ID 62987 - Tab ordering in Katana is unexpected

Problem summary

When clicking into a field in the Parameters tab, pressing the tab key should move the focus to the next key. This does not always happen in the order the user expects (top to bottom and left to right), but will rather sometimes skip fields and go through them in an unexpected order, or go to a different tab for a few key presses and then come back to the Parameters tab.

Steps to reproduce

1. Launch Katana.

2. Add a PrimitiveCreate node and connect an AttributeSet node below it.

3. Edit the AttributeSet node's parameters.

4. Drag the primitive’s bound attribute from the Attributes tab to the ‘Drop Attributes Here’ zone in the AttributeSet’s parameters.

5. Click the first entry field in the created numberValue array parameter.

6. Repeatedly hit tab, watching where the focus goes (it will disappear from the Parameters tab and reappear after several key presses).

7. Result: The focus does not go from top to bottom as expected. In some cases the focus seems to jump to a different tab before it comes back to the parameter fields.

Reproduced by support

Katana 2.5v1, 2.5v5 Windows 7

Expected behaviour

When pressing the tab key on a parameter field, the focus should jump from one field to another from the top to the bottom of the tab (and left to right in the case of an array).

Actual behaviour

For the parameters of some nodes the focus jumps between fields unexpectedly and may jump to a different tab inbetween parameter fields.
