> NPE in GetAsStringTag when using ignore flag
> --------------------------------------------
>
> Key: TILES-305
> URL: https://issues.apache.org/struts/browse/TILES-305
> Project: Tiles
> Issue Type: Bug
> Components: tiles-jsp (jsp support)
> Affects Versions: 2.1.0
> Reporter: Oleg Gorobets
>
> Current implementation of GetAsStringTag throws NPE if there is no such
> attribute and ignore flag is set to true. GetAsStringTag implies not-null
> attribute while InsertAttributeTag from which it is derived misses check of
> ignore flag before rendering. Need to add simple check in
> InsertAttributeTag.render() like it was in tiles-2.0.5:
> if (attr == null && ignore) {
> return;
> }
