Errors on custom components (when persisting data and format label)

Hi, 

from yesterday my custom visuals have some issues when calling the following functions (that woked before): 

 

  • When persisting data:
    powerbi.data.SQExprBuilder.text(String(ANY_DATA))
  • When formatting a value (the following function return an empty string):
    dataLabelUtils.getLabelFormattedText(MEASURE, WIDTH, FORMAT_STRING, MEASURE_FORMATTER);

These issues affect the online version only, not the desktop (with the same code, of course).

Can you help me?

    Looks like you are passing SQConstantExpr type value (as per powerbi.data.SQExprBuilder.text() call) where persistProperties  method requires DataViewPropertyValue, so the following code works in both Desktop and Online:

     

                    SynopticPanelBySQLBI.prototype.persistData = function () {
                    var properties = {};
                    properties.imageData = (this.data.imageData ? this.data.imageData : '');
                    //properties.imageData = (this.data.imageData ? powerbi.data.SQExprBuilder.text(String(this.data.imageData)) : '');
                    this.host.persistProperties({
                        merge: [{
                            objectName: 'general',
                            selector: null,
                            properties: properties,
                        }]
                    });
                };

    PS. It works in Desktop as changes in SQExprBuilder have not been reflected to Desktop yet. Using primitive type instead of SQExprBuilder is correct way here.

     

    Thx!

    Confirm this issue:

     

     

    value
SQConstantExpr {type: ValueType, value: "https://www.sqlbi.com/synopticdesign/wp-content/up…s/sites/251/2015/12/gallery_map_1449167366471.svg", valueEncoded: "'https://www.sqlbi.com/synopticdesign/wp-content/u…/sites/251/2015/12/gallery_map_1449167366471.svg'"}

data.SQExprBuilder.text(value)

      Thank you very much!

      Is there a release date for the Power BI Desktop update that contains this fix?
