Request handler response in a custom view of form

Hi All,

Request your valuable inputs, as i am stuck and not able to find a way out. As per my requirement, I need to do the following:

1. User clicks on the custom function menu of a document, this opens a custom cmd "Submit for Review".

2. "Submit for Review" cmd will present one basic web lingo file to make a division location selection after that user clicks on the button on this page which will call a request handler.

3. The request handler will do some background calculations and ultimately collect some data.

4. After this the request handler has to do redirection to a predefined Form (custom view).

5. But this form view should be populated on render with values calculated in Step 2.

I am not sure how to achieve this, a request handler can return a weblingo file, or do a redirect, or return an error file. I want the data collected in Step 2 to be available in the form custom view on render. This data user selects and submits the form and this starts the workflow.

Request you to please share any previous experience in this kind of use case.

Basically I need the request handler to collect some data and then redirect to a form custom view in edit mode with population (from the data collected by request handler) happening for the fields in the form.

Regards,

Arun

If you Create a Form Template,attach its mechanism to a table where each submit writes a row into that,would not that suffice as your data collection mechanism,so you would not have to code these yourself?Can you do your calculations in the browser using javascript right before submission?

Have your custom view as a View of this template when it paints would it not have the data from the SQLrow of what it is based on?

Now all you would need is a webnode cmd object/webnodeaction object that calls the concerned form and re-direct to a customview?

You could design everything with anchor href's and get most of the logic you want perfected,then after you have done that you could start looking at examples of builder snippets or attend some developer training?

That's how I would have attempted it not sure if I see your requirements right or not though

Maybe the functionality provided by LLIAPI:CacheUtil can help: this allows to store some data in the database (temporarily) and you can pass the "cache id" to the next request handler.

Just to clarify the requirement. I am not looking for help on creating custom node command from a document node.

I am at the point where I have clicked a custom cmd from a document function menu, and a weblingo file is presented, where a user selects the division loaction. This part is done.

Now on the weblingo file which was presented to the user, I am giving a button to move further in the use case. On click of that button, a request handler will be called which will do some calculations like read some xml and collect some data using node Id from where i invoked the custom command etc. This data calculation is not from a form data, but this I am calulcating in a custom request handler.

Once I am done with this part, I need to send this data which is quite a lot like reviewer/approver names, some default values read from a XML file etc. needs to be pushed on to a form (with a custom view, this form will always will be the same id). This data needs to be available on render of that form. Mind you, this data I am not reading from a form, but from a custom request handler described above and should be available in the form view on render, so that those can be set on the form fields. This will allow the user to make the selection of those data in the form and then submit the form. On submit of the form, a workflow will be initiated, which I have configured with the submission mechanism of the form being used in the use case.

I have seen some guidance where you can push data from a request handler objects to the response HTML file. But in my requirment, the response of the request handler is to redirect to a custom view of a predefined form where data from the request handler is pre-populated on the form view. I hope this clarifies the use case.

Sorry abt being so verbose, but i really need some urgent input on this. Like:

1. Do I have to override the out of box WebForm object request handlers.

2. Or i can do a redirection to a form from a request handler from backend by passing relevant parameters for Web form formedit request handler.

3. Or the data can be available in the form custom view as it is available in the weblingo files. i am not sure.

Please reply as soon as possible. Thank you.

A RH consists of a feature called .flocation,most of the times you would have seen something that is web escaped called NextURL

.Most times the RH after performing stuff moves to the location you specify.

If I invoke the RH of a Form in any system you will see a lot of pathing and gibberish but for you to understand anything in livelink has a web address

followed by the script(llisapi.dll,livelink.exe) after that a ? mark which starts the post/get params of a http request.

http://<LLURL>/livelink.exe?func=ll&viewid=169168120&readonly=false&sedit=false&objId=149729146&objAction=EditForm&nexturl=/livelink.exe?func=ll&objId=105360498&objAction=browse&sort=name

Now if I put the .flocation to that part func=ll&viewid=169168120&readonly=false&sedit=false&objId=149729146&objAction=EditForm

then it would invoke the OOB Form actions.Just observe actions of livelink the post/request what you get in builder or in the browser it may not be that difficult

So now what remains is how do I pass my data to the form and map it.The correct implementation would be in my first RH I would have a .fData feature that holds the values to the Form that you need to fill.

You can certainly do that and it is not going to be very easy if you are a beginner.

An alternative way and frankly I did not test this part is on that .flocation you just tack on that as additional params.

an e.g func=ll&viewid=169168120&

readonly=false&sedit=false&objId=149729146&objAction=EditForm&myval1=1234&myval2=134567&myval3=appu and so on

So if LL does not discard your additional params,when the form actually comes up in your browser those values can be retrieved as query string variables.

you would use javascript and then find the places like these

<span class="label"><input id="_1_1_18_1" name="_1_1_18_1" class="fullWidthTopAlign" type="text" value="[LL_FormTag_1_1_18_1 /]" />

I read that line as [LL_FormTag_1_1_18_1 /] replace that with the value held in that form template thing so if the request vars does work then you can put it there

PS:We all subscribe/read/answer thinking that the consumer will actually try things and are not going to design/research the solution for you so rather than having questions try/research some stuff and see where you are getting stuck.Most times I answer I do not assume what the user knows or has done before so I try to be a little more descriptive thinking it may be useful.But rarely will you get all your design questions answered in any forums the way exactly you want your project to work.

Hi eLink/Appu Nair, Hi Carsten Kulms, I really appreciate your responses and Appu's quite detailed response. I will try out your approcahes and see where i get to. Actually, I am short on time and bit of a beginner in OScript, so i thought i will take a expert opinion from you guys and the developer community. Thank you again for your responses. Best Regards, Arun
