  • 30617262 - INTERACTIVE GRID OR REPORT FAILS WITH ORA 6502 ON 12.1 OR 11.2 IF LOV COLUMN HAS MORE THAN 26 CHARACTERS

    If APEX runs on 11.2 or 12.1 (Oracle Identifiers have 30 bytes max), an Interactive Grid column name is longer than 26 characters, and the Interactive Grid column is an LOV column, then page rendering fails with

    ORA-6502: Character String Buffer too small.

    Workaround: in the report query, use a column alias for the LOV column, which is below 27 bytes.

  • 30520385 - INTERACTIVE GRID DML PROCESS WITH CUSTOM PL/SQL CODE USING :ROWID ERRORS OUT WITH "STOP APEX ENGINE"

    If a custom PL/SQL process, which uses the :ROWID alias, is used for a page process related to an Interactive Grid region, then it will raise an error when executed. Upon save, the process will throw "ORA-20876: Stop APEX Engine"

    Workaround: Select the ROWID column explicitly in the SQL query and use a column alias (select rowid rowid_alias, ... from ...). Then use the :ROWID_ALIAS bind in your custom PL/SQL code.

    For Interactive Grids based on a SQL Query, if the query selects the ROWID column and the ROWID column is the first in the Interactive Grid column list, then downloading the data (Actions > Download) fails with ORA-1403.

  • 30489726 - INTERACTIVE GRID REVERT CHANGES IN EDIT MODE LEAVES FLOATING ITEM VISIBLE

    Reverting Changes from the Row Actions menu while in edit mode may causes a floating editing item to be visible in the upper left corner of the page.

    Workaround: Exit edit mode before reverting changes.

  • 30484315 - INTERACTIVE GRID: WHEN REGION IS MAXIMIZED, FLOATING EDITABLE CELL CONTENT DOESN'T SHOW

    When editing an Interactive Grid in a region that is maximized (standard region template maximize feature) any cells that are edited in floating popup are not visible.

    Workaround: Add this CSS rule to the page or in a global app css file:

    .a-GV-floatingItem {
        visibility: visible;
    }
  • 30482266 - SIDE-EFFECTS OF REMOVAL OF JQUERY AUTOCOMPLETE LIBRARY IN PACKAGED APPS

    In the 19.2 development cycle, as part of cleaning our code base and standardizing the packaged apps, we removed all places where we referenced the old 'jquery-autocomplete' JavaScript library. This used to be used by our old 'Text with autocomplete' native item type pre-19.1, and still in 19.1 by the 'Tag Entry' custom plug-in, used in a number of packaged apps. All of the places we used this plug-in in our packaged apps were replaced with the new Popup LOV in 19.2, and we also removed the underlying library from the distribution. However this has had the undesirable consequence that immediately after upgrading to 19.2, existing packaged apps will run into errors on the pages where this was used, because the library has been removed. The affected packaged apps are:

    • Opportunity Tracker
    • Group Calendar
    • Customer Tracker
    • P-Track
    • Data Reporter
    • Bug Tracking
    • Incident Tracking

    Solution for 'Locked' Applications: Simply need to update the packaged app. Go to the packaged application you want to update, and select 'Update'.

Solution for 'Unlocked' Applications: This is a manual process, where you will need to do the following:

  1. Search for all occurrences of the 'Tag Entry' plug-in (you can see all the places it is used by going to the application, then Shared Components, Plug-ins, then select 'Utilization').
  2. Go into each affected page, and switch the item using the 'Tag Entry' plug-in over to use the new Popup LOV item type, with the following settings:
    1. Display Popup As: Inline (default)
    2. Multiple Values = On
    3. Manual Entry = On
    4. Search as you type = On
  3. Once all references have been removed, you can then safely remove the 'Tag Entry' plug-in from the packaged application.

Note: If you had written any custom JavaScript code utlizing the 'jquery-autocomplete' JavaScript library, if possible, we would recommend you look at switching over to using the new Popup LOV item type. Alternatively if that is not an option, you can download the same library that was used, and install that in your environment. It is still available to download here: http://www.bassistance.de/jquery-plugins/jquery-plugin-autocomplete/

  • 30472566 - INTERACTIVE GRID SAMPLE M-D PACKAGED APP -> STACKED WITH SUB DETAILS PAGE THROWS JS ERROR

    Using advanced configuration to disable the gridView of Interactive Grid as is done on page 17 of the Sample Master Detail app results in a JavaScript exception. The purpose is to force the master Interactive Grid to be in Single Row View mode.

    Workaround: Do not disable gridView but let the user manually enter Single Row View or do so programmatically after the page loads.

  • 30461018 - PARSING SCHEMA POPUP LOV ITEM ON APPLICATION SECURITY PAGE DISPLAYS NO VISIBLE RESULTS

    On the Security Attributes page of an application (available via Shared Components > Security Attributes), the 'Parsing Schema' Popup LOV item displays no visible results when opened, which means you are unable to select from the application's available parsing schemas.

    Workaround: You can still enter the parsing schema manually in that item. To see a list of available schemas, go to the SQL Workshop and there you will see the list of schemas in the 'Schema' select list on the right of the page.

Changed Behavior:

  • N/A - JQUERY AND JQUERY UI UPGRADE

    Oracle APEX 19.2 includes jQuery 3.4.1, which breaks compatibility with earlier 2.x versions. If your application relies on removed 2.x, or 1.x jQuery functionality, then this functionality will no longer work.

    Workaround: For applications that still rely on removed 2.x functionality, you can use the jQuery Migrate plug-in. To include this plug-in, set the Desktop User Interface Details attribute Include jQuery Migrate to Yes.

    If your application relies on removed 1.x jQuery APIs, that functionality will no longer work, and you must update the JavaScript to only use jQuery 3.1 APIs.

    Review the jQuery migration guides to learn more:

    For further information including information about the jQuery UI upgrade, please review section 9.1.3 Known Issues for jQuery and jQuery UI in the release notes.
