PCF Model Driven App - Not all records are loaded (Dataset)



It seems that some of the properties in the dataset, is not behaving the way i would think.


1:  context.parameters.dataset.paging.totalResultCount is sometimes showing -1 (Is this property even supported?, it is in the typescript definitions)


2: Randomly, dataSet.paging.hasNextPage is undefined, while dataSet.loading is false, but all the records is not loaded into the dataset yet.


3: Sometimes, dataSet.paging.loading is true, but all records are in the dataset (create unnecessary extra dataload)



I have created this test script:


I have a view with 15500 records, and 15-20 % of the time, not all records are loaded into the dataset, am i missing something here?





public init(context: ComponentFramework.Context<IInputs>, notifyOutputChanged: () => void, state: ComponentFramework.Dictionary, container: HTMLDivElement) {
        this.container = container;
        var dataSet = context.parameters.Tasks;    
        if (dataSet.paging.totalResultCount > 0)
        else  dataSet.paging.setPageSize(5000);    









 public updateView(context: ComponentFramework.Context<IInputs>): void {
        var dataSet = context.parameters.Tasks;    
        if (dataSet.loading) {
            //If we know the totalResult, we can check if all are loaded
            if (dataSet.paging.totalResultCount > 0) { 
                if (dataSet.sortedRecordIds.length != dataSet.paging.totalResultCount) {
                    console.log("Length not same as totalcount",{...dataSet})
                console.log("Length same as totalcount",{...dataSet})
            //If the total result is unknown, we need to return to ensure all is loaded
            else {
        else {
            console.log("Dataset not loading",{...dataSet})
            console.log("Has next page:", dataSet.paging.hasNextPage )

        //if data set has additional pages retrieve them before running anything else
        if (dataSet.paging.hasNextPage ) {                 
           console.log("Load count", this.count);

        ReactDOM.render(React.createElement(App, { context }), this.container);

This was a error on our tenant. There was a onFormLoad script, that called after a call to update some rollup fields.

Hi @Kristoffer88 , 

I'm not sure about all details (since I've used loadExactPage instead ot loadNext Page) but maybe this brings you a step forward:

"paging.totalResultCount" is documented here 

but I wouldn't expect it to be set in the init method. I suggest to set the page size allways on 5000 (this should work also if there are less records)


 If I see right, if  

loading===true && dataSet.sortedRecordIds.length === dataSet.paging.totalResultCount

 there is no return, so you might land to loadNextPage() call, while still loading. 

About unceressary loads, I've seen similar behavior in my tests; but I work with react and let it treat the unnecessary calls.

Hope this helps. If not, please let me know.

Kind regards,


Thanks for the reply Diana.


The problem i am seeing, is that i cannot trust the loading and hasNextPage properties, sometimes loading is false og hasNextPage is false/undefined, but the dataset is not fully loaded yet.



I will try to use loadExactPage instead, and then i will try to upload the code as a solution, instead of using fiddler for testing. I suspect it could be something releated to that.
