Flex Coercion Error Type #1034

Question

I am building a Flex Mobile Application and I keep getting this error:

TypeError: Error #1034: Type Coercion failed: cannot convert mx.collections::ArrayCollection@ba39581 to Array.

It says that the error is occurring here (at the ArrayCollection Part):

<s:List id="invites" x="5" y="295" width="310" change="rowSelected(event)">
        <s:dataProvider>
            <s:ArrayCollection source="{getInvites.lastResult.Invites.EventTitle}"/>
        </s:dataProvider>
    </s:List>

The "getInvites" HTTPService call:

<s:HTTPService id="getInvites" result="getInvitesResult(event)" method="POST" url="http://localhost/invite.php" useProxy="false">
            <s:request xmlns="">
                <method>GET_INVITES</method>
                <userID>{my_id.text}</userID>
            </s:request>
        </s:HTTPService>

I have no idea why this error is occurring and I have been trying to figure it out for 2 hours. Any help is highly appreciated.

Also the "invite.php" file can be accessed, and is working correctly.

Thanks, Jacob

Most likely your remote Service is returning an array at getInvites.lastResult.Invites.EventTitle which is not the same as an ArrayCollection and can't be converted "on the fly".

You can try this:

<s:List id="invites" x="5" y="295" width="310" change="rowSelected(event)">
        <s:dataProvider>
            <s:ArrayCollection source="{new ArrayCollection(getInvites.lastResult.Invites.EventTitle)}"/>
        </s:dataProvider>
    </s:List>

But, honestly I strongly suggest you add a proper result handler to your HTTPService call and process the results in that.
