Beetle Studio Developer Notes

This document is intended to be the "landing place" for information that would make a Beetle Studio developer's life easier. Each note should highlight in bold the keywords. Developers should add to this document any task steps, processes, debugging steps, URLs, or anything else to save the "next" developer time and effort.

• When upgrading patternfly-ng, you will also need to update the version of the Patternfly stylesheets referenced in src/index.html. One thing that may happen when the stylesheet version and the library version are not in sync is the components may not display.

• If running tests in the IDE and the test immediately aborts, kill the Karma server and rerun the test.

• If a variable of a class is nil when you know it really isn't, you are probably trying to access it from a callback handler. Change your code to save the object reference in a constant and use that in the handler code. Here is an example:

    const self = this;

    this.connectionService
      .getAllConnections()
      .subscribe(
        (connections) => {
          self.allConns = connections;
          self.filteredConns = this.filterConnections();
          self.loaded("connections");
        },
        (error) => {
          self.logger.error("[ConnectionsComponent] Error getting connections.");
          self.error(error);
        }
      );

• When using Response and ResponseOptions classes, make sure you use the version from the @angular/http library.
