Re: [Xsltforms-support] getInstanceDocument

[Mark S. <m_s...@ma...>]

Hi Alain,

That is great, except that I grabbed the latest version (from trunk/ 
build, revision 223) and tried you modified version of the form  
without success. I am still getting an error raised by var inst1 =  
model.getInstanceDocument('my_data1');

What have I missed?

All the best

Mark
