public class DesktopBackingContext
The DesktopBackingContext
is used to interact with the underlying Desktop control. This is the
BackingContext for a Desktop.
This BackingContext
can only be referenced from a backing file. If you need to reference
this from a JSP you should use DesktopPresentationContext
instead.
To get a handle to the BackingContext just call the following:
DesktopBackingContext.getDesktopBackingContext(request);
Note: most methods for retrieving child contexts do not work if called from the init()
method of a backing file. This is because the portal tree has not been fully initialized. You may have to call
the method from the preRender()
or handlePostbackData
method.

public static DesktopBackingContext getDesktopBackingContext(javax.servlet.http.HttpServletRequest request)
Obtain a reference to the current DesktopBackingContext
in the request.
Note: the DesktopBackingContext should only be obtained from a backing file. If you
think you need this context from a JSP look at DesktopPresentationContext.
request
- http servlet request.
public BookBackingContext getBookBackingContext()
public BookBackingContext getBookBackingContextRecursive(String definitionLabel)
getPageBackingContextRecursive()
as that method returns both.
Note: this method may return null if called from the init() method of a backing context.
definitionLabel
- of the book
public BookBackingContext[] getBookBackingContextsByMeta(MetaData[] metaData, int limit)
limit
is reached. Meta
data can be added to books by inserting <netuix:meta> tags into the body of the main book element.
If you are interested in both books AND pages use getPageBackingContextsByMeta()
as that method returns both.
metaData
- contains the search criterialimit
- maximium number of items to return: 0 == no limit, 1 == first match , n == first n matches
public PageBackingContext[] getPageBackingContextsByMeta(MetaData[] metaData, int limit)
limit
is reached. Meta data can be added to pages by inserting
<netuix:meta> tags into the body of the main page element.
metaData
- contains the search criterialimit
- maximium number of items to return: 0 == no limit, 1 == first match , n = first n matches
public PortletBackingContext[] getPortletBackingContextsByMeta(MetaData[] metaData, int limit)
limit
is reached. Meta data can be added to portlets by inserting
<netuix:meta> tags into the body of the main portlet element.
metaData
- contains the search criterialimit
- maximium number of items to return: 0 == no limit, 1 == first match , n = first n matches
public PageBackingContext getPageBackingContextRecursive(String definitionLabel)
definitionLabel
-
public PortletBackingContext getPortletBackingContextRecursive(String instanceLabel)
instanceLabel
- unique instance label of the portlet
public PortletBackingContext[] getPortletsBackingContextRecursive(String definitionLabel)
getPortletBackingContextRecursive(String instanceLabel)
Note: this method may return null if called from the init() method of a backing context.
definitionLabel
- label of the portlet
public HeaderBackingContext getHeaderBackingContextRecursive()
public FooterBackingContext getFooterBackingContextRecursive()
public PageBackingContext getDisplayedPageBackingContext()
Return the last displayed page (not book). This method listens to Page Change events and remembers the last page that was activated in the Desktop. If no page changes have occurred then the first default page found will be returned.
Note: This method will only return the right results if called after the
handlePostbackData
method. Therefore, it is recommended that you call this methods from
preRender
.
PageBackingContext
public String getTitle()
Get the internationalized title for this desktop.
public void setTitle(String title)
Set a temporary value for the title.
public String getDefinitionLabel()
Get definition label as defined in the portal file.
public LookAndFeelDefinitionId getLookAndFeelDefinitionId()
Return the look and feel definition id. This method will only work for streamed portals.
public String getLookAndFeelDefinitionLabel()
Return the look and feel definition label.
public DesktopBackingContext.AsyncModeType getAsyncMode()
DesktopBackingContext.AsyncModeType
public void setAsyncMode(DesktopBackingContext.AsyncModeType asyncMode)
Set the async mode for this request. Depending on the original state
the following will occur:
Original State | New State | Effect |
enabled | disabled | The request will finish out and a redirect will be sent to the browser as a JSON response. The redirect will be a regular post back but with a special parameter informing the server not to perform javascript rewriting of the URLs. The next request will not be an AJAX request as the URLs have not been rewritten. subsequent requests will default back to asyncContent="enabled" |
enabled | compat_9_2 | The AJAX request will finish out and a redirect will be sent to the browser as a JSON response. The redirect will be a regular post back but with a special parameter informing the server to run in compatibility mode (compat_9_2). Under this mode all portlets with the attribute "asyncContent" set as ajax or iframe will perform a separate request. Subsequent requests will default back to asyncContent="enabled" |
disabled | enabled | The full request will finish out as normal, however all links will then be rewritten to perform AJAX request. All requests after that will be of type AJAX. The server will continue to act in AJAX mode until the mode is rest or a link is clicked which has not been rewritten |
disabled | compat_9_2 | The request will behave as in compat_9_2 mode just for that request. Under this mode all portlets with the attribute "asyncContent" set as ajax or iframe will perform a separate request. Subsequent requests will default back to asyncContent="disabled" |
compat_9_2 | enabled | Not Supported |
compat_9_2 | disabled | The request will behave as in disabled mode just for that request. Under this mode all portlets with the attribute "asyncContent" set as ajax or iframe will be ignored. |
