serviceContext.getAssetTagNames() returns null

[Habib Zare, modifié il y a 11 années.]

I have created Book entity. i want to add tags and category for every book like BlogsEntry.

in the method of BlogsEntry`s service :

BlogsEntryLocalServiceImpl.addEntry(..., ServiceContext){

.....
....
.....

// Asset  
updateAsset( userId, entry, serviceContext.getAssetCategoryIds(), serviceContext.getAssetTagNames(), serviceContext.getAssetLinkEntryIds());

....
}

the serviceContext.getAssetTagNames() returns the string array of tags.

I have created the method addBook :

BookLocalServiceImpl.addBook(..., ServiceContext) {
.............
..........
//asset
   updateAsset(userId, book, serviceContext.getAssetCategoryIds(), serviceContext.getAssetTagNames());


return book;
}

in this method serviceContext.getAssetTagNames() returns null;

why?

in the action i do (like the BlogsEntry )

ServiceContext serviceContext = ServiceContextFactory.getInstance(Book.class.getName(), actionRequest);
// call the service method.

why i cannot get serviceContext.getAssetTagNames()?(or serviceContext.getAssetCategoryIds())

Hi,All. any idea?

How did you add categories/tags in the JSP?

This is how blogs does it:

	<liferay-ui:asset-categories-error />

	<liferay-ui:asset-tags-error />

	<aui:model-context bean="<%= entry %>" model="<%= BlogsEntry.class %>" />
...
				<aui:input name="categories" type="assetCategories" />

				<aui:input name="tags" type="assetTags" />

Thanks Amos Fong.

I did the same way.

I think the problem is in

ServiceContextFactory.getInstance(Book.class.getName(), actionRequest);

I solved my problem by doing:

long[] assetCategoryIds = StringUtil.split(ParamUtil.getString(uploadRequest, "assetCategoryIds"), 0L);
String[] assetTagNames = StringUtil.split(ParamUtil.getString(uploadRequest, "assetTagNames"));

serviceContext.setAssetCategoryIds(assetCategoryIds);
serviceContext.setAssetTagNames(assetTagNames);

I think this is not good way but it works.
