Problem with table tree ADF

Hello

I have following scenario.

I have two read only vo (expert mode, not based on the entity) with a link between them. I want to display the data in a tree with checkboxes to parent nodes and child table. When the user selects a check box to the corresponding parent node with child nodes checkboxes should be auto selected.for achieve this I created transient Boolean attributes on two VO on the user interface layer, I use the Valuechangelistner to get the records of the child and the update of the transitional attribute.but, the problem is that the selection does not occur on the UI for the child node check boxes.

Here is the code for updating the transient attributes.

{} public void deptSelected (ValueChangeEvent valueChangeEvent)
Add the code in the event here...
DCBindingContainer bc = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();
Iterator DCIteratorBinding = bc.findIteratorBinding ("DepartmentVOIterator");
Region of DepartmentVORowImpl (DepartmentVORowImpl) = iterator.getCurrentRow ();
RowIterator ri = region.getEmployeesVO ();
String ID = null;
{if (valueChangeEvent.getOldValue ()! = null)}
Check Boolean = (Boolean) valueChangeEvent.getNewValue ();
if(Check==true) {}
region.setisDeptSelected (true);
}
Else if (check == false) {}
region.setisDeptSelected (false);
}
{while (RI.hasNext ())}
EmployeesVORowImpl empRow = ri.next ((EmployeesVORowImpl));
if(Check ==true) {}
empRow.setAttribute ("isEmployeeSelected", true);
}
Else if (check == false) {}
empRow.setAttribute ("isEmployeeSelected", false);
}}

}

}

whenever the parent is checked valueChangeListner to fires and but the changes don't get triggered on the user interface. I suspect that some how the viewlinkaccesor is getting executed and transitional attribute values are lost.

Guidance on the question?

Thank you

Sam.

Sam, your question a bit sounds like something that I did in my last project.  I have a treeTable with two columns with components selectBooleanCheckbox.  Mine has the boxes with render = "false" for the parent nodes, but I see no reason why you couldn't do what you want with the parent nodes.

The key is in the bean support - the value attribute of the boxes should be a map, so you can have individual values for each node.  So, I have:

Map reqServices = new HashMap();
    public void setReqServices(Map reqServices) {
         this.reqServices = reqServices;
     }
     public Map getReqServices() {
         return reqServices;
     }

And on the page, the elements are similar:

            
                
            

Note this node. ConduitePlan is the index of the card, so when you process the card value is true if the checkbox for that conduitePlan has been verified or does not exist in the map or is set to false if the box is unchecked.  It is added to the card when the user first checks the box, it changes to false if the previously checked box is unchecked.  You will probably use a ValueChangeListener to check the child nodes when a parent node is activated.

    Hello


    I have a problem with ADF Tree Table (af:treeTable) that if I add an item to a group under the facet "nodeStamp" he repeats for all levels in the tree even those outside the group.

    Overview:

    -3-master level / retail structure created using ADF business components (display objects 3 connected by 2 show links)

    -ADF Tree Table based on the master-detail

    -Requirement to indicate 3 levels of data in the first column tree

    -Table tree renders correctly showing the values for "node. FullName ',' node. DisplayValue' and ' node. HoursType' respectively in a tree of level 3.

    -When another element is added to the top node in the tree ("node. FullName') for example, some output text ('node. TimeBuildingBlockId'), it is displayed along components side ' node. DisplayValue' and ' node. HoursType' as well.

    Code snippet:

    < af:treeTable value = "#{bindings." Var PerPeopleFVO1.treeModel}' = 'node '.

    selectionListener = "#{bindings." PerPeopleFVO1.treeModel.makeCurrent}.

    rowSelection = "single" id = "tt1" styleClass = "AFStretchWidth."

    horizontalGridVisible = "true" verticalGridVisible = "true".

    disableColumnReordering = 'true' summary =' entered in the time sheet.

    displayRow = "selected" expandAllEnabled = "false".

    contentDelivery = 'immediate' autoHeightRows = '24 '.

    columnStretching = "column: column1 '.

    Any ideas greatly appreciated.

    Hello

    Try to use a blender to distinguish three levels of the tree. You can have three different facets, three different af:group's.

    When you add at one level, it will not repeat in the other classes.

    Please see the excerpt below.

    selectionListener = "#{bindings." RefBusinessUnitView1.treeModel.makeCurrent}.

    rowSelection = "single" id = "t1" >

    facetName ="#{node.hierTypeBinding.viewDefName}">

  • problems with table formatting

    Hi all

    I currently have problems with formatting or to use a table to record the data (well it will be saved in a .csv file, but I'm trying to use the table to get it all properly formatted to the .csv file for ease of reading). It is probably something easy I'm dominant or do not add. If someone with more knowledge of labview (I only worked a few months with her power) could guide me through the process of how to make my idea works, I would be very grateful.

