matrixCell' ).
l_string = me->t000-mtext.
l_o_bsp_element = cl_htmlb_textview=>factory( text = l_string ).
WHILE o_page_context->element_process( element = l_o_bsp_element )
= cl_bsp_element=>co_element_continue.
ENDWHILE.
ENDWHILE.
p_replacement_bee = l_o_matrix.
ENDCASE.
ENDMETHOD.
However, that does not work.
First, the list of T000-MANDT fields is rendered twice:
into the tableview and into a list before the tableview.
Second: T000-MTEXT does not show up at all.
What do I do wrong?
I feel that I do not completely understand how the rendering is processed.
Thanks for our help.
JuergenThe following is the example from Brian's weblog, updated for design2003. It doesn't use the Matrix however. Perhaps it will help.
It still doesn't render quite like it did under design2002. I'm not sure if there is a good way to combine multiple input fields into one cell any longer. I know others have had a problem with this as well. I will have to look closer at your matrix attempt.

Hello,
I try the weblog OF Brian McKellar corresponding to the HTMLB TableView Iterator and as like certain people, the Dropdownlist of the column 'CURRENCY' is empty. This is cetainely due of how in the constructor the table is declared. So, for those which succeeded in replir the Dropdownlist of the column 'CURRENCY' can they give me the code of your constructor.
Thanks a lot.
Farid BERRAHello Ariel,
Thanks to your councils, i succeeded to get data in the DROPDOWNLISTBOX.

I am currently working with BSP tableview iterator.
I have use many internal tables and the data are store in my class.
My question is how can i use certain data which already store in my class and display them in my tableview with iterator.
I use another internal table in my tableview, but when i try to refer my other data which already stored in my class, the internal table is empty.
Please guide and advise.
Thanks and regards,

You can use HTMLB Link in your RENDER_CELL_START method.
WHEN 'LINK'.
p_replacement_bee = cl_htmlb_link=>factory( id = p_cell_id
reference= 'http://www.yahoo.com/'
text = 'YAHOO'
target = '_new' ).
Hope this helps,
