Magnus Rundberget commented on TAP5-260:
----------------------------------------
i´m experiencing the same issue using tapestry 5.1.0.5 (using firefox 3.0.x)
I have a zone with a grid displaying a list of users. Below the grid (in the
same zone) I have a autocompleter in a form for looking up users by id for
addittion to the grid.
- Adding users works fine. No problem
- but in the grid I hava actionlink for removing users (through an actionlink
that updates the zone)..
that works fine if and only if the autocompleter textfield does not have focus.
So if I click somewhere else to ensure the autocomplete field does not have
focus it works fine, but if the field has focus and i click the delete function
in the grid the above mentioned javascript error kicks in.
There are a couple of other scenarios to lengthy to describe here, but
resulting to the same error. The error does not occur if I ensure the
autocompleter field does not have focus when reloading zone(s).
Conclusion: The issue has not been resolved and should be possible to reproduce
! :-)

>
> I have a textfield with the autocompleter mixin inside a zone. Everything
> works fine until some event updates the zone.
> After that first update i start getting the following javascript error.
> After some digging i found that what is happening is that when the
> autcompleter mixin renders again as the zone is updated it generates a new id
> for it. This id is used to register with the Ajax.Autocompleter javascript
> object. The problem is that the previous render had already registered the
> same Ajax.Autocompleter object listener but for the previous id that doesn't
> id anymore, hence the error.
