CACHE feature in page regions ?

1) Does everyone enable CACHE in Page definition screen ?
2) using CACHE improves the performance of application ? any instance where you want to turn OFF ?
3) Is there any full instance level setting(global setting) in Apex installation where we can enable CACHE feature all the
page definitions in the entire workspace ?

    Why do I get the "iwork discontinued" message when I click on the share feature in pages?

    If you are using an older version of iWorks, the sharing was, I understand discontinued in July 2012.
    New versions of the iWorks suite, Pages etc now have the sharing option, introduced earlier this year.

  • Save as RTF-feature in Pages 09

    I work a lot with DEVONthink Pro Office, a tool for ordering, categorizing and searching content (mostly documents for me). Unfortunately, while DTPO shows pages files and can even search them, the integration is not complete and leaves something to be desired.
    Working with rtf-files, though, is no problem. Now, when I write in Pages 09, I save my working very often, I usually hit the cmd+s combination on my keyboard after each sentence I write. This, of course, does not work when you want to save as an rtf-file. I have to take the long way of selecting "Export" from the file menu, select "RTF", select location etc. I don't have the foggiest idea why Apple don't just implement a direct "Save-to-RTF" feature in Pages, just as is normal in pretty much all other word processors, but hey, that's just my opinion and, knowing Apple, I do not anticipate any changes soon.
    So my question is: Is there some kind of work-around? Some kind of keyboard shortcut? Possibly an automator action?
    Cheers and thanks for any help given

    Perhaps the reason why the other poster suggested not using Pages for RTF export is that it can make a mess of things. You mentioned citations, and I use legal citations in footnotes. Well if I export a document in RTF format in Pages and then import back into Pages (or something else, OpenOffice or MSWord) the footnotes are a mess.
    Pages does a good job (for me) exporting in .doc format, but it .rtf export function is rather awful (again for me).
    If Pages does a good job of exporting documents having footnotes in RTF for you, then I would be curious as to what version of Pages you are using. I am using 4.0.4.

  • Is there a document outline feature on Pages 5.0.1

    Pages '09 has this neat little feature where i can detail the paragraph style useing the document outline feature. I am looking for this in the newer version of Pages but i can not seem to find it. I do know how to edit the paragraph styles but it is the particular outline feature that i am looking for.
    I'm just hopeing is somewhere deeply hidden in the program where i have yet to look.
    Thanks!

    You know the old saying, if it is free, it is probably too good to be true?
    Apple has removed over 100 features from Pages 5.

    Pages'09 should still be in your Applications/iWork folder.
    Trash/archive Pages 5, after Exporting all your files to Pages '09, and rate/review it in the App Store.

  • Is there a comment feature in Pages for iPad?

    Hey all you iPad owners. Is there a comment feature in Pages for iPad? There is one in Pages '09 that I use all the time. Not having that feature in the iPad version of Pages could be a deal breaker for me buying an iPad. Thanks in advance for your help!

    I think it not an unreasonable feature request for a word prcessor. I feel that in scaling pages down to the iPad Apple has also made the product a little less attractive for professional usage. For example pages for iPad really should preserve Endnotes created elsewhere, but it does not at present. A shame, but we can hope that in subsequent versions of pages for iPad that support or preservation of advanced word processing features is introduced.

    I have cut paste the code from my jsp which is working. There is one additional line. I do not know if that is the cause but there is no harm in trying that out.

  • Very intermittent missing page regions / report rows / page item values

    My goals in making this posting are twofold:
    1. I'm looking to see if anyone else has experienced this type of issue before.
    2. I'm looking for ideas about what can be done to debug such an infrequent bug with serious implications.
    Synopsis
    I'm having a weird problem where very infrequently I will load a page and I'll notice that one or more page regions, report rows, or page item values are missing. If I reload the page the missing parts appear as they normally should.
    By "very infrequently" I would say it happens to me somewhere between 1 in 100 and 1 in 1000 page loads, of course at my last project demonstration in happened twice in 10 minutes to my demo participants. I've attempted to debug this, but most of the techniques I know of involve reloading the page or reposting the form data and (of course) everything looks fine then.
    Environment
    * This has happened on multiple different pages, under ApEx 3.1 (Linux) and 3.2 (Solaris).
    * I believe that so far I've only ever seen this under Firefox 3/3.5 under OSX, but since I do the vast majority of my development with this browser it's not reasonable to conclude that it only happens under Firefox.
    Logs
    * No application errors during this timeframe.
    * Nothing of significance in the database alerts log (just thread notes and log sequences).
    * Nothing of significance in the webserver log (just the usual mod_ossl connection errors).
    Thanks for your attention,
    Jason
    Edited by: Jason G on Jul 24, 2009 12:43 PM

