Question

I have a textArea in my main application as:

<s:TextArea id="textAreaLog" visible="false" height="100%" width="100%"/>

I have another mxml file in which I access that textArea as:

import mx.core.FlexGlobals;

and then:

mx.core.FlexGlobals.topLevelApplication.textAreaLog.text = "Testing...\n;"

Above code works fine i.e. the string “Testing…” gets into the textAreaLog. But upon using appendText property of textArea as:

mx.core.FlexGlobals.topLevelApplication.textAreaLog.appendText = "Testing...\n;"

following error arises:

   Error #1037: Cannot assign to a method appendText on spark.components.TextArea.

Same error occurs if I use instead of where,

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

Any idea of how to resolve this problem. I am able to append text via following command which does not seem a good option or is it? Won’t following line of code by inefficient if size of text in the Text Area increases considerably?

mx.core.FlexGlobals.topLevelApplication.textAreaLog.text += "Testing...\n;"

Answer 1

try this:

mx.core.FlexGlobals.topLevelApplication.textAreaLog.appendText("your text");

Good luck,
