How to create a dependant dropdown list in JHeadStart

I have created a JDeveloper application using JHeadStart. I have created a dropdown list that should be dependant on another value in the table.
So far I have done the following:
1. Created a new view object in the data model.
2. Created a bind variable to supply the value to the where clause for the view.
3. Altered the where clause in the view to use the bind variable.
4. Created a new domain in JHeadStart using this new view.
Where I am having problems is how to assign the bind variable the value of another field in the currently displayed form. The current form is in form layout mode.
I have done this when using table layout mode by doing the following: bindvariable=#{row.field} which works great. The problem is how do I do this in form layout?

Please ask this in the JHeadstart forum

  • How to implement two dependent dropdown lists in an input  table row?

    Hi all,
    I am new in Jdev 11g. I try to develop an input table with two dependent dropdown list. I can create independent dropdown list in such table. When I try to implement dependent one following some examples do it in a form using bind variable in the view object I get an empty listbox. How can I do this? Is it possible. I cannot find any documents about this.
    Thanks in advance

    Hi,
    it hasn't changed between 10.1.3 and 11. The basic outline of how you do it is
    - use a managed bean to query the data
    - populate the list with f:selectItems that point to the managed bean ArrayList<SelectItem> for the master and the detail
    - obtain the master ID in the managed bean by parsing the #{row} variable when the table renders
    - then bulild the detail list
    - have the detail list referencing the ArrayList<SelectItem> you expose for the details
    Note that without proper caching, the action is quite expensive

  • How to create a JSP dropdown list in the latest Early release

    Hello:
    this is probably an easy question. I am trying to create a dropdown list in a JSP form from a data control like "employee id". just dragging the data control attribute does not seem to have any effect in showing the drop down list when the JSP page is run.
    What is the missing factor?
    Thanks in advance for the help.

  • Dependent Dropdown List Help

    I created a dependent dropdown list form in Acrobat X Pro using the example in the tutorial:
    http://acrobatusers.com/tutorials/js_list_combo_livecycle
    This code works great, however, this tutorial only works if the options for the dropdwon lists are full words. Multiple words separated by spaces can't be used because the options for the main list are used as arrays. In this tutorial for example, the options for the main list are: Chassis, Clutch, etc. (one word). This technique won't work is for example, if the options for this list are 'Cylinder Ring', 'Brake Pads', etc.
    Any ideas on how to implement the dependent dropdow lists using multi-word options?
    Thank you.

    Just put quotes around any object properties. For example:
    var oAssemblyParts = {
        "Chasis": [
            ["-","None"],
            ["Rear Bracket",205.95],
            ["Front Bearing",48.95]
        "Cylinder Ring": [
            ["-","None"],
    // etc.

  • How to make one-option dropdown list partial trigger?

    There are two dependent dropdown lists. when list one is selected, the other one will get the SelectItems according the value of list one. My question is: when there is only one selectiem in list one (and the hint 'Please select one..."), how to make it partial trigger in the second time? e.g. I first login and select the ONLY one choice in List one, and the List two gets the values. but the data in datasource updated, so I want to choose the List one again, and make the List two get the new values.

    Hi,
    create a JSF binding (Bindings property on the list component) to a managed bean. The in the code that would trigger the PPR, call
    AdfFacesContext.getCurrentInstance().addPartialtarget(theListBindingName);
    If you have a refresh button, then you could use declarative PPR

  • How to create a group mailing list in JavaMail?

    Hello,
    I've been searching through the entire API, specifically the InternetAddress class and I can't seem to find out how to create a group/mailing list. Does anyone know how to do this?
    That is, I would like to be able to group a bunch of e-mail addresses together and give that group a name "my friends". Then send it off using this 'group mail address' as opposed to an array of InternetAddress[]. Then when the recipients receive the e-mail, they see "my friends" in the To: field, instead of everyone's e-mail address...
    Is this possible in JavaMail? I've tried many things like creating an InternetAddress object passing in a comma-delimited list of e-mail addresses but it doesn't like it.
    Thanks in advance!

    Hi:
    I have the same problem. I've read JavaMail implements RFC 822 which allow mailing lists. But, �how can I implement it with JavaMail?
    Best regards,

  • How to create GOS view attachment list in ECC6

    Hi,
    I created Z transaction. I have to create View attachment List to this transaction. How to create GOS view attachment list in ECC6. can anybody send sample code on this.
    Thanks in advance.
    Zakir.

    Hi all,
    I've following problem with class CL_GOS_ATTACHMENTS.
    Transaction IE01/02/03 (create/change/display equipment) starts and instantiate GOS manager, and related BAdI are called.
    Then, when I choose one of available service, CL_GOS_ATTACHMENTS is instantiated, and inside that class a new GOS manager is instantiated, inspite of already existing instance.
    As a result, related BAdI are called twice, but unfortunately second time some SY variables are not correctly filled, particularly SY-TCODE and SY-MODNO are both empty.
    I've develop a workaround so that when sy-tcode is filled I save it somwhere, and when it's empty I filled it from saved value, does anyone know any other solution??
    Many thanks