    Well, thanks for reading the post anyway.
    While working through some debugging steps I realized that I was populating some of the regions as the page rendered using AJAX -- this would pause the page rendering until the AJAX request returned. I believe that a hanging AJAX call was the likely culprit of the very intermittent symptoms I was seeing.
    I moved the AJAX calls to the last region of the page and added a javascript function that "watches the page load" by checking for regions by ID and looking at javascript boolean flags to let me know when the page is fully rendered. If this process takes longer than 5 seconds it notifies the user that something happened and offers to reload the page for them in an effort to fix the issue.
    So far, so good -- but it will take a lot of testing to convince me that this case is solved. I hope my documenting this is helpful for others in similar situations.
    Good luck,
    Jason

  • Caching a web page in client machine's Temp file

    Hi Friends,
    I'm struck up with one issue in caching the web page in client machine's temporary internet files. I have designed a secured web application. I used
    <%
    response.setHeader("Cache-Control","no-cache");
    response.setHeader("Pragma","no-cache");
    response.setDateHeader ("Expires", 0);
    %>
    for not storing the web page in client machine. Now only some of the pages that doesn't needs the security needs to be cached in the client machines temporary internet files.
    For that i used the code as
    <%
    response.setHeader("Cache-Control","public");
    response.setHeader("Pragma","public");
    response.setDateHeader ("Expires", 0);
    %>
    Still i'm unable to store. Please help me solve this. Thanks in Advance. Quick help would be greatly appreciated.
    Thanks and regards,

  • Image from database won't display in page region

    I’m having difficulty getting an image stored in the database to display in an HTMLDB page region. I’ve consulted the tutorial in Sergio’s Blog and looked for relevant threads in this forum but am still having problems. Any insights into where I’m going wrong would be very helpful.
    I’m using HTML DB 1.5.1.00.12 and database 10.1.0.2.0 on an x86 machine running Win 2k SP4. My browser is IE6.
    First, here’s the procedure I wrote to display the picture. Although the variable names have been changed this is substantially the same as the procedure in the tutorial:
    CREATE OR REPLACE PROCEDURE download_pic(p_personid in number) as
    v_mimetype VARCHAR2(255);
    v_length NUMBER;
    v_filename VARCHAR2(255);
    v_picture BLOB;
    BEGIN
    SELECT mimetype, picture, SUBSTR(filename, INSTR(filename, '/') +1), dbms_lob.getlength(picture) INTO v_mimetype, v_picture, v_filename, v_length FROM TBLPICTURE WHERE personid = p_personid;
    owa_util.mime_header(v_mimetype, FALSE);
    htp.p('Content-length: ' || v_length);
    htp.p('Content-Disposition: filename="' || v_filename || '"');
    owa_util.http_header_close;
    wpg_docload.download_file(v_picture);
    end download_pic;
    Enterprise Manager tells me that the procedure is valid, and I made sure to grant execute to public.
    Here’s the source for my PL/SQL page region:
    DECLARE
    v_personid NUMBER;
    BEGIN
    SELECT PERSONID INTO v_personid FROM TBLPICTURE WHERE PERSONID = :P5_PERSONID;
    HTP.P('<IMG SRC=”#OWNER#.download_pic?p_personid=’ || v_personid || '”>’);
    EXCEPTION WHEN no_data_found THEN
    HTP.P('No picture in system');
    END;
    When I run the page my region displays properly but I get the red X where my picture should be. A review of the HTTP server’s error log tells me that the server thinks my procedure (HTMLDB.DOWNLOAD_PIC) doesn’t exist. If I create a second PL/SQL page region and set the region source to just the display_pic procedure by itself, using a static number as the p_personid parameter, the picture displays in my browser, but as the only object on the page. Typing the URL http://localhost:7777/pls/htmldb/htmldb.download_pic?p_personid=1 directly into my browser also gives me the “procedure doesn’t exist” error. So I believe my procedure works correctly but somehow my URL in the img tag is incorrect.
    Here’s my marvel.conf file just in case it helps solve the problem:
    Alias /i/ "D:\oracle\product\10.1.0\CompanionCD/marvel/images/"
    <Location /pls/htmldb>
    SetHandler pls_handler
    Order deny,allow
    Allow from all
    AllowOverride None
    PlsqlDatabaseUsername HTMLDB_PUBLIC_USER
    PlsqlDatabasePassword @BTV4hSLn+NKXXGs045hwqYeJ+u2gWjROPQ==
    PlsqlDatabaseConnectString BE4013882062404:1521:Robert ServiceNameFormat
    PlsqlDefaultPage htmldb
    PlsqlDocumentTablename wwv_flow_file_objects$
    PlsqlDocumentPath docs
    PlsqlDocumentProcedure wwv_flow_file_manager.process_download
    PlsqlAuthenticationMode Basic
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8MSWIN1252
    Again, any assistance that anyone can provide would be very helpful. Thanks!

