    • getAvailableProperties

      public ArrayList<XItemPropertyDesc> getAvailableProperties(Locale locale)
      Description copied from interface: IXItemBasic
      Gets a list of base properties available for this item.

      Note that plugins may extend these properties. Use de.xima.fc.web.common.fd2.XItemPropertiesHelper#getAvailableProperties to get a list of all properties, including properties added by plugins.

      Note: Caching the properties returned by this method is not required. Just create the list of properties and return it.

      Specified by:
      getAvailableProperties in interface IXItemBasic
      Parameters:
      locale - The current locale that can be used for locale dependent properties.
      Returns:
      A list of all base properties available for this item.

    • getIcon

      public String getIcon()
      Specified by:
      getIcon in interface IXItemBasic
      Returns:
      The CSS class for the icon of this form item, such as for example ico-fc-XCheckbox.

    • getPrefix

      public String getPrefix()
      Description copied from interface: IXItemBasic
      Finds the prefix for form items of this type, such as cb for checkboxes or tf for input fields. This prefix is used, for example, in the designer to generate a default name for newly added form items (tf-1, cb-2).
      Specified by:
      getPrefix in interface IXItemBasic
      Returns:
      The prefix for form items of this type.

    • getFieldNameConventions

      public IXItemFieldNameConventions getFieldNameConventions()
      Description copied from interface: IXItemBasic
      Gets the naming conventions for the form fields used by this type of form item. The default assumption is that in the rendered form, only a single form field (such as <input>) exists, with the name as configured in the form designer. The default implementation returns DefaultXItemFieldNameConventions, which is suitable for such form items.

      Some form items may have more complex naming conventions. For example, an upload form item could have a secondary input field for storing the UUID of the upload; and the name of that derived input field could e.g. be the configured name (e.g. upl1) plus some suffix (e.g. upl1.uuid). Other form could have more derived field names with various data, as is the case for e.g. the builtin appointment picker form item with various related field names such app1_date, app1_time, app1_date_time , or app1.typeuuid etc.

      This method must return the field name conventions for such items, so that these conventions can be respected and enforced by formcycle. formcycle must be aware of the naming conventions for various reason, e.g. in order to be able to reject submitted request values when the request value belongs to a form item that is unavailable in a certain state or for certain user groups.

      Specified by:
      getFieldNameConventions in interface IXItemBasic
      Returns:
      The naming conventions for this type of item. A null value is treated as if DefaultXItemFieldNameConventions had been returned.

    • isSubmitsValues

      public boolean isSubmitsValues()
      Description copied from interface: IXItemBasic
      Checks whether form items of this type can send values to the server when the form is submitted. Form items that do not submit values are, for example, not validated and no values are ever stored in the database. Form items such as pictures or charts do no submit values, while classical form elements such as input fields and checkboxes are a prime example of form items that do submit values.
      Specified by:
      isSubmitsValues in interface IXItemBasic
      Returns:
      Whether form element of this type can send values to the server when the form is submitted.

      public IXProcessUploadResult processUpload(IXProcessUploadParams params) throws IOException
      Specified by:
      processUpload in interface IXItemBasic
      Throws:
      IOException

    • renderItem

      public void renderItem(com.hp.gagawa.java.elements.Div container, XItemRenderData renderData, XItemRenderCtx renderCtx, IXFormRenderContext formRenderCtx)
      Description copied from interface: IXItemBasic

      Specified by:
      renderItem in interface IXItemBasic
      Parameters:
      container - The container that will contain this form item in the final form. You should append children to this container.
      renderData - The current render data with the properties and options of the item.
      renderCtx - The current render context giving you access to the global configuration.
