Reporter: Vincent Landgraf
There is a bug in the handling of {{XMLRPC::XMLWriter::Simple#element(name,
attrs, *children)}}
If happens that the passed children is an {{Array<Array<String>>}} instead of
{{Array<String>}}. The {{children.join("")}} in line 49 fails because of this.
But it should be avoided, that the children contain two arrays.
The Problem ist only in 1.9 Mode and only in jruby.
I use the following monkey patch as a temporary fix:
{code:title=Patch.rb|borderStyle=solid}
class XMLRPC::XMLWriter::Simple
alias_method :unsave_element, :element
def element(name, attrs, *children)
unsave_element(name, attrs, *children.flatten)
end
end
{code}
To repoduce the problem do this:
1. Clone the project from {https://github.com/threez/rack-rpc}
2. Remove the Patch at the top of {rack-rpc/lib/rack/rpc/endpoint/xmlrpc.rb}.
It looks like in the sample above.
3. Run the tests with {bundle && rake}
The Result will look like this:
