I’ll try to summarize me experience and suggestions to make columnChooser function from grid.jqueryui.js and ui.multiselect.js working with jquery-1.4.1 and jquery-ui-1.8rc1.
First of all, me previous suggestion to set mopts.dividerLocation to it’s default value was based on the exception inside of _init function of ui.multiselect.js in the lines 47-48:
Only short additional information. Just downloaded jQuery UI 1.8rc2 with jQuery 1.4.2 (from http://blog.jqueryui.com/2010/…..-ui-18rc2/) and tested everything here written one more time. Everything still works exactly as unter jQuery UI 1.8rc1 and jQuery 1.4.2.
