Have a output text as a part of command button

I want to insert outputText in the value attribute of a commandButton. The problem I am facing here is that the 'value' attribute of the commandButton only takes static text as value but I want this text to change according to the value assigned to that list and the whole value should be displayed inside the commandbutton.

<h:commandButton id="submit-button" styleClass="click_button1"
                                type="submit" value="Yes"
                                action="#{xyz.deleteAction(o)}" update="msgs" />

In this, instead of "yes", I want something like this

Yes, I want this thing <h:outputText size="15" value="#{o.name}" /></b> from <h:outputText size="15" value="#{o.detals}" /></b>

as the value.

Solution

If you really need some h:outputText features such as escape="false" then your best bet is to use h:commandLink instead. You may need to tweak your CSS if you want to get a look and feel close to h:commandButton.

<h:commandLink id="submit-button" styleClass="click_button1" action="#{xyz.deleteAction(o)}" update="msgs">
     Yes, I want this thing <h:outputText value="#{o.name}" /> from <h:outputText value="#{o.detals}" />
</h:commandLink>

If you only need to display some dynamic values then you can perfectly use an EL expression

<h:commandButton id="submit-button" styleClass="click_button1" type="submit" value="Yes, I want this thing #{o.name} from #{o.detals}" action="#{xyz.deleteAction(o)}" update="msgs" />

Notes:

I removed the </b> tags from your example as this looks like a typo from me.
As BalusC stated in his comment, h:outputText doesn't have a size attribute.
