The ExtJS DatePicker doesn't render properly. It only shows a very wide table-type structure (the title bar etc.) but no text/buttons, i.e., there are no dates to pick. It works correctly in FireFox 2, IE 6/7, Opera etc., so I suspect this is a bug with Gran Paradiso. 

Reproducible: Always

Steps to Reproduce:
1. Goto and select 'Examples and Demos' > 'Toolbar and Menus' > 'Toolbar and Menus'
2. Click on 'Button w/ Menus' > 'Choose a Date'

Actual Results:  
A very wide table structure is rendered. The rows (title bar, footer bar, etc) are styled properly, but no text anywhere. No dates, no buttons, nothing.

Expected Results:  
Should display a calendar date picker component.

it regressed between 04 December 2006 (works) and 10 December 2006 (don't work)

is this enough?
Seems likely to be a regression from the reflow branch landing, in that case. A minimized testcase would be nice :). You might also want to look through the dependency list for that bug to see if there are any duplicates.

not-so reduced testcase

this is not so reduced, but it's at least self-contained

the only thing i could reproduce in another way is that table-layout:fixed; has different behaviuor between brach & trunk, in trunk it expands to 100% width, in branch it does not

Here's an additional, reduced example.  I'm an Ext JS core developer, so if you need any assistance, please let me know.

Um, localhost?  ;-)

I went to the firebug shows that there is width set on the table style as on the containing div.

I am skeptical that is valid.

we need a reduced testcase to judge this.

Reduced Testcase

Renders differently only on Firefox (in comparison to IE6-8, Safari, Opera)

I think this is going to behave badly if a table-layout:fixed table has a column with a percentage width, and perhaps other cases as well.  In those cases the GetMinWidth code is designed to return only a minimum, and not a preferred width, which would need to be different.  That said, for the percentage case, we could probably fix it using a similar approach to the one we use for BasicTableLayoutStrategy, but I'm not sure (after a quick glance) if the other cases are things we can ever hit.

It might also be possible to do something that returns fixed widths when possible and otherwise returns nscoord_MAX.

But I don't think we want to do what this patch does.
