ADF mobile: Is deviceScope supported in ADF mobile taskflow?

Question

Hi,
Jdev 11.1.2.3.0 + mobile extension.
In my taskflow I have a router component which should call different amx pages depending on the device platform.
My router code in the taskflow (simplified):
    <router id="checkPlatform">
      <case id="__11">
        <expression>#{deviceScope.device.platform eq 'iPhone'}</expression>
        <outcome>isPhone</outcome>
      </case>
      <default-outcome>isPhone</default-outcome>
    </router>But I get the an error message in the EL expression like "deviceScope is not supported".
Is deviceScope not supported in taskflows EL or is this a bug in XML validation?
regards
Peter

Hi,
Yes deviceScope is supported in the taskflow. This could be a product defect.
However, another way to achieve the same event is to separate these pages into two different task flows, and then in the constraint content tab of the Features, you create two content entries and then set the constraint to point to different taskflows. Since you would have two sets of pages targeting different platforms, it's easier to use constraint to direct pages to different taskflows based on different form factors.
There is an example of this in the HR sample application - HR sample app is shipped with JDevleoper. To see where HR sample app can be found, please google for ADF Mobile and navigate to the OTN ADF Mobile Landing page. Then follow the link to samples for further instructions.
