[jira] Updated: (XALANJ-2127) Add support to dynamicly invoke methods if required.
[ http://issues.apache.org/jira/browse/XALANJ-2127?page=all ]
Brian Minchau updated XALANJ-2127:
----------------------------------
Environment:
Description:
In some cases functions needs to be reolved dynamicly. This functionality was introduced on 2/23/2004 (on org.apache.xalan.xsltc.compiler.FunctionCall revision 1.38) but removed after the release of 2.6. I know there was a problem with it in certain cases, but if you changed the code in the patch in typeCheckExternal(SymbolTable stable) to :
else if(firstArgType instanceof ReferenceType){
hasThisArgument = true;
_thisArgument = (Expression) _arguments.elementAt(0);
_arguments.remove(0); nArgs--;
resolveDynamic = true;
typeCheckArgs(stable);
return _type = Type.String
}
The dynamic calling seems to work in 'more' cases ...
The commit comments of the revert of this patch (revision 1.39) states 'Reverting latest patch by Arun. There are some problems with the new code to invoke functions dynamically (e.g. docbook reports a compile-time type check error). The approach taken to determine when to invoke methods dynamically needs to be revisted.'
Can someone help me with what the exact problems are with 'The approach taken to determine when to invoke methods dynamically needs to be revisted.'.
I'm willing to free some time to fix this problem, but I need some extra information because I don't understand what is wrong the riginal check if dynamic invoction of the method is required.

fix-priority: fp3
I checked, xsl:variable or xsl:param made no difference. Setting to fp3, per the JIRA meeting on June 7, 2005.
