Run time binding error

ok so i have made a non visual component
with 3 input in properties
1)_input
2)_check
3)_output
it works fine
the problem is when i preview it the output is shown in the cells
howerver when i try to change the checkpropertiy using a button or anythin ..... the value changes but commitproperties is not called and hence the output remains the same
now to check the problem i put an alert statement in the set function of checkproperty .... well that doesn't show .... so basically when i change the values at runtime .... the sette or getter is not called

Thanks, that worked.  I created a utility VI that opens a reference to the main VI, gets the control references, and then applies the binding method.  So the moral of the story for me is that the main VI can be editing programatically or manually.  In either case the main VI is still in edit mode.  Now I can just run this utility VI rather than rebinding all the controls manually each time I push out an update.  I attached an example for anyone who is interested.

  • Run time binding of textfields and the like

    Hi,
    I am working on a dynamic form,which will instantiate questions based on some instructions specified in XML when the form loads up, much like John Brinkman's example
    http://blogs.adobe.com/formfeed/2009/03/a_form_to_design_a_form.html
    At design time, it is not know which node in the data dom the field should be bound to, so I would like to be able to simulate a match="dataRef" ref="$.myNode" statement at run-time.
    However, my recollection is that the binding reference can't be changed at run time. Does anyone know if it can be done, and how to do it?

    Hi Jason,
    Good to hear from you. In our case : "Validate Product data from SAP Enterprise Buyer " has been selected , but Cross -catalog Search is not selected. Though in our case we are dealing with Description Based Item (text item not product item)
    We are communicating to catalog company  about the validity method to support run time validation of price and items from catalog during creation of SC from template.
    So correct my understanding if catalog support validity
    1. Existing item new price in catalog:it will bring new price from catalog while creation of SC from template
    2. Item has blcked for new purchase in catalog: it will shows error in SC like "incomplete items in catalog   or   item doesnt valid"
    3.My default region is X but template for SC region is Y: While creation of SC from template with region Y it will show error that your default region is X  or    create SC w.r.t region Y with validation of Y region based catalogs item and price.

  • Run-Time Engine error

    I have created an automated test and had it running as an executable on a stand alone test computer. I updated my LabView software to 8.6.1. I just made some changes to the test and recompiled it. When I tried to run it on the stand alone computer it gave me an error about the LabVIEW 8.6.1 run-time engine missing. I thought when the project was built all the files that pertained to running it were also built into the folder. Has anyone run into this that could offer some advice.
    Thanks

    Did you create an installer or simply build the exe? If you only built the exe you will need to install the run-time engine on the target machine. If you created an installer you can include the installation of the run-time engine as part of the installer.

  • Custom Run-Time Menu error when named "FileMenu.​rtm"

    Discovered an interesting "feature" (error?) in LabVIEW 2009 when using custom run-time file menus.
    If you create a custom run-time menu (.rtm) and name it "FileMenu.rtm" the menu will not function correctly in executable format.
    In my LabVIEW Project, any VIs which called this custom file menu worked correctly in the project, but when I built an executable, the VIs defaulted to the default file menu.  This was not due to a corrupted .rtm file or the file not being included in the executable.  Instead after extensive debugging I determined that the name "FileMenu.rtm" is somehow reserved in LabVIEW and any executables that are built have the custom run-time menu overwritten by the default.  The tricky part of this error is that it goes unnoticed while the code is still in development and only presents itself after being built into an executable.
    Simply changing the name of the file fixed the executable run-time menu.

    Chris,
    Thanks for trying it out.  It seems that my forum post may have been a bit rushed.  
    I tried to duplicate the problem in a new project from scratch and similarly was unable to reproduce it.  I will try more soon, and in doing so perhaps reveal the true underlying problem.  I would post the original code but it is proprietary.
    I was running LabVIEW 2009 and Windows XP when the problem first presented itself.  I updated to LabVIEW 2009 SP1 as part of my debugging and the problem still presented itself.

  • Run time engine, Error of type 1002208

    Hi,
    I want to build an exe  using LV 8.6 development (project builder).    When I finished the project in LV8.6 development, it works ok.  But When I copy the project (include the exe file) to the computer installed only run-time engine (standard) and Measurement & Automation Explorer, V4.0.0.3010, The screen indicates "  VI has an error of type 1002208, The full development version of LV is required to fix the errors."    Is there anything wrong when I build the application?  Thank you.

