Abstract

A system for creating a custom field type comprises an input interface, a processor, and an output interface. The input interface is configured to receive an indication to create a custom field type. The processor is configured to validate a parameter of the custom field type. The output interface is configured to provide the custom field type for creating a custom field of a custom object.

What is claimed is: 
     
         1 . (canceled) 
     
     
         2 . A system for creating a custom field type, comprising:
 an input interface configured to:
 receive an indication to create a custom field type; 
   a processor configured to:
 validate a parameter of the custom field type, wherein the custom field type comprises a decimal type; and 
   an output interface configured to:
 provide the custom field type for creating a custom field of a custom object. 
   
     
     
         3 . The system of  claim 2 , wherein the output interface is further configured to provide one or more available kinds of the custom field type. 
     
     
         4 . The system of  claim 2 , wherein the input interface is further configured to receive an indication of a selected kind of one or more available kinds of the custom field type. 
     
     
         5 . The system of  claim 2 , wherein:
 the input interface is further configured to receive an indication of a selected kind of one or more available kinds of the custom field type;   the output interface is further configured to provide a form based at least in part on the selected kind; and   the form prompts for parameters of the custom field type.   
     
     
         6 . The system of  claim 2 , wherein the input interface is further configured to receive the parameter of the custom field type. 
     
     
         7 . The system of  claim 2 , wherein the parameter is one of a plurality of parameters. 
     
     
         8 . The system of  claim 2 , wherein the parameter of the custom field type further comprises a field name. 
     
     
         9 . The system of  claim 2 , wherein the parameter of the custom field type further comprises a web service alias. 
     
     
         10 . The system of  claim 2 , wherein the custom field type further comprises a currency type. 
     
     
         11 . The system of  claim 2 , wherein:
 the custom field type further comprises a currency type; and   the parameter of the currency type comprises one of the following: a minimum value, a maximum value, or a precision.   
     
     
         12 . The system of  claim 2 , wherein the parameter of the decimal type comprises one of the following: a minimum value, a maximum value, or a precision. 
     
     
         13 . The system of  claim 2 , wherein the custom field type further comprises an integer type. 
     
     
         14 . The system of  claim 2 , wherein:
 the custom field type further comprises an integer type; and   the parameter of the integer type comprises one of the following: a minimum value or a maximum value.   
     
     
         15 . The system of  claim 2 , wherein the custom field type further comprises a text type. 
     
     
         16 . The system of  claim 2 , wherein:
 the custom field type further comprises a text type; and   the parameter of the text type comprises a maximum length.   
     
     
         17 . The system of  claim 2 , wherein the custom field type further comprises a list type. 
     
     
         18 . The system of  claim 2 , wherein:
 the custom field type further comprises a list type; and   the parameter of the list type comprises one or more list values.   
     
     
         19 . The system of  claim 2 , wherein:
 the custom field type further comprises a list type;   the parameter of the list type comprises one or more list values; and   one of the one or more list values comprises a list value name.   
     
     
         20 . The system of  claim 2 , wherein:
 the custom field type further comprises a list type;   the parameter of the list type comprises one or more list values; and   one of the one or more list values comprises a list value web service alias.   
     
     
         21 . A method for creating a custom field type, comprising:
 receiving an indication to create a custom field type;   validating, using a processor, a parameter of the custom field type, wherein the custom field type comprises a decimal type; and   providing the custom field type for creating a custom field of a custom object.   
     
     
         22 . A computer program product for creating a custom field type, the computer program product being embodied in a tangible computer readable storage medium and comprising computer instructions for:
 receiving an indication to create a custom field type;   validating, using a processor, a parameter of the custom field type, wherein the custom field type comprises a decimal type; and   providing the custom field type for creating a custom field of a custom object.
