Hi,
I think I might have found a Class Cast bug where a StringBuilder is
expected but in certain cases a String is returned...It appears that in
org.geotools.filter.text.ecql.ECQL this method:
public static String toCQL( Filter filter ){
FilterToECQL toCQL = new FilterToECQL();
StringBuilder output = (StringBuilder) filter.accept( toCQL, new
StringBuilder() );
return output.toString();
}
is performing a cast to StringBuilder from accept methods for filters.
Almost all FilterVisitors return a String Builder except for the method in
class org.geotools.filter.text.ecql.FilterToECQL
public Object visit(Id filter, Object extraData) {}
this method returns a String causing the case to fail when
org.opengis.filter.Id is the Filter...
I've attached a sample class that causes the issue.
If this is not an issue let me know! If it is, how can I file a bug report?
Thanks!
Andrew
