Very interesting and challenging question.
Yes :)
I suppose that these "dynamic" pieces have something in common (e.g. an id,
an URL of the picture). This data can be passed as an attribute. The rest,
i.e. the specialized links/operations that you do on each picture, should be
computed internally in each piece, is it right?
The forEach-Tag iterates over a set of instances of the class picture.
These Instances hold every information, that is needed to compute the
links etc., so the actual picture-instance in loop x is the only
information, which has to be passed to the called template.
So I think, the answer is jes.
If yes, list.jsp can be reused anywhere (I mean for any kind of picture
template), as long as you identify all the needed data that each piece
needs, and pass them always, even if they don't use it.
And how do I change the called template in the XML-definitions?
Do you suggest to define an additional attribute in the specialised
definition, which holds the path to the template and then inject that
attribute to the template-attribute of the <t:insertAttribute>-Tag?
[..]
I had expected, that the EL would behave in the same way it behaves, when
it is written in the<t:insertAttribute>-Tag like in your last mail...
No, in my example, the EL expression is evaluated then passed to the
attribute. In your example, the attribute is rendered and, when rendering,
the EL expression is evaluated (to nothing).
O.k.
I think, I got that now.
But in my view, it would be a really nice feature, if it would work how
I had it expected to. It would ease the understandig of how the
EL-Expressions in definitions work and it would hugely widen the
applicability of EL-Expressions in definitions.
I would like to try to implement that behaviour. But I don't know, if I
am able to find the right lines of code, to alter. So far, I debuged my
way into the class, that creates the TilesApplicationContext for the
evaluation of the expression. But I'm lost there - somwhere...
