O, thank you, I see. I did some progress, but I have one more question. How
should parameters be passed to csv generator?
I describe the whole picture below.
I defined a new component-instance. It ties the usecase with the pipeline.
<component-instance logger="lenya.admin"
name="admin.logs.export" class="ksa.usecases.Logs">
<view uri="cocoon://modules/administration/auditlogs.csv"/>
</component-instance>
The pipeline in sitemap.xmap:
<map:pipeline pattern="auditlogs.csv">
<map:generate type="auditlogs" src="auditlogs"/>
<map:serialize type="text"/>
</map:pipeline>
So, it calls 'auditlogs' generator that is defined in root's sitemap.xmap:
<map:generator name="auditlogs" label="content,data"
logger="sitemap.generator.auditlogs" pool-grow="2" pool-max="16"
pool-min="2" src="ksa.generators.AuditLogsGenerator"/>
So, the question is how to pass parameters from web page to the generator?
Could someone give a piece of advice?
Maybe there can be another way. I would be glad to hear about it.
