First of all, thank you for the response Walter! I tested a bit around with the W3C validator and i have noticed that my plugin page throws almost the same warnings / errors as any other (default) plugin page (or rather the entity selection site). So i have included prototye into one of the default plugins, and that resulted in the same error message when clicking on the object history button.
So i'm now pretty sure that anything of the core architecture of Novell iManager collidates with any functionality of the prototype framework, and the behaviour seems to not depending on the individual functionalities of my plugin. Regarding the source code - i'm not sure if i was able to get the relevant contents of the page as the error only appear when clicking on a button (which opens a popup window, and the error only appear when this windows contains an object with trailing dot, and only when prototype is included...). IE don't allow me to extract the source code of a popup window. I will now try to customize the prototye script as it seems to contain much more functionalitys as i need for my plugin.. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
