[SOLVED]LayoutDialog and editable grid combobox - strange behaviour

[zmaj]

Hello,

ich have a editable grid with 2 comboboxes and a butten that creates a form inside a LayoutDialog(modal) for adding new entries to the grid.
Editing the grid and also creating and submitting the form works fine if i open
one combobox inside the grid when the page is displayed.
But when i klick on the button to add a new entry first (without opening the combobox
inside the grid)and the cancel the LayoutDialog i get a illigal argument error when trying to open
the combobox inside the grid after the dialog is hidden.
Any ideas what causes this strange behaviour ?

Let me mention that it only happens in IE6 but thats where it must work here :-/.

I found the problem. After adding width: to the combobox object config and setting it to the same size as the colums in the columnmodel it works .
