[reportlab-users] frame question

[Michael Jugovich]

Hi,

I am new to ReportLab and having difficulty using split with a paragraph
flowable. I want to split the paragraph and have it flow into the same frame
onto the next page. Currently the split paragraph simply flows into the next
available frame. I have tried things such as catching the wrap and to check
available height/width then split, splitting on the paragraph, splitting on
the frame, etc. But I have not had any success. Could someone help me out or
point me to some good documentation/code examples for splitting.

Attached is the source for the script. Below is the function that deals with
the splitting.

Thanks for the help!
