[Tobago] dynamic panels in tc:sheet
Hi all.
I would like to create a tc:sheet as follows:
In want add a panel to a Colmun, which has many command elements for
each row in the sheet.
I have written a method to create a panel for the row object of the
sheet, but
i need help to bind the method with jstl or java to the panel.
JSP:
<tc:sheet value="#{controller.objects}" id="objectSheet" var="object"
>
<tc:column id="col1" sortable="false">
<tc:out value="#{object.attribut}" id="t_out" />
</tc:column>
<tc:column id="col2" sortable="false">
<tc:panel binding="#{.....}" id="t_panel" />
</tc:column>
</tc:sheet>
Controller:
public UIComponent createPanel(Object obj) {
FacesContext facesContext = FacesContext.getCurrentInstance();
UIPanel panel = (UIPanel)
ComponentUtil.createComponent(facesContext,
UIPanel.COMPONENT_TYPE,
TobagoConstants.RENDERER_TYPE_PANEL,
"img_panel");
for (int i = 0; i < ob.getImgObjects.size(); i++) {
ImgObj img = ob.getImgObjects.get(i);
UILinkCommand linkCommand = (UILinkCommand)
ComponentUtil.createComponent(facesContext,
UILinkCommand.COMPONENT_TYPE,
TobagoConstants.RENDERER_TYPE_LINK,
"link" + i);
ComponentUtil.setStringProperty(linkCommand,
TobagoConstants.ATTR_IMAGE, img.getIconUrl());
panel.getChildren().add(linkCommand);
}
return panel;
}
Any suggestions?
Regards
Hani

Hi Volker,
I don`t get it.
Please look at the picture in the attachment.
The List of the figures for each row object is dynamic and different.
Is that possible in tobago? How can i programe it?
Thank You

Hi Hani,
you can't have different UIComponents in the rows.
There is only one set of components which is rendered multiple times
for the rows, if you need different row contents you need to add all
components and hide some of them via rendered attribute.

Volker

Thank you Volker,
The updating of the panel must be dependent on the row object of the sheet,
that means the content of the panel for each row is different.
How can i tell the set-method for the panel the row object.
How can i reach that?
Regards,
Hani

TobagoConstants.RENDERER_TYPE_LINK,
"link" + i);

TobagoConstants.ATTR_IMAGE, img.getIconUrl());
panel.getChildren().add(linkCommand);
}
}
In jsf the getter of the binding of a component is called once at
component creation at the first rendering of the view.
The setter is called if the getter returns null (with a UIComponent
instance created by the framework) and at every restoreView.
Your sould never store the component given by the setter somewhere, at
least not longer than request scope.
Hope this helps,

Volker
