Inserting consecutive character runs with different character properties using Apache

[pingale]

I am writing a microsoft office file using Apache POI-HWPF api (3.8.0) and I am facing one problem to insert two/more consecutive character runs with different character properties.
When inserting two consecutive character runs with different properties first character run properties are override by second character run properties.

Thanks in advanced.

Two shots to move this to the correct forum...:)

What sort of office file?
Word presumably?

Also do you have the code that does this?

I will note that the Word stuff in POI is not production code.
It's been untouched for a while now, and never left the sandbox.
