Sales Pack Sales Order Delivery Button causes Problem

[shalmaxb]

I have a client, who uses the most recent version of sales pack, where there had been introduced a button to the delivery entity. In that place we use already another button from a third party extension, which now is not displayed anymore.
How can we get back our custom button?

When there is the Followed Button, our button is displayed side by side with taht button, but not when it is the delvery button.

An extension should have the module order set to a value grater than 16 (which is the Sales module's order). And use "__APPEND__" when defining a button in clientDefs.

thanks, yuri, I succeded to modify the extension to work correctly aside the delivery button.