    I've attached the labview file, so you can see what I'm trying to do and how I'm trying to approach it a little more.

    In addition, if you need a little more explanation, just ask.

    Thank you very much!

    At first glance, it seems that you have made more complicated it must be.

    You have a ton of controls and indicators that could be better managed as tables or groups.

    To your immediate problem of writing file, you could just build a digital table and then use the entry in the File.vi worksheet and select a comma as separator.  The step where you are creating the spreadsheet string and then write in the text file is not necessary.

    The problems I have:

    1. the time is not correctly displayed in the graph (allways 02:00:10 instead of the current time)
    2. the data points in the table have a distance of 1 s (x-scale). This is not correct.

  • Problem with table/table and past data capture

    Hi all

    Newbie is back and I have a problem with my program.

    A brief introduction of what I'm trying to do.

    I'll show you a failure to a system event.

    Based on each event, I will need to connect the error description, the tag, the fault start time and duration.

    All the event information will be displayed on the front table and this table will increase when new event occurred.

    For descriptions and tags - this is fixed based on what fault affects, respectively.

    The issue I'm having is to capture time.

    What I have in mind is to use the time to enter the start time and duration also.

    Departure time is not question because once I press boolean = true, it gives the start time.

    For the duration, when I press boolean = false, it wil give the total duration.

    However, I have a problem as follows:

    (1) to capture what a comprehensive data set (for example / / Desc: fault 1, Tag: one, start time: 2008-12-16 11:15:06 duration: 0 00:00:05) and it passed inside the trap fault Table.

    (2) if the same failure has occurred, it will overwrite the latest information. However, I need to keep the display of old and new events.

    Please notify.

    Opinions and suggestions are welcome mosssssst.

    Million thanks in advance.

    Hi Roziela,

    Thanks for the post and I hope that your well today.

    You must add logic to detect the change of the event (no fault to fault) and produce a Boolean result by 'raising' edge.

  • Problems with tables in InDesign CS4

    Recently upgraded to CS4, I had problems with editing features in tables. The problem occurs after working on a table for awhile - where in a first time, I am able to change the color of the outline and weight very well, but then, after a period of time, it becomes buggy and I'm more able to bring additional features line/column, as changes not being not able to set the color of the outline to zero. The part-time work around, I've found is to leave InDesign and re-launch, and then reopen the document, how can I then change the traits of the table - but only for a while until the problem again and I have to repeat the process of exit and restart. I was wondering if anyone else has had a similar problem and could know a fix (or better work around), or if this is a known bug in CS4. I don't remember what is happening with the change table in CS3. Any help is greatly appreciated.

    I am not fond of the tables. Never been able to do the table styles work properly.

    My method to treat stroke selct the cells and use the proxy in the control panel to set the stroke or STROKE I want to edit, and then change the attirbutes. I find sometimes that I need to change the weight, sometimes the type of stroke, or sometimes even both. If you have applied a troke to a cell that is shared with another, then go in the other cell, I find that you must explicitly choose this feature again to change.

  • Problem with tables made in JHeadstart 10.1.3.3.87

    Hello

    We have recently upgraded from 10.1.3.3.52 to 10.1.3.3.87 (using JDev 10.1.3.4.0.4270) Jhs and have encountered a problem with a window using regions. We have containers horizontal region, vertical region containers, containers stacked area and parts of retail group. In these containers/parts tables are rendered not at all. When I compared the two versions of Jhs .jspx pages I noticed the 10.1.3.3.52 version was the following code (which works)

    < rendered af:panelGroup = ' #{(links. " AwardView1Iterator.*currentRowIndexInRange! =-1 * and links. "(AwardView1Iterator.findMode!='true')}" id = "AwardView1DetailGroupsBelow" partialTriggers = "AwardView1Table" >

    and the 10.1.3.3.87 version had the following as code

    < rendered af:panelGroup = ' #{(links. " AwardView1Iterator.*currentRow! = null * and links. "(AwardView1Iterator.findMode!='true')}" id = "AwardView1DetailGroupsBelow" partialTriggers = "AwardView1Table" >

    the problem seems to be in the following line in the horizontalRegionContainer.vm and stackedRegionContainer.vm-

    #JHS_PROP ($subRegion.rendered 'lent')

    as in line 33 of the horizontalRegionContainer.vm - < af:panelGroup #REGION_PARTIAL_TRIGGERS ($subRegion) * #JHS_PROP ('lent' $subRegion.rendered) * id = ' () #REGION_ID ${subRegion.name} PanelGroup "and
    as in line 32 of the stackedRegionContainer.vm - < af:showDetailItem text = "#REGION_TITLE ($subRegion) ' * #JHS_PROP ('lent' $subRegion.rendered) * #JHS_PROP ($' disabled' subRegion.disabled) #REGION_PARTIAL_TRIGGERS ($subRegion) id =" #REGION_ID () ${subRegion.name} tab ">"

  • Problem with tables

    Hi all!

