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: xalan-dev@xml.apache.org
ReportedBy: malhotra@weltek.com
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.
Thanks for your help.