    Robert,
    please describe your task correctly:
    You want to create a link (in report) with download image capability, or you need to SHOW image in report? This is a bit difference tasks.
    I solved this tasks, you can do both capability in one report. It easy.
    1. wpg_docload procedure can be used only for download image/BLOB, not show it.
    2. For both download/show BLOB you need dual link with two different procedures. One with wpg_docload call for download, another for show with htp.prn (not htp.p!*) call for show. Then you can create call both procedures from your SQL repors select.
    3. Viola, all works perfectly.
    *Note: htp.p inserts newline after every block of BLOB, so JPEG with size> 32K will be incorrectly shown. htp.prn makes uninterrupted output without newline insert.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • Caching in Dynamic Pages

    Hi,
    I have created a dynamic page(HTML) and published it as a portlet. I have included a call to display an image(say xyz.jpg) in the code. I have also published this dynamic page as a portlet and use it in a portal page. When I view the page it shows the image. When I change the underlying image(xyz.jpg), the new image(please note that that the images are different but the path and file name are the same) is not showing up in the portal page. Instead, the old image file is displayed. I have given Don't cache for the portal page. I also tried clearing cache for the page group, portal page and the dynamic page and it still displays the old image and not the new one. Is there a way to clear cache dynamically?
    Thanks,
    Manikandan Vembu

    Hi,
    This is a known issue with the way Wordpress generates the URLs to included content:http://forums.adobe.com/message/4774943
    Wordpress generates absolute URLs to content rather than relative URLs, so the current workaround is to either use relative URLs or, if that's not possible, modify the wordpress configuration to use the IP address instead of localhost.
    Hope this helps,

  • Clear Cache of a Page using Tabs

    Hello,
    my problem is, that i want to clear the cache of a page, when the user accesses this page by clicking a tab.
    So my Page has six items, which are used to search people in a db.
    Under the items is a submit button, which submits the values in the items and the same page is loaded with the search result.
    But when i go on another page and click on the tab of the "search-page" the result is still there.
    Because of the submit button i can not create a process which clears the cache when the page is loaded....
    I hope you understand my problem,
    Thank you,
    Tim

    This is not possible using the built in Apex tabs. Apex tabs are meant to quickly switch between pages with all your session state intact.
    You can do what you want if you use a List instead of tabs. You have full control over List entries and you can clear cache for the list target page, set other items as needed (you can control the full f?p= URL)
    Hope this helps.

  • Determining page region through FacesContext

    In 11g, what's the best way of determining which region (jsff) is currently being used ?
    In 10g to provide conditional "Requery Condition" I used to use #{facesContext.viewRoot.viewId} on the group to check if the table or the form view was being used. This works fine for standalone pages but not for the new regions. How can I accomplish the same thing ?
    The other place I need this functionality is for wizards where I am re-using a detail group between two different wizard pages (regions). On the entry page, the detail group is to be editable but on the summary page the group is to be read only. For this I could of course duplicate the detail group, make one editable and one read only and use different groups on the different pages still pointing to the same data collection. I would rather set the "Update Allowed" property such that I could use the same group in the two different regions.
    Many thanks !
    Cheers,
    Brent

    Brent,
    You can use
    #{controllerContext.currentViewPort.viewId}
    this will return strings like "/EmployeesTaskFlow/EmployeesTable" for the table page, and "/EmployeesTaskFlow/Employees" for the form page.

  • Creating Items in Personalize Page region (HTML Pages)

    Hi All,
    Has anyone ever ‘created an item’ in the Personalize page region in Oracle HTML pages (IE: iProcurement)...or more to the point; does anyone know how to?
    I have a DFF on requisition lines that I want to make context sensitive based on the supplier used in the requisition header, and ideally I would like to set it up within the Application.
    From what I have read on other forums and blogs this can be achieved by created a ‘Boolean item’ based on the supplier and then referencing this item in the ‘required’ properties of the attribute (using SPEL).
    Unfortunately I have fallen at the first hurdle as I am unsure how to create the Boolean Item (I have tried – but am unsure what to fill in on the form), can anyone give me any advise (hints, tips, step by step instructions etc) on how to create an item that returns True if the supplier ‘X’ is selected (otherwise return false)?
    Regards
    Carl

    you might have chosen an automatic sort in the region properties, for thoses where you cannot arrange items.
