To use curly bracers you will need to setup a var in the
action script:
<mx:Script>
<![CDATA[
[Bindable]
public var query:String="{'11'.EX.'1'}";
]]>
</mx:Script>
So the HTTPService call to QuickBase would look something
like this:
<mx:HTTPService id="srvComment"
url="https://www.quickbase.com/db/bcunhqa6u">
<mx:request>
<a>API_DoQuery</a>
<query>{query}</query> <!-- {'7'.EX.'Fred'}
-->
<clist>6.7.8.9.11.12.1</clist>
<slist>1</slist>
<fmt>flat</fmt>
<options>sortorder-D</options>
<username>{user.text}</username>
<password>{pwd.text}</password>
</mx:request>
</mx:HTTPService>
Also, in case people don't know the QuickBase API is here:
QuickBase
APIThe API also shows well formed querys.
