So say I have a component that wraps a grid like:
SomeGrid.tml
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter">
<t:form>
<t:grid/>
</form>
</t:container>
SomeGrid.java
@SuppressWarnings("unused")
@Component(parameters={"overrides=prop:overrides", ...other params...})
private Grid grid;
@Parameter(value = "this", allowNull = false)
@Property(write = false)
private PropertyOverrides overrides;
A component that contains SomeGrid.tml and it overrides a column:
SomeGridContainer.tml
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter">
<t:someGrid>
<p:nameCell>test Some Grid Container</p:nameCell>
</t:someGrid>
</t:container>
SomeGridContainer.java
@SuppressWarnings("unused")
@Component(parameters={"overrides=prop:overrides", ...other params...})
private SomeGrid grid;
@Parameter(value = "this", allowNull = false)
@Property(write = false)
private PropertyOverrides overrides;
A page that contains SomeGridContainer
MyPage.tml
<t:someGridContainer>
<p:nameCell>test Page</p:nameCell>
</t:someGridContainer>
</t:container>
In SomeGrid and SomeGridContainer I have @SupportsInformalParameters and
inject ComponentResources and pass in the overrides.
in the Name column, "test Page" always shows. I then tried and removed
p:nameCell from myPage.tml and column displayed whatever was in the name
property of the current row. So it seems p:nameCell in SomeGridContainer is
always ignored. Is this the right behavior? It would be nice if I can get
around this since I can define column parameters in the container component
and not have to redefine them in every page I use. And for cases where I
want to override the ones in the container I can define them in the page.
Anyways interesting behavior.
