12.0p: How to use JSONEncoder in showcase?

[Blama]

Hi Isomorphic,

this code works as expected:

isc.IButton.create({
    ID:"showImplicitCriteria", width: 200,
    title:"Show ImplicitCriteria",
    click : function () {
        isc.say(isc.JSON.encode(dsListGrid.getImplicitCriteria()))
    }
});

Thanks a lot,
Blama

You can either do var encoder = isc.JSON.... etc, or you can access window.encoder instead.

Hi Isomorphic,

can you show to to use your JSONEncoder clientside?

Creating another testcase, I tried this here (v12.0p_2018-12-13) and did not succeed:

isc.JSONEncoder.create({
    ID:"encoder"
});

isc.ListGrid.create({
    ID:"dsListGrid", 
    width: "100%",
    height: "100%",
    autoFetchData: false,
    canEdit: true,
    initialSort: [
        {property: "category", direction: "ascending"},
        {property: "units", direction: "ascending"}
    ],
    dataSource: "supplyItem",
    showFilterEditor: true,
    implicitCriteria: { fieldName: "units", operator: "isNull" },
});

isc.IButton.create({
    ID:"fetchButton", width: 200,
    title:"Fetch no criteria",
    click : function () {
        dsListGrid.fetchData();
    }
});

isc.IButton.create({
    ID:"fetchFilteredButton", width: 200,
    title:"units criteria fetchData()",
    click : function () {
        dsListGrid.fetchData({ _constructor: "AdvancedCriteria", fieldName: "units", operator: "equals", value: "Ea"});
    }
});

isc.IButton.create({
    ID:"showImplicitCriteria", width: 200,
    title:"Show ImplicitCriteria",
    click : function () {
        isc.say(encoder.encode(dsListGrid.getImplicitCriteria()))
    }
});

isc.HStack.create({
    ID:"hStack",
    membersMargin:10,
    members:[ fetchButton, fetchFilteredButton, showImplicitCriteria]
});

isc.VLayout.create({
    membersMargin:10,
    width: "100%",
    height: "100%",
    members:[ dsListGrid, hStack]
});

Error in the developer console on click of "Show ImplicitCriteria" is:

13:50:15.299:MUP1:WARN:Log:ReferenceError: encoder is not defined
