Essentially I have the following in the intake.xml:
<group name="ForwardAdd" key="mforwardadd">
<field name="Add" key="add" type="String">
<rule name="maxLength" value="255">TEXT.std_field_long_error</rule>
<rule name="mask"
value="^.+@[A-Za-z0-9\-]+\.[A-Za-z0-9\-\.]+$">TEXT.illegal_email_address</rule>
</field>
</group>
The group and field are pretty standard. I have the following in the
velocity template:
#set ($fagroup = $intake.ForwardAdd.Default)
... later on ...
Add an email address:
<input type="text" name="$fagroup.Add.Key"
value="$!vcstr_tool.toHtml($!fagroup.Add.Value.toString())" size="25">
<input type="submit" name="eventSubmit_doAddforward"
value="Add">
<!-- This is the error message -->
<font size="1">
#if (!$fagroup.Add.isValid())
$!vcstr_tool.toHtml($i18n.get($fagroup.Add.Message))<br>
#end
</font>
The vcstr_tool is my custom thing that'll escape the html characters
from the given string.
In the handler code (an action):
public void doAddforward(RunData data, Context ctx)
{
IntakeTool intake = (IntakeTool)ctx.get("intake");
if (intake.isAllValid())
{
try
{
Group forwardAdd = intake.get("ForwardAdd",
IntakeTool.DEFAULT_KEY);
Field addField = forwardAdd.get("Add");
.... more stuff to use the addField here ...
}
catch (Exception e)
{
}
}
else
{
data.setMessage(
Localization.getString("TEXT.Invalid_input",
data.getRequest()));
return;
}
}
The problem is, if I put in a wrong value (that violates the regex, for
example) in the text box, the wrong value will disappear the next time
when I load the page, even though the correct error message is displayed.
When I stepped through the debugger I found that the value is gone
before the "IntakeTool intake = ..." line. I even traced to the init()
call of the IntakeTool and it seems like the value is gone after you
call init() of the tool. Is there anything I do wrong here?
On the side note, I have always had issue with Intake's handling of
empty strings. What I realize is, if you have an empty string in the
form, it won't get submitted (or the ParameterParser won't take it?? I
didn't do much investigation on this). As a result, the field
associated with the empty string will not appear in the group. However,
sometimes I REALLY want to have a field that sets to null or "". If I
use the mapToObject to map a certain field to an object, calling
setProperties() will not call "set" for the empty fields. Thus, the
internal state of the object would not change. Is there anything I can
do here?
