modify js script in stylesheet

[YHLpuyu]

is there any solution that I can modify the script in stylesheet?
I add a FeatureModelLayer and create a script for stylesheet, for render shapefile. In code, I create a array for stores feature.id, which those features I interested, there maybe more than one array, each array has own style. for example: the layer total has 6 features, I choose first 3 features for array A, others for array B. A=[1,2,3], B=[4,5,6], the number is feature.id, and use below function:

function getClass()
{
    if(feature.id in [1,2,3]) return "normalstyle";
    else if(feature.id in [4,5,6] return "otherstyle";
}

after some operations, A=[1,2,3,5], B=[4], and I generate std::string by replace the array in JS. So the script like below:

function getClass()
{
    if(feature.id in [1,2,3,5]) return "normalstyle";
    else if(feature.id in [4]) return "otherstyle";
}

after call featuremodellayer.dirty() the render image is same as before. there are no difference;
means the script is not update
I check the code in FeatureModelGraph, the _session is create after add to map, and never changed. _session only rebuild scriptengine when styles() is not set, however when add to map, the stylesheet of session has been seted, and never changed.
May I miss some thing, about update script? Or I need modify the source code?
Thanks for any help.

No, unfortunately there is no way to change the script dynamically. This would be a new feature request. Let us know if you come up with another solution!
