Why this coercion dot on array indicator from strict typedef?

Why is there a coercion dot on the second control?
I created a trivial 3 element array of doubles, and created an indicator by right clicking on it in the block diagram. That's the "CreateIndicator" control.
Then I did the same thing to create a second indicator on the same output wire, and from the front panel selected it and customized it to a strict typedef, saved, and applied changes. That's the "CreateIndicatorThenCustomize" control. It has a coercion dot on it, though. Why?
Thanks to anybody who can shed some light on this for me!

Seems weird that this would be considered a coercion. Why do they do it this way?
Q1)
What is the falicy? Is it that you should avoid coercion dots because they force copies, and yet in this case there is no copying involved so the avoidance advice is incorrect?
Q2)
Also, different question, why is Customize Control grayed out in the front panel Edit menu, as long as another control customization panel remains open from the previous use?
Q3)
Finally, how did I miss this after all this time? Well, you probably don't know how I missed it. Actually, if you do know, it might be better to leave it unsaid anyway....
Q1 Correct!
Q2 Not being NI R&D I can only speculate that is was an expediant move to shut-down that functionality. It used to be possible to customize part of a control while customizing a control back in about LV 6. They shut it down making it more painful to do the edits within edits (you can save a control in one edit and then use "replace" to select it while editing the first)
Q3 I will leave taht question as an exercise for the reader.
take care,
Ben

  • Why do I get this coercion dot?

    I have a strict typedef switch-when-released bool button value change event, and the newval property goes straight into a select.
    Why the coersion dot?  I also get it when I wire straight from the control terminal to the select.  Pause Button.ctl is in 8.5

    Norbert I so hope you are wrong, The boolean True value is defined as '>0', so storing any info in the actual data will make all values true.
    The typdef info is stored in the data-information about the pointer.

  • Why this WLST script does not work from ant a task

    Hi,
              The following is my lovely WLST script to disable managed server hostname verification in a cluster environment.
              It works perfect if I run it from the OS command line,
              java -cp $WL_HOME/server/lib/weblogic.jar sslSetting.py weblogic weblogic t3://localhost:7001
              But if I run it from ant task, it never works. Nothing happens, not even any messages. Any idea?
              ------ sslSetting.py -----------
              # Disable HostnameVerification on managed servers
              # This is a ONLINE script. The admin server must be running
              # @param $1 BEA_USER_NAME
              # @param $2 BEA_USER_PWD
              # @param $3 admin server URL
              if (len(sys.argv) != 4):
              print "usage: " + sys.argv[0] + " domain-home "
              sys.exit()
              beaUserName=sys.argv[1]
              beaUserPwd=sys.argv[2]
              adminServerUrl=sys.argv[3]
              def handleServer(server):
              SSLPath="/Servers/" + server.getName() + "/SSL/" + server.getName()
              print("handleServer(1): " + SSLPath)
              try:
              cd (SSLPath)
              print("handleServer(2): " + SSLPath)
              set("HostnameVerificationIgnored", "true")
              except Exception, inst:
              dumpStack()
              print ("FAILED handleServer(): " + SSLPath)
              else:
              print ("DONE handleServer(): " + SSLPath)
              #===============================================================================
              # Main
              #===============================================================================
              try:
              connect(beaUserName, beaUserPwd, adminServerUrl)
              edit()
              startEdit()
              adminServerName=cmo.getAdminServerName()
              for server in cmo.getServers():
              if adminServerName != server.getName():
              handleServer(server)
              save()
              activate()
              except Exception:
              dumpStack()
              else:
              print ("=== DONE ===")

    OK, when I run the WLST script from command java, I only need the weblogic.jar in the classpath. But I'll need a couple other jar file for it to work inside an ant target, as showing below.
              <target name="run-wlst">
              <java classname="weblogic.WLST" fork="true">
              <classpath>
              <pathelement path="${props.JAVA_HOME}/lib/tools.jar"/>
              <pathelement path="${props.WL_HOME}/server/lib/weblogic_sp.jar"/>
              <pathelement path="${props.WL_HOME}/server/lib/weblogic.jar"/>
              <pathelement path="${props.WL_HOME}/server/lib/webservices.jar"/>
              </classpath>
              <sysproperty key="weblogic.Home" value="${props.WL_HOME}" />
              <arg line="sslSetting.py weblogic weblogic t3://localhost:7001"/>
              </java>
              </target>

  • Coercion dot and strict type definition

    Hello,
    I seem t be having some problems learning how to use strict type defined controls, would someone please help?
    Will you please tell me why the coercion dot is on the subVI's?
    Will you please tell me how to link the  'CtlsToWLp Cluster' from Main.vi and the 'Clust Refnum' from the WLp2.vi to the same .ctl?

