how to add default values when adding custom component to design view?

[Guest]

I have a set of custom components (usually) extending Spark components. But when adding our custom component onto design view, how can I define defult values (in AS3).

For example, s:Button has default label = 'Button' when added to application, or mx:DataGrid has 3 columns predefined, but when using custom components there are no predefined values like this.

I can put this values in constructor, but they are not visible in design time, only runtime.

Any ideas? Thanks

Are you calling super in your constructor?

yes, I am. By the way I've found the solution. Someone might find this usefull.

In design.xml having

<component name="ExtendedTextInput" namespace="mynamespace" category="beta" displayName="ExtendedTextInput"/>

use this

<component name="ExtendedTextInput" namespace="mynamespace" category="beta" displayName="ExtendedTextInput">

        <defaultAttribute name="text" value="ExtendedTextInput"/>

    </component>

so when adding this component to design view, it will have text setted to value ('ExtendedTextInput' in this case).
