Re: [qooxdoo-devel] Binding custom list like objects

[Martin W. <mar...@1u...>]

Hello Eric,

now i'll get what you try to achieve.
But i have to say the only way i see is also to add and remove the  
binding every time the record changes. The binding is based on event  
listeners and the missing capability of changing the source of a event  
listener does also apply to the data binding.
But i just have another idea! If the order is not important in the  
arrays, you can bind on the first item of the array and just shift the  
whole array around. That way you can keep the binding. How about that?

Best,
Martin
