Keep value of input fields not processed by ajax request

Question

I have a form which contains a table with two columns. Each row has a checkbox and an input field. While the checkbox is for deletion of the specific row, the input field is for (mass)editing of the values. Each input field uses bean validation. Additionally I have two buttons: one for 'delete' and one for 'save'. Everything is based on primefaces.

<h:form>
    <p:dataTable value="#{backingBean.list}" var="entry" id="table">
        <p:column>
            <p:selectBooleanCheckbox value="#{entry.flagDelete}" />
        </p:column>

        <p:column>
            <p:inputText value="#{entry.value}" />
        </p:column>
    </p:dataTable>

    <p:commandButton value="save" actionListener="#{backingBean.save}" process="table @this" update="table" />

    <p:commandButton value="delete" actionListener="#{backingBean.delete}" process="@([type=checkbox]) @this" update="table" />
</h:form>

('process' equals 'execute' and 'update' equals 'render' in JSF 2)

Now it should be possible to delete the selected rows without the validation of the input fields. Therefore I used the primfaces ajax selectors (based on jQuery selector API) to select only the checkboxes, that should be processed during the ajax request. The values of the input fields are still send to the server but won't be processed.

The problem is the re-render of the table after the ajax request. I want the input fields to preserve the values that got entered before the delete-button was clicked (in case the user did not save his changes with the save-button). As those values got send to the server, this shouldn't be such a big deal (e.g. when the validation fails, I also get the last entered values). But actually I get the values, that are stored in the backing bean. Is there any option/solution on how to achieve this?
