Restrict input length of Tabular Form columns
One problem with Tabular Form Column is that they don't have a "Maximum Width" property as Page Items do. APEX automatically generates a maxlength=2000 for all columns. What is the result? The user gets a

Hello,
I tried to use this hint in my apllication and it doesnt work.
I have installed Apexlib framework and im using it in Tabform page in process updating changed rows.
I would like to limit the lenght of one columnfield in tabform. I Use the hint in Link atribute in updatable report and add reference to apexlib javascript files in page template(I use the 'One Level Tabs' template). When checked code of generated page there are references to apexlib javascript files, but generated javascript, where is atribute adding is missing. I searching for two days but dont know where im wrong. Can you help me identify where the error is?

apexlib is not defined
Maybe that's your problem.
