You should be able to set the selections array of the record or records that you want selected.  I'm on my phone now, but if you need an example... Just let me know.

Hmmm... That has worked for me in the past without any problems... I'll try to get you an example when I get back to a computer.

Mauro, how did you set it to []? With gridSelections = []? Or with this.set('gridSelections', [])?

What if you use "this.gridSelections.length = 0" or "this.gridSelections.splice(0, this.gridSelections.length)" to actually clear the existing array rather than creating a new array entirely?

Perhaps it would help if you could share some of the code you're dealing with? Maybe mock up a simple example that reproduces the problem, then we can try to pick out any issues?

Sorry about the delayed response... I was out of town over a long weekend.

Without examples its difficult, but I have some common pitfall ideas.  Are you using name binding on the grid?  To get the selection binding you should have a named grid so that glujs will bind the selections to the name of the grid + selections.  For example...

view: 

{xtype: 'grid', name: 'myGrid'}

viewmodel:

{myGrid: {mtype: 'store'....}, myGridSelections: []}

The name binding will bind to the store and the selections if they are defined in the viewmodel.  In this case changing the myGridSelections through the set in the viewmodel ( this.set('myGridSelections', []) ) should work to clear the grid selections. 

This has worked for me in the past, so let me know if it doesn't.  If you do have a named grid though... then I'll have to see an example in order to help any further :(.  Sorry...

This is one of the best and worst realizations I come to on a regular basis. I so very badly want to blame someone else at all times, but then I realize it's usually my own problem that I have to take care of... *sigh*

It might be helpful if you can describe your solution here once you find it, just in case someone else sees the same behavior. Good luck!
