• How to use Type Casting in the JSF Expression Language

  I have a CategoryId attribute in my original Version of type oracle.jbo.domain.Number. I am using the expression of the Boolean element in JSF as #{rank. CategoryId! = 4}
  Here the JSF code:

                        <af:column id="s141NewItem3Col" noWrap="true" width="100"
                                   rowHeader="false">
                          <f:facet name="header">
                            <af:outputLabel value="CAtIDDeq4" showRequired="false"
                                            id="ol18"/>
                          </f:facet>
                          <af:inputText id="s141NewItem3"
                                        value="#{row.CategoryId != 4}"
                                        label="CAtIDDeq4" required="false"
                                        readOnly="#{((pageFlowScope.ContractRightCategoriesTable.newRow) and (!(jhsUserRoles['RM, ADMIN, AllButTitl, AllButAdmn']))) or ((!pageFlowScope.ContractRightCategoriesTable.newRow) and (!(jhsUserRoles['RM, ADMIN, AllButTitl, AllButAdmn'])))}"></af:inputText>
                        </af:column>

  I get the run-time exception "Cannot convert type oracle.jbo.domain.Number class 4 to class java.lang.Long".
  
  I wonder how the line. CategoryId is considered to be Long? Please notify. Also, I'll be able to use type cast expressions in the JSF Expression Language?
  
  Thank you, Pradeep

  Use the attributeValue
  Try * #{row.bindings.CategoryId.attributeValue! = 4} *?

• Type cast using the Console Design

  Hi all
  
  I am using the function java.util.Hastable.put (key, value) using the OIM design console. The function expects two objects as parameters to the card. I want to map a string to a string. While the string is a subclass of the object, IOM design concole does no direct mapping. Variables of type other object will simply not available in the menu dropdown.
  
  Q: How have the input parameters when the expected type is a superclass of the real parameters, using the console of design ?
  
  Kind regards
  
  Jan Willem

  There are com.thortech.xl.util.adapters.tcUtilHashTableOperations utilities that can help you to create and add values in a hash table. You can find the documentation in the java docs included in the location SDK\javadocs\util.

• Access and manipulate elements of the cluster

  I have a group of 4 elements. One of the elements is a ring with 4 data entry. Is it possible to manipulate these entires 4 data based on a condition?
  For example, when a condition = 1; then 3 ring entries will be disabled and grayed out. When not, all 4 entries must be enabled.

  Is it possible to get the local variable for those inputs of the ring in a cluster. or ideas?

  

  Hello

  When you right-click the control of the ring, you will have a Create-> property Node-> disabled]

  AS LONG AS you call the command is not strictly Type Def or the cluster that contains the control of the ring is not strictly of Type defined, you can use property "Disabled items []" to get the behavior programmatically.

  When a condition is true, the index numbers of items that need to be disabled for this hardware node of wire.

• How to convert an array of string elements to a cluster with elements named different data types?

  I'm looking for more help with the conversion of an array of elements of the chain in a cluster containing elements named different data types.

  I am importing data from an Excel worksheet.  He is coming in LabVIEW as separate (channels) 3 tables: 1) Variable name, (2) three possibilities Int, double, String) data type and the value 3), with the clues in each table corresponding to a separate variable (I have about 180 variables to import).  My ultimate goal is to convert the string array of 'Value' in a cluster.  But I want the correct data type in the cluster and I also the elements of the cluster name to match with the string 'Variable name' table so that I can use the Unbundle based on the name in my main VI.

  Please see attachment a Subvi for more details.  I did the size of the new items of tables 5 for simplicity.   I realize that labels property cannot be changed during execution and I don't think I need to do.  I just want to use the production cluster (mainly the unbundle by name) to help design my main VI.  I will need to 'read' and 'write for' the cluster during execution, but I won't need to change the names of the items.

  I was also wondering if there is a better way to import data from Excel?  Is it possible to import directly into a cluster immediately rather than put everything as strings?  I have attached a Subvi showing how I currently bring in data (found on the forum somewhere).  It comes as table 2D, which I divided into 3 separate tables that I mention above.

  I am open to any suggestion.  Thank you very much.

  Instead of trying to create a cluster, I think I would use only variant attributes.

  

• Build the cluster array function

  Why that different types of data can feed a package, but the function Array of Cluster build only accepts one type?

  JVH

  Basically, because it does not which, according to me, you think it does. As indicated in the documentation for each component is placed in a cluster. This cluster is always an element, and the cluster is placed in a table. Because each element of an array must be of the same data type, this means that each entry this function must be of the same type to the data type of cluster is the same. In other words, you can not, for example wire an integer first entry and a string to the second entry, because this would create a cluster of an integer and a cluster of a rope, which are two different data types, and cannot be placed in a table at the same time.

• [BUG] TestStand 2013 receives corrupt data to LabVIEW adapter if the cluster contains waveform array

  Hi all

  I am having trouble with the corruption of the data. My minimal test case is below.

