• Search fields added during execution

  Hi all

  I use Jdeveloper 12 c on internet explore 10 with 11g database on 64-bit.

  I followed the link as a tutorial.

  Oracle JDeveloper 12 c (12.1.2) tutorials - developing rich Web Applications with Oracle ADF

  step 8

  Develop control data EmpDetails1 and expand the node named criteria below him. Select all the searchable attributes and drag it to the new page query.jsf . Create it as a query > Panel request ADF.

  I had two problems

  1. the generated fields are too big, I want to control their width, but I don't see any field in the search box, instead, I see "search fields added during execution.

  2. I want to o excluding some areas. How to make since I can't see any generated field.

  Kindly guide me with this.

  Thank you.

  (1) the width of the fields is controlled to the view object. To change the width, you change the width to display the attributes in the suspicion ui tab.

  (2) this ID controlled of the view object. To hide an attribute in the query panel you uncheck "queryable". See JDEV: af:query hide some attributes of query panel but show them the results table | JDev & ADF Goodies

• ORA - 06502:numeric or of value errORA-04088: error during execution of trigger

  I received the following error message by entering a number in the maximum value (i.e. 9 999 999.) allowed in a data entry form that is distinct from the basic form:
  
  ORA-06502: PL/SQL: digital or error number precision value: ORA-06512 too big: "< owner >. < trigger >", line 194 ORA-04088: error during execution of trigger '< owner >. < trigger >.
  
  Where < owner > is the schema name and < Trigger > is the name of the trigger. The block of data in the application for participation is based on a database table, and the sum of all the values entered (with a maximum value of 99.999.999.) appears in the form of Basic. A grand total of this amount along w / other totals on the basic shape is also displayed with a maximum value defined as 999 999 999. Only, I get the above error message when the total is greater than 99999999. If the total is less than or equal to 99.999.999, the basic form works very well. Why?
  
  I checked all the attributes of the database columns and form fields and everything seems to be okay, and I'm out of my mind. I desperately need your help to solve this problem quickly because the pressure is on...
  
  Thanks in advance for any help.

  Hello Hamid,

  Thanks for your help. Yes, it works as suggested, after that I have increased the length of NUMBER data base table column (9) to NUMBER (11).

  gives you the correct answer, and you don't mark it ;)

  >

  Apparently, Oracle database truncates the decimal points and only update the value of 9 digits without giving errors, but the form of Oracle application is more picky and it generates forms and Oracle error messages when you run the application. It seems that there is a difference when executing the sql commands in the Oracle database and execution of these Oracle Forms application controls. Do you agree?

  Yes

  Thanks again for all the help.

• Adding series to the table during execution?

  Newbie :-)
  
  I'm trying to add series to a chart during execution because the number of series to draw is variable and only determined once the XML of a HTTPService returns...
  
  My chart looks like this:
  
  < mx:PlotChart id = "mainChart" showDataTips = "true" width = "100%" height = "100%" >
  < mx:series >
  ...
  
  If I add:
  
  < mx:PlotSeries xField = "Size" yField = "CompetitorPrice" displayName = "Competitor price" / >
  
  then the data plots OK, but try to create the same AS serial does not work (nothing appears):
  
  var newSeries:PlotSeries = new PlotSeries();
  newSeries.xField = "size";
  newSeries.yField = "CompetitorPrice";
  newSeries.displayName = "SeriesAddedAtRuntime!"
  mainChart.series.push (newSeries);
  
  Debugging presents the new series added and it seems OK... but it does not appear on the graph. No errors.
  
  I tried mainChart.executeBindings (); and mainChart.validateNow (); with no chance, but I guess as to what is to be the case here, as you can probably!
  
  What Miss me something to force an update of the chart with the new series added?
  