    Hi Dennis,
      When i built the application, I didn't build an installer into the project.  I pretty much followed the HELP in LV 8.6 example: Build a stand-alone application.
    The vi is mainly to read the TC signal and voltage signal from the computer connected to a scxi-1000 chassis and modules (scxi-1102 etc.)    Yes, the vi called the sub vi (like DAQmx  Created Channel [AI Temperature-Thermocouple].vi; DAQmx read.vi etc.).  When I built the exe file, I have placed these vis into "always included" under "source file" category.  Thank you.

    Hello Xia
    According to the error log , if you observe one statement " WDDynamicRFCExecuteException " which  you already handled this exception in your BAPI execution method using TRY CATCH block. There is nothing wrong in  the code.
    1) Problem is mainly because of your NETWORK , if the network speed is slow, user's request will not reach the backend ,at that time you will get this error message.
    What to do : Just refresh the screen once , you will get the result , (But you will lose the data if you are in middle of something)

  • LV 6.1, 3D Surface Graph sometimes collapses (doesn't work stably); plus blocks use of remotely controlled panel by LV run-time engine (error #26:"window.cpp", line 11518

    1) "3D Surface Graph" does not work stably; sometimes it changes its properties (e.g. plot style) without me doing anything prior to that; a couple of times it lost a complete sense so that I had to delete the graph and install it again
    2) I tried to remotely run a VI which contains a 3D Surface Graph in it. It turns out, the use of the "3D Surface Graph" somehow blocks the remote control over the panel. As a result of that, I got the following error message: Error #26: "window.cpp", line 11518 (with LabVIEW version 6.1).
    3) Is it possible to plug into the 3D Surface Graph a few plots at
    the same time since there is a built-in control "plot number" (somehow by bundling them up or putting into an array - I tried both but didn't work) or it can be done merely by use of 'case' structure preceding the Graph, where case structure decides which plot to pass into the 3D graph?

    Hello mjoler,
    Thank you for contacting National Instruments.
    The following example will show you how to plot multiple 3D plots on a single 3D graph. Modeling your VI after the example may also alleviate the instability that you have been experiencing.

    As far as the error you are receiving, it's difficult to say what could be causing this. ActiveX controls embedded on a front panel sometimes do not display on a remote client because they draw and operate almost completely independent of LabVIEW. If possible, try remotely controlling your VI with a client computer that has a complete installation of LabVIEW. The error could also be a bu
    g. Try downloading the evaluation version of LabVIEW 7.0 from http://www.ni.com/labview. By doing this, we can determine if it is a bug in the older version that has been fixed in the latest version.

  • Custom Connector Run Time Variable Error.

    Hello community,
    I developed a custom connector to provision users to a target resource.

    Hi,
    given 11.1.1.3 this an old version of JDeveloper, can you create a simple testcase using a newer build e.g. 1.1.1.6 or 11.1.17? This prevents chasing down old issues.

  • Why am I getting Run-time menu error (Error 88 occurred at One or more illegal menu item index in...) in my built applicatio​n (single .exe) , but don't get any error when running/de​bugging it?

    I am using LabVIEW 6.02 & also downloaded the application builder patch. For my runtime menus, I've a subVI that first calls "Delete Menu Items.vi" to get rid of the standard menu items and then "Insert Menu Items.vi" to add my own. I only get an error when I try to run the built application.

    There was a similar issue in LabVIEW 5.0 where you would get the error if you passed an empty array to the 'items' input of Delete Menu Items. This was corrected in version 5.0.1. Did you mass compile your VI's after upgrading to version 6.0.2?
    I tried to reproduce the problem in a small VI but was not successful. I can run an executable built from this example without any problems. I am attaching it for you to test.

  • Debug an applet that has a run-time (logic) error how?

    hi,
    I have an applet that has a non-terminating loop in it...I found it after eye-balling my code.
    How would one debug an applet? I have bought sooooo many books on java, & NONE provide/identify a process for debugging applets. I use JTextPad & would appreciate a method i can use to debug applets....ppppllleezzzz

    TheStijn is correct about stepping thru code - you'd need a development environment. However, the better of these for use in a commercial environment are usually expensive (>$1000). The free ones are not so good (although given that WSAD is based on Eclipse and I think WSAD is pretty good, maybe you could go for Eclipse). They also take some time to get to grips with.
    You could instead litter your code with System.out.println() statements to see what it is doing. These can be viewed from the browser's Java console. On IE, you enable the console by doing Tools > Internet Options > Advanced. Scroll down to "Microsoft VM" and select "Java Console enabled". Then the console is visible (after re-starting IE) from the View menu (at the bottom).
    With Netscape (4.7), you do Communicator > Tools > Java Console. You can also view it on other browsers thru similar mechanisms. Hope this helps in the short-term.
