Blank row in table UI Element

Question

Hi All,
I am having a UI table element in my screen. Below that i ve some input fields. When i lead select a row in table, the input field data changes accordingly.
When i do not have a row in the table, am getting an error message saying no value for the input field.
So when there is no row in table, if i append a blank row. It is working fine. Can anyone give someother solution for this issue.??
Because in this solution we have a blank row in table when the table is empty. We do not want this blank row
Am binding the table and the input fields below to the same node. (So that the table row data automatically reflects in the input fields below).

hii ,
u shud try using this :
1 create a context attribute , say attr1 ,of type string under a separate node of cardinality 1..1 or 1..n ,say context node is cn_all.
2 bind this attribute  attr1 with the value property of the ur UI element INput Field's .
3 set the value of ur attribute of attr1 in ONLEAD SELECT of the  TABLE .
  DATA lo_nd_cn_all TYPE REF TO if_wd_context_node.
    DATA lo_el_cn_all TYPE REF TO if_wd_context_element.
    DATA ls_cn_all TYPE wd_this->element_cn_all.
    DATA lv_attr1 LIKE ls_cn_all-attr1.
*   navigate from <CONTEXT> to <CN_ALL> via lead selection
    lo_nd_cn_all = wd_context->get_child_node( name = wd_this->wdctx_cn_all ).
*   get element via lead selection
    lo_el_cn_all = lo_nd_cn_all->get_element(  ).
*   set single attribute
    lo_el_cn_all->set_attribute(
      EXPORTING
        name =  `ATTR1`
      IMPORTING
        value = lv_attr1).
in this way , u wud not be creating the empty rows , also wud not get runtime error for ur Input field
