Subject [jira] Commented: (BEEHIVE-1005) Don't add a "\n" after the textarea start tag rendering unless there's a leading blank line in a netui:textArea content.

Carlin Rogers commented on BEEHIVE-1005:
----------------------------------------

With the change in BEEHIVE-841, we appended a "\n" after the rendering of the textarea start
tag and before the content. When this is rendered directly into an HTML document in a browser,
the leading
newline is stripped from the value of the textarea. The tests described in the original bug
behave correctly.

However, one noted issue...

With some browser DOM manipulation, when our tag output is inserted into an HTML document
via the innerHTML property, FireFox, however, preserves the newline in the textarea value.
Note that IE strips the newline from the value of the textarea.

I think it would be best to revert back to not appending the "\n" unless the known content
starts with a new line. This would still solve the problem for BEEHIVE-841 as well as solve
the issue noted with the the use of the browser DOM manipulation noted here.

I'll make this change shortly.

>   Components: NetUI

> When the netui:textarea contains blank line(s) in the beginning, the first blank line
always gets removed.
> I will attach a repro app.  
> Repro Description:  Takes input from a text area and outputs it into another text area.
If the first line from the input is a blank line then a carriage return is output after the
textArea rendering and continue on with the text.  The blank line should be included in the
rendered text area.
> Visual description:
> Enter the following into the first textbox: "\nMyText" (where \n is a return or the input
from the datasource)
> Click Submit / Next Action
> Expected output of the second textbox: 
> <textArea>
> MyText</textArea>
> Actual output in the second textbox: 
> <textArea>
> MyText</textArea>
> The reason is the first \n is used as the return after the textArea tag instead of including
the \n at the end of the rendered text area start tag.
