In previous versions, the condition was evaluated right before each region was displayed. Use computations or PL/SQL processes to set session state before any region is displayed. In that scenario, the condition has already been checked before the display point is rendered. However, this will not work if a PL/SQL based region sets session state which is then used in a subsequent region condition to determine if the region should be displayed. The regions where the evaluation returned true will be executed and displayed. In Oracle Application Express release 4.2 due to changes for the new grid layout, when a page is rendered, all regions in a certain display point are evaluated before rendering that display point, to find out if they should be displayed or not (so that the grid layout knows how many columns to render). For behavior that matches earlier releases, set the Compatibility Mode to Pre-4.1. To enable these behaviors, set the Compatibility Mode to 4.1 or later. Is the page item not of type Display Only where Save State is set to No? Is the page item contained in the POST request? For example, if the page item is conditional it will not be contained in the POST request if the condition evaluates to FALSE during page rendering.

Note that these are the same checks which occur before an UPDATE. The code which performs the INSERT was changed to determine if the columns should be included in the INSERT statement. Applications running in Compatibility Mode 4.1 or later respect the specific Browser Security attributes.Īlso, in Oracle Application Express release 4.1, because of bug 12990445, the following changes were implemented for Automatic Row Processing (DML) process types. Applications running in a Pre-4.1 Compatibility Mode function as if the Cache is enabled and as if Embed in Frames is set to allowed. The Embed in Frames attribute controls if the browser displays your application's pages within a frame. Enabling the Cache attribute enables the browser to save the contents of your application's pages in its cache, both in memory and on disk. Prior to Oracle Application Express release 4.1, an invalid column name of the source of an item would not raise an error when rendering the page but it would also not set session state of the item.Īlso, in Oracle Application Express release 4.1, there are two new application Security Attributes to control Browser Security: Cache and Embed in Frames. In Oracle Application Express release 4.1, Automatic DML forms raised an error when rendering the page if the column name of the source of an item was invalid. Property Editor Change Indicator - Changed attributes display with a blue marker until the page is saved. Property Editor, Filter Properties Search - Search for a group or an attribute in the Property Editor by entering keyword in the Filter Properties field.

Two Pane mode enables developers to focus on two panes at a time.ĭrag and Drop Tab Reordering - Developers can now customize Page Designer by reordering tabs within and across panes. Two Pane Mode - Page Designer now enables developers to view just two panes instead of three. Similar in appearance to Legacy Component View, the Page Designer Component View tab presents user interface elements and application logic by component type however, when you click a component, the Property Editor highlights the corresponding attribute in the right pane and enables you to edit the component attributes. Page Designer includes a number of key enhancements:Ĭomponent View Tab - To assist developers with the transition to Page Designer, Page Designer includes a Component View tab.
