primefaces: Execute action before update in commandlink - jsf

Question

I have a Dialog and a CommandLink which shows this dialog. In this Dialog i display values which has created during the action (or propertyListener) of the command link. But because the update is executed before the action, the variables are not set.
<p:commandLink update="#form:myDialog" action="#{myBean.setText('text')}"
oncomplete="myDialog.show()">
</p:commandLink>
....
<p:dialog widgetVar="myDialog" modal="true">
<p:inputText value="#{myBean.text}" />
</p:dialog>
Is it possible to execute an action before the update is done?

Answer 1

I dialog will update you haven't specified the Id attribute of the dialog
<p:commandLink update="myDialog" action="#{myBean.setText('text')}"
oncomplete="myDialog.show()">
</p:commandLink>
<p:dialog Id="myDialog" widgetVar="myDialog" modal="true">
<p:inputText value="#{myBean.text}" />
</p:dialog>
This will help you .
But what i prefer is use an outputpanel
<p:commandLink update="myDialogPanel " actionlistner="#{myBean.setText('text')}"
oncomplete="myDialog.show()">
</p:commandLink>
<p:dialog Id="myDialog" widgetVar="myDialog" modal="true">
<p:outputPanel Id=myDialogPanel >
<p:inputText value="#{myBean.text}" />
</p:outputPanel>
</p:dialog>
or you can update the dialog from managedBean and show the dialog. This is helpful if you get any error at your managedBean method your dialog is not show.
RequestContext.getCurrentInstance().update("myDialogPanel");
RequestContext.getCurrentInstance().execute("myDialog.show();");

Answer 2

You can open the Dialog from ManagedBean itself.
RequestContext.getCurrentInstance().execute(myDialog.show());
RequestContext can be used to Execute any javascript from ManagedBean.
You can also update the components from Managed Bean using RequestContext's Update
method.
RequestContext.getCurrentInstance().update("COMPONENT_ID");
