Problem with inputNumber and EL #{p:component('element_id')}

fischer1983 · 19 Apr 2016, 13:35

Hi ,

We are using the inputNumber component PF extensions. It serves us perfectly. But we are going through the following situation:
We created a composite component, and within it we have a inputNumber. To reference it by id in XHTML are using the EL # {p:component ( '<element_id>')}.

Code: Select all


 <teiLabel:Label for="#{p:component(cc.attrs.idInputNumberLabelled)}"/>

 ...more code

 <p:inputNumber id="#{cc.attrs.idInputNumberLabelled}" value="0.0"/>

To do this way, the following exception is raised below:

Code: Select all

08: 19: 03.631 ERROR [io.undertow.request] (default task 126) UT005023: Exception handling request to /tei-ambiente/pages/usuario/usuario.xhtml: javax.servlet.ServletException: / WEB-INF / classes /META-INF/resources/componentes/form/label/labelComum.xhtml @ 32.49 test = "# {empty cc.attrs.for!}" javax.el.ELException: / WEB-INF / classes / META-INF /resources/componentes/form/input/number/inputNumberLabelled.xhtml @ 207.69 labelFor = "# {p: component (cc.attrs.idInputNumberLabelled)}": Problems calling function 'p: component'

We found that inputNumber renders a span with two inputs within (one hidden), their ids are assigned '_input' and '_hinput'. We do not know if this is related to the exception.

If a friend to help we would be grateful.

Thanks for listening

not sure what teiLabel:labelFor is, but if you use p:outputLabel, the following should work:

<p:outputLabel for="#{cc.attrs.idInputNumberLabelled}"/>

i would not use p:component for compoent references, as it starts the search from the root and not the "current component" where it's used.

Hello Thomas , grateful for the attention.

When I pasted the code here just not checking what was wrong the code <teiLabel:Label for="# {p:component(cc.attrs.idInputNumberLabelled)}"/> . Already corrected in the post above . If this tag is a composite component that has within it an <h:outputText> .

I conducted the following test . Inserted a p:outputLabel and p:inputText , as follows:

Code: Select all

  <p:outputLabel for="text_input" value="text_input"/>                   
  <p:inputText id="text_input"/>

This works perfectly. With the attribute "for" filled with the id of the related input by clicking on the label the input receives focus.

Below I do another test with the inputNumber element PF Extensions , as follows:

Code: Select all

  <p:outputLabel for="number_input" value="number_input"/>
  <pe:inputNumber id="number_input"/>

But when I render the inputNumber , occurs the following exception:

Code: Select all

If I use a h:outputText not the exception occurs , but when you click the label the input that is stated in their "for" attribute does not get the focus.

Thanks for attention.

make you sure you use the newest PFExtensions version. Otherwhise to try to build PF 6.0 from source, inputNumber was moved to PF directly.

I really had not verified that there was a new version been released, was with 3.2.0 . Even in version 4.0.0 has another improvement that I was waiting for this component.

Danke!
