Hi all. Sorry to bother you again with this point, but I still does not understand everything...
I tried to define a new type, called "float colored": it is a float, colored with min value as 0, max as 0, mid as 5 I want to add 2 values to my data: -2 * (ch(1) / ch(2)) -3 * (ch(1) / ch(2)) (Probably stupid for the analysis, but I just want to check the functionality) So, I tried the JEP extra value calculator, specifying float coloured as a data type, and 2 * (ch(1) / ch(2)) as the expression. Then, I give a look to the data, and it works: the numbers are preceded with a little coloured square, the colour depends on the value. Great, indeed. So, I tried a second run, this time with 3 * (ch(1) / ch(2)) as expression. It got the following error message: "The bioassay set already has extra values of the type: Extra value type[id=2824; name=float colored]" This sounds very strange to me: If "float colored" is an "Extra Value Type", (this sounds to me as some data type, it's not right ?) why should it be applied ONLY one time ? -------------------------------------------- Something else, which is probably a bug. When I go to Administrate/Types/Extra value types, I click on any extra type declared (for instance for editing the type), I get the following: Base version 2.1 (build #2847; schema #20) Web server Apache Tomcat/5.5.20 Database Dialect org.hibernate.dialect.PostgreSQLDialect JDBC Driver org.postgresql.Driver (version 8.1) Java runtime Java(TM) 2 Runtime Environment, Standard Edition (1.5.0_06-b05), Sun Microsystems Inc. <http://java.sun.com/> Operating system Linux i386 2.6.16-2-em64t-p4-smp Memory Total: 155.3 MB Free: 30.9 MB Max: 986.1 MB Browser Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.8.1) Gecko/20061010 Firefox/2.0 Error message /usr/local/apache-tomcat-5.5.20/work/Catalina/localhost/base2/org/apache/jsp/admin/extravaluetypes/view_005fextravaluetype_jsp.java (Permission denied) Stack trace ...at java.io.FileOutputStream.open(Native Method) ...at java.io.FileOutputStream.(Unknown Source) ...at java.io.FileOutputStream.(Unknown Source) ...at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:140) ...at org.apache.jasper.compiler.Compiler.compile(Compiler.java:295) ...at org.apache.jasper.compiler.Compiler.compile(Compiler.java:276) ...at org.apache.jasper.compiler.Compiler.compile(Compiler.java:264) ...at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:563) ...at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:305) ...at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) ...at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) ...at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) ...at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) ...at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) ...at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) ...at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463) ...at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398) ...at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) ...at org.apache.jasper.runtime.PageContextImpl.doForward(PageContextImpl.java:688) ...at org.apache.jasper.runtime.PageContextImpl.forward(PageContextImpl.java:658) ...at org.apache.jsp.admin.extravaluetypes.index_jsp._jspService(index_jsp.java:278) ...at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) ...at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) ...at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:334) ...at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) ...at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) ...at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) ...at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) ...at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) ...at net.sf.basedb.clients.web.servlet.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java:71) ...at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) ...at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) ...at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) ...at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) ...at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) ...at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) ...at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) ...at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) ...at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) ...at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) ...at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) ...at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) ...at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) ...at java.lang.Thread.run(Unknown Source) -- Emmanuel COURCELLE [EMAIL PROTECTED] L.I.P.M.
