how to use fireEvent to set selection in icCube - iccube

Question

I have a multiselect filter widget with members of a demension to use it as a filter in my mdx. This works fine by use #{filter) in mdx. As if the filter is per user unique I want to store it in a database and load it if an user logs in. This works fine and getting the filter as a JSON object:
data = [{
"servicenumbers": [{
"name": "[phone]",
"uniquename": "[Inkomend nummer].[Inkomend nummer].[Nummer].&[76]&[2308]"
},
{
"name": "[phone]",
"uniquename": "[Inkomend nummer].[Inkomend nummer].[Nummer].&[76]&[2329]"
},
{
"name": "[phone]",
"uniquename": "[Inkomend nummer].[Inkomend nummer].[Nummer].&[76]&[3670]"
},
{
"name": "[phone]",
"uniquename": "[Inkomend nummer].[Inkomend nummer].[Nummer].&[76]&[2312]"
}]
}]
In my javascriptcode I have a "fireEvent" event to actually set the filter. code:
function consumeEvent( context, event ) {
var $report = context.$report;
var fireEvent = context.fireEvent.bind(context);
...
some code
...
fireEvent('filter',buildEvent(data));
}
function buildEvent(sel)
{
return {
fireMdxByDefault: false,
isGlobalFilter_: true,
classID: viz.event.SetSelectionEvent,
constructor: function w(A,B,z){x.call(this,B,z);this.classID="viz.event.SetSelectionEvent";this.selection=A},
caption: function (){if(this.selection&&this.selection.length>0){return ic3.asMdxSet(this.selection,"name",false,true)}else{return""}},
asMdx: function (){if(this.selection&&this.selection.length>0){return ic3.asMdxSet(this.selection,"uniqueName")}else{return null}},
asFilterInitialSelection: function (){if(this.selection&&this.selection.length>0){return ic3.arrayProps(this.selection,"uniqueName")}else{return""}},
getSelectedItems: function (){return this.selection},
isSelectionEvent: function (){return true},
isGlobalFilter: function (){return this.isGlobalFilter_},
isEmptyEvent: function (){return false},
value: function (){return this.asMdx()},
asSet: function (){return this.asMdx().replace(/^\(/,"{").replace(/\)$/,"}")},
asDefaultValue: function (){return this.asFilterInitialSelection()},
asReportParam: function (){var H={};H.rpe=1;if(this.isEmptyEvent()){H.nil=true}else{var A=this.caption();if(A!==null){H.dft=A}var D=this.value();if(D!==null){H.val=D}var z=this.asMdx();if(z!==null){H.mdx=z}var x=this.asFilterInitialSelection();if(x!==null){H.fis=x}if(this.isSelectionEvent()){var B=this.getSelectedItems();if(B!==null){H.sel=B}}}return H},
selection: sel.servicenumbers
};
}
If I use "filter" in my MDX #{filter} the filter is applied in the query. But if I use it as a "do set Selection" in my filter widget it doesn't apply the selection and nothing is selected.
Does someone have a suggestion how to make this work?
