dataFilterSlider

[puh]

Hello!

I have created a dataTable and want to use a dataFilterSlider with this table. But I can´t understand the descritption in the developer guide, how to use the Slider. I find it very complicated. Could please someone send me an example of a simple dataFilterSlider. With jsp and java pages.

Thank you!!

Yes I have already explored this, but know I have the following mistake:

org.apache.jasper.JasperException: org.richfaces.component.EnclosingFormRequiredException: class org.richfaces.component.html.HtmlDataFilterSlider (id="slider_1") did not find parent form.

root cause

And here is my jsp-code:

</a4j:outputPanel>

</rich:dataTable>


</f:view>

Do you know, what to do?

Thank you!!

Data Filter Slider as any component that send ajax or non-ajax reuest requires form around. So wrap your table and slider with the form element.

[puh]

Yes I have seen this! Sorry!

But know the slider slides, but he doesn´t change the dataTable. If I change the slider value I get a NullPointerEcxeption. It seems, that the slider doesn`t get the information, what he has to slide.

Perhabs you know, what I am making wrong??
Here is the code of my jsp:

<a4j:form id="form1" reRender="list-body" ajaxSubmit="true" ignoreDupResponses="true" requestDelay="100">
<a4j:region id="stat1">
<a4j:outputPanel id="slider-body">
<rich:dataFilterSlider
for="scoreIndex"
forValRef="suggestionBox.result"
filterBy="getPmid"
manualInput="true"
onSlide="true"
onChange="true"
storeResults="true"
trackStyleClass="track"
width="400px"
styleClass="slider-container"
rangeStyleClass="range"
trailer="true"
trailerStyleClass="trailer"
handleStyleClass="handle"
startRange="1000000"
endRange="100000000"
increment="1000000"
handleValue="1"
id="slider_1" >
</rich:dataFilterSlider>
</a4j:outputPanel>

<a4j:outputPanel id="list-body">
<rich:dataTable id="scoreIndex" style="width: 100%"
styleClass="standardTable"
headerClass="standardTable_Header"
var="table" value="#{suggestionBox.result}" >
<h:column>
<f:facet name="header">
<h:outputText value="TITLE" />
</f:facet>
<h:outputText value="#{table.title}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="PMID" />
</f:facet>
<h:outputText value="#{table.pmid}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="SCORE" />
</f:facet>
<h:outputText value="#{table.score}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="SOURCE" />
</f:facet>

Data Filter Slider - ajaxed out of the box. remove ajaxSubmit from the form element

[ilya_shaikovsky]

but it mustn't be the reason. what about the exception. Paste it please.

[puh]

The mistake is gone now. Thank you. But the slider doesn`t change any value inside my table. Do you know why?? Do I have to write some code into my bean??

[ilya_shaikovsky]

ok. The last question I think about your environment. (JSF and RF versions)

[puh]

I use richfaces 3.0 and ajax4jsf1.1.0

But do you think, that I have to fill in something in my bean, that is missing know to refer to the column I want to change?

[ilya_shaikovsky]

Please make an update to 3.0.1 and 1.1.1 or 3.0.2 and 1.1.2 SNAPSHOTS. Release version was consists numerous bugs fixed later.

[puh]

I have downloaded ajax4jsf the latest version. Where can I download the SNAPSHOTS?? I am too blind to find it.

[puh]

With the new ajax4jsf it doesn`t work. Perhaps with the new SNAPSHOTS, but where to download? Do you think that there is something wrong in my code? Could you please take a look at it.

[puh]

Oh, I think that I have found it. Now I have Snapshots 3.0.1 and ajax4jsf the latest version. But it doesn`t work. Help Please!
