If we can update the model object and changes its value without problem.
Shouldn't we also be able to assign a new model?
onBeforeRender() {
...
this.setDefaultModel(new ReadonlyStaticModel("state1"));
}
onAfterRender() {
this.setDefaultModel(new ReadonlyStaticModel("state2-reset"));
}
I guess I could use the backing model object as opposed to the model to change
the state.
... Changed to:
onBeforeRender() {
...
getDefaultModel().set("state1"));
}
onAfterRender() {
getDefaultModel().set("state2"));
}
