How to restrict the rich:editor content to 4000 characters

[vi_mahe_ka1]

Hi

I have an problem in using rich:editor,

In my application we are storing the values of the component in oracle database. as oracle DB column accepts only 4000 characters i want to restrict the rich:editor to accept only 4000 characters just like maxlength attribute of the inputText.is any option available?

ValueChangeListener is not suitable as it fires after the change, and it will not restrict in first.

i can go with the CLOB/BLOB, but i want to know any better option available

I am using jsf 2,richfaces 3.3.3, and oracle 9.

for jsf 1.2 and rf 3.3.3 I successfully used for this the standard buildin jsf validators. I think it was <f:validateLength maximum="4000" /> as a child of the rich:editor.

[vi_mahe_ka1]

any other alternative option to restrict, like maxlength which will restrict the user to maximum length instead of validating the input.

all suggestions are welcome.

ok, since the rich:editor in rf3 is a tinymce, you could go on from there:

maybe there is some plugin to prevent userinput beyond a maximum count of characters (including htmltags)

Wonderfull solution. it works fine for me.

Christian you are the best.i have seen many posts of you. but this one really impressed me. Thank you very much.

here is what i did for those who refering the solution

use following code

<rich:editor onsetup="setup(this);" />

function setup(ed){
ed.onKeyUp.add(
function (ed, evt) {
document.getElementById('deslen').value = tinyMCE.activeEditor.getContent().length;
if(tinyMCE.activeEditor.getContent().length > 4000){
  tinyMCE.activeEditor.setContent(tinyMCE.activeEditor.getContent().substring(0,4000));
  }
}
);
};

it shows the number of characters entered in the editor. as well it sets first 4000 characters to the editor.
