GanttDataSource - transport-parameter-map is never called

[Al]

I have the code below as per the docs, all is fine except the parameter map function never gets called (for any operation, read or create etc.)

 

    <ganttdatasource ref="ganttdatasource1"
        :transport-read="gRead    
        :transport-parameter-map="parameterMap"
        ......
    </ganttdatasource>

    <gantt
        data-source-ref="ganttdatasource1"
......
    ></gantt>

    methods: {
        parameterMap: function(options, operation) {
            console.log("parameterMap!", options)       //Never see this
            .....
        }

Hi Al,

I don't know the whole Gantt and DataSource implementation that you have in your application, but here is a StackBlitz example demonstrating how the parameterMap function is executed on every read call. 

You can compare the provided example to the implementation in your application. Thus you may notice what is the reason why the parameterMap is not called. 

Another reason why the parameterMap is not called is the notice from the second link above: "The parameterMap function will not be called when using custom functions for the read, update, create, and destroy operations."

I hope the above details will help you resolve the issue in your application.

Thanks, I missed this bit in the docs: "The parameterMap function will not be called when using custom functions for the read, update, create, and destroy operations."
