Hi,
if you want to display a HTML select where the user should see a list of
categories try with:
<db:select fieldName="request_category">
<db:tableData
name="select_categ"
foreignTable="categories"
visibleField="category"
storeField="category"
disableCache="true" />
</db:select>
I use disableCache if I have different controls with the same datasource on the
same page.
You have always to embed <tableData> <queryData> <staticData> in a "embedding
data tags"... select, searchCombo, comboBox, dataLabel, etc.
Cheers