    I was doing a simple practic, it is a random 3D Board and the problem is that I can't properly use the index in real time with random numbers.

    Here you have two VI, the first is simple, it is a 3D picture, but if you want, you can change the rows or columns and you will see the element changing to the same table 3D.

    But in the second is the problem, here's another 3D painting, but it is filled with random numbers, and when filling it finished start more and, instead, I see all the loose of the original 3D array.

    How could I do that the picture of random origin remains until I want to generate the following, and before that I then generates the one that I can get all the digital changig loose control (pages, rows and coulmns)?

    Your VI is run once and then stop. If you want to update you choose index different values then you must encapsulate this part in a while loop with a stop condition.

    When you want to generate a different set of random numbers click the stop button, and then rerun the VI.

    I suggest you only start by reading some tutorials online on LabVIEW programming. They should teach you the basics.

  • According to LOV with table several ADF

    I have a problem like this.

    I have three table:

    1 - country: CountryID (pk), CountryName.

    2 - Province: ProvinceID (pk), %provinceName%%, CountryID (fk).

    3. employee: EmployeeID, EmployeeName, E-mail, ProvinceID (fk).

    Now, I want to insert a new row in the Employee table with form:

    ------------------------------------------------------------------------------------

    EmployeeID:... < inputtext >

    EmployeeName:... < inputtext >

    E-mail:... < inputtext >

    Country: < Combobox with a list of country values >

    Province: < Combobox with a list of Province values >

    ------------------------------------------------------------------------------------

    The thing is when country-> Province choice will show.

    If selected U.S.: Texas, Califolia...

    or selected England: Mancity, Liverpool...

    We insert just ProvinceID in the table Employee CountryID not at all.

    I try to do this created new view of three table object but it does not work.

    Can anyone help, thank you.

    Thanks for the replies.

    Here are my solutions:

    1. in the Employee entity: add new attributes of entity: country (uncheck persist because I don't want to map that sets the column in the table).

    2. in the view object used: Add the entity attributes: country (that was created previously).

    3. in the Province view object: create new bind variable name: CurrentCountry, then create new view criteria (add criteria: select attributes: CountryID to is equal to Bind variable)... This step to: select ProvinceID where CountryID =?

    4 - Open the view of the employee object:

    create attributes Country LOV

    create LOV for ProvinceID (enter the country for the setting to change view accessor).

    Now, I can insert in the Employee table, but the problem is I can't update, delete lines...

    Something wrong here, I think... Any ideas on this problem?

    Thank you!!!

    In short, you want to

    SELECT extractvalue(myxml, '/PurchaseOrder/Reference')
    FROM dab_test;
    

    This difference is that for dab_xml, it has no columns defined for the table, so you are [OBJECT_VALUE | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm#sthref830] as an alias for a column does not exist.

    With dab_test, you have a column that contains the XML, you must use this column instead of OBJECT_VALUE name.

  • Problems with Tables

    Adobe does not recognize my tables when I choose to prepare the forms.  I need to create text boxes in each cell individually and give them different names.  Is there a faster way?  Why it does not recognize my tables?

    How do you get your form?

    Have you looked at the context menu (right click) t 'Create several copies' using Acrobat?

    You can select the number horizontally and vertically. And as you change the size and spacing of the columns and lines.

    Apache OpenOffice.org Writer program can create the context of the form and add the form control elements or fields and then export it to a PDF form with the fields of the form.

    but when I try to use it in a script, I encountered a problem.  Here's the script:

    ---------

    $vcenters = import-Csv.\vcenter.csv

    {foreach ($vcenter to $vcenters)

    to connect-viserver-Server $vcenter.name

    $getview = get-view ServiceInstance

    $perfcounter = get - see ((get-view_serviceinstance).content.perfmanager)

    $statstotal = $perfcounter. HistoricalInterval

    Write-Host $statstotal [0]

    If ($statstotal [0] - notmatch "SamplingPeriod: 300")

    {

    Write-host "this vCenter has an incorrect setting for the sampling period in the statistics to update past - first time interval is not set to 5 minutes -" $vcenter.name

    }

    If ($statstotal [0] - notmatch "length: 86400")

    {

    Write-host "this vCenter boasts an incorrect location in the backup of setting levels - first interval is not set to save 1 night -" $vcenter.name

    }

    If ($statstotal [0] - notmatch "level: 1")

    {

    Write-Host "this vCenter has a statistical level setting incorrect - inverval first is not set at the statistical level 1 -" $vcenter.name

    }

    }

    disconnect-viserver *-confirm: $false

    --------

    $statstotal [0] is back with this value - VMware.Vim.PerfInterval when I use write-host to display, but when I call the value directly, it appears correctly.  Just try to understand what is happening.

    Thank you.  The use of this script to check the statistical details among other things.

    Thank you
