[WASTE-list] WERegisterCustomAttribute

[Alfred Van Hoek]

I have in principle no problem using this api

err = WERegisterCustomAttribute(childItem->tagUserID, childItem- 
 >options, sizeof(Boolean), childItem->typeVariant, (WEReference)text);

However, an additional call like:

err = WERegisterCustomAttribute(childItem->tagUserID, childItem- 
 >options, sizeof(SInt32), childItem->typeVariant, (WEReference)text);

will lead to a paramErr:

Exception thrown in function  
WE3_CustomAttributeTable::AddCustomAttribute(unsigned long, unsigned  
long, unsigned long, unsigned long) (WE3_CustomAttributes.cp, line  
32); error code = -50


Note that tagUserID and typeVariant are different. If the first one  
is used or the second one, no exception thrown, but registering two  
attributes does not work.


I do have some problems (given only one customAttribute is  
registered) when it comes to using this attribute. How would this  
attribute be displayed in an rtf file? I would like to know, in case  
my code is doing something wrong.

Any examples available?

Thanks,

Alfred
