| Re: [riena-dev] Unbind the modelBinding and rebind to an other attribute |
Florian, there is no API for unbinding. However you should be able to re-bind, i.e.: textRidget.bindToModel(...model1....) // textRidget now bound to model 1 // later: textRidget.bindToModel(...model2...) // // textRidget now bound to model 2 and NOT bound to model1 See attached snippet.
