Question

How can I Page Up to a previous block?

Asked by: geeta_m9

I have a form with three blocks. A key block, and two data blocks. My problem is sometimes when I try to page up to a previous block, I obtain the error, "No navigable items in destination block" and I am unable to page up. What is causing this error and how can I fix it?

I think that you use Oracle Forms. In block there must be at least 1 item with property Enabled = yes.
You can set items property before you use "page up".

 

by: geeta_m9Posted on 2009-10-12 at 08:46:47ID: 25552220

There are already items in the block with enabled property equals yes, so I don't understand why I am still getting that error.

Are you sure that the property is not changed programmatically ? Simply test it before going to the block.

This is from the on-line help (SET_ITEM_PROPERTY built-in):
Propagation of Property Changes
 You can only specify a change to one item property at a time through the SET_ITEM_PROPERTY Built-in. However, one SET_ITEM_PROPERTY statement can cause changes to more than one item property if the additional changes are necessary to complete, or propagate, the intended change. This is included primarily for compatibility with prior versions. The following table shows the SET_ITEM_PROPERTY settings that cause Oracle Forms to propagate changes across item properties:
 Setting this property parameter... To this setting Also causes these propagated changes:
 ENABLED False                                sets the Navigable item property to False
                                                         sets the Update_Null item property to False
                                                         sets the Updateable item property to False

 VISIBLE False                                   sets the Enabled and Navigable item properties to False
                                                          sets the Updateable item property to False
                                                          sets the Update_Null item property to False
                                                          sets the Queryable item property to False

I am not sure what the problem was, but it seems to have disappeared after I removed the set item properties code. I think you are correct about it not being reset somewhere in the form.

I appreciate your help.
