In datatable cell-editing...

[kimausoleil]

Hello!

I use a datatable to persist in a database.
And it works very well!

My problem occurs when I persist my data.
If I throw an exception because my data does not satisfy the constraints, my datatable still appears with the change.

How can I keep in cell-editing?

Or how to display the value of the database (which has not been updated) instead of those that have just been validated (which is wrong).

This is my code

Code: Select all

            <h:form>
                <p:dataTable var="typeSpectacles" value="#{typeSpectaclesController.typesSpectacles}" rowEditListener="#{typeSpectaclesController.rowEdit}" onRowEditUpdate="msgs" >

                    <p:column headerText="Code" style="width:70px">
                        <h:outputText value="#{typeSpectacles.code}" />
                    </p:column>

                    <p:column headerText="Libellé">
                        <p:cellEditor>
                            <f:facet name="output">
                                <h:outputText value="#{typeSpectacles.libelle}" />
                            </f:facet>
                            <f:facet name="input">
                                <h:inputText value="#{typeSpectacles.libelle}" style="width: 100%" />
                            </f:facet>
                        </p:cellEditor>
                    </p:column>

                    <p:column headerText="Opts" style="width:50px">
                        <p:rowEditor />
                    </p:column>

                </p:dataTable>
            </h:form>

and my function in my controller to persist :

Code: Select all

    public void rowEdit(RowEditEvent ev) {

        TypeSpectacles obj = null;
        try {
            obj = (TypeSpectacles) ev.getObject();
            ejb.edit(obj);
        } catch (Exception ex) {
            addMessage(ex);
        }

    }

Thank you!

Right now it only stay editable when validation is failed by checking FacesContext.getCurrentInstance().isValidationFailed() so when you catch the exception as a workaround you can try;

Code: Select all

public void rowEdit(RowEditEvent ev) {

        TypeSpectacles obj = null;
        try {
            obj = (TypeSpectacles) ev.getObject();
            ejb.edit(obj);
        } catch (Exception ex) {
            addMessage(ex);
            FacesContext.getCurrentInstance().validationFailed();
        }

    }

Ok !

[kimausoleil]

I'm sorry but an other question about this !

So now, when an exception is caught, it stays editable !
But if after I click to cancel, the message is still displayed !

Code: Select all

            <p:messages id="msgs" />            
            <h:form>
                <p:dataTable var="typeSpectateurs" value="#{typeSpectateursController.typesSpectateurs}" rowEditListener="#{typeSpectateursController.rowEdit}" onRowEditUpdate="msgs">


...

How can I mask it ?
There is action when we click to cancel ?

[kimausoleil]

I tried to use renderer property in p:messages...

But what can I test, and what does it do when I click to cancel button for cell-editing ?

If you just want the FacesMessage displayed for a short time and then hidden you should take a look at the growl component of PrimeFaces.

You're right !

But If I want to do another action when I click the cross to cancel in-cell editing...

I'd like a "cancelListener" !

May be one day...
