Does JSTL functions work in custom Spaces Page Style ?

I am trying to create a custom page style and have to write some logic where I have to use fn:containsIgnoreCase. When I create pages that use this Page Style, it throws a white page and doesnt work.
I have also added the below in the root
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
xmlns:c="http://java.sun.com/jsp/jstl/core"
When I remove the fn:containsIgnorecase, It works fine.
My version of Webcenter Spaces is 11.1.1.6

Hi.
You can use JSTL perfectly in ADF. I don't share the opinion of Oracle not recommends... there are a lot of official pages saying how to use JSTL in ADF.
<af:outputText value="#{fn:length(yourList)}"/>Yannick is saying that you can't mix lifecycles. Take care using $ or # operators :).
For example if you are using a JSTL c:forEach. Next code is going to crash:
<c:forEach var="..." value="${list}">
   <af:outputText value="#{list.item}"/>
</c:forEach>Because # is evaluated in prepareModel phase and $ while rendering.
I hope this help you.

    Yes, it will work. Just double click the Time level (say year/month/week), mark it as a chronological key (on keys tab). Use that in your AGO function

  • Does ORACLE functions work with Oracle Database 10G

    Hi,
    I am wondering if ORACLE functions work with Oracle Database 10G or is it mandatory to use OCI functions?
    Thanks in advance!

    I was able to run a simple query with ora_* functions using 10g on Windows.
    The Oracle OCI calls used by PHP's ora extension still exist in the Oracle 10g libraries
    But I cannot recommend this obsolete extension.

  • How does ISNULL function works

    I understand that when appy the ISNULL(@MYVAR,0) if  @MYVA is null then the return value would be 0. 
    But how does this works
    ISNULL(5,15)  Value return =5
    ISNULL((@MYvar, 0) Where @ MYvar=3 VAlue returend =3
    I did not get how does two above statements are working.
    Thanksi am a novice and a student

    Hi Zongqing
    The output of below SQL statements is driving me crazy. Please can you help me understand the contradictory behaviour of ISNULL function.
    --starts
    DECLARE @WebBased INT
    SET @WebBased = 0
    SELECT ISNULL(@WebBased, '')
    SELECT CASE ISNULL(@WebBased, '') WHEN '' THEN 82 ELSE @WebBased END
    --ends
    may be this will make you clear 
    DECLARE @WebBased INT
    SET @WebBased = ''
    SELECT @webbased
    since INT has higher precedence over char , therefore the empty string is converted to int with value as 0
    Thanks and regards, Rishabh K

  • Does sdo_relate function work for 3 dimension geometry?

    Hi,
    I've read in Pro Oracle Spatial book that Oracle spatial operators work only for two-dimensional geometries, except SDO_FILTER (pg 257).
    I always declare geometries data in 3 dimension, like that:
    MDSYS.SDO_ELEM_INFO_ARRAY(1,3,1), MDSYS.SDO_ORDINATE_ARRAY(-42.4149263501948,-19.409108499099,0,-42.4142138531992,-19.4092962878525,0)
    Sometimes SDO_RELATE works, specially if it is a small polygon or a perfect square.
    I need to prove to my boss that we have to work with 2 dimension, but he is arguing that if sometimes it works is because I'm doing something wrong when SDO_RELATE doesn't work.
    Thanks for any help.
    Best regards,
    Luiz Soares

    Hi Luiz,
    If your data is 2d you should only be declaring it as 2d.
    In Oracle 10g and earlier, sdo_relate only works on 2d data.
    If you create a 3d index by explicitly creating your index with sdo_indx_dims=3, then sdo_relate is disabled.
    If you create a 3d index as above, sometimes sdo_filter can actually return the same results as sdo_anytinteract. For instance, if you are using non-geodetic data, there are some cases (rectangular polygons aligned along x,y, and z axis, points, some combinations) where this is currently true.

  • Does Firefox Home work with custom servers with a self signed certificate?

    I've setup my own custom Firefox Sync server which has a self signed SSL certificate.
    When I try to connect to it using Firefox Home I get the error:
    Cannot Sync - Failed To Communicate With Server (1)
    Firefox on my Mac and Windows laptop Sync fine with my custom firefox sync server providing I create an exception first. But no such luck with my iPhone.

    Access your server with ssl using https://<servername> . Firefox will warn you about untrusted certificate, and suggest you to add an exception. This exception will work for firefox sync too.

  • Does Search Functionality work in SAP without having TREX

    Hi,
    Can we have Search functionality in SAP Netweaver without having TREX installed in the landscape because we are facing some problem  installing TREX in Customers' landscape. They are having Windows Server 2008 R2 based on IA64 bit archtecture as OS. Although SAP is proving Trex in Service Marketplace for IAA32 bit machine, but they are not providing any Software packages for IA64 bit. Is there any other alternatives we have to get the search service in SAP.
    Our ECC is in EHP5 environment.
    Thanks in advance.
    regards,
    Soumen

    Hi Soumen,
    If you are using e-Rec or Talent Management then you need TREX for searches. STVN SuccessionPlanning uses Talent Management searches, so indirectly it also needs TREX.
    Best regards,

  • Why does fix capitalization work when there is only one space after the period in pages 09?

    why does fix capitalization work when there is only one space after the period in pages 09?  For example:  "Turn on 3rd St. After the traffic light."  There is only one space after the period in "St."  shouldn't it only auto correct after TWO spaces..??  the word After, should be after..

    You may also use a noBreak space after the period at the end of the abbreviation.
    If I remember well, in such case the capitalization will not apply.

  • Scroll over highlight function not working on custom nav bar links

    Hi - I've created a custom nav bar in iWeb (www.HollywoodRC.com). I have it set up so that the text highlights when scrolled over. This function works in iWeb but does not work on my published site in Safari; however, works in my published site on IE. Any ideas on how to get the scroll over highlight to work on my published safari site? All the links work properly.
    Thanks,
    Steve

    No. Things must have changed. I created a hyperlink with a non web safe font, LedgerD, added a drop shadow and published. I also put the same link in a shape. You can see them in this test page: Page-1 . The two items are image files but they do not contain the link text. Very strange. The hyperlink text can't be selected nor dragged to the desktop like other links, like the Click to Play links on the page, however.
    However, I don't know how IE will handle it. According to this IE emulator site, http://ipinfo.info/netrenderer/, IE can see the drop shadow. But it doesn't tell us how the links will work.

  • When I try to send a link to a page from Safari, I get a message saying that sending the message to the server failed.  It places a copy in the outbox.  All other email and safari functions work properly.  Ipad 2 IOS 7.1

    My Ipad2 works fine except when I try to email myself a link to a safari webpage.  I get an error message saying that the message failed to connect to the server.  It says that a copy of the message has been left in the outbox.  I cannot get the message from the outbox.  All other email and safari functions work as expected.
    I have cleared data and cookies, powered down, and done a reset.  Nothing seems to help.

    Typing in additional text seems to get the job done.  This seems to be a feature of the latest IOS update, I have never had the problem before the last update.
    I use the box with the arrow just to the left of the URL block at the top of the page to send myself links to pages of interest.  Adding the extra text seems like a pointless step, but it does work.
    Thanks.
