In my current project use a lot of re usable taskflows. In one particular situation I needed exactly the same taskflow to be re-used with one tiny small difference: The displayed query component needed to have different fields compared to page in the base taskflow. Now there are lots of possible solutions (two query components and a switcher, or two query components using the rendered property). I choose a different solution using ternary operator and EL in the page definition. Use case I need to display a different query component when the taskflow is started in a specific mode.

When the but...
