[Question] Were there changes to how data should be loaded into the form?

[Svitra]

Hi,

Until now I was loading data into the form in (render) method by setting them like this: this.formio.formio.submission.data = myDataObject (where this.formio is a viewchild FormioComponent that is not static). I updated the Angular to 9 and formio as well (now I have "angular-formio": "^4.7.4" and "formiojs": "^4.9.17") and now this piece of code is causing the data to appear and disappear right after. The submission object appears to be cleared later. Is there some change to how data should be loaded into the form?

I too have this issue. It looks like a bug to me. In my case, I'm loading multiple forms as Material tabs, and want to pre-populate the values to make a RESTful configuration UI. The Form has been mutating my submission object, and refuses to take the values that I try to prepopulate.

I was able to get it working with the following "hack".

Component.html:

...
  <mat-tab *ngFor="let schema of configSchemas" [label]="schema.file">
    <mat-formio [submission]="{data: schema.config}" (submissionLoad)="render($event, aG(schema.sConfig))" [form]="schema.schema" (submit)="saveConfiguration($event)"></mat-formio>
  </mat-tab>
...

Component.ts

...
  aG(f){
    return JSON.parse(f);
  }
  render(a: any, b: any){
    a.data = b;
  }
...

In my case, the schema is an object like so:

{
  schema: <FormIO JSON>,
  file: <FormIO JSON File Path>,
  config: <Stored Configuration>
}
