I have a form inside a modal dialog and after closing (hiding in fact) one I wanted to reset all inputs that user might have changed. I though about something like as follow:
<p:dialog widgetVar="myDialog">
<h:form id="formId">
<!-- ... -->
<p:commandButton value="Cancel" onclick="myDialog.hide();"
update="formId">
<p:resetInput target="formId" />
</p:commandButton>
</h:form>
</p:dialog>
But the result was not that I expected. After a while of searching I found a solution that was to add process="#this" attribute to the <p:commandButton>. And my question is why it is necessary? What is really happening in backgroud that this process is desired. I don't really get the idea of process attribute at all.
I have done some work with dialog boxes and the way I did to make the form null is, when clicking the button to open dialog box, I ran a method in backing bean which cleared my pojo so my form had empty values.
In your case it could be something like this:
<h:form id="form-button">
<p:commandButton id="AddButton" value="open dialog box"
update=":form" action="#{myBean.myMethodToSetPojoNull}" immediate="true"
oncomplete="PF('myDialog').show()" />
</h:form>
When clicking this button, the called method will set to null all the fields and your dialog box will be empty. Getting back to your question of why process=#this is neccessary much better explained answer is here
What is the function of #this exactly?
You can also reset input after submitting through this method:
<p:commandButton value="Reset Non-Ajax"
actionListener="#{pprBean.reset}" immediate="true" ajax="false">
<p:resetInput target="panel" />
</p:commandButton>
If you don't add process="#this" then by default attribute value will be set to process="#form" which means all the elements in the form are processed. In command buttons process="#this" is mandatory to execute the corresponding actions associated with that button.

I have a list of objects (let's call each object a record object), shown through a <p:datatable> component. Each record has a delete button column.
When a user clicks on the delete button of the record, a <p:confirmDialog> is shown, asking for user confirmation. What I want is to customize the content of the confirmDialog under corresponding circumstances (for example show/do not show a checkbox concerning the value of a property of the record, f.e if record.isPersonal, show the checkbox, else not.
Unfortunately, that does not seem to be working as the checkbox is always shown in case the first record satisfies the condition, and the opposite in case it does not. After some research I found out that especially in previous Primefaces versions, they used to use the "JS way" (creating two separate confirm dialogs and proportionally use PF('widgeName').show(), but I would like to know whether any out of the box solution exists in Primefaces 7.0 version which I use through the <p:confirm> tag or something else. Code example below:
<p:dataTable id="recordsTable" lazy="true" value="#{myBean.myList.records}" var="record...">
<p:column styleClass="deleteColumn">
<p:commandButton ...>
<p:confirm .../>
</p:commandButton>
<p:confirmDialog widgetVar="delete_record_dialog" global="true" showEffect="fade" hideEffect="fade">
<p:selectBooleanCheckbox
rendered="#{record.isPersonal}"
....>
</p:selectBooleanCheckbox>
<p:commandButton value="#{msg.yes}" type="button"
styleClass="ui-confirmdialog-yes" icon="pi pi-check"
/>
<p:commandButton value="#{msg.no}" type="button" styleClass="ui-confirmdialog-no"
icon="pi pi-times"
/>
</p:confirmDialog>
</p:column>
</p:dataTable>
Thanks in advance!
I think rather than using ConfirmDialog, you may have to revert to building you own custom dialog, either using p:dialog or using the dialog framework. Using dialog framework you can create a simple confirm dialog box and can pass the data into the dialog programatically - e.g. a flag based on the current row to indicate if the checkbox should be shown. The dialog framework also gives an easy way to return data back from the dialog to the calling page using the dialogReturn ajax event.
You could use the <p:confirmDialog message=""/> to conditionally display different messages like this:
<p:confirmDialog widgetVar="delete_record_dialog"
header="Record delete"
message="Are you sure you want to delete #{record.isPersonal ? 'your personal' : 'this'} record?">
<h:form id="recordDeleteForm">
<p:commandButton value="#{msg.yes}" update=":tableForm"
oncomplete="PF('deleteDialog').hide(); PF('recordsTableWidgetVar').filter()"/>
<p:commandButton value="#{msg.no}" type="button"
onclick="PF('delete_record_dialog').hide()"/>
</h:form>
</p:confirmDialog>
If you want to fit in more content then you could use <f:facet name="message">...</f:facet/>

Is it possible to reset the value of an inputText after clicking on the commandButton in JSF? The inputText UIElement provides the method ResetValue so I tried something like this:
<h:inputText id="measurementadd" binding="#{inputTextMeasurement}">
<f:validateRegex pattern="[a-zA-Z ]*"/>
<f:ajax event="keyup" render="measurementaddmessage submit" execute="#this"/>
<h:inputText>
<p:commandButton id="submit" action="#{Bean.addMeasurement(inputTextMeasurement.value)}"
value="submit" update="dataTable measurementadd measurementaddmessage"
disabled="#{empty inputTextMeasurement.value or facesContext.validationFailed }" >
<f:ajax event="mouseup" execute="#{inputTextMeasurement.resetValue()}" />
</p:commandButton>
<h:messages for="measurementadd" id="measurementaddmessage"/>
But after clicking the Button the inputTextMeasurement doesn't reset it's value.
