Picklist in Advanced Search View

Question

Hi everybody,
I've got a problem using dropdown list in an advanced search view in the WEB CLIENT UI CRM 7.0 in a Z component , here's the thing:
I have 5 search criteria, and I need to make them dependent from each other, I mean, if the first field has a value (e.g. CAR), the next field has to show just the data associated to it (e.g. data associated to CAR).
The problem is, when a value is picked from the dropdown list, it doesn't trigger any events in order to catch the value of the first field, so I have not found the way to solve this.
Has anybody come across with this problem before?,
Did you solve it?,
Do you have any ideas for this?
Thanks in advance¡

Hi DLemuS,
The following solution might help. For the purpose of explaining, I would use two field FLD1 and FLD2. Values available in drop-down for FLD2 should be dependent on value selected in FLD1.
1. In your search component, context node, generate the getter-setter methods for FLD1.
                     1.1 In the GET_V_FLD1 method, write code to populate the drop-down values for FLD1.
     1.2 In the GET_P_FLD1 method, check for the parameter iv_parameter. if iv_parameter = 'ServerEvent' then set the return value rv_value = 'DUMMY'.
2. In your component controller
     2.1 Declare a public global table (say GT_DDLB) of type bsp_wd_dropdown_table
     2.2 Redefine do_handle_event method. call the super class and then check if the event = 'DUMMY' then get the value in FLD1 using by calling the get method and populate the values for the second field into the global table gt_ddlb correspondingly
3. In your search component, context node, generate the getter-setter methods for FLD2. In the GET_V_FLD2 method, declare a variable (gr_ddlb) of type reference to CL_CRM_UIU_DDLB. Call the method gr_ddlb->set_selection_table( it_selection_table = gt_ddlb ).
If this does not work, then in 2.2 above, try to populate the list of values for FLD2 direcltly.
Hope this helps!
