Stale link error when attempting to dynamically add/remove components
Hi,
why do I receive the following error:
---------------error msg------------------
You have clicked on a stale link.
Rewind of form EditProfile/form expected allocated id
#9 to be 'selectBranch', but was 'inputGroup'
(requested by component EditProfile/inputGroup).
This is most likely the result of using your browser's
back button, but can also be an application error.
You may continue by returning to the application's
home page.
---------------end error msg------------------
I receive this error when I attempt to dynamically
remove the inputGroup component and replace it with a
forEach component based on certain conditions.
The inputGroup component is a Palette.
Tapestry version 2.4a4
Ideally I would have liked to just disable this
component again depending on certain conditions, but
from the docs that is apparently not possible.
Thanks in advance for any suggestions.
Cheers,
Stav.

Yes I wrap a Palette in one conditional and a forEach
in another conditional.
The conditionals are the complement of each other,
that is only Palette or the forEach will show at a
time.
Both components display as they should when the
condition says they should.
However the error occurs when the forEach is displayed
and an attempt is made to submit the form.
Thanks again.

What do you mean "remove"? Do you mean wrap stuff in a Conditional?
When a form submits, it goes through a rehash of the original render during
which each component that rendered originally renders again (possibly
multiple times, because of Foreach). The rewind must exactly match the
render or you get StaleLink exception.
I suspect you have a checkbox or other control that controls whether you
include the inputGroup component.
Store the updated value in an auxiliary property and don't apply it to the
real property until the form's listener is invoked.
