Ted Husted commented on WW-1538:
--------------------------------
I'm trying to add a second file to the download example, but I don't understand
how the Action works.
public class FileDownloadAction implements Action {
public InputStream getImageStream() throws Exception {
return
ServletActionContext.getServletContext().getResourceAsStream("/images/struts.gif");
}
public String execute() throws Exception {
return SUCCESS;
}
}
Is there an interceptor that calls the getImgageStream method.
I tried to add a zip file download by parameterizing the resource path
('/images/struts.gif'), but it didn't look like the getImage method fired.

> Showcase Examples Broken
> ------------------------
>
> Key: WW-1538
> URL: https://issues.apache.org/struts/browse/WW-1538
> Project: Struts 2
> Issue Type: Bug
> Components: Actions
> Affects Versions: 2.0.2
> Reporter: Ted Husted
> Assigned To: Ted Husted
> Fix For: 2.0.3
>
>
> Tags / UI Tags / TimePicker
> * Is there a way to specify now? "Today" sets the value to midnight.
> * The DE and NL versions do not seem to be internationalized in any way.
> Validation / JavaScript
> * The JavaScript validation does not seem to be working at all.
> * The String Length validator field sees an empty string as a value and can
> prompt even when empty (the usage on Field Validator doesn't seem to have
> this problem).
> EXPERIMENTAL
> AJAX Example
> ajax/autocompleter/
> * org.apache.jasper.JasperException: /ajax/autocompleter/index.jsp(19,0)
> According to the TLD or the tag file, attribute list is mandatory for tag
> autocompleter
> ajax/remoteforms/
> * org.apache.jasper.JasperException: /ajax/remoteforms/index.jsp(62,4)
> Attribute afterLoading invalid for tag submit according to TLD
> ajax/widgets/
> * Dojo button bar is not loading.
> Chat
> * Initialization takes *much* longer.
> * Operations seem to return a blank screen at first, but sometimes work
> afterwards.
> * In 2.0.1, at seemingly arbitrary intervals, thows "There is no Action
> mapped for action name chat/ajax/usersAvailable." But otherwise seemed to
> work.
> Hangman / Ajax
> * Doesn't recongize win or loss.
> Validation/Ajax
> * The age ranger works, name doesn't, submit doesn't.
> DEFERRED
> See WW-1548
> Continuation - continuations/guess.action
> * pause doesn't pause and the example runs through all the guesses on the
> first execution
> See WW-1554
> Hangman
> * Ajax, Selected letters not displayed.
> See WW-1559
> Tags / UI Tags
> * The optiontransferselect control and tooltip features are raising the
> javascript error "Could not load 'dojo.event.connect'; last tried
> '__package__.js'" at dojo.js line 94 "
> See WW-1571
> Prefix example
> * redirect-action throws a null pointer exception
> See WW-1572 (Only a quirk)
> Store across request using MessageStoreInterceptor (Example)
> * The action values are not retained, which is confusing. S
> * Store-across values to go wih the messages would be nice.
> QUIRKS
> Ajax
> * ajax/remotelink/
> ** Update 'Div 1', use custom loading message
> ** A simple DIV that updates every 2 seconds, with indicator
> The update happens so fast that the "custom loading message" or "indicator"
> is not visible
> Crud
> * Editing an Skill Name creates a new Skill (is that the intention?)
> * Is there a delete? or is this a CRU example?
> FileUpload
> * Seems to upload "empty" files when box is left empty.
> Tags / UI Tags / Date Example - /tags/non-ui/date.jsp
> * View Sources doesn't work for Configuration or Java Action
> ** The configuration is in the default namespace, which might be confusing
> the tab code
> ** The Action is brought in by executeResult, which would be invisible to the
> Java Action tag
> Validation / Field Validators
> * Date validation message prompt to enter 01-01-1990 max 01-01-2000 but only
> accepts dd/mm/yyyy (slashes)
> File Download
> * The example presents the Struts logo which displays correctly, but perhaps
> a better choice would be a file that prompts a download.
> FIXED
> AJAX example / Remote Forms
> * The examples involving replacing content on the page are returning blank
> values: 2, 4, 5, 6.
> * Examples 1 and 3 seem fine.
> * /ajax/datepicker/
> ** The HTML source is littered with spurious table elements (<td>, <tr>) and
> redundant dojo.requires statements.
> Execute and Wait - wait/index.jsp
> * The first time I went through the examples, it seemed fine. But when I
> tried it again, the wait page didn't display.
> * Struts 2.0.1 has the same problem.
> FileUpload - fileupload/doUpload.action
> * Returns "File cannot be empty" even if file is selected
> Person Manager
> * Create returns: No result defined for action
> org.apache.struts2.showcase.person.NewPersonAction and result input
> * List returns: No result defined for action
> org.apache.struts2.showcase.person.ListPeopleAction and result success
> Tags/ Non UI Tags / If example (freemarker)
> * freemarker version doesn't wrap #26 through #33, they run together as a
> paragraph
> * (In 2.0.1, both versions ran everything together.)
> Tags/ UI Tags / Input Example (both) - tags/ui/example!input.action
> * birthday field missing and not linked to control
> * color blank, picture blank
> Tags / UI Tags/ Tree / Static
> * Debug messages from Dojo are printing: DEBUG: DEPRECATED:
> dojo.widget.Editor is replaced by dojo.widget.Editor2 -- will be removed in
> version: 0.5
> DEBUG: DEPRECATED: addParseTreeHandler . ParseTreeHandlers are now reserved
> for components. Any unfiltered DojoML tag without a ParseTreeHandler is
> assumed to be a widget -- will be removed in version: 0.5
> Token
> * All examples throw null pointer exception on submit
> Validation/quizAjax!input.action
> * Validation messages "stack up" on resubmit
> * Submit button is at top left rather than bottom right
> Conversion / Address
> * Submiting an address doesn't seem to do anything.
> Conversation / Java5 Enum
> * Selecting any combination of operations yields a blank screen.
> Invalid field value for field "selectedOperations".
> Tags / UI Tags
> * This datepicker is broken, but other examples seem OK (except WW-1559)
> Conversion
> * conversion/enterAddressesInfo.action
> ** Submitting an address returns a blank page
> * conversion/submitOperationEnumInfo.action
> ** Select an operation returns: Invalid field value for field
> "selectedOperations".
> ** Selecting no operation returns a blank page.
> Person Manager
> * The Other Skills comboox doesn't accept the selected item, and there is a
> bogus entry at the bottom of the list.
> Tags / UI Tags / Tree / Static | Dynamic
> * Debug messages from Dojo are printing: FATAL exception raised: Could not
> load 'struts.widget.DatePicker'; last tried '__package__.js'
> ** The DatePicker pages don't have this message.
