hi,
thanks for your answer.
how can I build a ognl variable dynamic? Example:
I have an iteration with different url-definitions, because
I need always another parameter (index):
<s:iterator value="myList" id="list" status="stat">
...
<s:url id="myMethod%{#stat.index}"
action="test_myMethod.action">
<s:param name="myParam" value="%{#stat.index}"/>
</s:url>
<s:autocompleter ...
href="%{myMethod%{#stat.index}}"/> <--- I need
here: %{myMethod0}, %{myMethod1}, ..., but it wasn't evaluated
</s:iterator>
Has someone an idea?
Firstly, it's not valid to nest OGNL expression
(%{...%{...}}) but you
can get the result you want something like this (untested):
href="%{'myMethod'+#stat.index}"
This may also work:
href="myMethod%{#stat.index}"
However, based on the code you posted, I suspect this isn't what you
want; aren't you trying to set the autocompleter's href to
the URL you
built with s:url above? In that case, just simplify:
<s:iterator ...>
<s:url id="url" ...>
<s:autocompleter href="%{#url}" ...
You don't need the identifier to be dynamic.
In my opinion I need the indifier. I have 2 or more (dynamic) autocompleter,
and the first autocompleter refreshs the second, the second and so one. I have
the same action for the refresh, but I need the index of the autcompleter,
which sends the notfiyTopic. So I need a dynamic build url id, because there is
different parameter for it. f.e.:
<s:url id="refresh0" ...>
<s:param name="myParam" value="0"/>
</s:url>
<s:autocompleter href="refresh0" ...
<s:url id="refresh1" ...>
<s:param name="myParam" value="1"/>
</s:url>
<s:autocompleter href="refresh0" ...
....
<s:url id="refreshX" ...>
<s:param name="myParam" value="X"/>
</s:url>
<s:autocompleter href="refreshX" ...
I guess I just don't understand your question. You'd get the same result
from the above if each s:url tag used the same id value, as in:
<s:url id="href" ...><s:param name="myParam" value="0"/></s:url>
<s:autocompleter href="%{#href}" .../>
<s:url id="href" ...><s:param name="myParam" value="1"/></s:url>
<s:autocompleter href="%{#href}" .../>
There's still no need for the id attribute to have a dynamic value.
