I added this code for adding digits in price unit 


<xpath expr="//field[@name='invoice_line_ids']//field[@name='price_unit']" position="replace">
<field name="price_unit" digits="[12,12]" column_invisible="parent.cover_sheet_count == 0"/>
<field name="price_unit" digits="[12,2]" column_invisible="parent.cover_sheet_count != 0"/>
</xpath>


it is working perfectly in using replace , when coversheet count != 0 the price unit with 12 decimal precision . 

when coversheet count == 0 price unit with 2 decimal precision 


When i use attribute like this 


<xpath expr="//field[@name='invoice_line_ids']//field[@name='price_unit']" position="attributes">
<attribute name="digits">[12,12]</attribute>
<attribute name="column_invisible">parent.cover_sheet_count == 0</attribute>
</xpath>

<xpath expr="//field[@name='invoice_line_ids']//field[@name='price_unit']" position="attributes">
<attribute name="digits">[12,2]</attribute>
<attribute name="column_invisible">parent.cover_sheet_count != 0</attribute>
</xpath>

when coversheet count == 0 price unit with 2 decimal precision  , only one scenario is working , 
coversheet count !=0 case the price unit field is invisible not decimal precision with 12 digits 


What is the reason for this behaviour ??

Your first example is removing the price_unit field and replacing it with two price_unit fields.

Your second example is finding the price_unit field and changing the attributes, then finding the price_unit field again (the same field) and changing the attributes again - so only the second change is actually being made.
