p:message attached to a h:form - jsf-2

I have two forms in my page, in the first formulary are input fields with validation, and in the other a dataTable. The first formulary has a message area to show validation errors, and the second formulary has a message area to show problems with the retrieval of the data (this message area is updated from myController.search).:
<h:form id="form1">
<p:message id="messageForm1" for=":form1" />
<p:inputText id="text1" value="#{myBean.data}" required="true" />
....
<p:commandButton value="Search" actionListener"#{myController.search}"
update=":form2:dataTable :form2:messageForm2 :form1:messageForm1" process="text1, ..." />
</h:form>
<h:form id="form2">
<p:message id="messageForm2" for="messageForm2" />
<p:dataTable>
...
</p:dataTable>
</h:form>
The problem is that the messages in the form2 are working, but the validation messages in form1 are never shown

The description of the for attribute of the p:message tag says:
Id of the component whose messages to display.
So you can't specify the ID of the form. You have to specify the ID of a single form component. e.g. <p:message id="messageForm1" for="text1" />. But then you have to create one message element for every form component.
An alternative would be to use the p:messages tag. For examples see here: http://www.primefaces.org/showcase-labs/ui/messages.jsf

JSF command button updating even there are validation errors

I'm new to JSF, my question may be silly for you.. It is very much valuable for me..
<h:form id="form1">
<p:messages autoUpdate="true" showDetails="true" />
<p:dataTable id='form1ID'>....</dataTable>
<p:inputText value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
</h:form>
<h:form id="form2">
<p:messages autoUpdate="true" showDetails="true" />
<p:dataTable id='form2ID'>....</dataTable>
<p:inputText value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
<p:commandButton value="Submit" update=":form1:form1ID"
actionListener="#{mgmtBean.doCreateType}" />
</h:form>
I have two forms. when I click on form2 command button with empty fields, it will show error messages perfectly since i have added <p:messages autoUpdate="true" showDetail="true"/>.
The bad thing or surprising thing here for me is, it is showing error messages on top of form1 also may be because of <p:messages autoUpdate="true" showDetail="true"/> added in form1 and i'm trying to update form1 on command button click in form2.
I don't want to show error messages on form1 when form2 is throwing validation error messages. How can i fix this ? I googled it out.. but couldn't find the solution.
Evironment i'm using is jsf-api-2.1.5 and primefaces 4.0 version and view technology is facelets(XHTML)
Hope it is clear..
Any idea is highly appreciated.
Try to disable rendering of messages on the form1:
<p:messages autoUpdate="true" showDetails="true" rendered="#{bean.renderedmessage}"/>
And in the bean, add the renderedmessage variable:
public Boolean getRenderedmessage() {
return renderedmessage;
}
/**
* #param renderedmessage the renderedmessage to set
*/
public void setRenderedmessage(Boolean renderedmessage) {
this.renderedmessage = renderedmessage;
}
And, for the doCreateType() method, add:
public void doCreateType(){
..............
setRenderedmessage(false);
.............
}
After the form1 is updated, you can choose some event or method, where you can setRenderedmessage(true);
What you're currently experiencing should indicate to you that you usually don't need two <p:messages/>s in the same JSF view; one is enough.
Regardless of the fact that you have two <h:form/>s on your page, there's still only one FacesContext associated with that view (The FacesContext object is a JSF construct that encapsulates all the information/data/components etc that's associated with a given JSF page request).
By default the <p:messages/> will display every FacesMessage that is queued within it's associated instance of FacesContext, regardless of the source of the message (well, almost: if you set globalOnly="true" on the <p:messages/>, you can change that behaviour).
That being said, you basically have two options:
Get rid of the extra <p:messages/> and rely on (and appropriately position) only one to display all errors/warnings for that view
Specify the for attribute, set to the desired component. Doing so, you'll guarantee that only one input component can trigger the display of its associated message component. For example
<h:form id="form1">
<p:messages for="inputName" autoUpdate="true" showDetails="true" />
<p:dataTable id='form1ID'>....</dataTable>
<p:inputText id="inputName" value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
</h:form>
Note that I've set an id attribute on the <p:inputText/> component; this is necessary so you can use it in the for attribute for the messages component.

