    Sai,

    you should select boolean only for checkbox. so you can pass only boolean value for check box. Change the field to boolean on the backend.

      Hi Raj,

      As I said I have 19 rows in the backend(Ztable) where 4 rows values vill be "X", in the view(2 columns checkbox, text view) I could get all the 19 rows the textview is displayed well but the check box are all unchecked.

      when I select a particular row then the value is displayed as checked if it is "X" at backend and viceversa. i.e., the 4 rows values are displayed checked only when we select them.

      Regards ,

      Sai

    Add a (calculated, readOnly=false, boolean) attribute "Checked" to the context node.

    Assuming the char(1) attribute is named "X", implement the get and set methods like

    boolean getChecked(I<Node>Element element)
{
  return "x".equalsIgnoreCase( element.getX() );
}

void setChecked(I<Node>Element element, boolean value)
{
  element.setX(value ? "x" : " ");
}

      Hi Armin,

      I didn't get what you are saying, See my requirement is,

      1) I would get a table with 2 columns from bapi.

      2) 1st field is fname which is binded to textview.

      3) 2nd field is check(char 1) which should be a check box.

      4) I should display the table contents for editing, i.e., user should allowed to select the required "fname" with the corresponding "check" field checked.

      5) finally these updated values are to be stored back again.