Does someone know a good workaround for this?
I'm searching for a solution without JS and JAVA, so a realization in JSF would be very cool.
Your mistake is here in the execute attribute:
<f:ajax event="mouseup" execute="#{inputTextMeasurement.resetValue()}" />
The execute attribute should represent a space separated collection of client IDs to include in the process/decode of the ajax request. However, you specified a listener method there.
You need the listener attribute instead:
<f:ajax listener="#{inputTextMeasurement.resetValue()}" />
(and I omitted event as it defaults here to click which is already the right one)
Interesting detail is that the other <f:ajax> in the same piece of code used the exeucte attribute the right way.
Unrelated to the concrete problem, have you looked at <p:resetInput>? This saves an ajax listener method in the bean. Replace the whole <f:ajax> with
<p:resetInput target="measurementadd" />
Why dont we just use
<input type="Reset"/>
This one is works fine for me! ???
I have solved my problem as below
<p:commandButton id="submit" action="#{Bean.addMeasurement(inputTextMeasurement)}">
Sending back bean UIInput component. Get and Reset value in back bean.
public void addMeasurement(UIInput
String msr = (String) inputTextMeasurement.getValue()
inputTextMeasurement.resetValue();
}
I have two primefaces dialog that are inside in one h:form and i want to submit some required values from one dialog without submit required values from the other one:
<h:form>
<p:dialog modal="true" widgetVar="A">
<h:inputText value="#{bean.value}" required="true" />
<p:commandButton value="A" action="#{bean.someAction}" />
</p:dialog>
<p:dialog modal="true" widgetVar="B" >
<h:inputText value="#{bean.otherValue}" required="true" />
<p:commandButton value="B" action="#{bean.someOtherAction}" />
</p:dialog>
</h:form>
If i press commandButton A the validation of required value inside dialog B dont let me submit values from dialog A.
How can i do that?
The best and the logical solution is to split dialogs into separate forms. Moreover, the best practice is to put the form inside the dialog, and not vice versa.
Another solution is to explicitly tell JSF/PrimeFaces what to update and to process during an ajax request by specifying the corresponding attribute of your command button, or nesting an ajax tag inside the button.
I have a question. Is that possible to update two components at a time?
I am trying a code like this:
<h:panelGroup id="pickList">
<p:panel rendered="#{customCalender.visible}" widgetVar="searchTableBox">
//Some codes.....
<p:commandButton value="Cancel" update="pickList" actionListener="#{customCalender.closeList}" style="background:#25A6E1;color:red;font-family:'Helvetica Neue',sans-serif;font-size:10px;border-radius:4px;" />
<p:commandButton value="Save" update="custDataTablePanel" actionListener="#{customCalender.saveTargetList}" style="background:#25A6E1;color:red;font-family:'Helvetica Neue',sans-serif;font-size:10px;border-radius:4px;"/>
</p:panel>
</h:panelGroup>
....
.....
<h:panelGroup id="custDataTablePanel">
<p:panel rendered="#{customCalender.dataTableVisible}">
..
..
</p:panel>
</h:panelGroup>
Now I want when I click on the Save button it hides the <h:panelGroup id="pickList"> and displays the <h:panelGroup id="custDataTablePanel"> so I have two boolean values to control their visibility. but I need to update two of these panels. One I did with update="custDataTablePanel" it displays the data table after the button click.(in the method saveTargetList I updated the visibility of the custDataTablePanel to true.) but cant manage to hide the panel pickList.
So I was wandering is there any way to hide and show these two panels in one button click.
Please suggest.
You can use many elements in the update attribute separated by a space
<p:commandButton update="element1 element2"/>
also you can update the whole form by using update="#form"
I have a dialog on one of my pages. It opens fine. It works fine if you use the button on the page, it closes. However, if you try and "x" out of the dialog it will not close. I believe it is related to the fact that I have an input field on the dialog, but I am not sure. I apologize if this is a dupe, I could not find a similar post.
<p:commandButton action="#{phoneListBean.debugger}"
value="Merge Unqiue" onclick="mdlg.show();"
update=":pmsg, :createNewPanel, :listform" />
<p:dialog id="mdialog" header="Merge Unqiue" widgetVar="mdlg"
appendToBody="true">
<h:form id="mform">
<h:panelGrid columns="2" cellpadding="5" id="m">
<h:outputLabel for="listName" value="Enter the List Name:" />
<p:inputText value="#{phoneListBean.mergeList.name}" id="listName" />
<p:commandButton action="#{phoneListBean.mergeUnique}"
value="Merge Unqiue" update=":pmsg, :listform"
onclick="mdlg.hide();" />
</h:panelGrid>
</h:form>
</p:dialog>
Thanks in advance for the help.
Your problem is that you don't want to use the onclick attribute with Primefaces buttons for displaying and hiding the dialogs. The click event may not get invoked before the postback because these buttons are not Ajax enabled.
Instead you should use oncomplete attribute. This will notify the Javascript event to execute only after the server postback has occurred, meaning that show() will display already updated dialog contents, and hide() will occur only after the server side execution has finished.