  Thanks in advance
  
  John

  It is not displayed because the table is not aware of the change in ownership of the series. I think that to run the following steps (give an or take a few syntax errors):

  var set = mainChart.series;
  var newSeries:PlotSeries = new PlotSeries();
  ...
  Series.push (newSeries);
  mainChart.series = series;

• masking steps during execution

  I have a sous-suite that I point the user to when asked to isolate a card failure.  To give them some flexibility, I got a popup that gives them a certain number of options (see attachment).  I have an m.o. that indicates the individual steps these select/run (i.e. '1' or '3' in the png).  Control flow (denoted by '2') is the noise they don't really need to worry and may / will cause confusion (and possibly problems for me if they select them accidentally).  Is there a way to hide these measures flow during execution control so that the user sees '1' and '2' (and other similar 'valid' selections?

  If there wasn't a need explicit to have the flow control logic, then I'd be tempted to compact all in the post of the Popup Message action.

  

  By setting the Popup Message Action to go to the step, , use Custom Condition (TRUE):

  

  And by using the following Expression:

  Step.Result.ButtonHit == 1? RunState.Sequence.Main ["MR_RPack_R55"]. UniqueStepId:
  
  Step.Result.ButtonHit == 2? "" "RunState.Sequence.Main ["End_PCI_Isolation"]." UniqueStepId:
  
  Step.Result.ButtonHit is 3? RunState.Sequence.Main ["MR_R103"]. UniqueStepId:
  
  Step.Result.ButtonHit is 4? "" "RunState.Sequence.Main ["PCI_Intf_PT"]." UniqueStepId: «»

  It should be appropriate level following the Popup Message.

  (SequenceFile attached).

  I hope this helps.

• Edit/delete/add scene coordinates in the table during execution

  Hello world

  I managed to build table allows you to store and record the coordinates of the stage and remind to control steps. However, I need change/remove/add details of scene during execution. I also need to allow the user to directly edit the coordinate from the scene of the array. Wondering what someone knows what is the best way to do it? Or is it better to use the matrix or Cluster? Thanks in advance.

  Best regards

  Thanks much altenbach for all the advice. I tried to do a table 2D control. I've been playing with table in the control. However, I still can't find out how can I detect that I change the data in the table 2D with the more recent issue during execution? How can I then update my current table with the latest data?

  Well, the 2D table is updated immediately and you do not all the other tables.

  Do you mean that you want to update XAbs, etc. where the just changed line is already selected?

  In any case, here's a simple project, perhaps it will give you some ideas. I would recommend using also the tables for XYZPos, entrances etc. and the XYZabs. This simplifies the code because you reduce the number of terminals and table operations.

  Let me know if something is not clear to you.

• Disable the extended FIFO FPGA target during execution

  Hello

  I use a FIFO extended target in my FPGA to constantly calculate the derivative of a measured value (dB/dt). Thus the FIFO stores all values during time dt. This means dt determines the number of items in the FIFO and dB is determined by the actual value less the oldest value in the FIFO. It works well when I initialize with the code in figure InitFIFO.

  But the FIFO of compensation is not possible (see figure clearFIFO). In the while loop if "reset dB" is false, as the new value of B is written on the FIFO, then the oldest value is read from, for the number of items in the FIFO remain constant. To change dt during execution, I need to clear the FIFO and initialize it with a new length (number of items). I tried the next loop, but it does not work. The FIFO does not initilized with the elements. The length is zero and the loop counter for (#deltaB Length2) is 0.

  What I am doing wrong? Is there a better way to erase a FIFO during execution in the FPGA? I'm now stuck for 2 days with this problem and looking forward to any idea or suggestion.

  Thank you very much. Best regards

  Andy

  Hej,

  Thank you for your response. You were correct, that deltab FIFO length was 0 because the defalt value was zero. The problem is that in my host vi on the RT system I put DeltaB FIFO length in a loop of high priority and as you can see when I restart the FPGA, DeltaB FIFO length has a valid value (the code in figure 1 works well with a local variable of DeltaB FIFO length in the FPGA). But the variable to set the variable "reset dB" is under the control of the loop of low priority of the host vi. And there, I had an entry DeltaB FIFO length unwired.

  So, I learned that a control FPGA read/write unwired sends a '0' or resets the variable to its default value in the FPGA. I assumed that nothing is transferred and the last variable is retained if you let a control read/write unwired. Now, I learned of this stupid error!

  Thanks a lot again!

