I can’t remember exactly. It was solved a long time ago. All I can remember is that it was somehow related to instance not having expected binding / ivars values.
My comment where just to give good recommendation on the WOSwitch strategy: it’s working great. But also to warn you that once you make it work in dev, you might still encounter bug in extensive testing, and when you do, keep in mind that it might be related to multiples instances of your component (WOSwitch will have to instantiate one of your switched component). At the time, once I figured out exactly what was the problem, it was not hard to fix, so you should have no problem fixing it either. Sorry, it’s all I remember. jfv > On May 29, 2015, at 6:21 PM, HOUNKPONOU Ronald <[email protected]> > wrote: > > Please Jean-François! > > How to not use it? > I would like to learn good practices. > > > 2015-05-29 23:12 GMT+01:00 Jean-François Veillette > <[email protected] <mailto:[email protected]>>: > WOSwitchComponent? > https://wiki.wocommunity.org/display/documentation/WOSwitchComponent > <https://wiki.wocommunity.org/display/documentation/WOSwitchComponent> > > I used it with great success, once I figured out how to not use it. > Right now I can’t remember what was the symptom, what what the cause and how > I fixed it. > All I remember is that it’s related to sharing instances your component > instantiated by the switch component.
