Question
The Orders form has four blocks. The Orders and Order_items block are on the CV_Order content canvas; the inventories block items are on the CV_inventories content canvas; and Control block buttons are on the CV_Buttons toolbar canvas. All buttons have mouse Navigate set to No. The Order_Items block is a detail of Orders. The inventories block is a detail of Order_Items, showing the stock of the selected product. There is a button in the Control block with a When-Button-Pressed trigger: IF GET_CANVAS_PROPERTY(:SYSTEM.cursor_item, item_canvas) = 'CV_ORDER' THEN GO_BLOCK ('inventories') ELSE GO_BLOCK('orders'); END IF; When you run the form and click the button, navigation does not occur, and the form displays the runtime error "FRM-41053: Cannot find Canvas: invalid ID."
