Hi,
I've seen that there are two ways to call a method (correct me if I'm wrong):
the first is by using CALL METHOD
the second is by using object->method( )
Whenever possible (ie. the parameters are only of Returning and Importing type) I prefer the second method a lot because it's more compact and Java-style.
Now I've faced the problem of getting the value of a context attribute.
Can you explain to me why this piece of code works:
DATA lo_nd_view_settings TYPE REF TO if_wd_context_node. DATA lo_el_view_settings TYPE REF TO if_wd_context_element. lo_nd_view_settings = wd_context->get_child_node( name = wd_this->wdctx_view_settings ). lo_el_view_settings = lo_nd_view_settings->get_element( ).
and this, instead, it doesn't work:
DATA lo_nd_view_settings TYPE REF TO if_wd_context_node. lo_nd_view_settings = wd_context->get_child_node( name = wd_this->wdctx_view_settings )->get_element( ).
I get this error:
Web Dynpro Comp. / Intf. ZPM_TEST_ABAP_WDP,Web Dynpro View MAIN 11 @0A\QError@
"= ..." expected after ")->GET_ELEMENT("
I mean, get_child_node returns an IF_WD_CONTEXT_NODE type object who has the method GET_ELEMENT.
So why it doesn't work?
Thank you,
Pietro
