when load state -> custom editor is not rendered as expected

when load 

 

 

expected

change event is not fired too

this is because you lose editor info deserializing state, basically, you save to state all options, but just what can be changed, wired approach

[Aleksandr]

if (options.fields) {
    options.fields.forEach((element) => {
        switch (element.name) {
            case 'StateId':
                element.editorTemplate = stateEditor;
                break;                        
            case 'AgencyId':
                element.editorTemplate = agencyEditor;
                break;
            default:
                console.log(`Sorry, we are out of ${expr}.`);
        }
    });
}

externalFilter.setOptions(options);

will restore, but again, seems you did it in the wrong way, just save to state what can be changed & restore it the same way, fields are not going to be changed, they are predefined

Hello, Aleksandr,

This behavior is expected as this is how the JSON.stringify method works. As stated in the setOptions article, JSON.stringify() cannot serialize function references (e.g. event handlers). A possible approach to handle the scenario is demonstrated in this How-To article. Even though it is about the Grid, the principle is the same.

Let me know if you have any questions.

in general i do not understand why you serialize predefined part rather then just possible expression? just expressikn can be changed

Hello Aleksandr,

I am not sure I understand the question. That is how the JSON.stringify method works. Kindly let me know what I am missing.
