[Former Member]

Hi @all,i am ettting the error in two statements upon compiling the following code

Formal parameter "INPUT_PROMPT" does not exist. .

&

   image_source = '~Icon/Search'

these two lines,the whole code is written as below

what i am doing exactly here is trying to create UI Elements Dynamically

and instead trying to change their properties using wizard i m applying thru code

motive is to embed

an input field in the tray with label attached to that input field and a button at bottom

pls. help in this regard,

Thanks in advance

          check for alternative parameter for input promt like BOUND_INPUT_PROMPT in the class cl_wd_input_field=>new_input_field and similarly for image source in the class  cl_wd_button=>new_button ..... this should resolve your issue............even if you take this parameter out it can work.

             check the following link for buttons

http://saptechnical.com/Tutorials/WebDynproABAP/UIHierarchy/dynamic.htm     and

           the following link for input fields........

http://webdynproabap.wordpress.com/2012/10/04/dynamic_uielemen/....

        Hope this helps...................

Hi Manu,

         if you open the class  cl_wd_button=>new_button and cl_wd_input_field=>new_input_field and check the parameter list for both the class method  you will not find the input_prompt and image_source parameter. Thats the reason its throwing the error.