  I have a VI that returns an array of clusters. My TestStand sequence simply call this VI and connects to its output:

  

  When I run the (with my open VI) .seq file, I can see the update of the Panel before LabVIEW with expected values:

  

  However, TestStand receives all these values. Waveform bays have the correct values, but everything else is empty / null:

  

  If I delete my typedef waveform table, all elements of the cluster are correctly registered by TestStand.

  I've attached an example of test (2013 TestStand, LabVIEW 2013) case.

  Any ideas on how to make it work?

  Hey JKSH,

  Thanks for the detailed on this report. I looked into it a little bit last week.

  I think that it is closely related to the 206892 of CAR, which describes a problem where data will not appear on the report unless a property or variable is specified for the output waveform parameter. However, this does not completely cover your case, because you see incorrect digital data in the row with the waveform of your cluster. I filed 462209 CAR for that matter, and we will investigate it more thoroughly.

  This problem only affects data that appears "below" the waveform in the cluster. In the case of the sample, if you put the waveform as the last element of the bunch, I think that it works correctly. I know that your real data could be more complex than this example, but this workaround solution would help in the meantime? You could also consider separating the waveform of the rest of the data, that would probably work too.

  As I said, please let us know, and it is classified in our system now for a developer to investigate the matter. Please let me know if solutions are not appropriate for your application, we would be happy to know a little more about your overall use case order to work around the problem.

• Initialize the cluster with data types different (lots of data)

  Hello

  I have data, which are composed of different data types. First of all, I have initialize cluster with these types of data and then "print" to light (photo). In case of photo data carries 8 characters than ja 4 floats. It was easy to initialize, but here's the question: How can I do this even if I have data that look like this (interpreter):

  floating point number

  name char [32]

  Short value [16]

  What I create loooong cluster which have a fleet of 32 characters, 16 short films? Or I can create these 'paintings' in a different way?

  THX once again

  -Aa-

  I suggest using the table-cluster and configuration of the cluster size to match the size of your berries, then package these groups together.  In terms of storage of LabVIEW, there is no difference between a group of

  floating point number

  Name1 tank

  name2 tank

  ...

  short value1

  short value2

  ...

  and a bunch of

  floating point number

  -> cluster shipped from

  Name1 tank

  name2 tank

  ...

  -> cluster shipped from

  short value1

  short value2

  So you can use the cluster table to get the right sizes rather than individually create all these values in a single giant cluster.

• Writing only to certain parts of the cluster in an array by reference

  Hello

  I have an array of clusters that I use as well to view and enter data, i.e. elements of the cluster are unmodifiable (disabled) controls used as indicators of "false" (numeric values, strings, LEDs) and some are normal witnesses (numerical values, buttons).

  The "indicator" part of this cluster table must be constantly updated (for example with the positions of the engines), normally by replacing the elements according to cluster in a loop and writing in the table. This can lead to conditions of race with the part 'control': If the user enters data in a 'bad' timing control, it gets immediately replaced by the old value - in this case the update process began just before the user input and completed just after the entrance of (which may be a simple click is enough) , so the old values of controls are rewritten on user controls, as the table should be rewritten as a whole.

  Now, I'm looking for a solution to this critical race condition without changing this 'mixed' approach of control/indicator (e.g. by control and indicator tables separated next to each other and paired scrolling or so - which would make it much more horrible GUI design, among other disadvantages). I know that it is possible to change the value of an element in the cluster without having to rewrite the entire cluster using the element reference. However, it's more complicated if you have an array of clusters, because you want the cluster to a certain index table and to my knowledge, there is no such property that gives you for example the reference to the item table located in an index of certain (who is a lack of long date in the table of Labview manipulation). If you change the 'value' of an element of the cluster property in a table, it seems to affect the 'last active' element of the array, at least it is correlated with the array element that was clicked on last. Maybe there's a way somehow programmatically set that ' last active ' array element and browse the table in this way (setting the flag "correspondent" elements of the cluster by reference) or maybe someone knows a solution 'Nice' and elegant?

  I hope you understand what I mean

  Thanks in advance!

  To avoid such conditions of race, make sure what you write on the Board in the same place change you and write only the data for the indicators. Practically, this means that if you have an event for the control change value, you must have another case of event in the same structure of update of the indicators (timeout or a user event) and make sure that the indicator event takes the rest of the data of the current value (for example through a terminal or a local variable or the DVR suggested Steve). Similarly, you can use the terminal control to the current value of the control for the indicators rather than depend on the event containing the correct value.

• UDP COMMUNICATION FROM ONE SYSTEM TO ANOTHER BY USING THE TYPE CAST

  Dear reader,

  I tried a simple communication udp from one system to the other. I have conditions of that does not change the receiver vi It is set. I'm attaching my vi sending and receiving the part. Please go through it and give me suggestion on how to code the part shipment without changing the receiving party and successffully communicating by udp.

