ARRRGGGGGHHH i got the problem! That should be related how JAVA interprets numbers in
diferent locales.
Using Locale("portuguese(Brazilian)") in CF5, the number #DecimalFormat(14.57)# was
displayed as 14.57. In CFMX, it is displayed as 14,57 (note the coma).
So, in my COM object, when i try to pass the value 0.50, witch means 500g as weight,
it interprets as 50kg, returning a wrong shipping charge. I didnt notice that beuse
the value returned by the COM is used in other expressions to calculate the shipping.
I did a workaround as follow:
=======
.........
<cfobject type="COM" name="tar" class="Tarifa.clsServicoDLL" action="Create">
<cfset CtErro = tar.CalcularTarifa("#attributes.servico#",
"#attributes.cepInicial#", "#attributes.cepFinal#", "#DecimalFormat(pesoKg)#")>
<cfswitch expression="#CtErro#">
<cfcase value="1">
<cfset ValorTarifa = tar.ValorTarifa / 1000> (NOTE THE / 1000)
</cfcase>
</cfswitch>
You gotta love Macromedia.....
BTW, am i the only brazilian in this list? =)
Cheers

Subject: Urgent problem with COM and CFMX
Hi, i used to have a COM object (Tarifa.dll) that connects to a .MDB database to
calculate shipping charges for my e-commerce. Both files were provided by the a the
govern shipping company (i have no idea how to say that in english).
Everything works fine with cf5, but when i migrate to cfmx, i got the following
error:
-------------------------------
Error casting an object of type java.lang.Double to an incompatible type. This
usually indicates a programming error in Java, although it could also mean you have
tried to use a foreign object in a different way than it was designed.
java.lang.Double
--------------------
Since i know nothing about java, i dont know where to start. Code was working
fine, files are registered with regsvr32 and in place. all the attributes where passed
as usually with cf5. My code for the custom tag is:
==========================
<cfset pesoKg = attributes.peso / 1000>
<cfobject type="COM" name="tar" class="Tarifa.clsServicoDLL" action="Create">
<cfset CtErro = tar.CalcularTarifa("#attributes.servico#",
"#attributes.cepInicial#", "#attributes.cepFinal#", pesoKg)>
<cfswitch expression="#CtErro#">
<cfcase value="1">
<cfset ValorTarifa = tar.ValorTarifa>
</cfcase>
</cfswitch>
<!--- zera variaveis --->
<cfset tar="">
<cfset tarSerAd="">
==============================
If i remove all the lines exept the cfobject, it does not show errors. I think
the problem is in the line:
<cfset CtErro = tar.CalcularTarifa("#attributes.servico#",
"#attributes.cepInicial#", "#attributes.cepFinal#", pesoKg)>
I tried to wrap "#pesoKG#" in quotes, no sucess. The only way i can make this
error dissaper is by using the #ToString(pesoKG)#, but this leads me to incorrect
values (very incorrect) returned by the COM object.
If you have some experience, please let me know what kind of error this is and
where should i look for to try to fix it. Should this be code related?
THANK YOU VERY MUCH!
