I am using oracle 12c. I have a form where i have 3 input fields and one af:inputFile where i need to upload the file and final save.

I cannot use valueChangeEvent for inputFile because if i user ResetUtils then i will not get the form input values.

On save everything works fine but when i again add a record then the last updated file still shows in inputFile(its not resetting).

After save if i set the input file binding to null then do partial trigger for the component using binding its loading the page taking huge time to save so i cant use it.

Here is my code

<af:panelFormLayout id="pfl1" rows="3">

           <af:inputText value="#{bindings.Filename.inputValue}" label="#{bindings.Filename.hints.label}"

                                    required="#{bindings.Filename.hints.mandatory}"

                                    columns="#{bindings.Filename.hints.displayWidth}"

                                    maximumLength="#{bindings.Filename.hints.precision}"

                                    shortDesc="#{bindings.Filename.hints.tooltip}" id="it9"

                                    contentStyle="width:150px" showRequired="true">

                        <f:validator binding="#{bindings.Filename.validator}"/>

                      </af:inputText>

                      <af:panelGroupLayout id="pgl350" layout="horizontal">

                        <af:inputFile label="Select" id="if51" value="#{ContractDocumentUploadDwn.file}"

                                      showRequired="true" binding="#{ContractDocumentUploadDwn.inputFileBinding}"/>

                        <af:button text="Upload" id="b353" action="#{ContractDocumentUploadDwn.uploadPortfolioDoc}"/>

                      </af:panelGroupLayout>

                    </af:panelFormLayout>

Java Code:

    public void savePortfolioDoc(ActionEvent actionEvent) {

        // Add event code here...

        DCIteratorBinding iter = getDCIteratorBinding("portfolioDocument1Iterator");

        UploadedFile myfile = (UploadedFile) this.getInputFileBinding().getValue();

        String binding = "Commit1";

        String popUpId = "p2";

        genericSaveDocuments(actionEvent, iter, myfile, binding, popUpId, "Portfolio");//Saves the document

        iter.executeQuery();

        iter.refresh(1);

        setInputFileBinding(null);

        ResetUtils.reset(actionEvent.getComponent());

    }
