ADF UI Shell update
By Chris Muir-Oracle on May 04, 2012
Developers who use the ADF UI Shell (aka Dynamic Tab Shell) will be interested to know it now has support for multi browser tabs. What does multi browser tab support mean?
As separate to the dynamic tab feature provided by the ADF UI Shell, contemporary browsers give the user the ability to open multiple tabs within the browser. Each browser tab can view different URLs allowing the user to browse different websites simultaneously, or even the same website multiple times.
There's effectively two ways you can currently be using the ADF UI Shell, either you're using the version coupled with JDeveloper and selected through the New Page dialog the Dynamic Tab Shell template, or you've downloaded the source code via the ADF UI Shell patterns page.
If you're using the former option, note that the multi browser tab support within the Shell became available in JDeveloper 184.108.40.206.0 (patchset 5). If you want to make use of this support you will need to consider adding the context parameter USE_PAGEFLOW_TAB_TRACKING to your web.xml to turn on the multi browser tab support in the shell. By default the Shell will not turn this on for backwards compatibility reasons.
Alternatively if you're using the ADF UI Shell source code as downloaded via the original pattern web page, you will not only need to configure this new parameter, but you will need to download the source code (via the zip in the link above) and modify your local copy of the template too. For reference the only code change has been to the TabContext.java class.
Note while this will make the ADF UI Shell ready for multi browser tab support, it does not mean your entire application suddenly can support multi browser tabs. You need to have taken special care in determining your application's bean scopes as detailed in one of my old blogs.
