In some cases boolean names start with is.

boolean isSomething;

public boolean isSomething() {
return isSomething;
}

public void setSomething(boolean isSomething) {
this.isSomething = isSomething;
}

Normally Ebean expects boolean fields to not start with "is" and would expect the field name to actually be "something" rather than "isSomething".

You can get a No Such Method error with Ebean trying to find a "setIsSomething()" method which does not exist.
