Hi, I have a block with several items.
Some are on a content canvas and three are on a stacked canvas.
This stacked canvas is hidden until shown.
Both canvases share the same window.
All items are based on the same table.
When I query the block, the items on the content canvas
are displayed, but when I click the 'more' button to
display the stacked canvas, the items for the records are
not displayed until I click on the item of a record.

The 'more' button has a

go_item('blocka.first_item'); --first item on stacked canvas
show_view('stacked_canvas');

for when-button-pressed trigger

How do I get the items on the stacked canvas
to display?
The displayed properties of the items are
set to 'True'.

Try to add the commands 'synchronize' and 'redisplay' after the show_view-command. Sometimes Forms needs a hint that it should show not only the canvas but also the items on it.

Tried both synchronize and redisplay after show_view and get same result.  Also tried a cursor and set the item to equal the rec values...same result.  Any other suggestions?

You can also try to jump to an item on the canvas right after showing and then jump bakc to the item you came from.

Ok...I've identified problem.

I am using the same stacked canvas for the same items
that are in three different blocks.

ie. pt_lodge, etc are items in member block, block b and block c.  I've created two more stacked canvases to show these items as needed.  

Thanks for all your help!
