I'm combining a <p:selectBooleanCheckbox> and a <p:inputText>. The <p:selectBooleanCheckbox>´s value must be enabled/disabled the <p:inputText>. When <p:inputText> is enabled (<p:inputText> property disabled=false) the user is allowed to type a value to the input text field to later it be saved to a Database ( both values, checkBox and inputText). Everything is working fine, except that the value introduced to the inpuText object is not saved to data base. I'm using a PestgreSQL database, field dpNumPasaporte in database is numeric.
<p:selectBooleanCheckbox id="chkPasaporte"
value="#{DatosPersonalesBean.chkPasaporte}"
style="float: right;padding-top: 9px;" >
<p:ajax event="change"
update="inpPasaporte"/>
</p:selectBooleanCheckbox>
<p:inputText id="inpPasaporte"
value="#DatosPersonalesBean.datosPersonales.dpNumPasaporte}"
style="alignment-adjust: baseline; width: 190px"
disabled="#{!(DatosPersonalesBean.chkPasaporte)}">
</p:inputText>
Note: I tested the block <p:inputText> separately and it is saving in database.
Thanks in advance,
you must add an ajax event and I think that you have missed by entering the name of your Bean, you must add :
<p:inputText ... value="#{datosPersonalesBean.datosPersonales.dpNumPasaporte}` >
<p:ajax event="change" process="#this" />
</p:inputText>

I am using PrimeFaces 5.1, In my project dataTable to filter used.In text filter is work fine but dropdown filter is not working properly (i.e) In dropdown I show department,First time I choose any value from dropdown is work fine anothertime I choose dropdown It not return any value show in dataTable.I choose select one first value from dropdown also throw null pointer exception.
<p:dataTable id="datalist" widgetVar="datalist" var="user" value=#{beanList.userList}>
<p:column headerText="Department" filterBy="#{user.deptname}"
filterMatchMode="exact" >
<f:facet name="filter">
<p:selectOneMenu onchange="PF('datalist').filter()">
<f:selectItem itemLabel="ALL" itemValue="#{null}"
noSelectionOption="true" />
<f:selectItems value="#{datalist.deptList}" />
</p:selectOneMenu>
</f:facet>
<h:outputText value="#{user.depatname}" />
</p:column>
</p:dataTable>
My doubt is default value ALL click and second time select any value return null or no data show in dataTable.
Since I don't know the scope of your Managed Bean: Try a scope longer than request (see PrimeFaces 5.1 User Documentation), and provide a value "filteredValue" for your table, like this:
<p:dataTable id="datalist" widgetVar="datalist" var="user"
value="#{beanList.userList}" filteredValue="#{beanList.filteredUserList}">
With that, you make sure to keep your filtered table/list in a field in your managed bean and the contents won't get lost.
Also, make sure your Managed Bean class is serializable (See this stackoverflow post)
my form looks like that:
<p:inplace>
<h:inputText id="description" value="#{cc.attrs.description}" />
</p:inplace>
When the user clicks into the Text of the p:inplace the inputText will be shown to edit the value.
How can I hide the inputText or the p:inplace when the user clicks somewhere else or the control it self lose the focus.
Thanks.
Use the blur event over the inputText, passing an id value to it:
<p:inplace widgetVar="basic_#{cc.id}">
<p:inputText value="#{cc.attrs.description}" id="description">
<p:ajax event="blur" oncomplete="basic_#{cc.id}.hide();" />
</p:inputText>
</p:inplace>
I am working on a form which has two datatables. In the first datatable, I am displaying the radio buttons and checkboxes, whereas the second datatable contains
selectOneMenu(s). Value change listener has been implemented on the selectOneMenu and on value change, the subsequent fields gets populated based on the selection.
Everything works fine except that when I select the value from the dropdown, the checkbox and the radio button values are cleared.
f:ajax event="change" has been used for the change event on selectOneMenu. Looks like the whole page gets refreshed and the values are cleared.
I also tried using f:ajax by updating the id of the datatable in which the selectOneMenu is present.
<p:dataTable styleClass="borderless" id="inResultTable" var="result" value="#{RequestBean.fooFields}" rendered="#{not empty RequestBean.fooFields}">
<p:column style="width:150px;">
<f:facet name="header">
<h:outputText value=" " />
</f:facet>
<h:outputText value="#{msg[result.fldLabel]}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<ui:repeat value="#{RequestBean.fooFields}"
var="itm">
<h:selectOneMenu value="#{itm.indFieldValue}"
rendered="#{result.lvlid==itm.lvlid}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectOneMenu>
<h:selectOneRadio value="#{itm.indFieldValue}" rendered="#{result.lvlid==itm.lvlid and result.fldType=='radio'}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectOneRadio>
<h:selectManyCheckbox value="#{itm.indFieldCheckBox}" rendered="#{result.lvlid==itm.lvlid and result.fldType=='selectbox'}">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectManyCheckbox>
</ui:repeat>
</p:column>
</p:dataTable>
<p:dataTable styleClass="borderless"
id="resultTable" var="result"
value="#{RequestBean.depFields}">
<h:selectOneMenu value="#{RequestBean.field4Value}"
valueChangeListener="#{RequestBean.processValueChange4}"
rendered="#{result.lvlid=='5' and result.fldType=='selectbox'}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItem itemLabel="--Please Select--" itemValue="#{null}" />
<f:selectItems value="#{RequestBean[result.field]}" />
<f:ajax event="change" render="#form" />
</h:selectOneMenu>
...
