Hi,

I am trying to set the property of a text item in my form to false using SET_ITEM_PROPERTY.

My code goes something like this:

SET_ITEM_PROPERTY('TEXT1',ENABLED,PROPERTY_FALSE);
SET_ITEM_PROPERTY('TEXT1',NAVIGABLE,PROPERTY_FALSE);

But when this code executes my application gets stuck(hangs) and the mouse cursor changes to the hour glass.There is no other option but to end the session and relogin.

The problem is not encountered if I change the code to :

SET_ITEM_PROPERTY('TEXT1',INSERT_ALLOWED,PROPERTY_FALSE);
SET_ITEM_PROPERTY('TEXT1',UPDATE_ALLOWED,PROPERTY_FALSE);
SET_ITEM_PROPERTY('TEXT1',NAVIGABLE,PROPERTY_FALSE);

I am clueless about such behaviour.Can anyone help me out??

Thanks in advance.

What happens if you remove the "navigable" part? When the item is DISABLED, it is not navigable anyway.

Check out the following link:
http://www.oracle.com/webapps/online-help/forms/10g/state/content/navId.3/navSetId._/vtTopicFile.f1_help|propsd_f|enabled~html/

It clearly explains that "When Enabled property is No, an item is always non-Keyboard Navigable. At runtime, when the Enabled property is set to PROPERTY_FALSE, the Keyboard_Navigable property is also set to PROPERTY_FALSE".

I think you should be good if you just set the ENABLED property to FALSE as mentioned by Littlefoot.

Initially the code was just

SET_ITEM_PROPERTY('TEXT1',ENABLED,PROPERTY_FALSE);

During runtime when this code executed,it tried setting some of the other properties as false.This I guess was the reason for the application to get stuck.I felt that by explicitly setting the other properties (viz NAVIGABLE,REQUIRED,UPDATEABLE etc) to false would resolve my problem.Therefore I introduced code for making NAVIGABLE property to false.Even I tried various other combinations with the ENABLED property.But that didn't help.

One thing I would like to mention is that it happens only in forms 10g whereas in forms 6i this code simply works fine.I was wondering if its some problem with forms 10g version.

Hi David,
When I set Enabled to No, it grays out the item. But I want the item to appear normally. So, I tried to put mouse_navigate, navigable, update_null and update_allowed property to false. But still user able to click on the List item.. But they can not change the value. Is it possible to enable the item without changing the color.
Thanks in Advance,
Sundar

You ask: "Is it possible to enable the item without changing the color." Do you mean 'disable'? If so, then no.

In the 'show_lov' trigger test whether the item has 'update allowed' and if not, then just do a 'bell' and 'raise form_trigger_failure'.