  • Coercion dots, Typedef. and Property Nodes

    Hi,
    following problem:
    1. I place a simple Control (Button 1) and connect it to an Indicator (Indicator 1) -> OK
    2. I place a Button as Typedef. (Button 2) and connect it to an Indicator (Indicator 2) -> Coercion dot on Indicator 2 (I don't see the point of a boolean coercion, but OK)
    3. I create a property node for Indicator 1 (Value) and try to connect a constant (right-click>Create>Constant -> the constant is grayed out and the error message is 'type definition not found or contains error'
    Details: The master copy for this type definition could not be found or the master copy has errors. You must find and fix the master copy, or right-click this type definition and select Disconnect.
    4. I remove Button 2 and repeat step 3 -> the same thing happens
    If I connect an existing boolean constant to the property node there is a coercion dot. As a matter of fact for using one Typedef. Control in a VI all other control property nodes suddenly have coercion dots even if I remove the Typedef. control. Does it mean either all controls and indicators better are typedef. or none at all?
    Thanks in advance.
    P.S.: the problem occurred originally in a VI with much more than two buttons...

  • Why can't I create property nodes for item in STRICT typedef cluster?

    I've tried this in LV7.0/WIN2k and LV 7.1/OSX - both versions work the same.
    I have a TYPEDEF consisting of a cluster of items A, B, and C.
    I have a front-panel instance of this typedef.
    Under certain conditions, I want to disable and gray Item C, because it's not applicable.
    So I need a property node connected to item C.
    If the typedef is STRICT, then I cannot create such a property node - the menu item to create anything is just not there.
    If I change to NON-STRICT, then I can create the property node.
    I can change it back to STRICT, and the property node works just fine.
    The question is, if the nodes WORK normally, why can I not CREATE one?
    If there's some sense behind this, someone please point it out to me...

    Blog for (mostly LabVIEW) programmers: Tips And Tricks

    I agree with you, It would be nice to be able to keep the non strict typedef auto-update and extend it to properities which effect the look of a control. I am not sure why you can change the properities on a strict typedef. A strict typedef should have private properities (can only be changed from within the definition and no public other vi scope for writing these values. I have in the past used a custom control for presentation purposes and contained the structure of the data to be displayed within the typedef cluster. This is not all that automatic since we need vi's to convert between the definition and control. Seperating data structure from presentation is much like XML where the file only contains data structure and a reference to a style for presentation. It would be a very nice option to allow nonstrict typedefs to have an additional auto-update properities which could be toggled on and off. I would be curious to here others opinions on how to keep data structure and presentation consistant across an application without being tied down to a strict typedef (allowing the optional change of teh presentation at runtime).

  • Why are red dots next to my music? How can I fix this so my music will play?

    Why are red dots within red dots next to some songs on my phone? How can I fix this so that the music plays and the dots don't just turn grey when I press them? All the music is from CDs not the music purchased from iTunes. Thank you.

    The red circles with squares inside them often mean that the sync with your iTunes went bad.
    Try re-syncing your device. Can you play these tracks in iTunes?
    If a re sync does not work then you may need to rebuild your iTunes Library.

    Unfortunately, this is a problem that is driven by the DRM Dictatorship.  Despite the proliferation of mobile devices and the fact that there are many of us who do a lot of international travel, content providers don't want you to have access to their products outside of your homeland.  The Balkanized mentality of the DRM Dictatorship is way out of touch with the modern world.
    At least Apple, to its credit, allows you to use your accounts outside of your homeland as long as you have the proper credentials for them.  Most other services use the more Draconian geolocation filtering which does require you to be physically present in your homeland.  For the most part, you are not allowed to leave home if you want access to your favorite entertainment!

    Photos from cameras or scans have only one layer (the 'background' layer).
    You can start with that 'background' layer and duplicate it or add other layers in the editing process. For instance you can make a selection of a subject and put it on another layer; a common use is to desaturate the 'background' and to keep the color in the selected subject in your newly created layer.

  • I downloaded Lion on my iMac.  It apparently cleaned out the hard drive.  Nothing shows up from before.  It looks like a brand new computer.  It is backed up on Time machine.  Any idea of why this happened and suggestions on restoring?  Thanks.

    I downloaded Lion on my 4 yr old iMac.  The download stalled at the last minute so I clicked "CANCEL".  When it was restarted, Lion was there, with no apparent option but to go ahead and install so I assumed it was okay.  Didn't transfer data from "another computer" when prompted - assumed it would transfer from that computer.  It apparently cleaned out the hard drive.  It looks like a brand new computer.  None of my apps, programs,  files, or thousands of photos.   It is backed up on Time machine, but it's a sickening sight.  Any idea why this happened and suggestions before restoring?  Thanks.

    I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
    You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots.  Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
    See Pondini's page for more explanation:   What are Local Snapshots?   http://pondini.org/TM/FAQ.html
    I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
    You have tested the library on the external drive, and so your photos are save there.  
    The local TimeMachine snapshot probably now contains a backup of the moved library.  Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.
