Hi all
Is any example on following?
he
I am trying to write a code, Listbox will fill with table data using annotation binding. In a listbox a column having a boolean type. user will check/uncheck serially or randomly. After finishing the user work user will click the button and the check /uncheck data will commited to table.
Something like this
<listbox model="@{model}">
<listhead>
<listheader label="Boolean column"/>
<listheader label="Other column"/>
</listheader>
<listitem self="@{each=v}">
<listcell><checkbox checked="@{v.<your boolean property>}"/></listcell>
<listcell label="@{v.someOtherProperty}"/>
</listitem>
</listbox>
And inside onClick event of button you retrieve modified objects from listbox's model and put them into db.
Thanks Arsen

Every time I get the "false" value of lm at Update_all()
Strange code
Boolean lm = Boolean.valueOf(usrmenulst.getModel().getElementAt(i).toString());
Boolean lm = ((UserMenu)usrmenulst.getModel().getElementAt(i)).getAssigned()
Thank you very much Arsen
it works after replacing following statement.
Thanks in advance
Listbox has model, it some kind of collection of elements which are shown on listbox.
here you assigning this collection to listbox. usrmenulst - listbox, usrmenulist - it's model. Names are very similar, so it's a little bit confusing. I suggest it's better to rename model variable.
<listbox id="usrmenulst" width="100%" model="@{usrmenulist}" >
<listitem id="liusrmenu" self="@{each='usrmenu'}" value="@{usrmenu}">
<listcell> <!-- no need for id attribute here -->
<checkbox checked="@{usrmenu.assigned}"/> <!-- no need for id attribute here -->
</listcell>
<listcell label="@{usrmenu.menu_name}"/>
<listcell label="@{usrmenu.menu_item_name}"/>
</listitem>
You can also read on this site lot of good tutorials and smalltalks about listmodel's and databinding.
Hope this helps.
