Subject RE: [jira] [Commented] (FLEX-33238) Falcon Compile Error when using id attribute with ConstraintRow, ConstraintColumn, AddChild, GradientGlowFilter or GlowFilter
Date Wed, 14 Nov 2012 19:44:02 GMT
I looked into the "This id is not unique" error on <ConstraintRow> and <ConstraintColumn>
last Friday but didn't come up with a fix. The bug is in how "implicit arrays" are handled.
Background:

<Instance>
    <arrayProperty>
        <Instance/>
        <Instance/>
    </arrayProeprty>
</Instance>

it's really shorthand for

<Instance>
    <arrayProperty>
        <Array>
            <Instance/>
            <Instance/>
        <Array>
    </arrayProperty>
</Instance>

and this even applies when arrayProperty is the default property, so that

<Instance>
        <Instance/>
        <Instance/>
</Instance>

is shorthand for

<Instance>
    <arrayProperty>
        <Array>
            <Instance/>
            <Instance/>
        <Array>
    </arrayProperty>
</Instance>

When I create more parser unit test to deal with the various permutations of MXMLPropertyNode
for various property types, including properties of type array, I will work on fixing this.

Basically, the problem is that the <Instance/> tags representing the array elements
are getting processed twice and the second time the id is already in the map.

Michael Schmalle commented on FLEX-33238:
-----------------------------------------

Ok I figured out what is causing this, the AddChild node gets has two MXMLInstanceNode with
different memory locations. So the next step is to figure out why there are two instance nodes.

BTW the check addNodeWithID() comes back with the previously created MXMLInstanceNode.
