Alex commented on XALANJ-2315:
------------------------------
I have just added a similar bug #2374, which has the code fix. Basically, I
added the conversion for CharSequence directly in the "convert" function.
However, instead of directly modifying the xalan jar file, I placed my own
modified file in the classpath which precedes xalan so that it will be
overriden.
> MethodResolver.convert converts CharSequence into Double

>
> Key: XALANJ-2315
> URL: https://issues.apache.org/jira/browse/XALANJ-2315
> Project: XalanJ2
> Issue Type: Improvement
> Components: Xalan
> Affects Versions: 2.7
> Environment: all
> Reporter: Brian Knorr
> Assigned To: Brian Minchau
>
> When using AggregateTransformer to convert xml results to html the exception
> below is encountered. This is due to the convertedArgs being incorrectly
> converted for the method String.replace(CharSequence,CharSequence). Right
> now MethodResolver.convert only can convert for types String, Object,
> Character, Boolean, and Number. Please add support for CharSequence.
> Thanks,
