problems with the link Date variable

I am using a Date as a variable binding in a display object, and I'm running into difficulty. I have the binding variable type defined to date and the control flags for the Type of Format and Format defined respectively on 'Date of Simple' and 'yyyy-MM-dd ". When I run the application test module and enter the date in the correct format, the View object returns the expected results. However, when I try to set a property to bind the query for a group of JHeadstart parameters in my definition of the application in order to highlight the variable to an input dateField control bind, I get the following exception:

However, it seems that the value of the parameter link has actually changed, according to the message issued by the procedure JhsApplicationModuleImpl.applyBindParams (...) debugging:

30 - Jan 08:46:23 DEBUG (JhsApplicationModuleImpl) - ViewObject ViewObj: bind move_date param value has changed: old value = null, new value = Wed Jan 07 00:00:00 CST 2009



One thing I noticed that may be of interest - if I run the debugger in the procedure JhsApplicationModuleImpl.applyBindParams (...), a default date in my link variable arises as an object of oracle.jbo.domain.Date when it comes out of the next line:

Object oldValue = vo.ensureVariableManager () .getVariableValue (key);

as opposed to the new value that is sent from the input value of the dateField control, which presents itself as a java.util.Date in the following line:

Object value = args.get (key);



In the chain of functions leading to the following in the stack trace:

at java.sql.Date.valueOf(Date.java:104)
at oracle.jbo.domain.Date.toDate(Date.java:348)
to oracle.jbo.domain.Date. < init > (Date.java:279)

It seems that the value of the java.util.Date is converted to a string and then passed to these functions to be turned into a java.sql.Date object. However, depending on the function of java.sql.Date.valueOf (...), it is expected date format "yyyy-mm-dd", by the header comments:
/**
Converts the date a string in JDBC escape format to
* a Date < code > < code > value.
*
s @param a String < code > < code > object representing a date in
* in format "yyyy-mm-dd".
* @return a java.sql.Date < code > < code > object representing the
* date
* @throws IllegalArgumentException if the specified date is not in the
* Exhaust JDBC date (yyyy-mm-dd) format
*/

When the input value of the entered dateField control is added as a java.util.Date, the toString() is produce the incorrect date format, that could be seen in the debug output I've included above that says that the binding variable has changed.



Anyone done this before that can has let me know what Miss me and how to fix it? I have search everywhere on the web, and all the articles I've seen related to bind variables only refer to those of the digital types or string, that are not giving me problems. Same article of "5.9 Using Bind Variables Named" Developer's Guide (http://database.in2p3.fr/doc/oracle/Oracle_Application_Server_10_Release_3/web.1013/b25947/bcquerying009.htm) do not reference using a Date type.

I had the same problem on a year (using JHeadstart 10.1.3.2.52):

15 Feb 14:10:31 DEBUG (JhsApplicationModuleImpl) - research component corresponds to the bind param query SubjectenKernPeildatum, value set for 2000-01-01

It appears a java.util.Date is put on the map criteria in the searchBean, this cannot be used as input for a Houston. Bindvariable date.

My ugly solution was to substitute ' public void applyBindParams (String voUsage, HashMap args)
in MyProjectApplicationModuleImp (which extends from JhsApplicationModuleImpl of course).
Check if the value is a java.util.Date, then
value = new java.sql.Date (((java.util.Date) value) .getTime ());

    I have recently upgraded to inDesign CS5 to CS4 and have some documents that I update.  The work links seem to be broken.  I update the links, then the connection breaks again in a few seconds.  I tried to update the original work on CS5, but the problem remains. I have created a document inDesign CS5, placed one of my files have, saved, closed.  When I reopemned the file - I had the same problem with the link.

    My main concern is more with CS5, CS4 and all of my previous work.

  • I have problems with the links and footer

    I have problems with hypertext links (they sparkle and also highlight other text on the page) and also the footer space for always lights in site preview mode, even though I did little master and home page and the following pages.  This happened only after I loaded a file of MUSE in the current version of Muse CC put running up-to-date on the imported file to Muse.  Please help me Adobe Community.

    Once you have opened the file 2014.3 muse you will not be able to open it in a previous version anyway. In order to keep the updated version.

    In this version, Yes, Muse will run an optimization when you open a site. My suggestion is that optimization is made to save the file, so it doesn't have to do it again. I am convinced that a full download should solve your problem. I had a few sites that I need to do a full download myself and all is well.

  • problem with the backup data in text file

    Hello

    The problem I am facing wihile, saving the data in the text file is that everytime when I'm slecting the path of the façade, data that are recorded are added with the previous data, not only in the new text, the new data set is saved but also, is there any previuos run for the program , the corresponding data is also present in this text file.

    However, when I change the same ''(file path) to 'constant' in the control block diagram, and then add the path of the file, it doesn't have this problem. Basically, changing the "file path" constant in the diagram of control block (so that it is displayed in the front panel) is at the origin of the problem.

    Help, please!

    Thank you

    Your shift on the loop Register For is not initialized. It will keep the value of the string since the last time that he performed. That initialize and it should solve your problem.

  • Problem with the links and libraries CC

    Dear forum

    I have a problem that can be solved, hopefully, I see myself as a new user of Indesign and help would be appreciated.

    Since the update to the new version of Indesign, I had a problem when I open multiple files and all the links are missing. These are stored in the CC library in more than a library,

    After attempting to repeat the assets, I get the following message.

    SCREEN SHOT 1.jpg

    I made a copy of the file and open this file without result

    I think it's a question of libraries CC because it seems that the library is unable to find the file, but not 100% sure here, just a guess.
    I am connected to AdobeCC when the message above

    I hope someone can help

    Thank you

    Note: no files where changed or moved the location, including the CC library during the update of Indesign.