What is FacesContext used for?
I have fixed the issue by using the following code
<p:messages autoUpdate="true" showDetails="true" visibility="info"/>
so it is just displaying info messages and other pop up error messages will not be showun.

how to reset form inputs after they are submitted in jsf

so i have this code(not in details)
<p:tabView id="tabviewId">
<p:tab>
<h:form id="mainHeadOfAccountsId_form">
// some input fields with validation
// using viewscoped
<p:commandButton value="Add" process="mainHeadOfAccountsId_form" update="mainHeadOfAccountsId_form :#{p:component('allMainHeadOfAccountsId_table')} :#{p:component('successfullySavedUpdatedId_growl')}" action="#{budgetHeadOfAccountsAction.addMainHeadOfAccountsOnAjax}" />
/// also using <p:datatable id= "allMainHeadOfAccountsId_table" >
</h:form
</p:tab>
<p:tab>
<h:form>
</h:form
</p:tab>
</p:tabView>
<p:growl id="successfullySavedUpdatedId_growl" for="successfullySavedUpdatedFor_growl" value="error" showDetail="false" />
my Question is that when i submit form mainHeadOfAccountsId_form successfully i need to update(reset) all fields which are in mainHeadOfAccountsId_form
but remember that i am also using <h:selectOneMenu> so i want to reset(option[0] selected) not empty, how can i do that ? currently its updating allMainHeadOfAccountsId_table and successfullySavedUpdatedId_growl except mainHeadOfAccountsId_form
i have tired tabviewId:mainHeadOfAccountsId_form but getting exception component not found,
as i am thinking this is just because of #viewScoped and i should reset value of those inputs in my action class (.java), m i right ?
see what primefaces offer for reset input or after submitting the form by the action in the bean reset the values by new or null and recreate the list held by
<h:selectOneMenu>

Why does required="true" not fail validation when disabled="true" is specified

<a4j:outputPanel id="tapalSectionSendToPanel" ajaxsingle="true">
<h:inputText id="sendToId1" value="#{MainBean.SectionBean.sendTo}"
class="createresizedTextbox"
required="true" requiredMessage="#{msg.labl_required}"
disabled="true" />
<h:message for="sendToId1" style="color:red" />
</a4j:outputPanel>
i need to validate textbox for empty validation and should show required when i click button without entering any value in textbox. It works fine without disabled="true". Whats the alternative for my requirement.
First, required and disabled don't go well together, because they are mutually exclusive as per the JSF Spec:
required: Flag indicating that the user is required to provide a submitted value for this input component.
disabled: Flag indicating that this element must never receive focus or be included in a subsequent submit.
Like I said in the comments, you can just display a message when the user tries to submit the form without selecting a node:
<h:inputText id="sendToId1" value="#{MainBean.SectionBean.sendTo}"
styleClass="createresizedTextbox" required="true" readonly="true" />
<h:message for="sendToId1" value="#{msg.labl_required}"
rendered="#{facesContext.postback and facesContext.validationFailed}" />
As an alternative you can just display a text anywhere in your markup:
<h:outputText value="#{msg.labl_required}"
rendered="#{empty MainBean.SectionBean.sendTo}" />
disabled="true" disables the input (so it's skipped when the form is submitted), if you don't want the user to type in it use readonly="readonly"

Issue with displaying Error message in a page having two forms

I am developing one JSF page, in that i am having two forms. And I am using rich:messages in both the forms.
Suppose, in the first form, if I don't enter any required fields and I click Save, then error messages are displaying twice in the page(as i am using rich:messages in two forms).
Is there any way so that error messages display with respect to the form?
Thanks in advance.
If you are using RichFaces 3.3.3.Final you can do it like so:
<a4j:form id="tmpfrm1">
<rich:messages />
<h:inputText value="#{mybean.intmp1}" required="true"/>
<a4j:commandButton value="save" action="#{mybean.test1}" reRender="tmpfrm1" limitToList="true" />
</a4j:form>
<a4j:form id="tmpfrm2">
<rich:messages />
<h:inputText value="#{mybean.intmp2}" required="true"/>
<a4j:commandButton value="save" action="#{mybean.test2}" reRender="tmpfrm2" limitToList="true" />
</a4j:form>
If you are uisng RichFaces 4 you need to replace the limitToList with limitRender and the reRender with render

pass a list as input parameter in jsf

I have a page in jsf, where the user enters all the data and clicks on submit button, and it has to be saved in the database. Please find the code i'm currently using.
<h:column>
<f:facet name="header">
<h:outputText value="Registration"/>
</f:facet>
<h:form>
<h:commandLink id = "submit" value="submit" action="#{bean.submitDate}">
<f:param name="sNum" value="#{list.sNumber}" />
<f:param name="firstName" value="#{list.fName}" />
<f:param name="lastname" value="#{list.lName}" />
...
</h:commandLink></h:form>
</h:column>
i wanted know if i can send whole data at a time or I have to send all the fields individually itself as above
Although I don't see any input fields in your code snippet:
You can send all input elements together. Just let one single <h:form> ... </h:form> wrap all your input elements and use one h:commandLink or h:commandButton inside the form to submit all data together.
