[Tapestry-developer] Connected Parameters problem with 'form' direction

[Simon Robins]

Hi,

I have a page with two PropertySelection components on it. The second PS component is wrapped in a conditional which depends on the value of the first PS component.

The problem is that the after the first PS component renders (in the rewind cycle) it write its new value. This is consistent with the documentation. However, this is only part way through the rewind phase and so all later components that depend on this value render incorrectly and Tapestry fires a StalePage exception.

I can't see any way to know which value is correct during rewind as the relevant set method can be called a number of times with different values during both phases.

It seems that a parameter connected with a direction of 'form' should write its value at the end of the entire rewind phase rather than just after its component has finished rendering.

Any help would be appreciated.

Regards,

Simon
