Hola, tengo este botón que lanza unos cálculos y tiene que rellenar el grid. En las trazas sale un nullpointer con referencia al grid. Es como si se calculara todo bien pero en el último paso no es capaz de mostrar los datos.

<button icon="search" label="BUTTON_CALCULATE" id="ButSch" button-type="submit">
            <button-action type="server" server-action="maintain-silent" target-action="FmbSdtEvnCdiDiaJav"/>
            <button-action type="server" server-action="dataTrt" target-action="TrtFmbEvnEquDvdEstViw"/>
            <button-action type="filter" target="GrdEquDvdEst" />
          </button>
        </tag>
      </tag>
    </window>
    <tab id="Tab1" initial-load="enum" target-action="EnuTabSdtCcpGrd" maximize="true"> 
      <tabcontainer id="EnuTabCcpGrd" label="Resultados" style="expand">
        <grid id="GrdEquDvdEst" style="expand" server-action="data" autoload="false">
          <column align="center" label="COLUMN_FMB_BO_SEC"  name="GrdSec"    sort-field="GrdSec" charlength="25" sortable="true"/>

          <column align="left"  label="COLUMN_FMB_DT1"  name="GrdDt1" sort-field="GrdDt1"    charlength="25" sortable="false" />
          <column align="left"  label="COLUMN_FMB_SDT_EQU_EQE"  name="GrdEqe" sort-field="GrdEqe"    charlength="25" sortable="false" />

        </grid>

[ERROR] [Message] Error en la Obtención de datos (null)
[ERROR] [Input Parameters]: callId="call-20", screen="SdtEvnEquDvdEst", address={"view":"report","component":"GrdEquDvdEst"},

Creo que me falta algo en el código pero no sé qué puede ser.

¿Alguna ayuda? Gracias
