[Exist-open] Problem with logical XPath expression

[Josiane M. <jom...@ho...>]

Hello List

I am using the Exist Database version 9.0.2 and I had a problem with logical
expressions. This is a little porsion of debug messages.

java.lang.NullPointerException
        at org.exist.dom.NodeSet.getContextNodes(NodeSet.java:464)
        at org.exist.xpath.OpAnd.eval(OpAnd.java:64)
        at org.exist.xpath.PathExpr.eval(PathExpr.java:98)
        at
org.exist.xmldb.LocalXPathQueryService.doQuery(LocalXPathQueryService.java:116)
        at
org.exist.xmldb.LocalXPathQueryService.query(LocalXPathQueryService.java:80)
        at
org.exist.xmldb.LocalXPathQueryService.query(LocalXPathQueryService.java:64)
        at 
br.ufsc.das.cadseg.repositoryAPI.Banco.querySearch(Banco.java:195)
        at TesteBanco.testaSelect(TesteBanco.java:94)
        at TesteBanco.main(TesteBanco.java:76)

The xpath expression that I am using is:
/sequence/cert/subject/public-key/key-value/pub-sig-alg-id='rsa-pkcs1-md5'and
/sequence/cert/tag/simple-tag/type='increment'

I saw in the forum that Fredrik had a same problem and he said that this 
type of
expression only works fine in previous version of exist-9.0.1, but I didn't
found a previous version in the web site.

Could somebody help me?

Thank's for your help.
