Element Not Bound error help please

MattJensen — Sat, 11 Dec 2021 14:22:26 GMT

Hello,

I have been trying to combine the "LegendBasic" code with "FeatureLayer - show InfoWindow on mouseOver" code and have come up with what is below. I have a problem in line 96 it says "the prefix 'mx' for element 'mx:TextArea" is not bound, and I am lost in how to solve it.

Thank you 🙂

    <!--
        This sample shows how to use the Legend component to build a legend that displays some or all of the layers in the map.
        To create a new legend component specify the map to be displayed.
        Optionally you can provide a list of layers to display in the legend.
        If no layers are specified then all the layers will display in the legend.

        The respectCurrentMapScale property, if set to true (default) will force the legend component to only display layers that are visible in the current map scale.

PS. Eventually, I am trying to dynamically show the correct legend when a layer is turned on, as well as the correct mouseovers.

Change it like this

<mx:TextArea id="myTextArea" width="250" height="95" />

and delete this

</mx:TextArea>

One more thing, i will clean the solution and then rebuild it...Also, you can delete the line, and rewrite it as i dont see anything wrong with it...
