Search help that populates two fields on a WEB dynpro page

Question

Hi there,
I have created a search help based on a single table ( QPCD ) with two exporting parameters CODEGRUPPE and CODE. When the user selects a their desired entry i would like it to poulate the relevant two fields on the web dynpro screen. I know in a normal dialog screen you could get this to happen automatically, but when implementing it into a web dynpro from abap screen it only returns the first value into the field that the search help was called from. Anyone know how i could get both fields populated?
Thanks in advance
Regards
Mart

It is not that hard.
Create a new webdynpro component and implement IWD_VALUE_HELP in this component.
go to the component controller of you new component and add a new attribute:
listener type ref to IF_WD_VALUE_HELP_LISTENER.
in the method set_value_help_listener add the line:
wd_this->listener = listener.
then you can create as much views and things you need for your search help.
To set a selected value just add a method to your component controller which takes the values as import parameters. if you only want to set the value for the attribute it was requested for:
  wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = wd_this->listener->F4_ATTRIBUTE_INFO-name
    value = <value>
This is the save way
But you can also call
  wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = 'CODEGRUPPE'
    value = <value_codegruppe>
  wd_this->listener->F4_CONTEXT_ELEMENT->set_attribute(
    name = 'CODE'
    value = <value_code>
But keep in mind that if the structure of the element changes, this could lead to short dump if the name of the attribute changes or the attribute was deleted.
if you want to close the search help window call wd_this->listener->close( ).
Hope this helps.