...
</p:dataTable>
N.B: The requirement is such that the datatable with checkbox and radio buttons has to be placed at the top. IDs cannot be used for the selectOneMenu in the second table since I am
populating the selecOneMenu(s) dynamically based upon the entries in the database.
I know that this might be a simple issue but didn't have any luck with the info posted on most websites.
Any help would be appreciated.
Here's your <f:ajax>.
<f:ajax event="change" render="#form" />
You didn't specify the process attribute. So it defaults to #this, which means that only the current input component is processed during submit. However, you specified a render of the whole form. So the whole form will be refreshed. However, the other input components aren't been processed during submit. So their model values won't be updated, which means that during render response the initial values will be redisplayed instead of the submitted values, which are in your case apparently blank/null.
You've basically 2 options:
Process the whole form during submit.
<f:ajax process="#form" render="#form" />
Or, update only those components which really needs to be updated.
<f:ajax render="clientId1 clientId2 clientId3" />
In your particular case I think option 2 isn't viable, so option 1 is the best one. Please note that I omitted the event attribute. It defaults to change already.
Unrelated to the concrete problem, I'm not sure what you're all doing in your value change listener method, but I only want to note that most starters abuse it for the purpose of manipulating the model values and that it don't always work quite as expected (changed model values are not reflected at all). If this is true in your case, then you should actually be using <f:ajax listener> instead.
See also:
When to use valueChangeListener or f:ajax listener?
The main reason for the values of Check boxes & Radio buttons getting cleared after a value change listener could be that the model values are not updated.
Value change listeners are called before updating the model.
For these kind of issues, it is very important to have an understanding of the JSF lifecycle.
Please try following code in your value change listener and see.
public void valueChange(ValueChangeEvent event){
PhaseId phase = event.getPhaseId();
if (phase.equals(PhaseId.ANY_PHASE))
{
event.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
event.queue();
return;
}
if(!phase.equals(PhaseId.UPDATE_MODEL_VALUES))
{
return;
}
// Your code
}
I didn't try this code with your example. Please let me know with complete example source code if it is not working.
Thanks.
I have the following usage of the p:selectOneMenu:
<p:selectOneMenu id="selectField"
value="#{someBean.someField}"
converter="#{selectItemConverter}" var="x" editable="true">
<f:selectItems
value="#{selectItemsBean.getSelectItems(tab, field)}" var="si"
itemLabel="#{si.label}" itemValue="#{si}" />
<p:column>
<h:outputText value="#{si.label}" />
</p:column>
<p:column>
<h:graphicImage library="images" name="noway_16x16.png"
title="#{si.disabledReason}" rendered="#{si.disabled}" />
</p:column>
<p:ajax event="change" update="#form" partialSubmit="true" process="selectField" />
</p:selectOneMenu>
As you can see, I use custom content in combination with editable=true. When I submit the form, the Converter gets the label of a selected item as the value, not the actual value. In the HTML page, the values are correct, e.g. <option value="C">C-style mounting</option>. With editable=false, the correct value (e.g. C is sent to the converter, with editable=true the converter retrieves C-style mounting.
What I want is that the user can either select one of the pre-defined items in the list and the server submits that value of the item OR the user enters something and that is submitted as value. But the current behavior is a bit strange - or am I just wanting too much?
My requirement is like this: I am having a text input and whenever a value change event occurs, a select many list box has to be populated. If there is no matching records found, then a text input has to appear instead of a select many list box.
<h:column>
<h:selectManyListbox size="3" value="#{hostInfoBean.gateKeeperendPointReference}" rendered="#{hostInfoBean.selectManyRendered}" id="gateKeeperendPointReference">
<f:selectItems value="#{hostInfoBean.gateKeeperendPointReferenceItems}" />
</h:selectManyListbox>
<h:inputText id="gateKeeperendPointReferenceText" size="30" rendered="#{!hostInfoBean.selectManyRendered}">
</h:inputText>
</h:column>
Also I am using a4j for the value change listener,
<a4j:support event="onchange" reRender="hostInfo:gateKeeperendPointReference" focus="GFacPath"
ajaxSingle="true" />
'selectManyRendered' is a boolean value which I am determining in the JAVA bean. The program works only for the default value of the boolean variable. If the boolean value is changed during runtime, then the toggle between the visibility of selectManyListbox and inputText is not working. Please help to fix this. Am i missing something?
regards,
Suresh
If the "rendered" attribute resolves to false, then the component isn't in your tree and can't be found as a "rerender" target. When you have components that are rendered conditionally you want to wrap them in a component that is always available as a target, like so:
<h:inputText value="#{myBean.text}" >
<a4j:support event="onkeyup" reRender="listZone" ajaxSingle="true" />
</h:inputText>
<h:panelGroup id="listZone">
<h:selectManyListbox value="#{myBean.list}" rendered="#{myBean.renderList}" >
<f:selectItems value="#{myBean.listItems}" />
</h:selectManyListbox>
<h:inputText size="30" rendered="#{!myBean.renderList}/>
<h:panelGroup id="listZone">
