Tips

Determine the type of transition you are defining:

• With dynamic transitions, you know what effects you want to play, but not which targets they will play on.
• With explicit transitions, you know exactly what happens to each individual target.

Complex transitions may consist of both dynamic and explicit elements.

Tips for dynamic transitions:

• List all possible targets in the parent composite effect.
• By default, all effects play on all specified targets. Use filtering with dynamic transitions to limit the target set.
• Dynamic transitions can be used with a wide variety of state changes.

Tips for explicit transitions:

• Specify targets on the child effects, or on a composite effect when all child effects of the composite effect have the same targets.
• By default, all effects play on all specified targets. For explicit transitions, make sure the targets are correctly set.
• Explicit transitions typically require a different transition for each change to the view state.

Troubleshooting

Troubleshooting a transition effect that does not play:

• Is the effect target being hidden or removed? If so, make sure you add an <mx:RemoveChild> property to the view state definition, or an <mx:SetPropertyAction name="visible"> tag in the transition definition.
• Does the change to the view state define settings that pertain to the transition effect? For example, if you have a Resize effect, you must change the width or height property of the target when the view state changes to trigger the effect.
• Check that you specified the correct targets to the transition.
• Check that your filter settings on the effect and on any parent effect are not excluding the target.

Troubleshooting an effect playing on too many targets:

• Add a filter for a dynamic transition, or change the targets for an explicit transition.

Troubleshooting wrong effect parameters:

• Did you specify explicit parameters on the effect? Are they correct?
• Ensure that you correctly set the showTarget property for mask effects such as the Iris effect, and the wipe effects.

Troubleshooting a flickering or flashing target:

• Ensure that you correctly set the showTarget property for mask effects such as the Iris effect, and the wipe effects.
• Is the effect target being hidden or removed? If so, make sure you add an <mx:RemoveChild> property to the view state definition to remove the target, or an <mx:SetPropertyAction name="visible"> tag in the transition definition to hide the target.

Troubleshooting when an application does not look correct after a transition:

• Some effects leave the target with changed properties. For example, a Fade effect leaves the alpha property of the target at the alphaTo value specified to the effect. If you use the Fade effect on a target that sets alpha property to zero, you must set the alpha property to a nonzero value before the object appears again.
• Try removing one effect at a time from the transition until it no longer leaves your application with the incorrect appearance.
