- Collabora Online requires POST request with WOPISrc in form body
- GET requests with query parameters cause 400 Bad Request
- Using modern /cool/ endpoint with form submission to iframe
- Use window load event to ensure form element exists before submission
- Add allow-popups-to-escape-sandbox for cross-origin form POSTs
- Add allow-presentation for better compatibility
- Improved error logging for debugging form submission issues
- Collabora requires POST request to /loleaflet/dist/loleaflet.html
- WOPISrc must be in request body as form parameter
- Form targets iframe by name for proper document loading
- Matches WOPI/Collabora standard integration pattern
- Changed from form POST submission to direct iframe load
- WOPISrc goes in Collabora URL query string, not as form parameter
- This matches Collabora's expected request format for WOPI integration
- The collaboraProxyHandler endpoint is intentionally meant to load in an iframe
- X-Frame-Options: SAMEORIGIN was blocking cross-origin iframe loads
- Removed the header to allow the Flutter web frontend to embed the proxy page
- Inject script element into head that creates and submits form
- Script executes immediately when loaded, doesn't rely on Future callbacks
- Form targets iframe by name, WOPISrc in body not query params
- This ensures form submission happens reliably before any async operations
- Data URL iframe form submission was blocked by CORS
- New approach: create iframe in viewport, form in document body
- Form targets iframe by name, submits WOPISrc to loleaflet.html via POST
- Form submission happens in parent document context, not sandboxed iframe
- This avoids CORS issues and ensures form actually submits
- Create iframe with data URL containing HTML page
- HTML page has form that auto-submits to loleaflet.html with WOPISrc in body
- This ensures POST request instead of GET
- Form submits within iframe context, not affected by parent page JavaScript
- Remove URL building with query parameters that was causing GET requests
- Pass WOPISrc directly to _buildCollaboraIframe function
- JavaScript now creates form with POST method and WOPISrc in body
- This ensures Collabora receives POST not GET request
- Collabora expects POST to loleaflet.html with WOPISrc in body, not GET
- Previous Dart form.submit() wasn't executing reliably
- Use ScriptElement to inject and execute form submission JavaScript
- This bypasses Dart's HTML layer limitations and ensures form POSTs properly
- Unique viewType names with timestamp to avoid registration conflicts
- Changed from manual string concatenation to Uri.parse().replace(queryParameters: ...)
- This properly encodes the WOPISrc while maintaining encoding through iframe.src
- Fixes Collabora 'WOPISrc validation error: unencoded WOPISrc' warning
- Uri API ensures query parameters are properly percent-encoded
- WOPISrc is a full URL that needs URL encoding when passed as query param
- Use Uri.encodeComponent() to properly encode the WOPISrc value
- Simplify iframe setup to just use the properly constructed URL
- This fixes the 400 Bad Request from Collabora when loading documents
- Reverted to direct iframe src approach instead of form submission
- This avoids 'Form submission canceled' error
- Removed allow-same-origin from sandbox to improve security
- Added allow-popups-to-escape-sandbox for Collabora functionality
- Use direct URL with WOPISrc parameter instead of POST form
- Collabora's loleaflet.html expects WOPISrc as POST parameter, not URL query param
- Changed from iframe with src= to form submission approach
- Extract WOPISrc from URL and pass as hidden form input
- This avoids 400 Bad Request from Collabora when using GET with URL params
- Added dart:html and dart:ui_web imports for iframe support
- Created _buildCollaboraIframe() method to register and display iframe
- Set proper sandbox and allow attributes for Collabora functionality
- Full-screen iframe embedding of Collabora Online document editor
- Replaces placeholder UI with actual document viewing capability
Go backend:
- Fix WOPI models file (remove duplicate package declaration and syntax errors)
- Add GetOrgMember method to database as alias for GetUserMembership
- Add UpdateFileSize method to database
- Remove unused net/url import from wopi_handlers.go
- Fix field names in WOPI struct initializers (match JSON tags)
Flutter frontend:
- Remove webview_flutter import (use simpler placeholder for now)
- Fix _createWOPISession to safely access SessionBloc state
- Replace WebViewController usage with placeholder UI
- Remove unused _generateRandomHex methods from login/signup forms
- Add missing mimeType parameter to DocumentCapabilities in mock repository
- Remove unused local variables in file_browser_bloc
- Reverted WebViewWidget approach that was causing null check errors
- Show placeholder UI for Office documents until proper WOPI support is implemented
- Fixed web/index.html to only load PixelatedElegance font that actually exists
- Removed references to non-existent fonts causing OTS parsing errors
