Hi joseiru
When I look into the DOM in Firebug, I can see a lot of widget ids like this:
FloatingPane_0,FloatingPane_1,FilteringTable_0,Form_0 and so on.
So it seems as if dojo sets the widget's ids automatically by increasing an internal counter for each class.
So you should remove the id from your .jsp source and see what dojo makes off it.
Perhaps that helps.

Path

I rescue this, because I continue having these collisions, I create tabs on demand, in these tabs I show a jsp that includes dojo comboboxes, a filtering table, dropdowndatepickers, and I get an id collision with all of them, because I create different tabs with the same jsp.

Related to this, I have document.form inside these jsp, and I also have problems with the id collision and I do not know how could I control the number of the item form in the document.forms[]

Can anyone give another idea of how to avoid these? It is important for me, and I would appreciate very much all your help.

Thank you!

Avoid using widgetIds by:

1. Using dojoAttachPoints to get element/object references: http://dojotoolkit.org/forum/dojoattachpoint-getting-widgets-instead-nod...

2. Use combinatorial widgetIds in cases where you really need widgetIds: http://dojotoolkit.org/forum/trying-create-menus-my-own-widget

I have a Main.jsp where I have a Tab, In this Tab I have a ContentPane with Tab.jsp

In this Tab.jsp I have several widgets, for example doing the AttachPoint solution:

But when I try to access to the widget in the javascript file:

alert(this.buscarButton);

I get an undefined value.

What could it be the problem.

For the other solution, I do not know how to access the widget in the javascript, could you give an example for this?

Thanks a lot!
