reRender problem with datascroller

[orribl]

Hi,

I have a problem getting my datascroller work properly.

I have a form with some fields on the top. After the fields are filled the dataTable update ( and filled ), also the dataScroller is part of the reRender-attribute.
I have a button with which contains the reRender attribute and which is responsible for the updating.
Here some code snippets:

<h:form >
...
 <h:inputText id="filiale" value="#{sessionBackingBean.currentFiliale}" required="true" maxlength="4" size="4"/>
 ...
 <a4j:commandButton id="showItems" value="#{msg.show_items}" action="#{sessionBackingBean.showMseItems}" reRender="mseItems,dsMseItems"/>

 <rich:datascroller id="dsMseItems" for="mseItems" maxPages="20" />

 <rich:dataTable rows="10" id="mseItems" value="#{sessionBackingBean.mseItems}" var="item">
 ...
 </rich:dataTable>
</h:form>

The strange thing is that after clicking the command button the dataTable is filled correctly, but the datascroller still shows the old state.
When I click the button again also the datascroller is shown correctly.

Does anybody has an idea why this happens and what I can do...?

Thanks in advance...

probably, it is because of the form validation failed due the inputText validators. Does it make difference if you inputText is not empty?

Hi,
I found a (unsatisfactory) solution:
When I place the datascroller after the dataTable

<rich:datascroller id="dsMseItems" for="mseItems" maxPages="20" />
<rich:dataTable rows="10" id="mseItems" value="#{sessionBackingBean.mseItems}" var="item">
...
</rich:dataTable>

it works as expected. Is it possible that the datascroller gets data from the rendered dataTable?
Does anybody know if there's a way to place the dataScroller before the dataTable...?

[orribl]

Of course I mean

<rich:dataTable rows="10" id="mseItems" value="#{sessionBackingBean.mseItems}" var="item">
...
</rich:dataTable>
<rich:datascroller id="dsMseItems" for="mseItems" maxPages="20" />

;)

Oh, OK. It looks like you use JSF 1.1 . If so, it is very famous problem of it.

Hi,

You're right, I'm using MyFaces 1.5 (which implementes the jsj1.1 specification).
Do you know a way to solve the problem with this implementation?

I've wrapped your

<rich:datascroller id="dsMseItems" for="mseItems" maxPages="20" />
<rich:dataTable rows="10" id="mseItems" value="#{sessionBackingBean.mseItems}" var="item">
...
</rich:dataTable>

with a4j:outputPanel component and it starts works as expected.

Hi ilya_shaikovsky,

that doesn't work for me, do you also work with myfaces 1.5 (and with the 1.1. jsf implementation)?

So my test code:

<h:form id="form">
 <h:inputText value="#{capitalsBean.rows}" required="true"
 maxlength="4" size="4" id="textfield">
 </h:inputText>
 <a4j:commandButton id="showItems" value="add/remove rows"
 reRender="table, scroller" />
 <a4j:outputPanel>
 <rich:datascroller id="scroller" for="table" maxPages="20" />
 <rich:dataTable rows="#{capitalsBean.rows}" id="table"
 value="#{capitalsBean.capitals}" var="cap">
 <rich:column>
 <h:outputText value="#{cap.name}"></h:outputText>
 </rich:column>
 <rich:column>
 <h:outputText value="#{cap.state}"></h:outputText>
 </rich:column>
 </rich:dataTable>
 </a4j:outputPanel>
 </h:form>

So In my code I'm changing the number of rows. And the scrioller updates successfully for me.

My Environment:
MyFaces Implementation-Version: 1.1.5
No facelets. (My be you've uses?)
Tomcat 5.5.17
Rich Faces and ajax4jsf 3.0.2 and 1.1.2 SNAPSHOTS.
