http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4461 Why is int converted to Integer - select="java:size($List)"? Summary: Why is int converted to Integer - select="java:size($List)"? Product: XalanJ2 Version: 2.2.x Platform: PC OS/Version: Windows NT/2K Status: UNCONFIRMED Severity: Major Priority: Other Component: org.apache.xalan.extensions AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] It appears that <xsl:variable name="NumberOfColumns" select="java:size($ColumnList)"/> makes NumberOfColumns of type Integer instead of int. It is causing the exception per the following output: file:///C:/JBuilder4/myprojects/xsltest/testXslTransform.xsl; Line 14; Column 17; Got here A file:///C:/JBuilder4/myprojects/xsltest/testXslTransform.xsl; Line 15; Column 17; 3 file:///C:/JBuilder4/myprojects/xsltest/testXslTransform.xsl; Line 25; Column 16; Got here B file:///C:/JBuilder4/myprojects/xsltest/testXslTransform.xsl; Line 26; Column 16; 3 file:///C:/JBuilder4/myprojects/xsltest/testXslTransform.xsl; Line 30; Column 50; javax.xml.transform.TransformerException: Can not convert #UNKNOWN (java.lang.Integer) to a number ----------------------------------- I am copying the Java code, XSL code and the input file. If I hardcode the value of NumberOfColumns, instead of getting it fron java.util.ArrayList.size(), the code works fine.
