Change elements of subview

[Former Member]

Hi,

i have a view where another view is embedded:

<mvc:View controllerName="account.controller.Main" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m">
  <App>
  <pages>
  <Page title="{i18n>title}">
  <content>
  <sap.ui.layout.form:SimpleForm ariaLabelledBy="__text5" columnsL="1" columnsM="1" editable="true" emptySpanL="1" emptySpanM="1" id="__form0"
  labelSpanL="4" labelSpanM="4" layout="ResponsiveGridLayout" maxContainerCols="2" xmlns:sap.ui.layout.form="sap.ui.layout.form">
  <sap.ui.layout.form:content>
  <Label labelFor="idFertigungsauftrag" text="{i18n>Fertigungsauftrag}"/>
  <Input busy="false" editable="true" id="idFertigungsauftrag" width="100%"/>
  </sap.ui.layout.form:content>
  </sap.ui.layout.form:SimpleForm>
  <mvc:XMLView viewName="account.view.Rueckmeldung"/>
  </content>
  <footer>
  <Toolbar>
  <ToolbarSpacer/>
  <Button icon="sap-icon://accept" id="idConfirmBtn" press="onPressConfirmBtn" text="{i18n>Rueckmelden}" type="Accept"
  visible="true"/>
  <Button icon="sap-icon://sys-cancel" id="idCancelBtn" press="onPressCancelBtn" text="{i18n>Abbrechen}" type="Reject"
  visible="true"/>
  </Toolbar>
  </footer>
  </Page>
  </pages>
  </App>
</mvc:View>

In this subview I have input fields. Over the button in the footer I want to clear the input fields of the subview.

Within this button-method, I can call a function of the controller of the subview: sap.ui.controller("hauni.controller.Rueckmeldung").clear();

But within this function, I can not access this and so I can not get the elements of the view

clear: function() {












this.byId("idGutmenge").setValue("");





this.byId("idAusschuss").setValue("");





this.byId("idEntlohnungsmenge").setValue("");





this.byId("idNCProgrammnummer").setValue("");










}

Has anybody an idea how to handle this?

Thank you in advance!
