Oracle Forms

Dear all,

I've the following code in when button pressed trigger.

Set_Block_Property('SRC_BLOCK',INSERT_ALLOWED,PROPERTY_FALSE);

 Set_Block_Property('SRC_BLOCK',UPDATE_ALLOWED,PROPERTY_FALSE);

after this all items in this block can't be updatable ,except one item.

It still allow to update it's value(country_name). I don't know why ..

This item is attached with LOV.
when mouse double click trigger having code " list_values".

Please help me do figured out the problem..


But If i try with following code it's working..

set_item_property('SRC_BLOCK.country_name',enabled,property_false);

but the following code is not working..Why update and insert property is not working on this item..

set_item_property('SRC_BLOCK.country_name',update_allowed,property_false);

set_item_property('SRC_BLOCK.country_name',insert_allowed,property_false);

thanks in advance,
