Dynamically changing textbox to multiline

[vinaur]

I am trying to dynamically change a single line textbox to multiline when a user pastes in text containing newline characters.

The problem is that when I do "setAttribute('multiline', true)" the textbox is converted to multiline, but the value in the textbox is lost. Is this a bug or am I missing something?

Thanks for the help
Aurimas

Changing the textbox to multiline is achieved by deleting the HTML input
element and creating a textarea element in its place. There is some
ancient code that might copy the value from one to the other but offhand
I don't even know if it gets a chance to run. Even if it did work you
would probably want to preserve the selection range.

The code I was looking at doesn't run in the case of converting a
textbox to multiline, so you'll have to save the value manually.
