Javascript error on entering maxLength to textInput

Question

We have a UIX page with around 1 text input:
<messageTextInput model="${bindings.Notes}"
columns="80"
maximumLength="250"
rows="6" required="yes"
prompt="Notes" id="Notes"/>
We have set maximum length for the text input. When we try to key in maximum characters for this text input except the Notes field,
its working fine. But when we key in maximum characters for the Notes field(with new line character(\n) inbetween) we get the following javascript error,
Line: 2004
Char:1
Error: "Invalid Syntax"
Code:0

Answer 1

We found the problem with the Message Text Input field.
We have removed the maximumLength for the Message Text Input field. We manually take the length of the field (Length of the field included characters, spaces, carriage returns) and check the same against the maximum length specified in the DB. If the length is more than maximum length , an alert is prompted to the user. This is working fine. If the length is less than maximum length, it doesn't shown an alert, but at times an JBO exception was thrown as you said. When we analyzed we found that the JDeveloper calculates the length of the field as,
     Length entered by the user (Our case it is 1197)+
     No of carriage returns (Our case it is 14) = Length which is checked against maximum length specified in the DB (Our case it is 1211)
Since it is greater than 1200, it throws an JBO Exception. If we remove 11 characters, it works fine.
We add the number of carriage returns and total length of the field. If it is more than maximum length, we alert an message.
The above mentioned solution worked fine. But at times if I give a set of lines without carriage returns it throws the java script error.
Can any one please help out. This has become a critical issue in our project
