I am trying to enter a value greater than 100 char "www.abc.def/kll/..." , but parameter -value text box is not accepting more than 100 characters .
Please suggest, if this is a limitation?, Is there any way we can resolve it.
I just had a quick look at the HTML and there's a maxlength=100 attribute specified on the input. You will have to customise it yourself.
I'd suggest you have a look at the following 2 posts as they are similar (though the files that need to be edited are different obviously):
If you want to proceed down the customisation path, let me know and I can probably find which files you need to edit.
