Hi, I am getting the following stack overflow error "every" time I access xwiki. I am using xwiki 1.0. Can anyone please tell me what can be the reason. { 02:37:30,538 WARN P1-17 http://localhost:8080/xwiki/bin/view/Main/WebSearch RegexTokenFilter:filter:99 - <span class="error">Error</span>: com.xpn.xwiki.render.filter.XWikiListFilter@ada795: java.lang.StackOverflowError java.lang.StackOverflowError at java.util.regex.Pattern$BitClass.match(Pattern.java:2873) at java.util.regex.Pattern$Curly.match0(Pattern.java:4218) at java.util.regex.Pattern$Curly.match(Pattern.java:4202) at java.util.regex.Pattern$GroupTail.match(Pattern.java:4634) at java.util.regex.Pattern$Curly.match0(Pattern.java:4240) at java.util.regex.Pattern$Curly.match(Pattern.java:4202) at java.util.regex.Pattern$GroupHead.match(Pattern.java:4575) } Thanks Roopesh
