Hi Cocoon Developers,
I get a ProcessingException: Language Exception
when passing parameters to a logicsheet (cocoon2.0, Tomcat 4.0.1, Win2k,
JDK1.3).
This happens _only_ when passing the parameter
within the content of a custom tag
via
<xxx.customTag>
<xxx:param name="start">0</xxx:param>
</xxx:customTag>
(not as an attribute).
The generated code does not compile:
start = Strings.isDigit(this.characters("0");) ?
--------------------^
Strings.toInt(this.characters("0");) : 0 ;
--------------------^
A transformation of the same xml / xsl with Xalan-J 2.2
(without cocoon) seems to work, but not with Cocoon 2.
Embedding the value with: <xxx:param
name="start"><xsl:expr>0</xsl:expr></xxx:param>
does not solve the problem: then I have different value types for the
same variable (String for an attribute, int for <xxx:param ...>, not
to mention the inconvenience for logicsheet-users.
Does not work either: <xxx:param
name="start"><xsl:expr>"0"</xsl:expr></xxx:param>
then I get "\n0".
Did anybody experience or solve this problem ?
Thanks in advance,
Friedrich Schuster
