Hey all,
I've recently been using T 5.3 for an internal site, and have run into a bit of
a snag when using a select component along with a zone and blocks to
conditionally render parts of a form. I'll include my code below, but first I'd
like to explain what I'm attempting to do, as well as what is going wrong.
Essentially, I populate a t:select component first from a list of pre-defined
values, then using the onValueChangedFrom() method, I get the value of the
currently selected item from t:select in order to conditionally render the next
part of my form. Each item in the select menu corresponds to a block, which is
then displayed within a zone that corresponds to the t:select component. This
all works fine, and is not the issue that I'm running into. The issue I do have
however, is when the value for select corresponds to a block with a TextArea
inside it, html comments appear within that area. Here is a snippet of code,
with (un)important bits and pieces redacted. The block labeled createBlock is
the one with a TextArea component within it.
Test.java
@Property
private UploadedFile upload;
@Property
private String createCSV;
@Property
private List<String> action;
@Component
private Form uploadForm;
@Inject
private Block editBlock, uploadBlock, createBlock, emptyBlock;
@InjectComponent
private Zone uploadZone;
public Object onActivate(){
if(!userSession.isAuthenticated())
return LoginPage.class;
action = Arrays.asList("Choose an option",
"Upload", "Create", "Edit");
return null;
}
public Object onValueChangedFromAction(String s){
if(s.equals("Upload")){
return
uploadBlock;
}else if(s.equals("Create")){
return
createBlock;
}else if(s.equals("Edit")){
return
editBlock;
}else
return
emptyBlock;
}
Test.tml
<html
t:type="layout"
t:pageName="Test"
t:pageTitle="Test"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd";>
<t:block t:id="emptyBlock">
<br/>
</t:block>
<t:block t:id="createBlock">
<table>
<tr>
<td class="name"><b>Write your own .csv here:</b> </td>
</tr>
<tr>
<td><t:TextArea t:id="createCSV" t:value="createCSV" rows="5"
></t:TextArea></td>
</tr>
</table>
</t:block>
<t:block t:id="uploadBlock">
<t:label for="upload">Upload file:</t:label>
<input t:type="upload" accept="text/csv"
t:id="upload" t:value="upload" validate="required"/>
</t:block>
<t:form t:id="uploadForm">
<t:errors/>
<t:label for="action">Create,
edit, or upload .csv?</t:label>
<t:select t:id="action"
model="action" t:zone="uploadZone" t:value="actionSelection"
t:blankOption="NEVER" validate="required"/>
<t:zone
t:id="uploadZone" id="uploadZone">
<t:if test="action">
</t:if>
</t:zone>
<br/>
<input type="submit" class="submitbutton"
value="${message:Test.button.submit}" style="vertical-align:middle;"/>
<t:actionlink t:id="cancel"
class="cancelbutton">${message:Test.button.cancel}</t:actionlink>
</t:form>
</html>
Below is an example of the comments that populate the TextArea upon switching
from another block, line 17 refers to this line:
<td><t:TextArea t:id="createCSV" t:value="createCSV" rows="5"></t:TextArea></td>
<!--BEGIN bulkimport/Test:createcsv$renderdisabled
(context:bulkimport/Test.tml, line 17)--><!--BEGIN
bulkimport/Test:createcsv$discardbody (context:bulkimport/Test.tml, line
17)--><!--END bulkimport/Test:createcsv$discardbody--><!--END
bulkimport/Test:createcsv$renderdisabled-->
Thanks in advance for all the help!
