really simple two column sticker template

stickertemplate.pt

<!--
THIS version prints TWO stickers side by side. It does this by calling
view.nextItem manually in the tal:define on the <tal:bothstickers> block.

To retrieve the item, use view.current_item, that will return an array like:

    [analysis_request_object, sample_object, sample_partition_object]

Although sample_object (position 1 in the array) will never be None,
analysis_request_object can be None when

    a) The user requested to render stickers for samples (instead of ARs) or
    b) The user requested to render stickers for sample partitions or
    c) The user requested to render stickers for reference samples.
    If c), both analysis_request_object and sample_partition_object will be None