• modify VI during execution

  Dear users of LabView,

  I have a fairly general question about the development of a project, which requires a continuous control of the material. To be more precise, I develop LabView control and DAQ software for calorimeters in high volume in the last 2 years. Such a system requires several PID controls, and it has many subsystems. Because of the large heat capacity, it takes about 3-4 days to launch the system. So if I need to edit for example something in control of the final of a specific subsystem, I stop the LabView code, I have change the specific part, I restart the system, I wait for 3 days, and then I can see the result of my changes.

  My question is the sort of General: what is the good, let's say "best practice" to avoid such a dead time?

  Is it possible to change a VI during execution?

  I understand that if I run the independent screw, that dealing with subsystems, I could avoid this problem. But if I already have a compact 'main' VI, including all the subVIs, what can I do?

  It would be nice to have a sort of "hot swapping" feature in LabView, so during the execution of main VI of my project, I could change the Subvi that I want, and when it is ready to activate, the runtime would swap with the old version.

  Thanks for the tips and advice!

  Best wishes

  Hello

  It all depends on how works your vi...

  The only way I see is to use dynamic calls: a vi called dynamically is editable even if appellant vi is running.

  If you change the callee until the caller calls the vi vi.

  Is how the appellant under vi (this includes the values of connectors and run the VI):

• How to change the frequency of sampling DAQmx during execution?

  Hello guys. I'm using LabVIEW in the measures of the frequency response function. My application requires the sampling rate to change according to the frequency of the signal during execution.

  I tried to do it with a "structure of the event" and it works well when I change the rate manually via the front control but it backs do not work when I set up the sampling frequency to vary automatically (just a frequency sweep). Photos below:

  Why not the structure of the event feels the change in the value of "rate"?

  Thanks in advance for your help.

  Lucas

  Hello

  In "automatic mode" to change the sampling rate, the calculated rate is written in the local variable (as illustrated in the code).  Structure of the event does not change value in the local variable as an event.

  In order to make the structure of the event to recognize the change in value of an indicator such as event: write the new value to the property "Value (Sgnl)" corrosponding node to rate indicator (see figure below).  This will make the structure of the event accept the value change in the indicator as event.

  Note: Use architectures such as producers and consumers for such applications, which makes the application readable and expandable.

  See rear queries if any.

  

• Use of LabVIEW memory grows slowly but continuously during execution

  Hello

  I am having trouble with LabVIEW. I develop a data acquisition application. My application acquires data, it (i.e. make a FFT) processes and displays the FFT and samples acquired in some graphics.

  The problem I have encountered is Labview is allocation memory more every minute of what my program is running until finally, it crashes. When starting my program uses about 400 MB of memory after 4 minutes approximately 1.2 GB. Sometimes, when the memory usage reaches 1.2 GB it is suddenly up to 500 MB, but most of the time Labview crashes.

  I already checked the tool 'Profile Performance and Memory'. Surprisingly, my screws have constant use of memory during execution.

  Someone has an idea, what happens?

  Kind regards

• change the frequency of the signal during execution

  Hi, I'm working on a VI to calculate excess of signal I think VI seems to be good (not sure) but now my problem is

  change the frequency during execution, which I am not able to do only when I stop and run the vi frequency changes... pls

  someone help me I tried to put in an event... but no use... maybe iam missing something pls help me...

  I noticed that you have some time a loop around the entire block diagram - I'm not entirely sure why that is.  The way you have your VI wrote that the two inner loops will never come out unless there is an error-'stop' buttons are hidden.  Thus, the outer loop is not do anything for you.

  Once you take it, it is easy to see why you cannot change frequency.  It is defined once, outside of the loops and so never gets checked again.  The best way to resolve this, in your case, is to use registers with shift on the upper loop and check if the value of the frequency has changed since the last iteration.  If so, generate a new waveform and feed DAQmx writing instead.

  See the version annexed to your main VI for what I mean.  (I also replaced the controls to stop with one that is visible and which will stop the two loops without your duty to hit the button abandon.) I'm also an error on the DAQmx read in the loop at the bottom, but I'm sure it will work fine on your equipment.

  See you soon,.
