Hello Anusha,

As WDP expert Amy said open the ST22 and then source code extract and find where you are getting actual dump. There can be no. of error and mostly error occurs due to improper layout assignment. So check all the layout assignment again.

you can use this document as reference for dynamic UI element creation.

Thank you very much Amy.Actually I was trying to create transaprent container with matrix layout and added this transparent container to root ui element(set grid data to this). Manually by creating layout its working fine.But when I am trying to create this through dynamic programming , It is gong to dump.I have checked in st22.It showing as

Dynamic type conflict when assigning references error.

Hi Chandra,

Thank you for giving reply.Yes , I have checked in st22 tcode its showing in some where internal method.Yeah its throwing error due to improper layout assignment.

[Former Member · Accepted solution]

look at your code " ROOTUIELEMENTCONTAINER" is type of grid layout. and the for TC1 you are trying to pass Matrix Head Data.

CALL METHOD CL_WD_MATRIX_HEAD_DATA=>NEW_MATRIX_HEAD_DATA
   EXPORTING
*    CELL_BACKGROUND_DESIGN = E_CELL_BACKGROUND_DESIGN-TRANSPARENT
*    CELL_DESIGN            = E_CELL_DESIGN-R_PAD
*    COL_SPAN               = '1'
*    DRAG_DATA              =
     ELEMENT                = lr_trans

Yes,I tried this by creating ui elements manually  in layout.Its working  fine i.e

ROOTUIELEMENTCONTAINER" is  of type grid layout. and  for theTC1 I pass Matrix Head Data.

But I am getting this error while creating dynamically.Can't we create like this?

[Former Member · Accepted solution]

How can we create something with Matrix head data into grid layout. ????

try to understand difference between Layout and Layout data..

[Former Member · Accepted solution]

You can create new TC with layout with matrix layout and into that you can provide head data and 1st element is by-default head data for Matrix layout.

Hi Shekhar,

I understood now, The issue is solved.Thanks a lot for quick and exact reply

okay, close this thread by marking ans as correct and helpful.

ok

Hi Anusha,

If you are seeing a short dump, you should take a look at the runtime error log in transaction ST22 to see what is causing the error. Your code appears to have more than one error, but the initial error you are seeing is a casting conflict between classes CL_WD_MATRIX_HEAD_DATA and CL_WD_GRID_DATA.

For this issue, the problem is that you have assigned the ROOTUIELEMENTCONTAINER a grid layout but you then try to add matrix layout data to it.

Instead of assigning the ROOTUIELEMENTCONTAINER a grid layout...

CALL METHOD cl_wd_grid_layout=>new_grid_layout
    EXPORTING
        col_count  = '1'
        container  = lr_container.

Assign it a matrix layout...

call method cl_wd_matrix_layout=>new_matrix_layout
    EXPORTING
        container  = lr_container.

This will resolve your initial error. ST22 will help you to identify the remaining errors.

You should also reconsider using hook method WDDOMODIFYVIEW for this code. Hook method WDDOMODIFYVIEW is executed every time the view is re-rendered. You should either check parameter FIRST_TIME to ensure you execute your code only once, or-- even better-- consider moving your code into hook method WDDOINIT which will execute only once when the view is initialized.

Cheers,

Amy

Hi Amy,

Thank you very much for giving reply.Can you please tell me cant we add transparent container with matrix data to a ROOT UI ELEMENT CONTAINER which is having grid data.Manually its working fine(By creating Layout).

i wrote that code in wddomodifyview method
