Dynamic columns visibility
vali_iva May 18, 2011 8:53 AMHi, I'm trying to toogle the visibility of column from an extendedDataTable with a checkbox.
When I check the box, the table gets reRendered, the value in bean is changed but the column does't dis/appear.
I can't figgured it aout what is wrong.
Here is the code snippet:
<rich:extendedDataTable id="indexes" value="#{asetsScreener.indexes}" var="index" height="400px" width="900px" title="Indexes" selectionMode="none"> <rich:column width="40px"> <a4j:facet name="header"> Index </a4j:facet> <h:outputText value="#{index.indicator}"/> </rich:column> <rich:column width="40px"> <a4j:facet name="header"> Show </a4j:facet> <h:selectBooleanCheckbox value="#{index.shown}"> <a4j:support event="onclick" reRender="compsTable, testtest"/> </h:selectBooleanCheckbox> </rich:column> <rich:column width="250px" style="text-align:right;"> <a4j:facet name="header"> Min Value </a4j:facet> <rich:inputNumberSlider id="minRangeSlider" value="#{index.minRange}" minValue="#{index.min}" maxValue="#{index.max}" onmouseup="slide(this)" oninputkeyup="slide(this)" showArrows="false" inputPosition="right"> <a4j:support event="onchange" reRender="minRangeSlider"/> </rich:inputNumberSlider> </rich:column> </rich:extendedDataTable>
Here I have a list of checkboxes and sliders. And for every checkbox that is checked, a column should be shown in the next table:
<a4j:outputPanel id="companies" ajaxRendered="true"> <rich:extendedDataTable value="#{asetsScreener.comps}" id="compsTable" var="comp" selectionMode="none" height="210px" > <rich:column visible="true"> <f:facet name="header"> <h:outputText value="Company"/> </f:facet> <h:outputText value="#{comp['CompanyName']}"/> </rich:column> <rich:columns value="#{asetsScreener.indexes}" var="column" visible="#{column.shown}"> <f:facet name="header"> <h:outputText value="#{column.indicator}"/> </f:facet> <h:outputText value="#{comp[column.indicator]}"/> </rich:columns> </rich:extendedDataTable> <h:outputText value="#{asetsScreener.indexes[1].shown}" id="testtest"/> </a4j:outputPanel>
If I check some boxes and hit refresh, the right columns are diplayed. But I don't want it on page refresh, I want it on checkbox event.
If I change the value of the inputNumberSlider, then all the columns are made visible although no checkbox is checked.
It has a wired behaviour.
I would be gratefull if you guys could help me with this.
Thanks.
