Possible bug in [data ...] tag.

[pro200@iae.nl]

Hi All,

When playing around with the report page I discovered a possible bug
in the tag [data ...].

I was trying to implement inventory tracking by putting the following
code on the report page.

[snip]
[item-list]
[snip]

[tag flag write]inventory[/tag]
[data base="inventory" field="qty" key="[item-code]"
     value="-[item-quantity]" op="-"]
[/item-list]
[tag export inventory][/tag] ---> Just to see the effect in
inventory.asc

[snip]

When using the named attributes with op="increment" or op="decrement"
or
op="-" the value of the qty-field in the inventory table gets set to
the
value in value="-[item-quantity]".

Example:
quantity in inventory table is 15
-[item-quantity] is -3
This will result in a value of -3 for the quantity field in the
inventory table
instead of (15 -3 =) 12.

When I use the old (positional ) tag [data ..] I get the proper result
(12).
This works: [data inventory qty [item-code] -[item-quantity]
increment]

It seems to me that the [data ..] tag does not recognize the 'op='
parameter
because it behaves exactly as if the 'op=' was not specified.
Meaning, the field qty in table inventory will be set to the value in
'value="some value"'.

Has anyone encountered the same problem?

Regards

Ton
