Table not ready for input

hello folks,

i got a table in a view, whereas its readonly-attrbute is bound to a context attribute named X_READ_ONLY (type WDY_BOOLEAN). on the first call of the view X_READ_ONLY is initial, which means, that the table appears as input ready. unfortunately, the table only appears to be ready for input, which means, that the background color of the cells is white, but i can not change any value of any cell.

as soon as X_READ_ONLY becomes 'X', the background color of all cells turns grey, indicating that the table is not ready for input any more.

what can be the reason, for the table not becoming truely input ready?

the table is bound to a table-attribute of a class object reference, whereas this attribute is NOT marked to be read-only!!!

thx

mike
