AIR 18 Beta "Parameter firstLine must be non-null" Error

[seyfx001]

I have an error which is the below from Adobe AIR 18.0.0.96 and 18.0.0.109 on android and ios.

But same project works fine with AIR 17.0.0.144 on android and ios.

Unfortunately i can not send you any reproducible sample file because i encountered this error from a big project and i don't know how can i reproduce the issue.

I hope you can understand the problem from the error screenshot.

thanks.

Hi,

We would surely like to help you.

But we will need some information to begin with. Could you please try to narrow it down to find that which API's in the code are causing this issue. As we don't have any idea about the source code, it will be difficult for us to guess that just on the basis of screenshot.

And also share the following information to us:

1. Which tool you are using Flash Builder or Pro?

2. On which device you are facing this issue?

[seyfx001]

thanks for reply.

1) flash pro cs6

2) air simulator

os: windows 8.1 - 64bit

probably cause of problem is Flash Pro CS6, TLFTextField and AIRSDK 18 integration.

workaround 1 > i removed a TLFTextField object from the stage and problem solved.

workaround 2 > i changed tlf_txt.text = "bla bla" to tlf_txt.htmlText = "bla bla" and problem solved.

This bug still exists in Air 18.  I just tried to use a very simple construct using

<s:RichEditableText width="100%"  height="100%" fontSize="20"  fontFamily="Arial" textFlow="{textflow}"/>

where textflow is created using

	<fx:String id="helpText">The Badge print application allows you to print your badge by either using the bar code (QR Code) that was sent to you in your confirmation email
	</fx:String>

and

private function setItemText(content:String):TextFlow

            {

                var myTextFlow:TextFlow = TextConverter.importToFlow(content, TextConverter.TEXT_FIELD_HTML_FORMAT, _config);

                var ca:TextLayoutFormat = new TextLayoutFormat(myTextFlow.format);

                ca.fontFamily = "Georgia, Times";

                ca.fontSize = 16;

                ca.textIndent = 15;

                ca.paragraphSpaceAfter = 10;

                ca.textAlign = TextAlign.LEFT;

                myTextFlow.format = ca;

                return myTextFlow;

            }

and creationComplete of component:

textflow=setItemText(helpText);
