How to reset the inputfile in form after submitting the form with a file in ADF

Vidya HugarJan 21 2016 — edited Jan 28 2016

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());

}

Please Help Me

Hi,

Try this..

use value binding variable of the inputFile to reset the value like below,

setFile(null);

AdfFacesContext.getCurrentInstance().addPartialTarget(inputFileBinding);

Do as Timo Suggests

You are calling reset on ActionEvent component that means you are resetting your button not inputFile

ResetUtils.reset(actionEvent.getComponent());

Instead of this code bind your inputFile to bean and call Reset on that component binding

Ashish

Hi,

check this:

inputFileBinding.setValue(null);

AdfFacesContext.getCurrentInstance().addPartialTarget(inputFileBinding);

Thanks,

Prashant

I tried

inputFileBinding.setValue(null);

AdfFacesContext.getCurrentInstance().addPartialTarget(inputFileBinding);

also

but its taking lot of time, actually its loading . when i explicitly refresh then its fine.

even i tried ResetUtils.reset(actionEvent.getComponent());

still the same.

Vidya Hugar

I can do like theis, it works but as per my requirement i cannot add reset button

Timo Hahn

Sorry, I don't get you. I just added a button to get to the bean ad have a chance to reset the inputfile component. You can do it in your code as you are already in a bean method. You may have to ppr the inputFile component but it shoudl work.

Have you really read my comment ??

I am saying that you have used ResetUtils.reset(actionEvent.getComponent()); but you should not use this
Bind your inputFile to managed bean and call reset on that binding As Timo already told you

Ashish

I gave binding to the input file and tried to reset but still its not working for me, its trying to reset.

Here is my code for that

<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>

and JAVA class is

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

setInputFileBinding(null);

As Timo suggested its works but I cannot add the reset button for resetting the input file,

Thanks

Timo Hahn

Again, you don't need a special reset button. You can reset the inputFile after you saved the document

genericSaveDocuments(actionEvent, iter, myfile, binding, popUpId, "Portfolio"); // Saves the Document
this.getInputFileBinding().resetValue();

should do.

No. its not working for me.. next time when i try to add a record still its showing last inserted document

Timo Hahn

A you have set the value property of the inputFile, you have to set the value to null too.

Answer

See this line in your code

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

You are using a variable as value of inputFile so you have to set it's value to null

Write like this -

this.setFile(null);

// Reset inputFile component after upload

ResetUtils.reset(inputFileBinding);

hi Timo,

I did like this.

genericSaveDocuments(actionEvent, iter, myfile, binding, popUpId, "Portfolio");

this.getInputFileBinding().resetValue();

this.setInputFileBinding(null);

but still its not resetting.

Cvele_new_account

Try with:

this.getInputFileBinding().resetValue();
this.getInputFileBinding().setValue(null);
AdfFacesContext.getCurrentInstance().addPartialTarget(getInputFileBinding());

Vidya Hugar

Thanks a lot . its working @"Timo Hahn" @ashish awasthi
