AppendRVFFromStream showing errors

[martindholmes]

I'm attempting to do this:

I have a set of small RVF documents saved in TMemoryStreams. Each of these documents is complete, and works perfectly when I stream it into a TRichViewEdit.

I need to combine these documents together in order to save them out as a single XHTML document. To do this, I'm creating an offscreen TRichViewEdit, along with a TRVStyle, then appending each of the documents from their streams, using AppendRVSFromStream.

Each time I append a document, I'm getting an error, and RVFWarnings shows:

[rvfwConvUnknownStyles]

I'm setting:
RVFParaStylesReadMode := rvf_sInsertMerge;
RVFTextStylesReadMode := rvf_sInsertMerge;

and I know that the documents themselves are complete and functional, because when I load them into an onscreen TRichViewEdit using LoadRVFFromStream, they appear perfectly.

There must be something I'm missing here.

In case it helps, this is what one of the document streams looks like:

All help appreciated,

I confirm the problem in RVF insertion (not loading) methods when RVF file was saved with [rvfoUseStyleNames, rvfoSave***Styles] in RVFOptions (i.e. it contains collections of styles and style names are used instead of style indices), and inserted with [rvfoLoad***Styles] in RVFOptions (i.e. collections of styles in these files are not ignored).
It will be fixed in the next update.

Notes:
1) As for me, saving with [rvfoUseStyleNames, rvfoSave***Styles] makes no sense. If collections of styles are saved in RVF file, why not to use indices to access them? Using style names makes sense if collections of styles are not saved in the same file.

2) If you still want to use these options, assign True to RichViewCompareStyleNames (global variable from RVStyle.pas). By default, style names are ignored when comparing styles, so, when merging style collections from the inserted RVF files, if a style with identical attributes but different name already exists, a style from file will not be added, and items using this style will not be read properly.
But before making any editing operation that can add style, you need to reset it back to True temporary.

3) In the current version, list markers do not use style names to save indices in ListStyles. It will be implemented in the next update.

Thanks Sergey. I have to save with style names for another section of the application, where these mini-documents share two or three global styles, which must be changed centrally sometimes; so the streams I have are saved with stylenames. I don't need to use the style names when I append them all together, though, so maybe there's a way to stream them into an RVE, and out to a stream again, without the stylenames. That might do the job.

Cheers,
Martin

An update on this:

Setting RichViewCompareStyleNames to True doesn't help; the same errors occur. So I'm still a bit stuck here. I guess I'll have to wait for the fix to be released.

Cheers,
Martin

[Sergey Tkachenko]

Did you update TrichView to the latest version? this problem must be fixed

[martindholmes]

I'm just in the process of doing that. I hadn't noticed the new release.

Thanks,
Martin
