DEVELOPING COLDFUSION 9 APPLICATIONS
Flex and AIR Integration in ColdFusion
• Ensure that the query column names match the case of the properties in the ActionScript object. Use the
settings in the destination to do so. Set the
property-case
ColdFusion converts all column names to lowercase.
• If you are using an array of structures:
• Create the array to contain the Value Objects, as follows:
<cfset var ret = ArrayNew(1)>
• Loop through the query to create the structure that contains the results of the query, for example:
<cfloop query="qRead">
<cfscript>
stContact = structNew();
stContact["__type__"] = "samples.contact.Contact";
stContact["contactId"] = qRead.contactId;
stContact["firstName"] = qRead.firstName;
stContact["lastName"] = qRead.lastName;
stContact["address"] = qRead.address;
stContact["city"] = qRead.city;
stContact["state"] = qRead.state;
stContact["zip"] = qRead.zip;
stContact["phone"] = qRead.phone;
ArrayAppend(ret, duplicate(stContact));
</cfscript>
</cfloop>
• Use the
structure element to specify that the Value Object CFC is the type, for example:
__type__
stContact["__type_"] = "samples.contact.Contact";
• Use the associative array syntax, for example,
ActionScript property. If you use the other syntax, for example,
makes the key name uppercase.
Managing fills
To determine whether to refresh a fill result after an item is created or updated, you include a

<auto-refresh>true</auto-refresh>
<ordered>false</ordered>
</fill-method>
