Hi,

field itself does not have any limits, only limit I can think of is database limit of 2048 characters - try changing #__cck_core_fields column defaultvalue to type text (now it is varchar(2048) which imposes this limit). 

As always with such experimental changes - backup before you do anything!

Thanks Klas I'll try it

I tried it but didn't work. I changed the character limit but didn't find where to change the type value. Although I change the character limit to 5000 or more the limit still 2048. I had to make several js code fields to place all the code :(

This should be done directly in the database, character limit means nothing if there is not enough space to store it into database.

Don't forget to backup your database before doing any changes.

I've just hit this issue as well and having multiple Script JS fields on the form didn't work in my case. Is it possible to have the data type updated to TEXT for the defaultvalue column as part of a future release? I will adjust the column datatype manually as a solution for now.

You should make a pull request on a github

Have created a PR here.

thnx
