How to avoid duplicate id in component

[tmahesh1983]

Hi
I need to design datatable with dynamic number of columns, so i was try to design <rich:datatable> with <rich:columns> tag, that produces
javax.servlet.ServletException: javax.servlet.jsp.JspException: java.lang.IllegalStateException: Duplicate component id

I was come across multiple posts they suggest to avoid duplicate id exception assign id for every component. I have tried like that even problem comes. I have enclosed page code and stack trace with this post.

<rich:dataTable id="sampleDataTable" value="#{Sample.dataList}" var="record">
<f:facet name="header">
<rich:columnGroup id="headerColumnGroup">
<rich:column id="nameColumnHeader" rowspan="2">
<h:outputText value="Name"/>
</rich:column>
<rich:column id="itemsColumnHeader" colspan="3">
<h:outputText value="Items" />
</rich:column>
<rich:column id="firstItemHeader" breakBefore="true">
<h:outputText value="Item-1" />
</rich:column>
<rich:columns id="itemColumns" columns="2">
<h:outputText value="Item"/>
</rich:columns>
</rich:columnGroup>
</f:facet>
<rich:column id="nameColumn">
<h:outputText value="#{record.name}"/>
</rich:column>
<rich:columns id="selectItem" columns="3">
<h:selectBooleanCheckbox id="categoryCheckBox"/>
</rich:columns>
</rich:dataTable>

Try to set only the IDs you need for referencing. Delete all others.

[tmahesh1983]

i was try like that...same problem occurs

[fmarwede]

Here are some more suggestions:

1.) Search in this forum, because we had this issues a lot of times in the past.
2.) If possible try it without myfaces.
3.) Post your environment data so it is easier for a RF team member to post some help.

i remember i had this issue before but sorry can't remember what it was...

just looking at my code, it's like yours but with a columnGroup more :

<rich:dataTable id="sampleDataTable" value="#{Sample.dataList}" var="record">
 <f:facet name="header">
 <rich:columnGroup id="headerColumnGroup">
 <rich:column id="nameColumnHeader" rowspan="2">
 <h:outputText value="Name"/>
 </rich:column>
 <rich:column id="itemsColumnHeader" colspan="3">
 <h:outputText value="Items" />
 </rich:column>
 <rich:column id="firstItemHeader" breakBefore="true">
 <h:outputText value="Item-1" />
 </rich:column>
 <rich:columns id="itemColumns" columns="2">
 <h:outputText value="Item"/>
 </rich:columns>
 </rich:columnGroup>
 </f:facet>
 <rich:columnGroup>
 <rich:column id="nameColumn">
 <h:outputText value="#{record.name}"/>
 </rich:column>
 <rich:columns id="selectItem" columns="3">
 <h:selectBooleanCheckbox id="categoryCheckBox"/>
 </rich:columns>
 </rich:columnGroup>
</rich:dataTable>

Hi

I try with <rich:columnGroup>, still same problem continues. whenever i remove one <rich:columns> from data table it works. for example the following code works well. but i don't want like this. I want to add column dynamically.


<rich:dataTable id="sampleDataTable" value="#{Sample.dataList}" var="record">
<f:facet name="header">
<rich:columnGroup id="headerColumnGroup">
<rich:column id="nameColumnHeader" rowspan="2">
<h:outputText value="Name"/>
</rich:column>
<rich:column id="itemsColumnHeader" colspan="3">
<h:outputText value="Items" />
</rich:column>
<rich:column id="firstItemHeader" breakBefore="true">
<h:outputText value="Item-1" />
</rich:column>
<rich:column id="secondItemHeader">
<h:outputText value="Item-2"/>
</rich:column>
<rich:column id="thirdItemHeader">
<h:outputText value="Item-3"/>
</rich:column>
</rich:columnGroup>
</f:facet>
<rich:column id="nameColumn">
<h:outputText value="#{record.name}"/>
</rich:column>
<rich:columns id="selectItem" columns="3">
<h:selectBooleanCheckbox id="categoryCheckBox"/>
</rich:columns>
</rich:dataTable>

[ronanker]

your right.

The following code should work:

<rich:dataTable id="sampleDataTable" value="#{Sample.dataList}" var="record">
 <f:facet name="header">
 <f:subview id="header">
 <rich:columns ...
 </f:subview>
 </f:facet>
 <rich:columns ...

Please try 3.3.1-snapshot

Hi,

I am wondering about the hierarchy of the assigned component ids.

Assuming a component tree like this

+id: j_id_id18
 type: org.ajax4jsf.component.AjaxViewRoot@162190
 +id: sampleDataTable
 type: org.richfaces.component.html.HtmlDataTable@f5a010
 +id: ColGroup_1
 type: org.richfaces.component.html.HtmlColumnGroup@1dfb87a
 +id: rf0
 type: org.richfaces.component.html.HtmlColumn@c8756c
 +id: rf1
 type: org.richfaces.component.html.HtmlColumn@0982fe
 +id: ColGroup_2
 type: org.richfaces.component.html.HtmlColumnGroup@1dfb87a
 +id: rf0
 type: org.richfaces.component.html.HtmlColumn@c8756c
 +id: rf1
 type: org.richfaces.component.html.HtmlColumn@0982fe

Shouldn't the full component ids be

'sampleDataTable:ColGroup_1:rf0'

and

'sampleDataTable:ColGroup_2:rf0'

according to the hierarchy given by the indentation of the component tree?


Because the exception leaves out the component group id?

IllegalStateException: Duplicate component id: 'sampleForm:sampleDataTable:rf0'

Why is ComponentGroup id ignored?

Actually "rf0" is not a unique id anyway, so why does RF not assign unique ids in the first place when user has not assigned explicit ids?

Thanks for your help.

3.3.1 snapshot did the trick, at least in my case.

Thanks a lot, great work!
