LinkSubmit with parameters causes exception although it has validators attached
-------------------------------------------------------------------------------
Key: TAPESTRY-1240
URL: https://issues.apache.org/jira/browse/TAPESTRY-1240
Project: Tapestry
Issue Type: Bug
Components: Framework
Affects Versions: 4.1.1, 4.1, 4.1.2
Environment: last test was with Tapestry 4.1.2-20070121
Reporter: Kristian Marinkovic
A LinkSubmit component causes an exception if the bound listener requires one
or more parameters and
the values of the parameters binding are null. This behavior is correct as long
as the bound parameters
don't come from a TextField with a "required" validator.
Looking at the code below i would have expected that when the page is
submitted, the TextField component
gets validated before the LinkSubmit. If so Tapestry would report the
validation error and not the exception.
.page file
<component id="lnk_read" type="LinkSubmit">
<binding name="listener" value="listener:readGPList" />
<binding name="parameters" value="searchFieldValue" />
</component>
<component id="txtSearchField" type="TextField">
<binding name="value" value="searchFieldValue" />
<binding name="validators" value="validators:required" />
</component>
<property name="searchFieldValue" />
.java file
public void readGPList(String txtSearchField) {}
