Getting incorrect Slack in the Gantt.

[rdonahue6]

So I added a new column 'Slack' in my Gantt table, and then I am trying to check if the slack matches with the MS Project slack. When I use a simple structure, with like no dependencies, the Bryntum slack values match perfectly with the MS Project values. But when I introduce dependencies in the structure, I see the difference in the slack. Am I doing something wrong here? Is there something I need to add or modify in my dependency store?

Here is the Slack column setting I am using -

{
        xtype       : 'slackcolumn',
        renderer : function(value, meta, record){
               return record.getSlack();
        }
}

Yes the slack might be different. We don't have 100% matching behaviour w/ MS Project.

Hi Arcady,

So is this a bug ? or you implemented it in different way and it is design behavior of Bryntum Gantt ?

Thanks,

It's not a bug just a different behaviour. We had few requests on changing this to make it closer to what MS Project has. And we're going to do this one day but no concrete terms so far I'm afraid.
