other components inside Dynamic component?
Hi all,
I have a question regarding Dynamic component. I use it for keeping parts of tml code in the database. It renders insertions used for functions calling such us ${someFunc('someParam')} , but it does not render any tapestry tags correctly. It just omits "t" prefix instead and adds xmlns attribute. For example, the following code
<t:if test="true">asdf</t:if>
Rendered to:
<if test="true" xmlns="http://tapestry.apache.org/schema/tapestry_5_3.xsd">asdf</if>
What are the suggestions? Are there any good examples of code in the net?
Here is My code:
public class TrackerDynamic extends Tracker {
@Property
private DynamicTemplate dynamicTemplate;
@InjectService("DynamicTemplateParser")
private DynamicTemplateParser dynamicTemplateParser;
private String getTemplateString() {
StringBuilder sb = new StringBuilder(
"<div id=\"trackerDynamic\" xmlns:t=\"http://tapestry.apache.org/schema/tapestry_5_3.xsd\" xmlns:p=\"tapestry:parameter\">\n");
sb.append(...//some code for inserting custom data from database
sb.append("</div>");
return sb.toString();
}
@Override
void beginRender() {
try {
dynamicTemplate = dynamicTemplateParser.parseTemplate(
new StringResource(getTemplateString())
);
} catch (Exception ex) {
}
}
}
TrackerDynamic.tml:
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd" xmlns:p="tapestry:parameter">
<t:Dynamic template="prop:dynamicTemplate"></t:Dynamic>
</t:container>
StringResource.java:
public class StringResource implements Resource {
private String tml;
public StringResource(String tml) {
this.tml = tml;
}
@Override
public boolean exists() {
return false;
}
@Override
public InputStream openStream() throws IOException {
return new ByteArrayInputStream(tml.getBytes("UTF-8"));
}
@Override
public URL toURL() {
return null;
}
@Override
public Resource forLocale(Locale locale) {
return null;
}
@Override
public Resource forFile(String relativePath) {
return null;
}
@Override
public Resource withExtension(String extension) {
return null;
}
@Override
public String getFolder() {
return null;
}
@Override
public String getFile() {
return null;
}
@Override
public String getPath() {
return null;
}
}

I doubt that'll do anything since the field is a per thread value.
I meant to add an appropriate hashCode() an equals() method to
StringResource. Or perhaps override the DynamicTemplateParser service with
a non caching version.

No, the field is still a Per-Thread value. It will be null for the next
request. You've just made it so that the field will be calculated at most
once per request.

Changed to this. Is it ok now?
...
private DynamicTemplate dynamicTemplate;
public String getLastModificationDate() {
return partnerCodeService.getLastModificationDate().toString();
}
@Cached(watch = "LastModificationDate")
public DynamicTemplate getDynamicTemplate() {
if (dynamicTemplate == null) {
dynamicTemplate = dynamicTemplateParser.parseTemplate(
new StringResource(getTemplateString()));
}
return dynamicTemplate;
}

So, if DynamicTemplateParser has a cache by Resource, how is it identifying the resource? Or, just how to avoid the problem?
By the way, now my code looks as following, but not sure it changes the cache behavior:
public class TrackerDynamic extends Tracker {
private DynamicTemplate dynamicTemplate;
public DynamicTemplate getDynamicTemplate() {
if (dynamicTemplate == null) {
dynamicTemplate = dynamicTemplateParser.parseTemplate(
new StringResource(getTemplateString()));
}
return dynamicTemplate;
}
...
}

Not sure how to fix your issue but I spot another issue.
DynamicTemplateParser has a cache by Resource. It looks like you add to the cache for every render. It's only a question of time before you hit out of memory errors.

DynamicTemplateParser has a cache by Resource. It looks like you add to the
