"Extensible" combobox in struts?
Hello,
I need the functionality of an "Access-like" combobox which supports some basic <html:option> elements, but is extensible. So, if the user does not find the entry he needs, he can just type it in.
-- cut here --
<html:select property="job" styleClass="Pulldown" tabindex="1">
<html:options collection="jobs" property="job"/>
</html:select>
-- cut here --
This coding only allows to select one of the pre-defined entries..
Any idea how to extend this?
Thanks in advance,
Jan Niklaas Wechselberg

This sort of widget doesn't exist on HTML forms. You should add a text input to your page, and a "new" option.
Using javascript you can set this option on "onchange" event from text input and reset text if value selected in select
list differs from "new".

Hi you can have a page where the user can select existing option
and add a link to a page where the user can add a new option
item.
You got an ActionForm where you have a getOptions () and you
can make an helper call to populate a Collection of options.
Collection getOptions () {
options = helperGetOption.getOptions )
return options
}

Validate() method returns blank form
Posted by Richard Mixon <rn...@custco.biz>.
For some reason a validate that returns a non-empty ActionErrors object is
not re-displaying the form with the errors.
We have a simple validate method in our actionform. When the validate finds
an error it returns the ActionErrors object with 1 ActionError (debug
statements show that) just fine.
When we set log4j to trace Struts it seems to say the "failed" validation is
working and we should see the original form displayed with the errors:
11:26:06,712 DEBUG ClassGridForm:297 - adding error
org.apache.struts.action.ActionError@19bc716
11:26:06,712 DEBUG ClassGridForm:354 - return with errors 1
11:26:06,712 DEBUG RequestProcessor:967 - Validation sailed, returning to
'/WEB-INF/pages/classGrid.jsp'
11:26:06,712 DEBUG ActionFilter:211 - Return from chain.doFilter(request,
response).
Thanks in advance for any suggestions or ideas.
- Richard
PS: Here is the action mapping:
<action path="/operations/classGridAction"
type="com.ltoj.webapp.action.ClassGridAction"
name="classGridForm"
scope="session"
input="/WEB-INF/pages/classGrid.jsp"
parameter="method"
unknown="false"
validate="true">
<forward name="success"
path="/WEB-INF/pages/classGrid.jsp"
redirect="false"/>
<forward name="error"
path="/WEB-INF/pages/classGrid.jsp"
redirect="false"/>
</action>

Re: "Extensible" combobox in struts?

Html langugage does not allow users to type in the combo-boxes (to add
an item or to reduce the list by typing the first letters). Struts is
rendering pure HTML so Struts can't render what you need.
Only solution I can think of is an HTML input, with DHTML and layers. If
the field has the focus, a layer is displayed (its content can be generated
by an action), if the user types some letters, the layer is refreshed to
reduce the list and if the user leaves the field with a content not present
in the list, argument(s) are passed to the next action via hidden fields to
add it to the list for the next users. So I think you'd better search in
websites about DHTML and JavaScript...
