The checkbox visible property seems to work differently than it used to. Currently it appears that the default value of the visible property works like a mask over the data binded value. For instance if the default value is visible, then the binded value works properly. However, if the default value is invisible, the data binded value has no effect and the checkbox remains invisible. This becomes an issue when you desire the checkbox to be invisible while the mashup is loading and running services to determine whether the checkbox should be visible or not. Am I correct in my understanding on how this works, or am I wrong? We would certainly prefer the original operation where the visible property was the same as the data binded value.