  I am just a starter in LabVIEW.I believe your suggestions of ideas will be very useful to move forward.

  Concerning

  Srinath, R

  One thing you should know is that cast a DBL (or table DBL) requires eight bytes (or an integer multiple of 8).

  The sender must send 8 bytes, which is easier to do by remodeling (padding) of the Boolean array with 8 element (using the table to reshape) prior to cast to a string.

  Here is the code that works. You can easily implement it your original code.

  

• Unpack the cluster data channels

  Hi all

  I tried for this research, it seems quite common, but I don't know that I used the right set of words:

  I receive data from a device in the packages. Each sachet contains several images, each image contains two subframes and each sub-frame contains several data channels. In my vi, the package is a cluster, executives are clusters and the subframes are clusters, all the typedef' ed.

  What I want to do, is to take the big initial cluster and divide the data into a set of tables, one per channel data, without generating spaghetti.

  The function "decimate the table" would work great to do the job, but alas, it only works on the berries, no groups, and it seems that my group cannot be converted to tables.

  Is there something that I am missing? I have attached a photo of high level... Note that I'm not an artist. "N" and "m" values are fixed, so there is no variability

  By "append" do you mean "build the table? ' You can use "Cluster of Array" instead?

  Also note that if you have a cluster where the latter are the same, regardless of how many nested groups there, then you can Cast from Type to an array of this type of final element. For example, if all data real of your cluster is single precision floats, you can the Type Cast to an array of SGL.

  If you can upload a screenshot or your code saved to an earlier version, I will try to provide more specific help.

• Write to the Cluster size in binary files

  I have a group of data, I am writing to you in a file (all different types of numeric values) and some paintings of U8. I write the cluster to the binary file with a size of array prepend, set to false. However, it seems that there are a few additional data included (probably so LabVIEW can unflatten on a cluster). I have proven by dissociation each item and type casting of each, then get the lengths of chain for individual items and summing all. The result is the correct number of bytes. But, if I flattened the cluster for string and get this length, it is largest of 48 bytes and corresponds to the size of the file. Am I correct assuming that LabVIEW is the addition of the additional metadata for unflattening the binary file on a cluster and is it possible to get LabVIEW to not do that?

  Really, I would rather not have to write all the elements of the cluster of 30 individually. Another application is reading this and he expects the data without any extra bytes.

  At this neglected in context-sensitive help:

  Tables and chains in types of hierarchical data such as clusters always include information on the size.

  Well, it's a pain.

• set items in the cluster of typedef double tables

  Hello

  I have a cluster of type def. This group includes 16 double tables, the size of the arrays are identical, but can change during execution.

  I would like to write data from table to this cluster in a loop, where I get the berries during the iterations of a PDM file. If the loop will iterate 16 times and every time I should put something in the cluster preceding the recent read double table.

  What would be the easiest solution here, since I can't use the 'Cluster to table' here and cluster table saw... ?

  Thank you!

  I don't know if it's necessarily easier, but if you change the typedef cluster so that it instead contains 16 clusters and each cluster contains a single element which is a 1 d array, then you will be able to use the Cluster to table and table to the Cluster, although you'll have to do an additional unbundling/package inside the loop for.

• How to get a number of participants of type cast

  Refer to TCPIP given simple client.vi using examples of Labview. I try to get data digital display after the type cast but cannot connect to the service. I tried to use unbundle, cannot work.

  I typed the string connection hoping to see some digital data in it, but I see something like '@'.

  I expect a server.vi of simple data conversions, how to display numbers in the display of digital data without going through the waveform table?

  Thanks in advance

  

  You have typecasted your string in an array of double (or single, I can't tell from the picture of the chart), but try to connect to a scalar indicator.  You must either use a table or Index table indicator for one particular item out of the array to send the digital scalar indicator.

  Regarding your '@', I don't know who.  It all depends on what data the other end of your TCP/IP sends communications.  Put some sensors on the channel, as well as the number coming out casting bytes.

• Node property of a control inside the cluster within a table

  I created a control that has a cluster to a Boolean, a string, and a digital.  Then, in my front, I created a table of these custom controls.  I wish I had access to the property of the controls inside the cluster in the table.  That is to say, I want to change the color of the Boolean or blinking, or "disable and gray" text box.  I think I'm on the right track, or maybe I'm on the wrong track.  I joined and example VI (testtray.vi) and control that I use (UUT_Display.ctl).  Please excuse the use of a flat Structure of the sequence, I know it is bad programming practices, but I just wanted to throw something together.

  Any help would be appreciated.

  Kevin

  Items in a table can have different values, BUT each element of the table share the same properties.

  "Blink" is a property when you make one in tha table blink you will all Flash.

  This restriction does not apply to clusters.

  So in theory, you could develop an XControl that has a data type is an array, but the display is actually a cluster that resembles a table. But write an XControl is not a trivial task.