    When you have problems with the CC libraries, this often solves the problem:

    When you save a document structured in XML, the Table Continuation variable is translated to an entity named "fm.tcont".

    Strangely, the content of the entity is a control character (0 x 11). The file is saved in XML format, but the Analyzer Returns an error,

    Error message to the file d:\test\100219\doc_test.xml.1F0, line 31, char 22,: Invalid character (Unicode: 0 x 11)

    Parse error on line 31, tank 20: not well formed (invalid token)

    The contents of the variable nothing suspicious, it's just '(continued)', where the first character is a normal space.

    If someone had the same problem and knows how to fix?

    It's on FM8.0p277 on Windows XP.

    Thank you very much in advance,

    Johannes

    Johannes,

    I don't have the direct response, because I've never tried. But my EDD has a TableContinuation element that is empty; ESD inserts the table continuation variable. When you export to XML, the element is there as a "marker"; It has NO content. When open in the frame, ESD inserts the variable again. My reasoning is that the table continuation variable has meaning ONLY within FrameMaker. It's a formatting object, not a content container. No post processing of the XML data would not need if so, ITS engine could provide what it is able to understand.

    Anyway, here's how I deal with it.

    Good luck

  • Problems with the links/e-mail addresses when viewing the PDF in the browser ONLY

    Hello

    I just sent a PDF with an email address in.  There seems to be a strange problem: If the pdf file is downloaded and watched in Adobe Reader, links mailto behind text messaging addresses work as usual (for example. [email protected]). However, when this pdf is displayed directly in the browser (Chrome on Windows 7) by using the built in pdf viewer all double letters in the mailto is deleted (for example. [email protected]), but the text itself remains unchanged.

    There are two examples of that in both cases, the two double letters.

    I just tried a test with ' [email protected] ' as the test address.  Once again, the mailto link shows as "mailto: [email protected]'.»»  Remove the first double letter, but keeping the second!

    Any suggestions?

    Thank you

    Matthew

    Sorry, you will need to file a complaint with Google on this subject; Adobe has nothing to do with the viewer of PDF of Chrome.

    Hi Sebastian,.

    Looking at the file attached vCloud - DC.log, it is clear that the data collector vCloud you use is not vCenter Chargeback 1.5 GA release, but it's the beta version of vCenter Chargeback 1.5. This is probably the reason this vCloud data collector works well for you with VMware vCloud Director 1.0 beta release.

    So, make sure that you use the Chargeback 1.5 GA release vCenter vCloud data collector.

    Once you start using the data collector more recent vCloud, also make sure that VMware vCloud Director 1.0 database to which you are connecting from vCloud data collection has a view defined with name 'CB_EVENT_LIST_RAW_VIEW '.

  • Problems with the use of variables at the time of the SV - Loudness.vi

    Hello

    I'm rather new to Labview and will have questions, get my Time-Varying Loudness calcuations out correctly. Attached is my current VI and a .csv file of my data set (calibrated in PA. sampling frequency = 50 kHz for 5 seconds). It does not produce what I expected when I run the VI. Here are my questions:

    Time-Varying Loudness:

    (1) what are the signals so much? There are hundreds of lines, but I only expect one.

    (2) why my category axis are not a range from 1 to 24 years as bark should be?

    1/3 octave Band Analsysis:

    (1) why is it incorrect? Them should not be a linear increase the frequency...

    Data on the one hand be hurry and make a squeek. It is a transient noise that happens about 2 seconds. But, how could I go do a waterfall (Time (s), Frequency (Hz), Amplidtude (sones)) of this signal? Is there an easy way? or do I have to do all three signals and add to make a parcel?

    Thank you very much for your help! Let me know if you need more infromation,

    -Troy

    p.s. I have included a picture of the results as well.

    Hi Troy,

    (1) the SV specific volume VI 'chunks' given in blocks of 2 ms and returns then these as individual plots specific Loudness vs. Sone.  The colored lines that you see in your chart are representative of the 2 500 2 periods of time ms in your acquisition of five seconds.  Each of these plots contains 241 points, however they are ten sample "gradually", one for each sone.  The digital filter buffer takes a bit to fill and kick in properly, however, so you can give your first rows (0-. 02 seconds or more) scrutiny before using them - you can see a number of unexpected zeros around the lower sones.

    2) since you use a chart, the x-axis will be increments every race following (the previous data is stored.)  If you only want to display the most recent data, I would recommend switching to a chart, which is found in the chart controls palette.  Also, see above (#1) why the x axis are longer than 24 points.

    (3) remember that dB is a unitless measure and cannot be used in reference to another value. A typical reference for sound is 20 uPa, but you will probably need even out your data entry and determine/set dB reference.  You can take a look at the voltage from the snout to the Cloaca EU.vi scale (EU means equalized units) and from the snout to the Cloaca Set dB reference.vi.  In your case, I think the plot of Octave shows your dB from a default value of 1.  The values should be accurate with respect to the other, but you must provide a reference value to calibrate the scale.

    (4) I think that this VI is a good example how to do to create a cascade:

    You will need to break up of your waveform into pieces, just like the specific volume VI, but the basic concept is roughly the same (take piece of waveform, take octave measure of the piece, add octave output measure cluster to cluster table, repeat for the rest of the waveform display)

    Phew!  It was a bit of information.  Let me know if this makes sense and don't be intimidated by the detail and/or unknown functions or methods - you're definitely on the right track, or to ask it to at least the right questions.
