Pattr in bpatcher picking up value from parent on load

    Mar 27 2014 | 5:35 pm
    I'm sorry to add another topic to the already extensive list on the subject of pattr issues, but I'm stuck and couldn't find a solution on the forums despite extensive reading!
    I'm trying to get a bpatcher to pick up the value of a pattr in the main patch on load (in my case a file path required for preset handling) but I'm having trouble. I can successfully bind the pattr in the bpatcher to the pattr in the parent, but on load it outputs a '0' rather than the bound value.
    I'm sure this is a simple problem but I'm getting nowhere with this and wondered if somebody could point me in the right direction?
    I'm attaching a zip file with two .maxpat files: unzip and open bpt_top.maxpat then follow the comments to recreate the problem.
    Thanks in advance for any help
